Chapter I

MYSTERIOUS SOUNDS

BANG! Bang!

The pistol shots were almost simultaneous. A cow peacefully grazing
fifty yards away received one of the bullets in her back. She had
nothing to do with the quarrel all the same.

Neither of the adversaries was hit.

Who were these two gentlemen? We do not know, although this would be
an excellent opportunity to hand down their names to posterity. All
we can say is that the elder was an Englishman and the younger an
American, and both of them were old enough to know better.

So far as recording in what locality the inoffensive ruminant had
just tasted her last tuft of herbage, nothing can be easier. It was
on the left bank of Niagara, not far from the suspension bridge which
joins the American to the Canadian bank three miles from the falls.

The Englishman stepped up to the American.

"I contend, nevertheless, that it was 'Rule Britannia!'"

"And I say it was 'Yankee Doodle!'" replied the young American.

The dispute was about to begin again when one of the seconds -
doubtless in the interests of the milk trade - interposed.

"Suppose we say it was 'Rule Doodle' and 'Yankee Britannia' and
adjourn to breakfast?"

This compromise between the national airs of Great Britain and the
United States was adopted to the general satisfaction. The Americans
and Englishmen walked up the left bank of the Niagara on their way to
Goat Island, the neutral ground. between the falls. Let us leave them
in the presence of the boiled eggs and traditional ham, and floods
enough of tea to make the cataract jealous, and trouble ourselves no
more about them. It is extremely unlikely that we shall again meet
with them in this story.

Which was right; the Englishman or the American? It is not easy to
say. Anyhow the duel shows how great was the excitement, not only in
the new but also in the old world, with regard to an inexplicable
phenomenon which for a month or more had driven everybody to
distraction.

Never had the sky been so much looked at since the appearance of man
on the terrestrial globe. The night before an aerial trumpet had
blared its brazen notes through space immediately over that part of
Canada between Lake Ontario and Lake Erie. Some people had heard
those notes as "Yankee Doodle," others had heard them as "Rule
Britannia," and hence the quarrel between the Anglo-Saxons, which
ended with the breakfast on Goat Island. Perhaps it was neither one
nor the other of these patriotic tunes, but what was undoubted by all
was that - these extraordinary sounds had seemed to descend from the
sky to the earth.

What could it be? Was it some exuberant aeronaut rejoicing on that
sonorous instrument of which the Renommйe makes such obstreperous use?

No! There was no balloon and there were no aeronauts. Some strange
phenomenon had occurred in the higher zones of the atmosphere, a
phenomenon of which neither the nature nor the cause could be
explained. Today it appeared over America; forty-eight hours
afterwards it was over Europe; a week later it was in Asia over the
Celestial Empire.

Hence in every country of the world - empire, kingdom, or republic -
there was anxiety which it was important to allay. If you hear in
your house strange and inexplicable noises, do you not at once
endeavor to discover the cause? And if your search is in vain, do you
not leave your house and take up your quarters in another? But in
this case the house was the terrestrial globe! There are no means of
leaving that house for the moon - or Mars, or Venus, or Jupiter, or
any other planet of the solar system. And so of necessity we have to
find out what it is that takes place, not in the infinite void, but
within the atmospherical zones. In fact, if there is no air there is
no noise, and as there was a noise - that famous trumpet, to wit -
the phenomenon must occur in the air, the density of which invariably
diminishes, and which does not extend for more than six miles round
our spheroid.

Naturally the newspapers took up the question in their thousands, and
treated it in every form, throwing on it both light and darkness,
recording many things about it true or false, alarming and
tranquillizing their readers - as the sale required - and almost
driving ordinary people mad. At one blow party politics dropped
unheeded - and the affairs of the world went on none the worse for it.

But what could this thing be? There was not an observatory that was
not applied to. If an observatory could not give a satisfactory
answer what was the use of observatories? If astronomers, who doubled
and tripled the stars a hundred thousand million miles away, could
not explain a phenomenon occurring only a few miles off, what was the
use of astronomers?

The observatory at Paris was very guarded in what it said. In the
mathematical section they had not thought the statement worth
noticing; in the meridional section they knew nothing about it; in
the physical observatory they had not come across it; in the geodetic
section they had had no observation; in the meteorological section
there had been no record; in the calculating room they had had
nothing to deal with. At any rate this confession was a frank one,
and the same frankness characterized the replies from the observatory
of Montsouris and the magnetic station in the park of St. Maur. The
same respect for the truth distinguished the Bureau des Longitudes.

The provinces were slightly more affimative. Perhaps in the night of
the fifth and the morning of the sixth of May there bad appeared a
flash of light of electrical origin which lasted about twenty
seconds. At the Pic du Midi this light appeared between nine and ten
in the evening. At the Meteorological Observatory on the Puy de Dome
the light had been observed between one and two o'clock in the
morning; at Mont Ventoux in Provence it had been seen between two and
three o'clock; at Nice it had been noticed between three and four
o'clock; while at the Semnoz Alps between Annecy, Le Bourget, and Le
Lйman, it had been detected just as the zenith was paling with the
dawn.

Now it evidently would not do to disregard these observations
altogether. There could be no doubt that a light had been observed at
different places, in succession, at intervals, during some hours.
Hence, whether it had been produced from many centers in the
terrestrial atmosphere, or from one center, it was plain that the
light must have traveled at a speed of over one hundred and twenty
miles an hour.

In the United Kingdom there was much perplexity. The observatories
were not in agreement. Greenwich would not consent to the proposition
of Oxford. They were agreed on one point, however, and that was: "It
was nothing at all!"

But, said one, "It was an optical illusion!" While the, other
contended that, "It was an acoustical illusion!" And so they
disputed. Something, however, was, it will be seen, common to both
"It was an illusion."

Between the observatory of Berlin and the observatory of Vienna the
discussion threatened to end in international complications; but
Russia, in the person of the director of the observatory at Pulkowa,
showed that both were right. It all depended on the point of view
from which they attacked the phenomenon, which, though impossible in
theory, was possible in practice.

In Switzerland, at the observatory of Sautis in the canton of
Appenzell, at the Righi, at the Gдbriss, in the passes of the St.
Gothard, at the St. Bernard, at the Julier, at the Simplon, at
Zurich, at Somblick in the Tyrolean Alps, there was a very strong
disinclination to say anything about what nobody could prove - and
that was nothing but reasonable.

But in Italy, at the meteorological stations on Vesuvius, on Etna in
the old Casa Inglesi, at Monte Cavo, the observers made no hesitation
in admitting the materiality of the phenomenon, particularly as they
had seen it by day in the form of a small cloud of vapor, and by
night in that of a shooting star. But of what it was they knew
nothing.

Scientists began at last to tire of the mystery, while they continued
to disagree about it, and even to frighten the lowly and the
ignorant, who, thanks to one of the wisest laws of nature, have
formed, form, and will form the immense majority of the world's
inhabitants. Astronomers and meteorologists would soon have dropped
the subject altogether had not, on the night of the 26th and 27th,
the observatory of Kautokeino at Finmark, in Norway, and during the
night of the 28th and 29th that of Isfjord at Spitzbergen - Norwegian
one and Swedish the other - found themselves agreed in recording that
in the center of an aurora borealis there had appeared a sort of huge
bird, an aerial monster, whose structure they were unable to
determine, but who, there was no doubt, was showering off from his
body certain corpuscles which exploded like bombs.

In Europe not a doubt was thrown on this observation of the stations
in Finmark and Spitzbergen. But what appeared the most phenomenal
about it was that the Swedes and Norwegians could find themselves in
agreement on any subject whatever.

There was a laugh at the asserted discovery in all the observatories
of South America, in Brazil, Peru, and La Plata, and in those of
Australia at Sydney, Adelaide, and Melbourne; and Australian laughter
is very catching.

To sum up, only one chief of a meteorological station ventured on - a
decided answer to this question, notwithstanding the sarcasms that
his solution provoked. This was a Chinaman, the director of the
observatory at Zi-Ka-Wey which rises in the center of a vast plateau
less than thirty miles from the sea, having an immense horizon and
wonderfully pure atmosphere. "It is possible," said he, "that the
object was an aviform apparatus - a flying machine!"

What nonsense!

But if the controversy was keen in the old world, we can imagine what
it was like in that portion of the new of which the United States
occupy so vast an area.

A Yankee, we know, does not waste time on the road. He takes the
street that leads him straight to his end. And the observatories of
the American Federation did not hesitate to do their best. If they
did not hurl their objectives at each other's heads, it was because
they would have had to put them back just when they most wanted to
use them. In this much-disputed question the observatories of
Washington in the District of Columbia, and Cambridge in
Massachusetts, found themselves opposed by those of Dartmouth College
in New Hampshire, and Ann Arbor in Michigan. The subject of their
dispute was not the nature of the body observed, but the precise
moment of its observation. All of them claimed to have seen it the
same night, the same hour, the same minute, the same second, although
the trajectory of the mysterious voyager took it but a moderate
height above the horizon. Now from Massachusetts to Michigan, from
New Hampshire to Columbia, the distance is too great for this double
observation, made at the same moment, to be considered possible.

Dudley at Albany, in the state of New York, and West Point, the
military academy, showed that their colleagues were wrong by an
elaborate calculation of the right ascension and declination of the
aforesaid body.

But later on it was discovered that the observers had been deceived
in the body, and that what they had seen was an aerolite. This
aerolite could not be the object in question, forhow could an
aerolite blow a trumpet?

It was in vain that they tried to get rid of this trumpet as an
optical illusion. The ears were no more deceived than the eyes.
Something had assuredly been seen, and something had assuredly been
heard. In the night of the 12th and 13th of May - a very dark night -
the observers at Yale College, in the Sheffield Science School, had
been able to take down a few bars of a musical phrase in D major,
common time, which gave note for note, rhythm for rhythm, the chorus
of the Chant du Dйpart.

"Good," said the Yankee wags. "There is a French band well up in the
air."

"But to joke is not to answer." Thus said the observatory at Boston,
founded by the Atlantic Iron Works Society, whose opinions in matters
of astronomy and meteorology began to have much weight in the world
of science.

Then there intervened the observatory at Cincinnati, founded in 1870,
on Mount Lookout, thanks to the generosity of Mr. Kilgour, and known
for its micrometrical measurements of double stars. Its director
declared with the utmost good faith that there had certainly been
something, that a traveling body had shown itself at very short
periods at different points in the atmosphere, but what were the
nature of this body, its dimensions, its speed, and its trajectory,
it was impossible to say.

It was then a journal whose publicity is immense - the _New York
Herald_ - received the anonymous contribution hereunder.

"There will be in the recollection of most people the rivalry which
existed a few years ago between the two heirs of the Begum of
Ragginahra, the French doctor Sarrasin, the city of Frankville, and
the German engineer Schultze, in the city of Steeltown, both in the
south of Oregon in the United States.

"It will not have been forgotten that, with the object of destroying
Frankville, Herr Schultze launched a formidable engine, intended to
beat down the town and annihilate it at a single blow.

"Still less will it be forgotten that this engine, whose initial
velocity as it left the mouth of the monster cannon had been
erroneously calculated, had flown off at a speed exceeding by sixteen
times that of ordinary projectiles - or about four hundred and fifty
miles an hour - that it did not fall to the ground, and that it
passed into an aerolitic stag, so as to circle for ever rLd our globe.

"Why should not this be the body in question?"

Very ingenious, Mr. Correspondent on the _New York Herald!_ but how
about the trumpet? There was no trumpet in Herr Schulze's projectile!

So all the explanations explained nothing, and all the observers had
observed in vain. There remained only the suggestion offered by the
director of Zi-Ka-Wey. But the opinion of a Chinaman!

The discussion continued, and there was no sign of agreement. Then
came a short period of rest. Some days elapsed without any object,
aerolite or otherwise, being described, and without any trumpet notes
being heard in the atmosphere. The body then had fallen on some part
of the globe where it had been difficult to trace it; in the sea,
perhaps. Had it sunk in the depths of the Atlantic, the Pacific, or
the Indian Ocean? What was to be said in this matter?

But then, between the 2nd and 9th of June, there came a new series of
facts which could not possibly be explained by the unaided existence
of a cosmic phenomenon.

In a week the Hamburgers at the top of St. Michael's Tower, the Turks
on the highest minaret of St. Sophia, the Rouennais at the end of the
metal spire of their cathedral, the Strasburgers at the summit of
their minister, the Americans on the head of the Liberty statue at
the entrance of the Hudson and on the Bunker Hill monument at Boston,
the Chinese at the spike of the temple, of the Four Hundred Genii at
Canton, the Hindus on the sixteenth terrace of the pyramid of the
temple at Tanjore, the San Pietrini at the cross of St. Peter's at
Rome, the English at the cross of St. Paul's in London, the Egyptians
at the appex of the Great Pyramid of Ghizeh, the Parisians at the
lighting conductor of the iron tower of the Exposition of 1889, a
thousand feet high, all of them beheld a flag floating from some one
of these inaccessible points.

And the flag was black, dotted with stars, and it bore a golden sun
in its center.

Chapter II

AGREEMENT IMPOSSIBLE

"And the first who says the contrary - "

"Indeed! But we will say the contrary so long as there is a place to
say it in!"

"And in spite of your threats - "

"Mind what you are saying, Bat Fynn!"

"Mind what you are saying, Uncle Prudent!"

"I maintain that the screw ought to be behind!"

"And so do we! And so do we!" replied half a hundred voices
confounded in one.

"No! It ought to be in front!" shouted Phil Evans.

"In front!" roared fifty other voices, with a vigor in no whit less
remarkable.

"We shall never agree!"

"Never! Never!"

"Then what is the use of a dispute?"

"It is not a dispute! It is a discussion!"

One would not have thought so to listen to the taunts, objurgations,
and vociferations which filled the lecture room for a good quarter of
an hour.

The room was one of the largest in the Weldon Institute, the
well-known club in Walnut Street, Philadelphia, Pennsylvania, U. S.
A. The evening before there had been an election of a lamplighter,
occasioning many public manifestations, noisy meetings, and even
interchanges of blows, resulting in an effervescence which had not
yet subsided, and which would account for some of the excitement just
exhibited by the members of the Weldon Institute. For this was merely
a meeting of balloonists, discussing the burning question of the
direction of balloons.

In this great saloon there were struggling, pushing, gesticulating,
shouting, arguing, disputing, a hundred balloonists, all with their
hats on, under the authority of a president, assisted by a secretary
and treasurer. They were not engineers by profession, but simply
amateurs of all that appertained to aerostatics, and they were
amateurs in a fury, and especially foes of those who would oppose to
aerostats "apparatuses heavier than the air," flying machines, aerial
ships, or what not. That these people might one day discover the
method of guiding balloons is possible. There could be no doubt that
their president had considerable difficulty in guiding them.

This president, well known in Philadelphia was the famous Uncle
Prudent, Prudent being his family name. There is nothing surprising
in America in the qualificative uncle, for you can there be uncle
without having either nephew or niece. There they speak of uncle as
in other places they speak of father, though the father may have had
no children.

Uncle Prudent was a personage of consideration, and in spite of his
name was well known for his audacity. He was very rich, and that is
no drawback even in the United States; and how could it be otherwise
when he owned the greater part of the shares in Niagara Falls? A
society of engineers had just been founded at Buffalo for working the
cataract. It seemed to be an excellent speculation. The seven
thousand five hundred cubic meters that pass over Niagara in a second
would produce seven millions of horsepower. This enormous power,
distributed amongst all the workshops within a radius of three
hundred miles, would return an annual income of three hundred million
dollars, of which the greater part would find its way into the pocket
of Uncle Prudent. He was a bachelor, he lived quietly, and for his
only servant had his valet Frycollin, who was hardly worthy of being
the servant to so audacious a master.

Uncle Prudent was rich, and therefore he had friends, as was natural;
but he also had enemies, although he was president of the club -
among others all those who envied his position. Amongst his bitterest
foes we may mention the secretary of the Weldon Institute.

This was Phil Evans, who was also very rich, being the manager of the
Wheelton Watch Company, an important manufactory, which makes every
day five hundred movements equal in every respect to the best Swiss
workmanship. Phil Evans would have passed for one of the happiest men
in the world, and even in the United States, if it had not been for
Uncle Prudent. Like him he was in his forty-sixth year; like him of
invariable health; like him of undoubted boldness. They were two men
made to understand each other thoroughly, but they did not, for both
were of extreme violence of character. Uncle Prudent was furiously
hot; Phil Evans was abnormally cool.

And why had not Phil Evans been elected president of the club? The
votes were exactly divided between Uncle Prudent and him. Twenty
times there had been a scrutiny, and twenty times the majority had
not declared for either one or the other. The position was
embarrassing, and it might have lasted for the lifetime of the
candidates.

One of the members of the club then proposed a way out of the
difficulty. This was Jem Chip, the treasurer of the Weldon Institute.
Chip was a confirmed vegetarian, a proscriber of all animal
nourishment, of all fermented liquors, half a Mussulman, half a
Brahman. On this occasion Jem Chip was supported by another member of
the club, William T. Forbes, the manager of a large factory where
they made glucose by treating rags with sulphuric acid. A man of good
standing was this William T. Forbes, the father of two charming girls
- Miss Dorothy, called Doll, and Miss MMartha, called Mat, who gave
the tone to the best society in Philadelphia.

It followed, then, on the proposition of Jem Chip, supported by
William T. Forbes and others, that it was decided to elect the
president "on the center point."

This mode of election can be applied in all cases when it is desired
to elect the most worthy; and a number of Americans of high
intelligence are already thinking of employing it in the nomination
of the President of the Republic of the United States.

On two boards of perfect whiteness a black line is traced. The length
of each of these lines is mathematically the same, for they have been
determined with as much accuracy as the base of the first triangle in
a trigonometrical survey. That done, the two boards were erected on
the same day in the center of the conference room, and the two
candidates, each armed with a fine needle, marched towards the board
that had fallen to his lot. The man who planted his needle nearest
the center of the line would be proclaimed President of the Weldon
Institute.

The operation must be done at once - no guide marks or trial shots
allowed; nothing but sureness of eye. The man must have a compass in
his eye, as the saying goes; that was all.

Uncle Prudent stuck in his needle at the same moment as Phil Evans
did his. Then there began the measurement to discover which of the
two competitors had most nearly approached the center.

Wonderful! Such had been the precision of the shots that the measures
gave no appreciable difference. If they were not exactly in the
mathematical center of the line, the distance between the needles was
so small as to be invisible to the naked eye.

The meeting was much embarrassed.

Fortunately one of the members, Truck Milnor, insisted that the
measurements should be remade by means of a rule graduated by the
micrometrical machine of M. Perreaux, which can divide a millimeter
into fifteen-hundreths of a millimeter with a diamond splinter, was
brought to bear on the lines; and on reading the divisions through a
microscope the following were the results: Uncle Prudent had
approached the center within less than six fifteenth-hundredths of a
millimeter. Phil Evans was within nine fifteen-hundredths.

And that is why Phil Evans was only secretary of the Weldon
Institute, whereas Uncle Prudent was president. A difference of three
fifteen-hundredths of a millimeter! And on account of it Phil Evans
vowed against Uncle Prudent one of those hatreds which are none the
less fierce for being latent.

Chapter III

A VISITOR IS ANNOUNCED

The many experiments made during this last quarter of the nineteenth
century have given considerable impetus to the question of guidable
balloons. The cars furnished with propellers attached in 1852 to the
aerostats of the elongated form introduced by Henry Giffard, the
machines of Dupuy de Lome in 1872, of the Tissandier brothers in
1883, and of Captain Krebs and Renard in 1884, yielded many important
results. But if these machines, moving in a medium heavier than
themselves, maneuvering under the propulsion of a screw, working at
an angle to the direction of the wind, and even against the wind, to
return to their point of departure, had been really "guidable," they
had only succeeded under very favorable conditions. In large, covered
halls their success was perfect. In a calm atmosphere they did very
well. In a light wind of five or six yards a second they still moved.
But nothing practical had been obtained. Against a miller's wind -
nine yards a second - the machines had remained almost stationary.
Against a fresh breeze - eleven yards a second - they would have
advanced backwards. In a storm - twenty-seven to thirty-three yards a
second - they would have been blown about like a feather. In a
hurricane - sixty yards a second - they would have run the risk of
being dashed to pieces. And in one of those cyclones which exceed a
hundred yards a second not a fragment of them would have been left.
It remained, then, even after the striking experiments of Captains
Krebs and Renard, that though guidable aerostats had gained a little
speed, they could not be kept going in a moderate breeze. Hence the
impossibility of making practical use of this mode of aerial
locomotion.

With regards to the means employed to give the aerostat its motion a
great deal of progress had been made. For the steam engines of Henry
Giffard, and the muscular force of Dupuy de Lome, electric motors had
gradually been substituted. The batteries of bichromate of potassium
of the Tissandier brothers had given a speed of four yards a second.
The dynamo-electric machines of Captain Krebs and Renard had
developed a force of twelve horsepower and yielded a speed of six and
a half yards per second.

With regard to this motor, engineers and electricians had been
approaching more and more to that desideratum which is known as a
steam horse in a watch case. Gradually the results of the pile of
which Captains Krebs and Renard had kept the secret had been
surpassed, and aeronauts had become able to avail themselves of
motors whose lightness increased at the same time as their power.

In this there was much to encourage those who believed in the
utilization of guidable balloons. But yet how many good people there
are who refuse to admit the possibility of such a thing! If the
aerostat finds support in the air it belongs to the medium in which
it moves; under such conditions, how can its mass, which offers so
much resistance to the currents of the atmosphere, make its way
against the wind?

In this struggle of the inventors after a light and powerful motor,
the Americans had most nearly attained what they sought. A
dynamo-electric apparatus, in which a new pile was employed the
composition of which was still a mystery, had been bought from its
inventor, a Boston chemist up to then unknown. Calculations made with
the greatest care, diagrams drawn with the utmost exactitude, showed
that by means of this apparatus driving a screw of given dimensions a
displacement could be obtained of from twenty to twenty-two yards a
second.

Now this was magnificent!

"And it is not dear," said Uncle Prudent, as he handed to the
inventor in return for his formal receipt the last installment of the
hundred thousand paper dollars he had paid for his invention.

Immediately the Weldon Institute set to work. When there comes along
a project of practical utility the money leaps nimbly enough from
American pockets. The funds flowed in even without its being
necessary to form a syndicate. Three hundred thousand dollars came
into the club's account at the first appeal. The work began under the
superintendence of the most celebrated aeronaut of the United States,
Harry W. Tinder, immortalized by three of his ascents out of a
thousand, one in which he rose to a height of twelve thousand yards,
higher than Gay Lussac, Coxwell Sivet, Crocй-Spinelli, Tissandier,
Glaisher; another in which he had crossed America from New York to
San Francisco, exceeding by many hundred leagues the journeys of
Nadar, Godard, and others, to say nothing of that of John Wise, who
accomplished eleven hundred and fifty miles from St. Louis to
Jefferson county; the third, which ended in a frightful fall from
fifteen hundred feet at the cost of a slight sprain in the right
thumb, while the less fortunate Pilвtre de Rozier fell only seven
hundred feet, and yet killed himself on the spot!

At the time this story begins the Weldon institute had got their work
well in hand. In the Turner yard at Philadelphia there reposed an
enormous aerostat, whose strength had been tried by highly compressed
air. It well merited the name of the monster balloon.

How large was Nadar's Gйant? Six thousand cubic meters. How large was
John Wise's balloon? Twenty thousand cubic meters. How large was the
Giffard balloon at the 1878 Exhibition? Twenty-five thousand cubic
meters. Compare these three aerostats with the aerial machine of the
Weldon Institute, whose volume amounted to forty thousand cubic
meters, and you will understand why Uncle Prudent and his colleagues
were so justifiably proud of it.

This balloon not being destined for the exploration of the higher
strata of the atmosphere, was not called the Excelsior, a name which
is rather too much held in honor among the citizens of America. No!
It was called, simply, the _Go-Ahead,_ and all it had to do was to
justify its name by going ahead obediently to the wishes of its
commander.

The dynamo-electric machine, according to the patent purchased by the
Weldon Institute, was nearly ready. In less than six weeks the
_Go-Ahead_ would start for its first cruise through space.

But, as we have seen, all the mechanical difficulties had not been
overcome. Many evenings had been devoted to discussing, not the form
of its screw nor its, dimensions, but whether it ought to be put
behind, as the Tissandier brothers had done, or before as Captains
Krebs and Renard had done. It is unnecessary to add that the
partisans of the two systems had almost come to blows. The group of
"Beforists" were equaled in number by the group of "Behindists."
Uncle Prudent, who ought to have given the casting vote - Uncle
Prudent, brought up doubtless in the school of Professor Buridan -
could not bring himself to decide.

Hence the impossibility of getting the screw into place. The dispute
might last for some time, unless the government interfered. But in
the United States the government meddles with private affairs as
little as it possibly can. And it is right.

Things were in this state at this meeting on the 13th of June, which
threatened to end in a riot - insults exchanged, fisticuffs
succeeding the insults, cane thrashings succeeding the fisticuffs,
revolver shots succeeding the cane thrashings - when at thirty-seven
minutes past eight there occurred a diversion.

The porter of the Weldon Institute coolly and calmly, like a
policeman amid the storm of the meeting, approached the presidential
desk. On it he placed a card. He awaited the orders that Uncle
Prudent found it convenient to give.

Uncle Prudent turned on the steam whistle, which did duty for the
presidential bell, for even the Kremlin clock would have struck in
vain! But the tumult slackened not.

Then the president removed his hat. Thanks to this extreme measure a
semi-silence was obtained.

"A communication!" said Uncle Prudent, after taking a huge pinch from
the snuff-box which never left him.

"Speak up!" answered eighty-nine voices, accidentally in agreement on
this one point.

"A stranger, my dear colleagues, asks to be admitted to the meeting."

"Never!" replied every voice.

"He desires to prove to us, it would appear," continued Uncle
Prudent, 'that to believe in guiding balloons is to believe in the
absurdest of Utopias!"

"Let him in! Let him in!"

"What is the name of this singular personage?" asked secretary Phil
Evans.

"Robur," replied Uncle Prudent.

"Robur! Robur! Robur!" yelled the assembly. And the welcome accorded
so quickly to the curious name was chiefly due to the Weldon
Institute hoping to vent its exasperation on the head of him who bore
it!

Chapter IV

IN WHICH A NEW CHARACTER APPEARS

"Citizens of the United States! My name is Robur. I am worthy of the
name! I am forty years old, although I look but thirty, and I have a
constitution of iron, a healthy vigor that nothing can shake, a
muscular strength that few can equal, and a digestion that would be
thought first class even in an ostrich!"

They were listening! Yes! The riot was quelled at once by the totally
unexpected fashion of the speech. Was this fellow a madman or a
hoaxer? Whoever he was, he kept his audience in hand. There was not a
whisper in the meeting in which but a few minutes ago the storm was
in full fury.

And Robur looked the man he said he was. Of middle height and
geometric breadth, his figure was a regular trapezium with the
greatest of its parallel sides formed by the line of his shoulders.
On this line attached by a robust neck there rose an enormous
spheroidal head. The head of what animal did it resemble from the
point of view of passional analogy? The head of a bull; but a bull
with an intelligent face. Eyes which at the least opposition would
glow like coals of fire; and above them a permanent contraction of
the superciliary muscle, an invariable sign of extreme energy. Short
hair, slightly woolly, with metallic reflections; large chest rising
and falling like a smith's bellows; arms, hands, legs, feet, all
worthy of the trunk. No mustaches, no whiskers, but a large American
goatee, revealing the attachments of the jaw whose masseter muscles
were evidently of formidable strength. It has been calculated - what
has not been calculated? - that the pressure of the jaw of an
ordinary crocodile can reach four hundred atmospheres, while that of
a hound can only amount to one hundred. From this the following
curious formula has been deduced: If a kilogram of dog produces eight
kilograms of masseteric force, a kilogram of crocodile could produce
twelve. Now, a kilogram of, the aforesaid Robur would not produce
less than ten, so that he came between the dog and the crocodile.

From what country did this remarkable specimen come? It was difficult
to say. One thing was noticeable, and that was that he expressed
himself fluently in English without a trace of the drawling twang
that distinguishes the Yankees of New England.

He continued: "And now, honorable citizens, for my mental faculties.
You see before you an engineer whose nerves are in no way inferior to
his muscles. I have no fear of anything or anybody. I have a strength
of will that has never had to yield. When I have decided on a thing,
all America, all the world, may strive in vain to keep me from it.
When I have an idea, I allow no one to share it, and I do not permit
any contradiction. I insist on these details, honorable citizens,
because it is necessary you should quite understand me. Perhaps you
think I am talking too much about myself? It does not matter ff you
do! And now consider a little before you interrupt me, as I have come
to tell you something that you may not be particularly pleased to
hear."

A sound as of the surf on the beach began to rise along the first row
of seats - a sign that the sea would not be long in getting stormy
again.

"Speak, stranger!" said Uncle Prudent, who had some difficulty in
restraining himself.

And Robur spoke as follows, without troubling himself any more about
his audience.

"Yes! I know it well! After a century of experiments that have led to
nothing, and trials giving no results, there still exist ill-balanced
minds who believe in guiding balloons. They imagine that a motor of
some sort, electric or otherwise, might be applied to their
pretentious skin bags which are at the mercy of every current in the
atmosphere. They persuade themselves that they can be masters of an
aerostat as they can be masters of a ship on the surface of the sea.
Because a few inventors in calm or nearly calm weather have succeeded
in working an angle with the wind, or even beating to windward in a
gentle breeze, they think that the steering of aerial apparatus
lighter than the air is a practical matter. Well, now, look here; You
hundred, who believe in the realization of your dreams, are throwing
your thousands of dollars not into water but into space! You are
fighting the impossible!"

Strange as it was that at this affirmation the members of the Weldon
Institute did not move. Had they become as deaf as they were patient?
Or were they reserving themselves to see how far this audacious
contradictor would dare to go?

Robur continued: "What? A balloon! When to obtain the raising of a
couple of pounds you require a cubic yard of gas. A balloon
pretending to resist the wind by aid of its mechanism, when the
pressure of a light breeze on a vessel's sails is not less than that
of four hundred horsepower; when in the accident at the Tay Bridge
you saw the storm produce a pressure of eight and a half
hundredweight on a square yard. A balloon, when on such a system
nature has never constructed anything flying, whether furnished with
wings like birds, or membranes like certain fish, or certain mammalia
-"

"Mammalia?" exclaimed one of the members.

"Yes! Mammalia! The bat, which flies, if I am not mistaken! Is the
gentleman unaware that this flyer is a mammal? Did he ever see an
omelette made of bat's eggs?"

The interrupter reserved himself for future interruption, and Robur
resumed: "But does that mean that man is to give up the conquest of
the air, and the transformation of the domestic and political manners
of the old world, by the use of this admirable means of locomotion?
By no means. As he has become master of the seas with the ship, by
the oar, the sail, the wheel and the screw, so shall he become master
of atmospherical space by apparatus heavier than the air - for it
must be heavier to be stronger than the air!"

And then the assembly exploded. What a broadside of yells escaped
from all these mouths, aimed at Robur like the muzzles of so many
guns! Was not this hurling a declaration of war into the very camp of
the balloonists? Was not this a stirring up of strife between 'the
lighter" and 'the heavier" than air?

Robur did not even frown. With folded arms he waited bravely till
silence was obtained.

By a gesture Uncle Prudent ordered the firing to cease.

"Yes," continued Robur, 'the future is for the flying machine. The
air affords a solid fulcrum. If you will give a column of air an
ascensional movement of forty-five meters a second, a man can support
himself on the top of it if the soles of his boots have a superficies
of only the eighth of a square meter. And if the speed be increased
to ninety meters, he can walk on it with naked feet. Or if, by means
of a screw, you drive a mass of air at this speed, you get the same
result."

What Robur said had been said before by all the partisans of
aviation, whose work slowly but surely is leading on to the solution
of the problem. To Ponton d'Amйcourt, La Landelle, Nadar, De Luzy, De
Louvriй, Liais, Beleguir, Moreau, the brothers Richard, Babinet,
jobert, Du Temple, Salives, Penaud, De Villeneuve, Gauchot and Tatin,
Michael Loup, Edison, Planavergne, and so many others, belongs the
honor of having brought forward ideas of such simplicity. Abandoned
and resumed times without number, they are sure, some day to triumph.
To the enemies of aviation, who urge that the bird only sustains
himself by warming the air he strikes, their answer is ready. Have
they not proved that an eagle weighing five kilograms would have to
fill fifty cubic meters with his warm fluid merely to sustain himself
in space?

This is what Robur I demonstrated with undeniable logic amid the
uproar that arose on all sides. And in conclusion these are the words
he hurled in the faces of the balloonists: "With your aerostats you
can do nothing - you will arrive at nothing - you dare do nothing!
The boldest of your aeronauts, John Wise, although he has made an
aerial voyage of twelve hundred miles above the American continent,
has had to give up his project of crossing the Atlantic! And you have
not advanced one step - not one step - towards your end."

"Sir," said the president, who in vain endeavored to keep himself
cool, "you forget what was said by our immortal Franklin at the first
appearance of the fire balloon, "It is but a child, but it will
grow!" It was but a child, and it has grown.

"No, Mr. President, it has not grown! It has got fatter - and this is
not the same thing!"

This was a direct attack on the Weldon Institute, which bad decreed,
helped, and paid for the making of a monster balloon. And so
propositions of the following kind began to fly about the room: 'turn
him out!" 'throw him off the platform!" "Prove that he is heavier
than the air!"

But these were only words, not means to an end.

Robur remained impassible, and continued: "There is no progress for
your aerostats, my citizen balloonists; progress is for flying
machines. The bird flies, and he is not a balloon, he is a piece of
mechanism!"

"Yes, he flies!" exclaimed the fiery Bat T. Fynn; "but he flies
against all the laws of mechanics."

"Indeed!" said Robur, shrugging his shoulders, and resuming, "Since
we have begun the study of the flight of large and small birds one
simple idea has prevailed - to imitate nature, which never makes
mistakes. Between the albatross, which gives hardly ten beats of the
wing per minute, between the pelican, which gives seventy -"

"Seventy-one," said the voice of a scoffer.

"And the bee, which gives one hundred and ninety-two per second -"

"One hundred and ninety-three!" said the facetious individual.

"And, the common house fly, which gives three hundred and thirty -"

"And a half!"

"And the mosquito, which gives millions -"

"No, milliards!"

But Robur, the interrupted, interrupted not his demonstration.
"Between these different rates -" he continued.

"There is a difference," said a voice.

"There is a possibility of finding a practical solution. When De Lucy
showed that the stag beetle, an insect weighing only two grammes,
could lift a weight of four hundred grammes, or two hundred times its
own weight, the problem of aviation was solved. Besides, it has been
shown that the wing surface decreases in proportion to the increase
of the size and weight of the animal. Hence we can look forward to
such contrivances -"

"Which would never fly!" said secretary Phil Evans.

"Which have flown, and which will fly," said Robur, without being in
the least disconcerted, "and which we can call streophores,
helicopters, orthopters - or, in imitation of the word 'nef,' which
comes from 'navis,' call them from 'avis,' 'efs,' - by means of which
man will become the master of space. The helix -"

"Ah, the helix!" replied Phil Evans. "But the bird has no helix; that
we know!"

"So," said Robur; "but Penaud has shown that in reality the bird
makes a helix, and its flight is helicopteral. And the motor of the
future is the screw -"

"From such a maladee Saint Helix keep us free!" sung out one of the
members, who had accidentally hit upon the air from Herold's _Zampa._

And they all took up the chorus: "From such a maladee Saint Helix
keep us free!" with such intonations and variations as would have
made the French composer groan in his grave.

As the last notes died away in a frightful discord Uncle Prudent took
advantage of the momentary calm to say, "Stranger, up to now, we let
you speak without interruption." It seemed that for the president of
the Weldon Institute shouts, yells, and catcalls were not
interruptions, but only an exchange of arguments.

"But I may remind you, all the same, that the theory of aviation is
condemned beforehand, and rejected by the majority of American and
foreign engineers. It is a system which was the cause of the death of
the Flying Saracen at Constantinople, of the monk Volador at Lisbon,
of De Leturn in 1852, of De Groof in 1864, besides the victims I
forget since the mythological Icarus -"

"A system," replied Robur, "no more to be condemned than that whose
martyrology contains the -names of Pilвtre de Rozier at Calais, of
Blanchard at Paris, of Donaldson and Grimwood in Lake Michigan, of
Sivel and of Crocй-Spinelli, and others whom it takes good care, to
forget."

This was a counter-thrust with a vengeance.

"Besides," continued Robur, "With your balloons as good as you can
make them you will never obtain any speed worth mentioning. It would
take you ten years to go round the world - and a flying machine could
do it in a week!"

Here arose a new tempest of protests and denials which lasted for
three long minutes. And then Phil Evans look up the word.

"Mr. Aviator," he said "you who talk so much of the benefits of
aviation, have you ever aviated?"

"I have."

"And made the conquest of the air?"

"Not unlikely."

"Hooray for Robur the Conqueror!" shouted an ironical voice.

"Well, yes! Robur the Conqueror! I accept the name and I will bear
it, for I have a right to it!"

"We beg to doubt it!" said Jem Chip.

"Gentlemen," said Robur, and his brows knit, "when I have just
seriously stated a serious thing I do not permit anyone to reply to
me by a flat denial, and I shall be glad to know the name of the
interrupter."

"My name is Chip, and I am a vegetarian."

"Citizen Chip," said Robur, "I knew that vegetarians had longer
alimentary canals than other men - a good foot longer at the least.
That is quite long enough; and so do not compel me to make you any
longer by beginning at your ears and -"

"Throw him out."

"Into the street with him!"

"Lynch him!"

"Helix him!

The rage of the balloonists burst forth at last. They rushed at the
platform. Robur disappeared amid a sheaf of hands that were thrown
about as if caught in a storm. In vain the steam whistle screamed its
fanfares on to the assembly. Philadelphia might well think that a
fire was devouring one of its quarters and that all the waters of the
Schuyllkill could not put it out.

Suddenly there was a recoil in the tumult. Robur had put his hands
into his pockets and now held them out at the front ranks of the
infuriated mob.

In each hand was one of those American institutions known as
revolvers which the mere pressure of the fingers is enough to fire -
pocket mitrailleuses in fact.

And taking advantage not only of the recoil of his assailants but
also of the silence which accompanied it.

"Decidedly," said he, "it was not Amerigo that discovered the New
World, it was Cabot! You are not Americans, citizen balloonists! You
are only Cabo-"

Four or five shots cracked out, fired into space. They hurt nobody.
Amid the smoke, the engineer vanished; and when it had thinned away
there was no trace of him. Robur the Conqueror had flown, as if some
apparatus of aviation had borne him into the air.

Chapter V

ANOTHER DISAPPEARANCE

This was not the first occasion on which, at the end of their stormy
discussions, the members of the Weldon Institute had filled Walnut
Street and its neighborhood with their tumult. Several times had the
inhabitants complained of the noisy way in which the proceedings
ended, and more than once had the policemen had to interfere to clear
the thoroughfare for the passersby, who for the most part were
supremely indifferent on the question of aerial navigation. But never
before had the tumult attained such proportions, never had the
complaints been better founded, never had the intervention of the
police been more necessary.

But there was some excuse for the members of the Weldon Institute.
They had been attacked in their own house. To these enthusiasts for
"lighter than air" a no less enthusiast for "heavier than air" had
said things absolutely abhorrent. And at the moment they were about
to treat him as he deserved, he had disappeared.

So they cried aloud for vengeance. To leave such insults unpunished
was impossible to all with American blood in their veins. Had not the
sons of Amerigo been called the sons of Cabot? Was not that an insult
as unpardonable as it happened to be just - historically?

The members of the club in several groups rushed down Walnut Street,
then into the adjoining streets, and then all over the neighborhood.
They woke up the householders; they compelled them to search their
houses, prepared to indemnify them later on for the outrage on their
privacy. Vain were all their trouble and searching. Robur was nowhere
to be found; there was no trace of him. He might have gone off in the
_Go-Ahead,_ the balloon of the Institute, for all they could tell.
After an hour's hunt the members had to give in and separate, not
before they had agreed to extend their search over the whole
territory of the twin Americas that form the new continent.

By eleven o'clock quiet had been restored in the neighborhood of
Walnut Street. Philadelphia was able to sink again into that sound
sleep which is the privilege of non-manufacturing towns. The
different members of the club parted to seek their respective houses.
To mention the most distinguished amongst them, William T. Forbes
sought his large sugar establishment, where Miss Doll and Miss Mat
had prepared for him his evening tea, sweetened with his own glucose.
Truck Milnor took the road to his factory in the distant suburb,
where the engines worked day and night. Treasurer Jim Chip, publicly
accused of possessing an alimentary canal twelve, inches longer than
that of other men, returned to the vegetable soup that was waiting
for him.

Two of the most important bahoonists - two only - did not seem to
think of returning so soon to their domicile. They availed themselves
of the opportunity to discuss the question with more than usual
acrimony. These were the irreconcilables, Uncle Prudent and Phil
Evans, the president and secretary of the Weldon Institute.

At the door of the club the valet Frycollin waited for Uncle Prudent,
his master, and at last he went after him, though he cared but little
for the subject which had set the two colleagues at loggerheads.

It is only an euphemism' that the verb "discuss" can be used to
express the way in which the duet between the president and secretary
was being performed. As a matter of fact they were in full wrangle
with an energy bom of their old rivalry.

"No, Sir, no," said Phil Evans. "If I had had the honor of being
president of the Weldon Institute, there never, no, never, would have
been such a scandal."

"And what would you have done, if you had had the honor?" demanded
Uncle Prudent.

"I would have stopped the insulter before he had opened his mouth."

"It seems to me it would have been impossible to stop him until he
had opened his mouth," replied Uncle Prudent.

"Not in America, Sir; not in America."

And exchanging such observations, increasing in bitterness as they
went, they walked on through the streets farther and farther from
their homes, until they reached a part of the city whence they had to
go a long way round to get back.

Frycollin followed, by no means at ease to see his master plunging
into such deserted spots. He did not like deserted spots,
particularly after midnight. in fact the darkness was profound, and
the moon was only a thin crescent just beginning its monthly life.
Frycollin kept a lookout to the left and right of him to see if he
was followed. And he fancied he could see five or six hulking follows
dogging his footsteps. Instinctively he drew nearer to his master,
but not for the world would be have dared to break in on the
conversation of which the fragments reached him.

In short it so chanced that the president and secretary of the Weldon
Institute found themselves on the road to Fairmount Park. In the full
heat of their dispute they crossed the Schuyllkill river by the
famous iron bridge. They met only a few belated wayfarers, and
pressed on across a wide open tract where the immense prairie was
broken every now and then by the patches of thick woodland - which
make the park different to any other in the world.

There Frycollin's terror became acute, particularly as he saw the
five or six shadows gliding after him across the Schuyllkill bridge.
The pupils of his eyes broadened out to the circumference of his
iris, and his limbs seemed to diminish as if endowed with the
contractility peculiar to the mollusca and certain of the articulate;
for Frycollin, the valet, was an egregious coward.

He was a pure South Carolina Negro, with the head of a fool and the
carcass of an imbecille. Being only one and twenty, he had never been
a slave, not even by birth, but that made no difference to him.
Grinning and greedy and idle, and a magnificent poltroon, he had been
the servant of Uncle Prudent for about three years. Over and over
again had his master threatened to kick him out, but had kept him on
for fear of doing worse. With a master ever ready to venture on the
most audacious enterprises, Frycollin's cowardice had brought him
many arduous trials. But he had some compensation. Very little had
been said about his gluttony, and still less about his laziness.

Ah, Valet Frycollin, if you could only have read the future! Why, oh
why, Frycollin, did you not remain at Boston with the Sneffels, and
not have given them up when they talked of going to Switzerland? Was
not that a much more suitable place for you than this of Uncle
Prudent's, where danger was daily welcomed?

But here he was, and his master had become used to his faults. He had
one advantage, and that was a consideration. Although he was a Negro
by birth he did not speak like a Negro, and nothing is so irritating
as that hateful jargon in which all the pronouns are possessive and
all the verbs infinitive. Let it be understood, then,that Frycollin
was a thorough coward.

And now it was midnight, and the pale crescent of the moon began to
sink in the west behind the trees in the park. The rays streaming
fitfully through the branches made the shadows darker than ever.
Frycollin looked around him anxlously. "Brrr!" he said, "There are
those fellows there all the time. Positively they are getting nearer!
Master Uncle!" he shouted.

It was thus he called the president of the Weldon Institute, and thus
did the president desire to be called.

At the moment the dispute of the rivals had reached its maximum, and
as they hurled their epithets at each other they walked faster and
faster, and drew farther and farther away from the Schuyllkill
bridge. They had reached the center of a wide clump of trees, whose
summits were just tipped by the parting rays of the moon. Beyond the
trees was a very large clearing - an oval field, a complete
amphitheater. Not a hillock was there to hinder the gallop of the
horses, not a bush to stop the view of the spectators.

And if Uncle Prudent and Phil Evans had not been so deep in their
dispute, and had used their eyes as they were accustomed to, they
would have found the clearing was not in its usual state. Was it a
flour will that had anchored on it during the night? It looked like
it, with its wings and sails - motionless and mysterious in the
gathering gloom.

But neither the president nor the secretary of the Weldon Institute
noticed the strange modification in the landscape of Fairmount Park;
and neither did Frycollin. It seemed to him that the thieves were
approaching, and preparing for their attack; and he was seized with
convulsive fear, paralyzed in his limbs, with every hair he could
boast of on the bristle. His terror was extreme. His knees bent under
him, but he had just strength enough to exclaim for. the last time,
"Master Uncle! Master Uncle!"

"What is the matter with you?" asked Uncle Prudent.

Perhaps the disputants would not have been sorry to have relieved
their fury at the expense qf the unfortunate valet. But they had no
time; and neither even had he time to answer.

A whistle was heard. A flash of electric light shot across the
clearing.

A signal, doubtless? The moment had come for the deed of violence. In
less time that it takes to tell, six men came leaping across from
under the trees, two onto Uncle Prudent, two onto Phil Evans, two
onto Frycollin - there was no need for the last two, for the Negro
was incapable of defending himself. The president and secretary of
the Weldon Institute, athough taken by surprise, would have resisted.

They had neither time nor strength to do so. In a second they were
rendered speechless by a gag, blind by a bandage, thrown down,
pinioned and carried bodily off across the clearing. What could they
think except that they had fallen into the hands of people who
intended to rob them? The people did nothing of the sort, however.
They did not even touch Uncle Prudent's pockets, although, according
to his custom, they were full of paper dollars.

Within a minute of the attack, without a word being passed, Uncle
Prudent, Phil Evans, and Frycollin felt themselves laid gently down,
not on the grass, but on a sort of plank that creaked beneath them.
They were laid down side by side.

A door was shut; and the grating of a bolt in a staple told them that
they were prisoners.

Then there came a continuous buzzing, a quivering, a frrrr, with the
rrr unending.

And that was the only sound that broke the quiet of the night.

Great was the excitement next morning in Philadelphia Very early was
it known what had passed at the meeting of the Institute. Everyone
knew of the appearance of the mysterious engineer named Robur - Robur
the Conqueror - and the tumult among the balloonists, and his
inexplicable disappearance. But it was quite another thing when all
the town heard that the president and secretary of the club had also
disappeared during the night.

Long and keen was the search in the city and neighborhood! Useless!
The newspapers of Philadelphia, the newspapers of Pennsylvania, the
newspapers of the United States reported the facts and explained them
in a hundred ways, not one of which was the right one. Heavy rewards
were offered, and placards were pasted up, but all to no purpose. The
earth seemed to have opened and bodily swallowed the president and
secretary of the Weldon Institute.

Chapter VI

THE PRESIDENT AND SECRETARY SUSPEND HOSTILITIES

A bandage over the eyes, a gag in the mouth, a cord round the wrists,
a cord round the ankles, unable to see, to speak, or to move, Uncle
Prudent, Phil Evans, and Frycollin were anything but pleased with
their position. Knowing not who had seized them, nor in what they had
been thrown like parcels in a goods wagon, nor where they were, nor
what was reserved for them - it was enough to exasperate even the
most patient of the ovine race, and we know that the members of the
Weldon Institute were not precisely sheep as far as patience went.
With his violence of character we can easily imagine how Uncle
Prudent felt. One thing was evident, that Phil Evans and he would
find it difficult to attend the club next evening.

As to Frycollin, with his eyes shut and his mouth closed, it was
impossible for him to think of anything. He was more dead than alive.

For an hour the position of the prisoners remained unchanged. No one
came to visit, them, or to give them that liberty of movement and
speech of which they lay in such need. They were reduced to stiffled
sighs, to grunts emitted over and under their gags, to everything
that betrayed anger kept dumb and fury imprisoned, or rather bound
down. Then after many fruitless efforts they remained for some time
as though lifeless. Then as the sense of sight was denied them they
tried by their sense of hearing to obtain some indication of the
nature of this disquieting state of things. But in vain did they seek
for any other sound than an interminable and inexplicable f-r-r-r
which seemed to envelop them in a quivering atmosphere.

At last something happened. Phil Evans, regaining his coolness,
managed to slacken the cord which bound his wrists. Little by little
the knot slipped, his fingers slipped over each other, and his hands
regained their usual freedom.

A vigorous rubbing restored the circulation. A moment after he had
slipped off the bandage which bound his eyes, taken the gag out of
his mouth, and cut the cords round his ankles with his knife. An
American who has not a bowie-knife in his pocket is no longer an
American.

But if Phil Evans had regained the power of moving and speaking, that
was all. His eyes were useless to him - at present at any rate. The
prison was quite dark, though about six feet above him a feeble gleam
of light came in through a kind of loophole.

As may be imagined, Phil Evans did not hesitate to at once set free
his rival. A few cuts with the bowie settled the knots which bound
him foot and hand.

Immediately Uncle Prudent rose to his knees and snatched away his
bandage and gag.

"Thanks," said he, in stifled voice.

"Phil Evans?"

"Uncle Prudent?"

"Here we are no longer the president and secretary of the Weldon
Institute. We are adversaries no more."

"You are right," answered Evans. "We are now only two men agreed to
avenge ourselves on a third whose attempt deserves severe reprisals.
And this third is -"

"Robur!"

"It is Robur!"

On this point both were absolutely in accord. On this subject there
was no fear of dispute.

"And your servant?" said Phil Evans, pointing to Frycollin, who was
puffing like a grampus. "We must set him free."

"Not yet," said Uncle Prudent. "He would overwhelm us with his
jeremiads, and we have something else to do than abuse each other."

"What is that, Uncle Prudent?"

"To save ourselves if possible."

"You are right, even if it is impossible."

"And even if it is impossible."

There could be no doubt that this kidnapping was due to Robur, for an
ordinary thief would have relieved them of their watches, jewelry,
and purses, and thrown their bodies into the Schuyllkill with a good
gash in their throats instead of throwing them to the bottom of - Of
what? That was a serious question, which would have to be answered
before attempting an escape with any chance of success.

"Phil Evans," began Uncle Prudent, "if, when we came away from our
meeting, instead of indulging in amenities to which we need not
recur, we had kept our eyes more open, this would not have happened.
Had we remained in the streets of Philadelphia there would have been
none of this. Evidently Robur foresaw what would happen at the club,
and had placed some of his bandits on guard at the door. When we left
Walnut Street these fellows must have watched us and followed us, and
when we imprudently ventured into Fairmount Park they went in for
their little game."

"Agreed," said Evans. "We were wrong not to go straight home."

"It is always wrong not to be right," said Prudent.

Here a long-drawn sigh escaped from the darkest corner of the prison.
"What is that?" asked Evans.

"Nothing! Frycollin is dreaming."

"Between the moment we were seized a few steps out into the clearing
and the moment we were thrown in here only two minutes elapsed. It is
thus evident that those people did not take us out of Fairmount Park."

"And if they had done so we should have felt we were being moved."

"Undoubtedly; and consequently we must be in some vehicle, perhaps
some of those long prairie wagons, or some show-caravan -"

"Evidently! For if we were in a boat moored on the Schuyllkill we
should have noticed the movement due to the current -"

"That is so; and as we are still in the clearing, I think that now is
the time to get away, and we can return later to settle with this
Robur -"

"And make him pay for this attempt on the liberty of two citizens of
the United States."

"And he shall pay pretty dearly!"

"But who is this man? Where does he come from? Is he English, or
German, or French -"

"He is a scoundrel, that is enough!" said Uncle Prudent. "Now to
work." And then the two men, with their hands stretched out and their
fingers wide apart, began to feel round the walls to find a joint or
crack.

Nothing. Nothing; not even at the door. It was closely shut and it
was impossible to shoot back the lock. All that could be done was to
make a hole, and escape through the hole. It remained to be seen if
the knives could cut into the walls.

"But whence comes this never-ending rustling?" asked Evans, who was
much impressed at the continuous f-r-r-r.

"The wind, doubtless," said Uncle Prudent.

"The wind! But I thought the night was quite calm."

"So it was. But if it isn't the wind, what can it be?"

Phil Evans got out the best blade of his knife and set to work on the
wall near the door. Perhaps he might make a hole which would enable
him to open it from the outside should it be only bolted or should
the key have been left in the lock. He worked away for some minutes.
The only result was to nip up his knife, to snip off its point, and
transform what was left of the blade into a saw.

"Doesn't it cut?" asked Uncle Prudent.

"No."

"Is the wall made of sheet iron?"

"No; it gives no metallic sound when you hit it."

"Is it of ironwood?"

"No; it isn't iron and it isn't wood."

"What is it then?"

"Impossible to say. But, anyhow, steel doesn't touch it." Uncle
Prudent, in a sudden outburst of fury, began to rave and stamp on the
sonorous planks, while his hands sought to strangle an imaginary
Robur.

"Be calm, Prudent, he calm! You have a try."

Uncle Prudent had a try, but the bowie-knife could do nothing against
a wall which its best blades could not even scratch. The wall seemed
to be made of crystal.

So it became evident that all flight was impracticable except through
the door, and for a time they must resign themselves to their fate -
not a very pleasant thing for the Yankee temperament, and very much
to the disgust of these eminently practical men. But this conclusion
was not arrived at without many objurgations and loud-sounding
phrases hurled at this Robur - who, from what had been seen of him at
the Weldon Institute, was not the sort of man to trouble himself much
about them.

Suddenly Frycollin began to give unequivocal signs of being unwell.
He began to writhe in a most lamentable fashion, either with cramp in
his stomach or in his limbs; and Uncle Prudent, thinking it his duty
to put an end to these gymnastics, cut the cords that bound him.

He had cause to be sorry for it. Immediately there was poured forth
an interminable litany, in which the terrors of fear were mingled
with the tortures of hunger. Frycollin was no worse in his brain than
in his stomach, and it would have been difficult to decide to which
organ the chief cause of the trouble should be assigned.

"Frycollin!" said Uncle Prudent.

"Master Uncle! Master Uncle!" answered the Negro between two of his
lugubrious howls.

"It is possible that we are doomed to die of hunger in this prison,
but we have made up our minds not to succumb until we have availed
ourselves of every means of alimentation to prolong our lives,"

"To eat me?" exclaimed Frycollin.

"As is always done with a Negro under such circumstances! So you had
better not make yourself too obvious -"

"Or you'll have your bones picked!" said Evans.

And as Frycollin saw he might be used to prolong two existences more
precious than his own, he contented himself thenceforth with groaning
in quiet.

The time went on and all attempts to force the door or get through
the wall proved fruitless. What the wall was made of was impossible
to say. It was not metal; it was not wood; it was not stone, And all
the cell seemed to be made of the same stuff. When they stamped on
the floor it gave a peculiar sound that Uncle Prudent found it
difficult to describe; the floor seemed to sound hollow, as if it was
not resting directly on the ground of the clearing. And the
inexplicable f-r-r-r-r seemed to sweep along below it. All of which
was rather alarming.

"Uncle Prudent," said Phil Evans.

"Well?"

"Do you think our prison has been moved at all?"

"Not that I know of."

"Because when we were first caught I distinctly remember the fresh
fragrance of the grass and the resinous odor of the park trees. While
now, when I take in a good sniff of the air, it seems as though all
that had gone."

"So it has."

"Why?"

"We cannot say why unless we admit that the prison has moved; and I
say again that if the prison had moved, either as a vehicle on the
road or a boat on the stream, we should have felt it."

Here Frycollin gave vent to a long groan, which might have been taken
for his last bad he not followed it up with several more.

"I expect Robur will soon have us brought before him," said Phil
Evans.

"I hope so," said Uncle Prudent. "And I shall tell him -"

"What?"

"That he began by being rude and ended in being unbearable."

Here Phil Evans noticed that day was beginning to break. A gleam,
still faint, filtered through the narrow window opposite the door. It
ought thus to be about four o'clock in the morning for it is at that
hour in the month of June in this latitude that the horizon of
Philadelphia is tinged by the first rays of the dawn.

But when Uncle Prudent sounded his repeater - which was a masterpiece
from his colleague's factory - the tiny gong only gave a quarter to
three, and the watch had not stopped.

"That is strange!" said Phil Evans. "At a quarter to three it ought
still to be night".

"Perhaps my watch has got slow," answered Uncle Prudent.

"A watch of the Wheelton Watch Company!" exclaimed Phil Evans.

Whatever might be the reason, there was no doubt that the day was
breaking. Gradually the window became white in the deep darkness of
the cell. However, if the dawn appeared sooner than the fortieth
parallel permitted, it did not advance with the rapidity peculiar to
lower latitudes. This was another observation - of Uncle Prudent's -
a new inexplicable phenomenon.

"Couldn't we get up to the window and see where we are?"

"We might," said Uncle Prudent. "Frycollin, get up!"

The Negro arose.

"Put your back against the wall," continued Prudent, "and you, Evans,
get on his shoulders while I buttress him up."

"Right!" said Evans.

An instant afterwards his knees were on Frycollin's shoulders, and
his eyes were level with the window. The window was not of lenticular
glass like those on shipboard, but was a simple flat pane. It was
small, and Phil Evans found his range of view was much limited.

"Break the glass," said Prudent, "and perhaps you will be able to see
better."

Phil Evans gave it a sharp knock with the handle of his bowie-knife.
It gave back a silvery sound, but it did not break.

Another and more violent blow. The same result.

"It is unbreakable glass!" said Evans.

It appeared as though the pane was made of glass toughened on the
Siemens system - as after several blows it remained intact.

The light had now increased, and Phil Evans could see for some
distance within the radius allowed by the frame.

"What do you see?" asked Uncle Prudent.

"Nothing."

"What? Not any trees?"

"No."

"Not even the top branches?"

"No."

"Then we are not in the clearing?:

"Neither in the clearing nor in the park."

"Don't you see any roofs of houses or monuments?" said Prudent, whose
disappointment and anger were increasing rapidly.

"No."

"What! Not a flagstaff, nor a church tower, nor a chimney?"

"Nothing but space."

As he uttered the words the door opened. A man appeared on the
threshold. It was Robur.

"Honorable balloonists" he said, in a serious voice, "you are now
free to go and come as you like."

"Free!" exclaimed Uncle Prudent.

"Yes - within the limits of the _Albatross!_"

Uncle Prudent and Phil Evans rushed out of their prison. And what did
they see?

Four thousand feet below them the face of a country they sought in
vain to recognize.

Chapter VII

ON BOARD THE ALBATROSS

"When will man cease to crawl in the depths to live in the azure and
quiet of the sky?"

To this question of Camille Flammarion's the answer is easy. It will
be when the progress of mechanics has enabled us to solve the problem
of aviation. And in a few years - as we can foresee - a more
practical utilization of electricity will do much towards that
solution.

In 1783, before the Montgolfier brothers had built their
fire-balloon, and Charles, the physician, had devised his first
aerostat, a few adventurous spirits had dreamt of the conquest of
space by mechanical means. The first inventors did not think of
apparatus lighter than air, for that the science of their time did
not allow them to imagine. It was to contrivances heavier than air,
to flying machines in imitation of the birds, that they trusted to
realize aerial locomotion.

This was exactly what had been done by that madman Icarus, the son of
Daedalus, whose wings, fixed together with wax, had melted as they
approached the sun.

But without going back to mythological times, without dwelling on
Archytas of Tarentum, we find,in the works of Dante of Perugia, of
Leonardo da Vinci and Guidotti, the idea of machines made to move
through the air. Two centuries and a half afterwards inventors began
to multiply. In 1742 the Marquis de Bacqueville designed a system of
wings, tried it over the Seine, and fell and broke his arm. In 1768
Paucton conceived the idea of an apparatus with two screws,
suspensive and propulsive. In 1781 Meerwein, the architect of the
Prince of Baden, built an orthopteric machine, and protested against
the tendency of the aerostats which had just been invented. In 1784
Launoy and Bienvenu had maneuvered a helicopter worked by springs. In
1808 there were the attempts at flight by the Austrian Jacques Degen.
In 1810 came the pamphlet by Denian of Nantes, in which the
principles of "heavier than air" are laid down. From 1811 to 1840
came the inventions and researches of Derblinger, Vigual, Sarti,
Dubochet, and Cagniard de Latour. In 1842 we have the Englishman
Henson, with his system of inclined planes and screws worked by
steam. In 1845 came Cossus and his ascensional screws. In 1847 came
Camille Vert and his helicopter made of birds' wings. in 1852 came
Letur with his system of guidable parachutes, whose trial cost him
his life; and in the same year came Michel Loup with his plan of
gliding through the air on four revolving wings. In 1853 came
Bйlйguic and his aeroplane with the traction screws,
Vaussin-Chardannes with his guidable kite, and George Cauley with his
flying machines driven by gas. From 1854 to 1863 appeared Joseph
Pline with several patents for aerial systems. Brйant, Carlingford,
Le Bris, Du Temple, Bright, whose ascensional screws were
left-handed; Smythies, Panafieu, Crosnier, &c. At length, in 1863,
thanks to the efforts of Nadar, a society of "heavier than air" was
founded in Paris. There the inventors could experiment with the
machines, of which many were patented. Ponton d'Amйcourt and his
steam helicopter, La Landelle and his system of combining screws with
inclined planes and parachutes, Louvriй and his aeroscape, Esterno
and his mechanical bird, Groof and his apparatus with wings worked by
levers. The impetus was given, inventors invented, calculators
calculated all that could render aerial locomotion practicable.
Bourcart, Le Bris, Kaufmann, Smyth, Stringfellow, Prigent, Danjard,
Pomйs and De la Pauze, Moy, Pйnaud, Jobert Haureau de Villeneuve,
Achenbach, Garapon, Duchesne, Danduran, Pariesel, Dieuaide,
Melkiseff, Forlanini, Bearey, Tatin, Dandrieux, Edison, some with
wings or screws, others with inclined planes, imagined, created,
constructed, perfected, their flying machines, ready to do their
work, once there came to be applied to thereby some inventor a motor
of adequate power and excessive lightness.

This list may be a little long, but that will be forgiven, for it is
necessary to give the various steps in the ladder of aerial
locomotion, on the top of which appeared Robur the Conqueror. Without
these attempts, these experiments of his predecessors, how could the
inquirer have conceived so perfect an apparatus? And though he had
but contempt for those who obstinately worked away in the direction
of balloons, he held in high esteem all those partisans of "heavier
than air," English, American, Italian, Austrian, French - and
particularly French - whose work bad been perfected by him, and led
him to design and then to build this flying engine known as the
_Albatross,_ which he was guiding through the currents of the
atmosphere.

"The pigeon flies!" had exclaimed one of the most persistent adepts
at aviation.

"They will crowd the air as they crowd the earth!" said one of his
most excited partisans.

"From the locomotive to the aeromotive!" shouted the noisiest of all,
who had turned on the trumpet of publicity to awaken the Old and New
Worlds.

Nothing, in fact, is better established, by experiment and
calculation, than that the air is highly resistant. A circumference
of only a yard in diameter in the shape of a parachute can not only
impede descent in air, but can render it isochronous. That is a fact.

It is equally well known that when the speed is great the work of the
weight varies in almost inverse ratio to the square of the speed, and
therefore becomes almost insignificant.

It is also known that as the weight of a flying animal increases, the
less is the proportional increase in the surface beaten by the wings
in order to sustain it, although the motion of the wings becomes
slower.

A flying machine must therefore be constructed to take advantage of
these natural laws, to imitate the bird, "that admirable type of
aerial locomotion," according to Dr. Marcy, of the Institute of
France.

In short the contrivances likely to solve the problem are of three
kinds: -

1. Helicopters or spiralifers, which are simply screws with vertical
axes.

2. Ornithopters, machines which endeavour to reproduce the natural
flight of birds.

3. Aeroplanes, which are merely inclined planes like kites, but towed
or driven by screws.

Each of these systems has had and still has it partisans obstinately
resolved to give way in not the slighest particular. However, Robur,
for many reasons, had rejected the two first.

The ornithopter, or mechanical bird, offers certain advantages, no
doubt. That the work and experiments of M. Renard in 1884 have
sufficiently proved. But, as has been said, it is not necessary to
copy Nature servilely. Locomotives are not copied from the hare, nor
are ships copied from the fish. To the first we have put wheels which
are not legs; to the second we have put screws which are not fins.
And they do not do so badly. Besides, what is this mechanical
movement in the flight of birds, whose action is so complex? Has not
Doctor Marcy suspected that the feathers open during the return of
the wings so as to let the air through them? And is not that rather a
difficult operation for an artificial machine?

On the other hand, aeroplanes have given many good results. Screws
opposing a slanting plane to the bed of air will produce an
ascensional movement, and the models experimented on have shown that
the disposable weight, that is to say the weight it is possible to
deal with as distinct from that of the apparatus, increases with the
square of the speed. Herein the aeroplane has the advantage over the
aerostat even when the aerostat is furnished with the means of
locomotion.

Nevertheless Robur had thought that the simpler his contrivance the
better. And the screws - the Saint Helices that had been thrown in
his teeth at the Weldon Institute - had sufficed for all the needs of
his flying machine. One series could hold it suspended in the air,
the other could drive it along under conditions that were marvelously
adapted for speed and safety.

If the ornithopter - striking like the wings of a bird - raised
itself by beating the air, the helicopter raised itself by striking
the air obliquely, with the fins of the screw as it mounted on an
inclined plane. These fins, or arms, are in reality wings, but wings
disposed as a helix instead of as a paddle wheel. The helix advances
in the direction of its axis. Is the axis vertical? Then it moves
vertically. Is the axis horizontal? Then it moves horizontally.

The whole of Robur's flying apparatus depended on these two
movements, as will be seen from the following detailed description,
which can be divided under three heads - the platform, the engines of
suspension and propulsion, and the machinery.

Platform.- This was a framework a hundred feet long and twelve wide,
a ship's deck in fact, with a projecting prow. Beneath was a hull
solidly built, enclosing the engines, stores, and provisions of all
sorts, including the watertanks. Round the deck a few light uprights
supported a wire trellis that did duty for bulwarks. On the deck were
three houses, whose compartments were used as cabins for the crew, or
as machine rooms. In the center house was the machine which drove the
suspensory helices, in that forward was the machine that drove the
bow screw, in that aft was the machine that drove the stern screw. In
the bow were the cook's galley and the crew's quarters; in the stern
were several cabins, including that of the engineer, the saloon, and
above them all a glass house in which stood the helmsman, who steered
the vessel by means of a powerful rudder. All these cabins were
lighted by port-holes filled with toughened glass, which has ten
times the resistance of ordinary glass. Beneath the hull was a system
of flexible springs to ease off the concussion when it became
advisable to land.

Engines of suspension and propulsion.- Above the deck rose
thirty-seven vertical axes, fifteen along each side, and seven, more
elevated, in the centre. The _Albatross_ might be called a clipper
with thirty-seven masts. But these masts instead of sails bore each
two horizontal screws, not very large in spread or diameter, but
driven at prodigious speed. Each of these axes had its own movement
independent of the rest, and each alternate one spun round in a
different direction from the others, so as to avoid any tendency to
gyration. Hence the screws as they rose on the vertical column of air
retained their equilibrium by their horizontal resistance.
Consequently the apparatus was furnished with seventy-four suspensory
screws, whose three branches were connected by a metallic circle
which economized their motive force. In front and behind, mounted on
horizontal axes, were two propelling screws, each with four arms.
These screws were of much larger diameter than the suspensory ones,
but could be worked at quite their speed. In fact, the vessel
combined the systems of Cossus, La LandeNe, and Ponton d'Amйcourt, as
perfected by Robur. But it was in the choice and application of his
motive force that he could claim to be an inventor.

Machinery.- Robur had not availed himself of the vapor of water or
other liquids, nor compressed air and other mechanical motion. He
employed electricity, that agent which one day will be the soul of
the industrial world. But he required no electro-motor to produce it.
All he trusted to was piles and accumulators. What were the elements
of these piles, and what were the acids he used, Robur only knew. And
the construction of the accumulators was kept equally secret. Of what
were their positive and negative plates? None can say. The engineer
took good care - and not unreasonably - to keep his secret
unpatented. One thing was unmistakable, and that was that the piles
were of extraordinary strength; and the accumulators left those of
Faure-Sellon-Volckmar very far behind in yielding currents whose
ampиres ran into figures up to then unknown. Thus there was obtained
a power to drive the screws and communicate a suspending and
propelling force in excess of all his requirements under any
circumstances.

But - it is as well to repeat it - this belonged entirely to Robur.
He kept it a close secret. And, if the president and secretary of the
Weldon Institute did not happen to discover it, it would probably be
lost to humanity.

It need not be shown that the apparatus possessed sufficient
stability. Its center of gravity proved that at once. There was no
danger of its making alarming angles with the horizontal, still less
of its capsizing.

And now for the metal used by Robur in the construction of his
aeronef - a name which can be exactly applied to the _Albatross._
What was this material, so hard that the bowie-knife of Phil Evans
could not scratch it, and Uncle Prudent could not explain its nature?
Simply paper!

For some years this fabrication had been making considerable
progress. Unsized paper, with the sheets impregnated with dextrin and
starch and squeezed in hydraulic presses, will form a material as
hard as steel. There are made of it pulleys, rails, and wagon-wheels,
much more solid than metal wheels, and far lighter. And it was this
lightness and solidity which Robur availed himself of in building his
aerial locomotive. Everything - framework, hull, houses, cabins -
were made of straw-paper turned hard as metal by compression, and -
what was not to be despised in an apparatus flying at great heights -
incombustible. The different parts of the engines and the screws were
made of gelatinized fiber, which combined in sufficient degree
flexibility with resistance. This material could be used in every
form. It was insoluble in most gases. and liquids, acids or essences,
to say nothing of its insulating properties, and it proved most
valuable in the electric machinery of the _Albatross._

Robur, his mate Tom Turner, an engineer and two assistants, two
steersman and a cook - eight men all told - formed the crew of the
aeronef, and proved ample for all the maneuvers required in aerial
navigation. There were arms of the chase and of war; fishing
appliances; electric lights; instruments of observation, compasses,
and sextants for checking the course, thermometers for studying the
temperature, different barometers, some for estimating the heights
attained, others for indicating the variations of atmospheric
pressure; a storm-glass for forecasting tempests; a small library; a
portable printing press; a field-piece mounted on a pivot; breech
loading and throwing a three-inch shell; a supply of powder, bullets,
dynamite cartridges; a cooking-stove, warmed by currents from the
accumulators; a stock of preserves, meats and vegetables sufficient
to last for months. Such were the outfit and stores of the aeronef -
in addition to the famous trumpet.

There was besides a light india-rubber boat, insubmersible, which
could carry eight men on the surface of a river, a lake, or a calm
sea.

But were there an parachutes in case of accident? No. Robur did not
believe in accidents of that kind. The axes of the screws were
independent. The stoppage of a few would not affect the motion of the
others; and if only half were working, the _Albatross_ could still
keep afloat in her natural element.

"And with her," said Robur to his guests - guests in spite of
themselves - "I am master of the seventh part of the world, larger
than Africa, Oceania, Asia, America, and Europe, this aerial Icarian
sea, which millions of lcarians will one day people."

- Chapter VIII

THE BALLOONISTS REFUSE TO BE CONVINCED

The President of the Weldon Institute was stupefied; his companion
was astonished. But neither of them would allow any of their very
natural amazement to be visible.

The valet Frycollin did not conceal his terror at finding himself
borne through space on such a machine, and he took no pains whatever
to hide it.

The suspensory screws were rapidly spinning overhead. Fast as they
were going, they would have to triple their speed if the _Albatross_
was to ascend to higher zones. The two propellers were running very
easily and driving the ship at about eleven knots an hour.

As they leaned over the rail the passengers of the _Albatross_ could
perceive a long sinuous liquid ribbon which meandered like a mere
brook through a varied country amid the gleaming of many lagoons
obliquely struck by the rays of the sun. The brook was a river, one
of the most important in that district. Along its left bank was a
chain of mountains extending out of sight.

"And will you tell us where we are?" asked Uncle Prudent, in a voice
tremulous with anger.

"I have nothing to teach you," answered Robur.

"And will you tell us where we are going?" asked Phil Evans.

"Through space."

"And how long will that last?"

"Until it ends."

"Are we going round the world?" asked Phil Evans ironically.

"Further than that," said Robur.

"And if this voyage does not suit us?" asked Uncle Prudent.

"It will have to suit you."

That is a foretaste of the nature of the relations that were to
obtain between the master of the _Albatross_ and his guests, not to
say his prisoners. Manifestly he wished to give them time to cool
down, to admire the marvelous apparatus which was bearing them
through the air, and doubtless to compliment the inventor. And so he
went off to the other end of the deck, leaving them to examine the
arrangement of the machinery and the management of the ship or to
give their whole attention to the landscape which was unrolling
beneath them.

"Uncle Prudent," said Evans, "unless I am mistaken we are flying over
Central Canada. That river in the northwest is the St. Lawrence. That
town we are leaving behind is Quebec."

It was indeed the old city of Champlain, whose zinc roofs were
shining like reflectors in the sun. The _Albatross_ must thus have
reached the forty-sixth degree of north latitude, and thus was
explained the premature advance of the day with the abnormal
prolongation of the dawn.

"Yes," said Phil Evans, "There is the town in its amphitheater, the
hill with its citadel, the Gibralter of North America. There are the
cathedrals. There is the Custom House with its dome surmounted by the
British flag!"

Phil Evans had not finished before the Canadian city began to slip
into the distance.

The clipper entered a zone of light clouds, which gradually shut off
a view of the ground.

Robur, seeing that the president and secretary of the Weldon
Institute had directed their attention to the external arrangements
of the _Albatross,_ walked up to them and said: "Well, gentlemen, do
you believe in the possibility of aerial locomotion by machines
heavier than air?"

It would have been difficult not to succumb to the evidence. But
Uncle Prudent and Phil Evans did not reply.

"You are silent," continued the engineer. "Doubtless hunger makes you
dumb! But if I undertook to carry you through the air, I did not
think of feeding you on such a poorly nutritive fluid. Your first
breakfast is waiting for you."

As Uncle Prudent and Phil Evans were feeling the pangs of hunger
somewhat keenly they did not care to stand upon ceremony, A meal
would commit them to nothing; and when Robur put them back on the
ground they could resume full liberty of action.

And so they followed into a small dining-room in the aftermost house.
There they found a well-laid table at which they could take their
meals during the voyage. There were different preserves; and, among
other things, was a sort of bread made of equal parts of flour and
meat reduced to powder and worked together with a little lard, which
boiled in water made excellent soup; and there were rashers of fried
ham, and for drink there was tea.

Neither had Frycollin been forgotten. He was taken forward and there
found some strong soup made of this bread. In truth he had to be very
hungry to eat at all, for his jaws shook with fear, and almost
refused to work. "If it was to break! If it was to break!" said the
unfortunate Negro. Hence continual faintings. Only think! A fall of
over four thousand feet, which would smash him to a jelly!

An hour afterwards Uncle Prudent and Phil Evans appeared on the deck.
Robur was no longer there. At the stem the man at the wheel in his
glass cage, his eyes fixed on the compass, followed imperturbably
without hesitation the route given by the engineer.

As for the rest of the crew, breakfast probably kept them from their
posts. An assistant engineer, examining the machinery, went from one
h6use to the other.

If the speed of the ship was great the two colleagues could only
estimate it imperfectly, for the _Albatross_ had passed through the
cloud zone which the sun showed some four thousand feet below.

"I can hardly believe it," said Phil Evans.

"Don't believe it!" said Uncle Prudent. And going to the bow they
looked out towards the western horizon.

"Another town," said Phil Evans.

"Do you recognize it?"

"Yes! It seems to me to be Montreal."

"Montreal? But we only left Quebec two hours ago!"

"That proves that we must be going at a speed of seventy-five miles
an hour."

Such was the speed of the aeronef; and if the passengers were not
inconvenienced by it, it was because they were going with the wind.
In a calm such speed would have been difficult and the rate would
have sunk to that of an express. In a head-wind the speed would have
been unbearable.

Phil Evans was not mistaken. Below the _Albatross_ appeared Montreal,
easily recognizable by the Victoria Bridge, a tubular bridge thrown
over the St. Lawrence like the railway viaduct over the Venice
lagoon. Soon they could distinguish the town's wide streets, its huge
shops, its palatial banks, its cathedral, recently built on the model
of St. Peter's at Rome, and then Mount Royal, which commands the city
and forms a magnificent park.

Luckily Phil Evans had visited the chief towns of Canada, and could
recognize them without asking Robur. After Montreal they passed
Ottawa, whose falls, seen from above, looked like a vast cauldron in
ebullition, throwing off masses of steam with grand effect.

"There is the Parliament House."

And he pointed out a sort of Nuremburg toy planted on a hill top.
This toy with its polychrome architecture resembled the House of
Parliament in London much as the Montreal cathedral resembles St.
Peter's at Rome. But that was of no consequence; there could be no
doubt it was Ottawa.

Soon the city faded off towards the horizon, and formed but a
luminous spot on the ground.

It was almost two hours before Robur appeared. His mate, Tom Turner,
accompanied him. He said only three words. These were transmitted to
the two assistant engineers in the fore and aft engine-houses. At a
sign the helmsman changed the-direction of the _Albatross_ a couple
of points to the southwest; at the same time Uncle Prudent and Phil
Evans felt that a greater speed had been given to the propellers.

In fact, the speed bad been doubled, and now surpassed anything that
had ever been attained by terrestrial Engines. Torpedo-boats do their
twenty-two knots an hour; railway trains do their sixty miles an
hour; the ice-boats on the frozen Hudson do their sixty-five miles an
hour; a machine built by the Patterson company, with a cogged wheel,
has done its eighty miles; and another locomotive between Trenton and
Jersey City has done its eighty-four.

But the _Albatross,_ at full speed, could do her hundred and twenty
miles an hour, or 176 feet per second. This speed is that of the
storm which tears up trees by the roots. It is the mean speed of the
carrier pigeon, and is only surpassed by the flight of the swallow
(220 feet per second) and that of the swift (274 feet per second).

In a word, as Robur had said, the _Albatross,_ by using the whole
force of her screws, could make the tour of the globe in two hundred
hours, or less than eight days.

Is it necessary to say so? The phenomenon whose appearance had so
much puzzled the people of both worlds was the aeronef of the
engineer. The trumpet which blared its startling fanfares through the
air was that of the mate, Tom Turner. The flag planted on the chief
monuments of Europe, Asia, America, was the flag of Robur the
Conqueror and his _Albatross._

And if up to then the engineer had taken many precautions against
being recognized, if by preference he traveled at night, clearing the
way with his electric lights, and during the day vanishing into the
zones above the clouds, he seemed now to have no wish to keep his
secret hidden. And if he had come to Philadelphia and presented
himself at the meeting of the Weldon Institute, was it not that they
might share in his prodigious discovery, and convince _ipso facto_
the most incredulous? We know how he had been received, and we see
what reprisals he had taken on the president and secretary of the
club.

Again did Robur approach his prisoners, who affected to be in no way
surprised at what they saw, of what had succeeded in spite of them.
Evidently beneath the cranium of these two Anglo-Saxon heads there
was a thick crust of obstinacy, which would not be easy to remove.

On his part, Robur did not seem to notice anything particular, and
coolly continued the conversation which he had begun two hours before.

"Gentlemen," said he, "you ask yourselves doubtless if this
apparatus, so marvelously adapted for aerial locomotion, is
susceptible of receiving greater speed. It is not worth while to
conquer space if we cannot devour it. I wanted the air to be a solid
support to me, and it is. I saw that to struggle against the wind I
must be stronger than the wind, and I am. I had no need of sails to
drive me, nor oars nor wheels to push me, nor rails to give me a
faster road. Air is what I wanted, that was all. Air surrounds me as
it surrounds the submarine boat, and in it my propellers act like the
screws of a steamer. That is how I solved the problem of aviation.
That is what a balloon will never do, nor will any machine that is
lighter than air."

Silence, absolute, on the part of the colleagues, which did not for a
moment disconcert the engineer. He contented himself with a
half-smile, and continued in his interrogative style, "Perhaps you
ask if to this power of the _Albatross_ to move horizontally there is
added an equal power of vertical movement - in a word, if, when, we
visit the higher zones of the atmosphere, we can compete with an
aerostat? Well, I should not advise you to enter the _Go-Ahead_
against her!"

The two colleagues shrugged their shoulders. That was probably what
the engineer was waiting for.

Robur made a sign. The propelling screws immediately stopped, and
after running for a mile the _Albatross_ pulled up motionless.

At a second gesture from Robur the suspensory helices revolved at a
speed that can only be compared to that of a siren in acoustical
experiments. Their f-r-r-r-r rose nearly an octave in the scale of
sound, diminishing gradually in intensity as the air became more
rarified, and the machine rose vertically, like a lark singing his
song in space.

"Master! Master!" shouted Frycollin. "See that it doesn't break!"

A smile of disdain was Robur's only reply. In a few minutes the
_Albatross_ had attained the height of 8,700 feet, and extended the
range of vision by seventy miles, the barometer having fallen 480
millimeters.

Then the _Albatross_ descended. The diminution of the pressure in
high altitudes leads to the diminution of oxygen in the air, and
consequently in the blood. This has been the cause of several serious
accidents which have happened to aeronauts, and Robur saw no reason
to run any risk.

The _Albatross_ thus returned to the height she seemed to prefer, and
her propellers beginning again, drove her off to the southwest.

"Now, sirs, if that is what you wanted you can reply." Then, leaning
over the rail, he remained absorbed in contemplation.

When he raised his head the president and secretary of the Weldon
Institute stood by his side.

"Engineer Robur," said Uncle Prudent, in vain endeavoring to control
himself, "we have nothing to ask about what you seem to believe, but
we wish to ask you a question which we think you would do well to
answer."

"Speak."

"By what right did you attack us in Philadelphia in Fairmount Park?
By what right did you shut us up in that prison? By what right have
you brought us against our will on board this flying machine?"

"And by what right, Messieurs Balloonists, did you insult and
threaten me in your club in such a way that I am astonished I came
out of it alive?"

"To ask is not to answer," said Phil Evans, "and I repeat, by what
right?"

"Do you wish to know?"

"If you please."

"Well, by the right of the strongest!"

"That is cynical."

"But it is true."

"And for how long, citizen engineer," asked Uncle Prudent, who was
nearly exploding, "for how long do you intend to exercise that right?"

"How can you?" said Robur, ironically, "how can you ask me such a
question when you have only to cast down your eyes to enjoy a
spectacle unparalleled in the world?"

The _Albatross_ was then sweeping across the immense expanse of Lake
Ontario. She had just crossed the country so poetically described by
Cooper. Then she followed the southern shore and headed for the
celebrated river which pours into it the waters of Lake Erie,
breaking them to powder in its cataracts.

In an instant a majestic sound, a roar as of the tempest, mounted
towards them and, as if a humid fog had been projected into the air,
the atmosphere sensibly freshened. Below were the liquid masses. They
seemed like an enormous flowing sheet of crystal amid a thousand
rainbows due to refraction as it decomposed the solar rays. The sight
was sublime.

Before the falls a foot-bridge, stretching like a thread, united one
bank to the other. Three miles below was a suspension-bridge, across
which a train was crawling from the Canadian to the American bank.

"The falls of Niagara!" exclaimed Phil Evans. And as the exclamation
escaped him, Uncle Prudent was doing all could do to admire nothing
of these wonders.

A minute afterwards the _Albatross_ had crossed the river which
separates the United States from Canada, and was flying over the vast
territories of the West.

Chapter IX

ACROSS THE PRAIRIE

In one, of the cabins of the after-house Uncle Prudent and Phil Evans
had found two excellent berths, with clean linen, change of clothes,
and traveling-cloaks and rugs. No Atlantic liner could have offered
them more comfort. If they did not Sleep soundly it was that they did
not wish to do so, or rather that their very real anxiety prevented
them. In what adventure had they embarked? To what series of
experiments had they been invited? How would the business end? And
above all, what was Robur going to do with them?

Frycollin, the valet, was quartered forward in a cabin adjoining that
of the cook. The neighborhood did not displease him; he liked to rub
shoulders with the great in this world. But if he finally went to
sleep it was to dream of fall after fall, of projections through
space, which made his sleep a horrible nightmare.

However, nothing could be quieter than this journey through the
atmosphere, whose currents had grown weaker with the evening. Beyond
the rustling of the blades of the screws there was not a sound,
except now and then the whistle from some terrestrial locomotive, or
the calling of some animal. Strange instinct! These terrestrial
beings felt the aeronef glide over them, and uttered cries of terror
as it passed. On the morrow, the 14th of June, at five o'clock, Uncle
Prudent and Phil Evans were walking on the deck of the _Albatross._

Nothing had changed since the evening; there was a lookout forward,
and the helmsman was in his glass cage. Why was there a look-out? Was
there any chance of collision with another such machine? Certainly
not. Robur had not yet found imitators. The chance of encountering an
aerostat gliding through the air was too remote to be regarded. In
any case it would be all the worse for the aerostat - the earthen pot
and the iron pot. The _Albatross_ had nothing to fear from the
collision.

But what could happen? The aeronef might find herself like a ship on
a lee shore if a mountain that could not be outflanked or passed
barred the way. These are the reefs of the air, and they have to be
avoided as a ship avoids the reefs of the sea. The engineer, it is
true, had given the course, and in doing so had taken into account
the altitude necessary to clear the summits of the high lands in the
district. But as the aeronef was rapidly nearing a mountainous
country, it was only prudent to keep a good lookout, in case some
slight deviation from the course became necessary.

Looking at the country beneath them, Uncle Prudent and Phil Evans
noticed a large lake, whose lower southern end the _Albatross_ had
just reached. They concluded, therefore, that during the night the
whole length of Lake Erie had been traversed, and that, as they were
going due west, they would soon be over Lake Michigan. "There can be
no doubt of it," said Phil Evans, "and that group of roofs on the
horizon is Chicago."

He was right. It was indeed the city from which the seventeen
railways diverge, the Queen of the West, the vast reservoir into
which flow the products of Indiana, Ohio, Wisconsin, Missouri, and
all the States which form the western half of the Union.

Uncle Prudent, through an excellent telescope he had found in his
cabin, easily recognized the principal buildings. His colleague
pointed out to him the churches and public edifices, the numerous
"elevators" or mechanical, granaries, and the huge Sherman Hotel,
whose windows seemed like a hundred glittering points on each of its
faces.

"If that is Chicago," said Uncle Prudent, "it is obvious that we are
going farther west than is convenient for us if we are to return to
our starting-place."

And, in fact, the _Albatross_ was traveling in a straight line from
the Pennsylvania capital.

But if Uncle Prudent wished to ask Robur to take him eastwards he
could not then do so. That morning the engineer did not leave his
cabin. Either he was occupied in some work, or else he was asleep,
and the two colleagues sat down to breakfast without seeing him.

The speed was the same as that during last evening. The wind being
easterly the rate was not interfered with at all, and as the
thermometer only falls a degree centigrade for every seventy meters
of elevation the temperature was not insupportable. And so, in
chatting and thinking and waiting for the engineer, Uncle Prudent and
Phil Evans walked about beneath the forest of screws, whose gyratory
movement gave their arms the appearance of semi-diaphanous disks.

The State of Illinois was left by its northern frontier in less than
two hours and a half; and they crossed the Father of Waters, the
Mississippi, whose double-decked steam-boats seemed no bigger than
canoes. Then the _Albatross_ flew over Iowa after having sighted Iowa
City about eleven o'clock in the morning.

A few chains of hills, "bluffs" as they are called, curved across the
face of the country trending from the south to the northwest, whose
moderate height necessitated no rise in the course of the aeronef.
Soon the bluffs gave place to the large plains of western Iowa and
Nebraska - immense prairies extending all the way to the foot of the
Rocky Mountains. Here and there were many rios, affluents or minor
affluents of the Missouri. On their banks were towns and villages,
growing more scattered as the _Albatross_ sped farther west.

Nothing particular happened during this day. Uncle Prudent and Phil
Evans were left entirely to themselves. They hardly noticed Frycollin
sprawling at full length in the bow, keeping his eyes shut so that he
could see nothing. And they were not attacked by vertigo, as might
have been expected. There was no guiding mark, and there was nothing
to cause the vertigo, as there would have been on the top of a lofty
building. The abyss has no attractive power when it is gazed at from
the car of a balloon or deck of an aeronef. It is not an abyss that
opens beneath the aeronaut, but an horizon that rises round him on
all sides like a cup.

In a couple of hours the _Albatross_ was over Omaha, on the Nebraskan
frontier - Omaha City, the real head of the Pacific Railway, that
long line of rails, four thousand five hundred miles in length,
stretching from New York to San Francisco. For a moment they could
see the yellow waters of the Missouri, then the town, with its houses
of wood and brick in the center of a rich basin, like a buckle in the
iron belt which clasps North America round the waist. Doubtless,
also, as the passengers in the aeronef could observe all these
details, the inhabitants of Omaha noticed the strange machine. Their
astonishment at seeing it gliding overhead could be no greater than
that of the president and secretary of the Weldon Institute at
finding themselves on board.

Anyhow, the journals of the Union would be certain to notice the
fact. It would be the explanation of the astonishing phenomenon which
the whole world had been wondering over for some time.

In an hour the _Albatross_ had left Omaha and crossed the Platte
River, whose valley is followed by the Pacific Railway in its route
across the prairie. Things looked serious for Uncle Prudent and Phil
Evans.

"It is serious, then, this absurd project of taking us to the
Antipodes."

"And whether we like it or not!" exclaimed the other.

"Robur had better take care! I am not the man to stand that sort of
thing."

"Nor am I!" replied Phil Evans. "But be calm, Uncle Prudent, be calm."

"Be calm!"

"And keep your temper until it is wanted."

By five o'clock they had crossed the Black Mountains covered with
pines and cedars, and the _Albatross_ was over the appropriately
named Bad Lands of Nebraska - a chaos of ochre-colored hills, of
mountainous fragments fallen on the soil and broken in their fall. At
a distance these blocks take the most fantastic shapes. Here and
there amid this enormous game of knucklebones there could be traced
the imaginary ruins of medieval cities with forts and dungeons,
pepper-box turrets, and machicolated towers. And in truth these Bad
Lands are an immense ossuary where lie bleaching in the sun myriads
of fragments of pachyderms, chelonians, and even, some would have us
believe, fossil men, overwhelmed by unknown cataclysms ages and ages
ago.

When evening came the whole basin of the Platte River had been
crossed, and the plain extended.to the extreme limits of the horizon,
which rose high owing to the altitude of the _Albatross._

During the night there were no more shrill whistles of locomotives or
deeper notes of the river steamers to trouble the quiet of the starry
firmament. Long bellowing occasionally reached the aeronef from the
herds of buffalo that roamed over the prairie in search of water and
pasturage. And when they ceased, the trampling of the grass under
their feet produced a dull roaring similar to the rushing of a flood,
and very different from the continuous f-r-r-r-r of the screws.

Then from time to time came the howl of a wolf, a fox, a wild cat, or
a coyote, the _Canis latrans,_ whose name is justified by his
sonorous bark.

Occasionally came penetrating odors of mint, and sage, and absinthe,
mingled with the more powerful fragrance of the conifers which rose
floating. through the night air.

At last came a menacing yell, which was not due to the coyote. It was
the shout of a Redskin, which no Tenderfoot would confound with the
cry of a wild beast.

Chapter X

WESTWARD - BUT WHITHER?

The next day, the 15th of June, about five o'clock in the morning,
Phil Evans left his cabin. Perhaps he would today have a chance of
speaking to Robur? Desirous of knowing why he had not appeared the
day before, Evans addressed himself to the mate, Tom Turner.

Tom Turner was an Englishman of about forty-five, broad in the
shoulders and short in the legs, a man of iron, with one of those
enormous characteristic heads that Hogarth rejoiced in.

Shall we see Mr. Robur to-day?" asked Phil Evans.

"I don't know," said Turner.

"I need not ask if he has gone out."

"Perhaps he has."

"And when will he come back?"

"When he has finished his cruise."

And Tom went into his cabin.

With this reply they had to be contented. Matters did not look
promising, particularly as on reference to the compass it appeared
that the _Albatross_ was still steering southwest.

Great was the contrast between the barren tract of the Bad Lands
passed over during the night and the landscape then unrolling beneath
them.

The aeronef was now more than six hundred miles from Omaha, and over
a country which Phil Evans could not recognize because he had never
been there before. A few forts to keep the Indians in order crowned
the bluffs with their geometric lines, formed oftener of palisades
than walls. There were few villages, and few inhabitants, the country
differing widely from the auriferous lands of Colorado many leagues
to the south.

In the distance a long line of mountain crests, in great confusion as
yet, began to appear. They were the Rocky Mountains.

For the first time that morning Uncle Prudent and Phil Evans were
sensible of a certain lowness of temperature which was not due to a
change in the weather, for the sun shone in superb splender.

"It is because of the _Albatross_ being higher in the air," said Phil
Evans.

In fact the barometer outside the central deck-house had fallen 540
millimeters, thus indicating an elevation of about 10,000 feet above
the sea. The aeronef was at this altitude owing to the elevation of
the ground. An hour before she had been at a height of 13,000 feet,
and behind her were mountains covered with perpetual snow.

There was nothing Uncle Prudent and his companion could remember
which would lead them to discover where they were. During the night
the _Albatross_ had made several stretches north and south at
tremendous speed, and that was what had put them out of their
reckoning.

After talking over several hypotheses more or less plausible they
came to the conclusion that this country encircled with mountains
must be the district declared by an Act of Congress in March, 1872,
to be the National Park of the United States. A strange region it
was. It well merited the name of a park - a park with mountains for
hills, with lakes for ponds, with rivers for streamlets, and with
geysers of marvelous power instead of fountains.

In a few minutes the _Albatross_ glided across the Yellowstone River,
leaving Mount Stevenson on the right, and coasting the large lake
which bears the name of the stream. Great was the variety on the
banks of this basin, ribbed as they were with obsidian and tiny
crystals, reflecting the sunlight on their myriad facets. Wonderful
was the arrangement of the islands on its surface; magnificent were
the blue reflections of the gigantic mirror. And around the lake, one
of the highest in the globe, were multitudes of pelicans, swans,
gulls and geese, bernicles and divers. In places the steep banks were
clothed with green trees, pines and larches, and at the foot of the
escarpments there shot upwards innumerable white fumaroles, the vapor
escaping from the soil as from an enormous reservoir in which the
water is kept in permanent ebullition by subterranean fire.

The cook might have seized the opportunity of securing an ample
supply of trout, the only fish the Yellowstone Lake contains in
myriads. But the _Albatross_ kept on at such a height that there was
no chance of indulging in a catch which assuredly would have been
miraculous.

In three quarters of an hour the lake was overpassed, and a little
farther on the last was seen of the geyser region, which rivals the
finest in Iceland. Leaning over the rail, Uncle Prudent and Phil
Evans watched the liquid columns which leaped up as though to furnish
the aeronef with a new element. There were the Fan, with the jets
shot forth in rays, the Fortress, which seemed to be defended by
waterspouts, the Faithful Friend, with her plume crowned with the
rainbows, the Giant, spurting forth a vertical torrent twenty feet
round and more than two hundred feet high.

Robur must evidently have been familiar with this incomparable
spectacle, unique in the world, for he did not appear on deck. Was
it, then, for the sole pleasure of his guests that he had brought the
aeronef above the national domain? If so, he came not to receive
their thanks. He did not even trouble himself during the daring
passage of the Rocky Mountains, which the _Albatross_ approached at
about seven o'clock.

By increasing the speed of her wings, as a bird rising in its flight,
the _Albatross_ would clear the highest ridges of the chain, and sink
again over Oregon or Utah, But the maneuver was unnecessary. The
passes allowed the barrier to be crossed without ascending for the
higher ridges. There are many of these canyons, or steep valleys,
more or less narrow, through which they could glide, such as Bridger
Gap, through which runs the Pacific Railway into the Mormon
territory, and others to the north and south of it.

It was through one of these that the _Albatross_ headed, after
slackening speed so as not to dash against the walls of the canyon.
The steersman, with a sureness of hand rendered more effective by the
sensitiveness of the rudder, maneuvered his craft as if she were a
crack racer in a Royal Victoria match. It was really extraordinary.
In spite of all the jealousy of the two enemies of "lighter than
air," they could not help being surprised at the perfection of this
engine of aerial locomotion.

In less than two hours and a half they were through the Rockies, and
the _Albatross_ resumed her former speed of sixty-two miles an hour.
She was steering southwest so as to cut across Utah diagonally as she
neared the ground. She had even dropped several hundred yards when
the sound of a whistle attracted the attention of Uncle Prudent and
Phil Evans. It was a train on the Pacific Railway on the road to Salt
Lake City.

And then, in obedience to an order secretly given, the _Albatross_
dropped still lower so as to chase the train, which was going at full
speed. She was immediately sighted. A few heads showed themselves at
the doors of the cars. Then numerous passengers crowded the gangways.
Some did not hesitate to climb on the roof to get a better view of
the flying machine. Cheers came floating up through the air; but no
Robur appeared in answer to them.

The _Albatross_ continued her descent, slowing her suspensory screws
and moderating her speed so as not to leave the train behind. She
flew about it like an enormous beetle or a gigantic bird of prey. She
headed off, to the right and left, and swept on in front, and hung
behind, and proudly displayed her flag with the golden sun, to which
the conductor of the train replied by waving the Stars and Stripes.

In vain the prisoners, in their desire to take advantage of the
opportunity, endeavored to make themselves known to those below. In
vain the president of the Weldon Institute roared forth at the top of
his voice, "I am Uncle Prudent of Philadelphia!" And the secretary
followed suit with, "I am Phil Evans, his colleague!" Their shouts
were lost in the thousand cheers with which the passengers greeted
the aeronef.

Three or four of the crew of the _Albatross_ had appeared on the
deck, and one of them, like sailors when passing a ship less speedy
than their own, held out a rope, an ironical way of offering to tow
them.

And then the _Albatross_ resumed her original speed, and in half an
hour the express was out of sight. About one o'clock there appeared a
vast disk, which reflected the solar rays as if it were an immense
mirror.

"That ought to be the Mormon capital, Salt Lake City," said Uncle
Prudent. And so it was, and the disk was the roof of the Tabernacle,
where ten thousand saints can worship at their ease. This vast dome,
like a convex mirror, threw off the rays of the sun in all directions.

It vanished like a shadow, and the _Albatross_ sped on her way to the
southwest with a speed that was not felt, because it surpassed that
of the chasing wind. Soon she was in Nevada over the silver regions,
which the Sierra separates from the golden lands of California.

"We shall certainly reach San Francisco before night," said Phil
Evans.

"And then?" asked Uncle Prudent.

It was six o'clock precisely when the Sierra Nevada was crossed by
the same pass as that taken by the railway. Only a hundred and eighty
miles then separated them from San Francisco, the Californian capital.

At the speed the _Albatross_ was going she would be over the dome by
eight o'clock.

At this moment Robur appeared on deck. The colleagues walked up to
him.

"Engineer Robur," said Uncle Prudent, "we are now on the very
confines of America! We think the time has come for this joke to end."

"I never joke," said Robur.

He raised his hand. The _Albatross_ swiftly dropped towards the
ground, and at the same time such speed was given her as to drive the
prisoners into their cabin. As soon as the door was shut, Uncle
Prudent exclaimed,

"I could strangle him!"

"We must try to escape." said Phil Evans.

"Yes; cost what it may!"

A long murmur greeted their ears. It was the beating of the surf on
the seashore. It was the Pacific Ocean!

Chapter XI

THE WIDE PACIFIC

Uncle Prudent and Phil Evans had quite made up their minds to escape.
If they had not had to deal with the eight particularly vigorous men
who composed the crew of the aeronef they might have tried to succeed
by main force. But as they were only two - for Frycollin could only
be considered as a quantity of no importance - force was not to be
thought of. Hence recourse must be had to strategy as soon as the
_Albatross_ again took the ground. Such was what Phil Evans
endeavored to impress on his irascible colleague, though he was in
constant fear of Prudent aggravating matters by some premature
outbreak.

In any case the present was not the time to attempt anything of the
sort. The aeronef was sweeping along over the North Pacific. On the
following morning, that of June 16th, the coast was out of sight. And
as the coast curves off from Vancouver Island up to the Aleutians -
belonging to that portion of America ceded by Russia to the United
States in 1867 - it was highly probable that the _Albatross_ would
cross it at the end of the curve, if her course remained unchanged.

How long the night appeared to be to the two friends! How eager they
were to get out of their cabins! When they came on deck in the
morning the dawn had for some hours been silvering the eastern
horizon. They were nearing the June solstice, the longest day of the
year in the northern hemisphere, when there is hardly any night along
the sixtieth parallel.

Either from custom or intention Robur was in no hurry to leave his
deck-house, When he came out this morning be contented himself with
bowing to his two guests as he passed them in the stern of the
aeronef.

And now Frycollin ventured out of his cabin. His eyes red with
sleeplessness, and dazed in their look, he tottered along, like a man
whose foot feels it is not on solid ground. His first glance was at
the suspensory screws, which were working with gratifying regularity
without any signs of haste. That done, the Negro stumbled along to
the rail, and grasped it with both hands, so as to make sure of his
balance. Evidently he wished to view the country over which the
_Albatross_ was flying at the height of seven hundred feet or more.

At first he kept himself well back behind the rail. Then he shook it
to make sure it was firm; then he drew himself up; then he bent
forward; then he stretched out his head. It need not be said that
while he was executing these different maneuvers he kept his eyes
shut. At last he opened them.

What a shout! And how quickly he fled! And how deeply his head sank
back into his shoulders! At the bottom of the abyss he had seen the
immense ocean. His hair would have risen on end - if it had not been
wool.

"The sea! The sea!" he cried. And Frycollin would have fallen on the
deck had not the cook opened his arms to receive him.

This cook was a Frenchman, and probably a Gascon, his name being
Francois Tapage. If he was not a Cascon he must in his infancy have
inhaled the breezes of the Garonne. How did this Francois Tapage find
himself in the service of the engineer? By what chain of accidents
had be become one of the crew of the _Albatross?_ We can hardly say;
but in any case be spoke English like a Yankee. "Eh, stand up!" he
said, lifting the Negro by a vigorous clutch at the waist.

"Master Tapage!" said the poor fellow, giving a despairing look at
the screws.

"At your service, Frycollin."

"Did this thing ever smash?"

"No, but it will end by smashing."

"Why? Why?"

"Because everything must end.

"And the sea is beneath us!"

"If we are to fall, it is better to fall in the sea."

"We shall be drowned."

"We shall be drowned, but we shall not be smashed to a jelly."

The next moment Frycollin was on all fours, creeping to the back of
his cabin.

During this day the aeronef was only driven at moderate speed. She
seemed to skim the placid surface of the sea, which lay beneath.
Uncle Prudent and his companion remained in their cabin, so that they
did not meet with Robur, who walked about smoking alone or talking to
the mate. Only half the screws were working, yet that was enough to
keep the apparatus afloat in the lower zones of the atmosphere,

The crew, as a change from the ordinary routine, would have
endeavored to catch a few fish had there been any sign of them; but
all that could be seen on the surface of the sea were a few of those
yellow-bellied whales which measure about eighty feet in length.
These are the most formidable cetaceans in the northern seas, and
whalers are very careful in attacking them, for their strength is
prodigious. However, in harpooning one of these whales, either with
the ordinary harpoon, the Fletcher fuse, or the javelin-bomb, of
which there was an assortment on board, there would have been danger
to the men of the _Albatross._

But what was the good of such useless massacre? Doubtless to show off
the powers of the aeronef to the members of the Weldon Institute. And
so Robur gave orders for the capture of one of these monstrous
cetaceans.

At the shout of "A whale! "A whale!" Uncle Prudent and Phil Evans
came out of their cabin. Perhaps there was a whaler in sight! In that
case all they had to do to escape from their flying prison was to
jump into the sea, and chance being picked up by the vessel.

The crew were all on deck. "Shall we try, sir?" asked Tom Turner.

"Yes," said Robur.

In the engine-room the engineer and his assistant were at their posts
ready to obey the orders signaled to them. The _Albatross_ dropped
towards the sea, and remained, about fifty feet above it.

There was no ship in sight - of that the two colleagues soon assured
themselves - nor was there any land to be seen to which they could
swim, providing Robur made no attempt to recapture them.

Several jets of water from the spout holes soon announced the
presence of the whales as they came to the surface to breathe. Tom
Turner and one of the men were in the bow. Within his reach was one
of those javelin-bombs, of Californian make, which are shot from an
arquebus and which are shaped as a metallic cylinder terminated by a
cylindrical shell armed with a shaft having a barbed point. Robur was
a little farther aft, and with his right hand signaled to the
engineers, while with his left, he directed the steersman. He thus
controlled the aeronef in every way, horizontally and vertically, and
it is almost impossible to conceive with what speed and precision the
_Albatross_ answered to his orders. She seemed a living being, of
which he was the soul.

"A whale! A whale!" shouted Tom Turner, as the back of a cetacean
emerged from the surface about four cable-lengths in front of the
_Albatross._

The _Albatross_ swept towards it, and when she was within sixty feet
of it she stopped dead.

Tom Turner seized the arquebus, which was resting against a cleat on
the rail. He fired, and the projectile, attached to a long line,
entered the whale's body. The shell, filled with an explosive
compound, burst, and shot out a small harpoon with two branches,
which fastened into the animal's flesh.

"Look out!" shouted Turner.

Uncle Prudent and Phil Evans, much against their will, became greatly
interested in the spectacle.

The whale, seriously wounded, gave the sea such a slap with his tail,
that the water dashed up over the bow of the aeronef. Then he plunged
to a great depth, while the line, which had been previously wetted in
a tub of water to prevent its taking fire, ran out like lightning.
When the whale rose to the surface he started off at full speed in a
northerly direction.

It may be imagined with what speed the _Albatross_ was towed in
pursuit. Besides, the propellers had been stopped. The whale was let
go as he would, and the ship followed him. Turner stood ready to cut
the line in case a fresh plunge should render this towing dangerous.

For half an hour, and perhaps for a distance of six miles, the
_Albatross_ was thus dragged along, but it was obvious that the whale
was tiring. Then, at a gesture from Robur the assistant engineers
started the propellers astern, so as to oppose a certain resistance
to the whale, who was gradually getting closer.

Soon the aeronef was gliding about twenty-five feet above him. His
tail was beating the waters with incredible violence, and as he
turned over on his back an enormous wave was produced.

Suddenly the whale turned up again, so as to take a header, as it
were, and then dived with such rapidity that Turner had barely time
to cut the line.

The aeronef was dragged to the very surface of the water. A whirlpool
was formed where the animal had disappeared. A wave dashed up on to
the deck as if the aeronef were a ship driving against wind an tide,

Luckily, with a blow of the hatchet the mate severed the line, and
the _Albatross,_ freed from her tug, sprang aloft six hundred feet
under the impulse of her ascensional screws. Robur had maneuvered his
ship without losing his coolness for a moment.

A few minutes afterwards the whale returned to the surface - dead.
From every side the birds flew down on to the carcass, and their
cries were enough to deafen a congress. The _Albatross,_ without
stopping to share in the spoil, resumed her course to the west.

In the morning of the 17th of June, at about six o'clock, land was
sighted on the horizon. This was the peninsula of Alaska, and the
long range of breakers of the Aleutian Islands.

The _Albatross_ glided over the barrier where the fur seals. swarm
for the benefit of the Russo-American Company. An excellent business
is the capture of these amphibians, which are from six to seven feet
long, russet in color, and weigh from three hundred to four hundred
pounds. There they were in interminable files, ranged in line of
battle, and countable by thousands.

Although they did not move at the passage of the _Albatross,_ it was
otherwise with the ducks, divers, and loons, whose husky cries filled
the air as they disappeared beneath the waves and fled terrified from
the aerial monster.

The twelve hundred miles of the Behring Sea between the first of the
Aleutians and the extreme end of Kamtschatka were traversed during
the twenty-four hours of this day and the following night. Uncle
Prudent and Phil Evans found that here was no present chance of
putting their project of escape into execution. Flight was not to be
thought of among the deserts of Eastern Asia, nor on the coast of the
sea of Okhotsk. Evidently the _Albatross_ was bound for Japan or
China, and there, although it was not perhaps quite safe to trust
themselves to the, mercies of the Chinese or Japanese, the two
friends had made up their minds to run if the aeronef stopped.

But would she stop? She was not like a bird which grows fatigued by
too long a flight, or like a balloon which has to descend for want of
gas. She still had food for many weeks and her organs were of
marvelous strength, defying all weakness and weariness.

During the 18th of June she swept over the peninsula of Kamtschatka,
and during the day there was a glimpse of Petropaulovski and the
volcano of Kloutschew. Then she rose again to cross the Sea of
Okhotsk, running down by the Kurile Isles, which seemed to be a
breakwater pierced by hundreds of channels. On the 19th, in the
morning, the _Albatross_ was over the strait of La Perouse between
Saghalien and Northern Japan, and had reached the mouth of the great
Siberian river, the Amoor.

Then there came a fog so dense that the aeronef had to rise above it.
At the altitude she was there was no obstacle to be feared, no
elevated monuments to hinder her passage, no mountains against which
there was risk of being shattered in her flight. The country was only
slightly varied. But the fog was very disagreeable, and made
everything on board very damp.

All that was necessary was to get above this bed of mist, which was
nearly thirteen hundred feet thick, and the ascensional screws being
increased in speed, the _Albatross_ was soon clear of the fog and in
the sunny regions of the sky. Under these circumstances, Uncle
Prudent and Phil Evans would have found some difficulty in carrying
out their plan of escape, even admitting that they could leave the
aeronef.

During the day, as Robur passed them he stopped for a moment, and
without seeming to attach any importance to what he said, addressed
them carelessly as follows: "Gentlemen, a sailing-ship or a steamship
caught in a fog from which it cannot escape is always much delayed.
It must not move unless it keeps its whistle or its horn going. It
must reduce its speed, and any instant a collision may be expected.
The _Albatross_ has none of these things to fear. What does fog
matter to her? She can leave it when she chooses. The whole of space
is hers." And Robur continued his stroll without waiting for an
answer, and the puffs of his pipe were lost in the sky.

"Uncle Prudent," said Phil Evans, "it seems that this astonishing
_Albatross_ never has anything to fear."

"That we shall see!" answered the president of the Weldon Institute.

"The fog lasted three days, the 19th, 20th, and 21st of June, with
regrettable persistence. An ascent had to be made to clear the
Japanese mountain of Fujiyama. When the curtain of mist was drawn
aside there lay below them an immense city, with palaces, villas,
gardens, and parks. Even without seeing it Robur had recognized it by
the barking of the innumerable dogs, the cries of the birds of prey,
and above all, by the cadaverous odor which the bodies of its
executed criminals gave off into space.

The two colleagues were out on the deck while the engineer was taking
his observations in case. he thought it best to continue his course
through the fog.

"Gentlemen," said he, "I have no reason for concealing from you that
this town is Tokyo, the capital of Japan."

Uncle Prudent did not reply. In the presence of the engineer he was
almost choked, as if his lungs were short of air.

"This view of Tokyo," continued Robur, "is very curious."

"Curious as it may be -" replied Phil Evans.

"It is not as good as Peking?" interrupted the engineer.

"That is what I think, and very shortly you shall have an opportunity
of judging."

Impossible to be more agreeable!

The _Albatross_ then gliding southeast, had her course changed four
points, so as to head to the eastward.

Chapter XII

THROUGH THE HIMALAYAS

During, the night the fog cleared off. There were symptoms of an
approaching typhoon - a rapid fall of the barometer, a disappearance
of vapor, large clouds of ellipsoid form clinging to a copper sky,
and, on the opposite horizon, long streaks of carmine on a
slate-colored field, with a large sector quite clear in the north.
Then the sea was smooth and calm and at sunset assumed a deep scarlet
hue.

Fortunately the typhoon broke more to the south, and had no other
result than to sweep away the mist which had been accumulating during
the last three days.

In an hour they had traversed the hundred and twenty-five miles of
the Korean strait, and while the typhoon was raging on the coast of
China, the _Albatross_ was over the Yellow Sea. During the 22nd and
23rd she was over the Gulf of Pechelee, and on the 24th she was
ascending the valley of the Peiho on her way to the capital of the
Celestial Empire.

Leaning over the rail, the two colleagues, as the engineer had told
them, could see distinctly the immense city, the wall which divides
it into two parts - the Manchu town, and the Chinese town - the
twelve suburbs which surround it, the large boulevards which radiate
from its center, the temples with their green and yellow roofs bathed
in the rising sun, the grounds surrounding the houses of the
mandarins; then in the middle of the Manchu town the eighteen hundred
acres of the Yellow town, with its pagodas, its imperial gardens, its
artificial lakes, its mountain of coal which towers above the
capital; and in the center of the Yellow town, like a square of
Chinese puzzle enclosed in another, the Red town, that is the
imperial palace, with all the peaks of its outrageous architecture.

Below the _Albatross_ the air was filled with a singular harmony. It
seemed to be a concert of Aeolian harps. In the air were a hundred
kites of different forms, made of sheets of palm-leaf, and having at
their upper end a sort of bow of light wood with a thin slip of
bamboo beneath. In the breath of the wind these slips, with all their
notes varied like those of a harmonicon, gave forth a most melancholy
murmuring. It seemed as though they were breathing musical oxygen.

It suited Robur's whim to run close up to this aerial orchestra, and
the _Albatross_ slowed as she glided through the sonorous waves which
the kites gave off through the atmosphere.

But immediately an extraordinary effect was produced amongst the
innumerable population. Beatings of the tomtoms and sounds of other
formidable instruments of the Chinese orchestra, gun reports by the
thousand, mortars fired in hundreds, all were brought into play to
scare away the aeronef. Although the Chinese astronomers may have
recognized the aerial machine as the moving body that had given rise
to such disputes, it was to the Celestial million, from the humblest
tankader to the best-buttoned mandarin, an apocalyptical monster
appearing in the sky of Buddha.

The crew of the _Albatross_ troubled themselves very little about
these demonstrations. But the strings which held the kites, and were
tied to fixed pegs in the imperial gardens, were cut or quickly
hauled in; and the kites were either drawn in rapidly, sounding
louder as they sank, or else fell like a bird shot through both
wings, whose song ends with its last sigh.

A noisy fanfare escaped from Tom Turner's trumpet, and drowned the
final notes of the aerial concert. It did not interrupt the
terrestrial fusillade. At last a shell exploded a few feet below the
_Albatross,_ and then she mounted into the inaccessible regions of
the sky.

Nothing happened during the few following days of which the prisoners
could take advantage. The aeronef kept on her course to the
southwest, thereby showing that it was intended to take her to India.
Twelve hours after leaving Peking, Uncle Prudent and Phil Evans
caught a glimpse of the Great Wall in the neighborhood of Chen-Si.
Then, avoiding the Lung Mountains, they passed over the valley of the
Hoangho and crossed the Chinese border on the Tibet side.

Tibet consists of high table-lands without vegetation, with here and
there snowy peaks and barren ravines, torrents fed by glaciers,
depressions with glittering beds of salt, lakes surrounded by
luxurious forests, with icy winds sweeping over all.

The barometer indicated an altitude of thirteen thousand feet above
the level of the sea. At that height the temperature, although it was
in the warmest months of the northern hemisphere, was only a little
above freezing. This cold, combined with the speed of the
_Albatross,_ made the voyage somewhat trying, and although the
friends had warm traveling wraps, they preferred to keep to their
cabin.

It need hardly be said that to keep the aeronef in this rarefied
atmosphere the suspensory screws had to be driven at extreme speed.
But they worked with perfect regularity, and the sound of their wings
almost acted as a lullaby.

During this day, appearing from below about the size of a carrier
pigeon, she passed over Garlock, a town of western Tibet, the capital
of the province of Cari Khorsum.

On the 27th of June, Uncle Prudent and Phil Evans sighted an enormous
barrier, broken here and there by several peaks, lost in the snows
that bounded the horizon.

Leaning against the fore-cabin, so as to keep their places
notwithstanding the speed of the ship, they watched these colossal
masses, which seemed to be running away from the aeronef.

"The Himalayas, evidently," said Phil Evans; "and probably Robur is
going round their base, so as to pass into India."

"So much the worse," answered Uncle Prudent. "On that immense
territory we shall perhaps be able to -"

"Unless he goes round by Burma to the east, or Nepal to the West."

"Anyhow, I defy him to go through them."

"Indeed!" said a voice.

The next day, the 28th of June, the _Albatross_ was in front of the
huge mass above the province of Zang. On the other side of the chain
was the province of Nepal. These ranges block the road into India
from the north. The two northern ones, between which the aeronef was
gliding like a ship between enormous reefs are the first steps of the
Central Asian barrier. The first was the Kuen Lung, the other the
Karakorum, bordering the longitudinal valley parallel to the
Himalayas, from which the Indus flows to the west and the
Brahmapootra to the east.

What a superb orographical system! More than two hundred summits have
been measured, seventeen of which exceed twenty-five thousand feet.
In front of the _Albatross,_ at a height of twenty-nine thousand
feet, towered Mount Everest. To the right was Dhawalagiri, reaching
twenty-six thousand eight hundred feet, and relegated to second place
since the measurement of Mount Everest.

Evidently Robur did not intend to go over the top of these peaks; but
probably he knew the passes of the Himalayas, among others that of
Ibi Ganim, which the brothers Schlagintweit traversed in 1856 at a
height of twenty-two thousand feet. And towards it he went.

Several hours of palpitation, becoming quite painful followed; and
although the rarefaction of the air was not such as to necessitate
recourse being had to the special apparatus for renewing oxygen in
the cabins, the cold was excessive.

Robar stood in the bow, his sturdy figure wrapped in a great-coat. He
gave the orders, while Tom Turner was at the helm. The engineer kept
an attentive watch on his batteries, the acid in which fortunately
ran no risk of congelation. The screws, running at the full strength
of the current, gave forth a note of intense shrillness in spite of
the trifling density of the air. The barometer showed twenty-three
thousand feet in altitude.

Magnificent was the grouping of the chaos of mountains! Everywhere
were brilliant white summits. There were no lakes, but glaciers
descending ten thousand feet towards the base. There was no herbage,
only a few phanerogams on the limit of vegetable life. Down on the
lower flanks of the range were splendid forests of pines and cedars.
Here were none of the gigantic ferns and interminable parasites
stretching from tree to tree as in the thickets of the jungle. There
were no animals -no wild horses, or yaks, or Tibetan bulls.
Occasionally a scared gazelle showed itself far down the slopes.
There were no birds, save a couple of those crows which can rise to
the utmost limits of the respirable air.

The pass at last was traversed. The _Albatross_ began to descend.
Coming from the hills out of the forest region there was now beneath
them an immense plain stretching far and wide.

Then Robur stepped up to his guests, and in a pleasant voice
remarked, "India, gentlemen!"

Chapter XIII

OVER THE CASPIAN

The Engineer had no intention of taking his ship over the wondrous
lands of Hindustan. To cross the Himalayas was to show how admirable
was the machine he commanded; to convince those who would not be
convinced was all he wished to do.

But if in their hearts Uncle Prudent and his colleague could not help
admiring so perfect an engine of aerial locomotion, they allowed none
of their admiration to be visible. All they thought of was how to
escape. They did not even admire the superb spectacle that lay
beneath them as the _Albatross_ flew along the river banks of the
Punjab.

At the base of the Himalayas there runs a marshy belt of country, the
home of malarious vapors, the Terai, in which fever is endemic. But
this offered no obstacle to the _Albatross,_ or, in any way, affected
the health of her crew. She kept on without undue haste towards the
angle where India joins on to China and Turkestan, and on the 29th of
June, in the early hours of the morning, there opened to view the
incomparable valley of Cashmere.

Yes! Incomparable is this gorge between the major and the minor
Himalayas - furrowed by the buttresses in which the mighty range dies
out in the basin of the Hydaspes, and watered by the capricious
windings of the river which saw the struggle between the armies of
Porus and Alexander, when India and Greece contended for Central
Asia. The Hydaspes is still there, although the two towns founded by
the Macedonian in remembrance of his victory have long since
disappeared.

During the morning the aeronef was over Serinuggur, which is better
known under the name of Cashmere. Uncle Prudent and his companion
beheld the superb city clustered along both banks of the river; its
wooden bridges stretching across like threads, its villas and their
balconies standing out in bold outline, its hills shaded by tall
poplars, its roofs grassed over and looking like molehills; its
numerous canals, with boats like nut-shells, and boatmen like ants;
its palaces, temples, kiosks, mosques, and bungalows on the
outskirts; and its old citadel of Hari-Pawata on the slope of the
hill like the most important of the forts of Paris on the slope of
Mont Valerien.

"That would be Venice," said Phil Evans, "if we were in Europe."

"And if we,were in Europe," answered Uncle Prudent, "we should know
how to find the way to America."

The _Albatross_ did not linger over the lake through which the river
flows, but continued her flight down the valley of the Hydaspes.

For half an hour only did she descend to within thirty feet of the
river and remained stationary. Then, by means of an india-rubber
pipe, Tom Turner and his men replenished their water supply, which
was drawn up by a pump worked by the accumulators. Uncle Prudent and
Phil Evans stood watching the operation. The same idea occurred to
each of them. They were only a few feet from the surface of the
stream. They were both good swimmers. A plunge would give them their
liberty; and once they had reached the river, how could Robur get
them back again? For his propellers to work, he must keep at least
six feet above the ground.

In a moment all the chances pro and con were run over in their heads.
In a moment they were considered, and the prisoners rushed to throw
themselves overboard, when several pairs of hands seized them by the
shoulders.

They had been watched; and flight was utterly impossible.

This time they did not yield without resisting. They tried to throw
off those who held them. But these men of the _Albatross_ were no
children.

"Gentlemen," said the engineer, "when people, have the pleasure of
traveling with Robur the Conqueror, as you have so well named him, on
board his admirable _Albatross,_ they do not leave him in that way. I
may add you never leave him."

Phil Evans drew away his colleague, who was about to commit some act
of violence. They retired to their cabin, resolved to escape, even if
it cost them their lives.

Immediately the _Albatross_ resumed her course to the west. During
the day at moderate speed she passed over the territory of
Cabulistan, catching a momentary glimpse of its capital, and crossed
the frontier of the kingdom of Herat, nearly seven hundred miles from
Cashmere.

In these much-disputed countries, the open road for the Russians to
the English possessions in India, there were seen many columns and
convoys, and, in a word, everything that constitutes in men and
material an army on the march. There were heard also the roar of the
cannon and the crackling of musketry. But the engineer never meddled
with the affairs of others where his honor or humanity was not
concerned. He passed above them. If Herat as we are told, is the key
of Central Asia, it mattered little to him if it was kept in an
English or Muscovite pocket. Terrestrial interests were nothing to
him who had made the air his domain.

Besides, the country soon disappeared in one of those sandstorms
which are so frequent in these regions. The wind called the "tebbad"
bears along the seeds of fever in the impalpable dust it raises in
its passage. And many are the caravans that perish in its eddies.

To escape this dust, which might have interfered with the working of
the screws, the _Albatross_ shot up some six thousand feet into a
purer atmosphere.

And thus vanished the Persian frontier and the extensive plains. The
speed was not excessive, although there were no rocks ahead, for the
mountains marked on the map are of very moderate altitude. But as the
ship approached the capital, she had to steer clear of Demavend,
whose snowy peak rises some twenty-two thousand feet, and the chain
of Elbruz, at whose foot is built Teheran.

As soon as the day broke on the 2nd of July the peak of Demavend
appeared above the sandstorm, and the _Albatross_ was steered so as
to pass over the town, which the wind had wrapped in a mantle of dust.

However, about six eclock her crew could see the large ditches that
surround it, and the Shah's palace, with its walls covered with
porcelain tiles, and its ornamental lakes, which seemed like huge
turquoises of beautiful blue.

It was but a hasty glimpse. The _Albatross_ now headed for the north,
and a few hours afterwards she was over a little hill at the northern
angle of the Persian frontier, on the shores of a vast extent of
water which stretched away out of sight to the north and east.

The town was Ashurada, the most southerly of the Russian stations.
The vast extent of water was a sea. It was the Caspian.

The eddies of sand bad been passed. There was a view of a group of
European houses rising along a promontory, with a church tower in the
midst of them.

The _Albatross_ swooped down towards the surface of the sea. Towards
evening she was running along the coast-which formerly belonged to
Turkestan, but now belongs to Russia - and in the morning of the 3rd
of July she was about three hundred feet above the Caspian.

There was no land in sight, either on the Asiatic or European side.
On the surface of the sea a few white sails were bellying in the
breeze. These were native vessels recognizable by their peculiar
rig-kesebeys, with two masts; kayuks, the old pirate-boats, with one
mast; teimils, and smaller craft for trading and fishing. Here and
there a few puffs of smoke rose up to the _Albatross_ from the
funnels of the Ashurada streamers, which the Russians keep as the
police of these Turcoman waters.

That morning Tom Turner was talking to the cook, Tapage, and to a
question of his replied, "Yes; we shall be about forty-eight hours
over the Caspian."

"Good!" said the cook; "Then we can have some fishing."

"Just so."

They were to remain for forty-eight hours over the Caspian, which is
some six hundred and twenty-five miles long and two hundred wide,
because the speed of the _Albatross_ had been much reduced, and while
the fishing was going on she would be stopped altogether.

The reply was heard by Phil Evans, who was then in the bow, where
Frycollin was overwhelming him with piteous pleadings to be put "on
the ground."

Without replying to this preposterous request, Evans returned aft to
Uncle Prudent; and there, taking care not to be overheard, he
reported the conversation that had taken place.

"Phil Evans," said Uncle Prudent, "I think there can be no mistake as
to this scoundrel's intention with regard to us."

"None," said Phil Evans. "He will only give us our liberty when it
suits him, and perhaps not at all."

"In that case we must do all we can to get away from the _Albatross._"

"A splendid craft, she is, I must admit."

"Perhaps so," said Uncle Prudent; "but she belongs to a scoundrel who
detains us on board in defiance of all right. For us and ours she is
a constant danger. If we do not destroy her -"

"Let us begin by saving ourselves" answered Phil Evans; we can see
about the destruction afterwards."

"Just so," said Uncle Prudent. "And we must avail ourselves of every
chance that comes, along. Evidently the _Albatross_ is going to cross
the Caspian into Europe, either by the north into Russia or by the
west into the southern countries. Well, no matter where we stop,
before we get to the Atlantic, we shall be safe. And we ought to be
ready at any moment."

"But," asked Evans, "how are we to get out?"

"Listen to me," said Uncle Prudent. "It may happen during the night
that the _Albatross_ may drop to within a few hundred feet of the
ground. Now there are on board several ropes of that length, and,
with a little pluck we might slip down them -"

"Yes," said Evans. "If the case is desperate I don't mind -"

"Nor I. During the night there's no one about except the man at the
wheel. And if we can drop one of the ropes forward without being seen
or heard -"

"Good! I am glad to see you are so cool; that means business. But
just now we are over the Caspian. There are several ships in sight.
The _Albatross_ is going down to fish. Cannot we do something now?"

"Sh! They are watching us much more than you think," said Uncle
Prudent. "You saw that when we tried to jump into the Hydaspes."

"And who knows that they don't watch us at night?" asked Evans.

"Well, we must end this; we must finish with this _Albatross_ and her
master."

It will he seen how in the excitement of their anger the colleagues -
Uncle Prudent in particular - were prepared to attempt the most
hazardous things. The sense of their powerlessness, the ironical
disdain with which Robur treated them, the brutal remarks he indulged
in - all contributed towards intensifying the aggravation which daily
grew more manifest.

This very day something occurred which gave rise to another most
regrettable altercation between Robur and his guests. This was
provoked by Frycollin, who, finding himself above the boundless sea,
was seized with another fit of terror. Like a child, like the Negro
he was, he gave himself over to groaning and protesting and crying,
and writhing in a thousand contortions and grimaces.

"I want to get out! I want to get out! I am not a bird! Boohoo! I
don't want to fly, I want to get out!"

Uncle Prudent, as may be imagined, did not attempt to quiet him. In
fact, he encouraged him, and particularly as the incessant howling
seemed to have a strangely irritating effect on Robur.

When Tom Turner and his companions were getting ready for fishing,
the engineer ordered them to shut up Frycollin in his cabin. But the
Negro never ceased his jumping about, and began to kick at the wall
and yell with redoubled power.

It was noon. The _Albatross_ was only about fifteen or twenty feet
above the water. A few ships, terrified at the apparition, sought
safety in flight.

As may be guessed, a sharp look-out was kept on the prisoners, whose
temptation to escape could not but be intensified. Even supposing
they jumped overboard they would have been picked up by the
india-rubber boat. As there was nothing to do during the fishing, in
which Phil Evans intended to take part, Uncle Prudent, raging
furiously as usual, retired to his cabin.

The Caspian Sea is a volcanic depression. Into it flow the waters of
the Volga, the Ural, the Kour, the Kouma, the Jemba, and others.
Without the evaporation which relieves it of its overflow, this
basin, with an area of 17,000 square miles, and a depth of from sixty
to four hundred feet, would flood the low marshy ground to its north
and east. Although it is not in communication with the Black Sea or
the Sea of Aral, being at a much lower level than they are, it
contains an immense number of fish - such fish, be it understood, as
can live in its bitter waters, the bitterness being due to the naptha
which pours in from the springs on the south.

The crew of the _Albatross_ made no secret of their delight at the
change in their food the fishing would bring them.

"Look out!" shouted Turner, as he harpooned a good-size fish, not
unlike a shark.

It was a splendid sturgeon seven feet long, called by the Russians
beluga, the eggs of which mixed up with salt, vinegar, and white wine
form caviar. Sturgeons from the river are, it may be, rather better
than those from the sea; but these were welcomed warmly enough on
board the _Albatross._

But the best catches were made with the drag-nets, which brought up
at each haul carp, bream, salmon, saltwater pike, and a number of
medium-sized sterlets, which wealthy gourmets have sent alive to
Astrakhan, Moscow, and Petersburg, and which now passed direct from
their natural element into the cook's kettle without any charge for
transport.

An hour's work sufficed to fill up the larders of the aeronef, and
she resumed her course to the north.

During the fishing Frycollin had continued shouting and kicking at
his cabin wall,and making a tremendous noise.

"That wretched nigger will not be quiet, then?" said Robur, almost
out of patience.

"It seems to me, sir, he has a right to complain," said Phil Evans.

"Yes, and I have a right to look after my ears," replied Robur.

"Engineer Robur!" said Uncle Prudent, who had just appeared on deck.

"President of the Weldon Institute!"

They had stepped up to one another, and were looking into the whites
of each other's eyes. Then Robur shrugged his shoulders. "Put him at
the end of a line," he said.

Turner saw his meaning at once. Frycollin was dragged out of his
cabin. Loud were his cries when the mate and one of the men seized
him and tied him into a tub, which they hitched on to a rope - one of
those very ropes, in fact, that Uncle Prudent had intended to use as
we know.

The Negro at first thought he was going to be hanged. Not he was only
going to be towed!

The rope was paid out for a hundred feet and Frycollin found himself
hanging in space.

He could then shout at his ease. But fright contracted his larynx,
and he was mute.

Uncle Prudent and Phil Evans endeavored to prevent this performance.
They were thrust aside.

"It is scandalous! It is cowardly!" said Uncle Prudent, quite beside
himself with rage.

"Indeed!" said Robur.

"It is an abuse of power against which I protest."

"Protest away!"

"I will be avenged, Mr. Robur."

"Avenge when you like, Mr. Prudent."

"I will have my revenge on you and yours."

The crew began to close up with anything but peaceful intentions.
Robur motioned them away.

"Yes, on you and yours!" said Uncle Prudent, whom his colleague in
vain tried to keep quiet.

"Whenever you please!" said the engineer.

"And in every possible way!"

"That is enough now," said Robur, in a threatening tone. "There are
other ropes on board. And if you don't be quiet I'll treat you as I
have done your servant!"

Uncle Prudent was silent, not because he was afraid, but because his
wrath had nearly choked him; and Phil Evans led him off to his cabin.

During the last hour the air had been strangely troubled. The
symptoms could not be mistaken. A storm was threatening. The electric
saturation of the atmosphere had become so great that about half-past
two o'clock Robur witnessed a phenomenon that was new to him.

In the north, whence the storm was traveling, were spirals of
half-luminous vapor due to the difference in the electric charges of
the various beds of cloud. The reflections of these bands came
running along the waves in myriads of lights, growing in intensity as
the sky darkened.

The _Albatross_ and the storm we're sure to meet, for they were
exactly in front of each other.

And Frycollin? Well! Frycollin was being towed - and towed is exactly
the word, for the rope made such an angle, with the aeronef, now
going at over sixty knots an hour, that the tub was a long way behind
her.

The crew were busy in preparing for the storm, for the _Albatross_
would either have to rise above it or drive through its lowest
layers. She was about three thousand feet above the sea when a clap
of thunder was heard. Suddenly the squall struck her. In a few
seconds the fiery clouds swept on around her.

Phil Evans went to intercede for Frycollin, and asked for him to be
taken on board again. But Robur had already given orders to that
effect, and the rope was being hauled in, when suddenly there took
place an inexplicable slackening in the speed of the screws.

The engineer rushed to the central deck-house. "Power! More power!"
he shouted. "We must rise quickly and get over the storm!"

"Impossible, sir!"

"What is the matter?"

"The currents are troubled! They are intermittent!" And, in fact, the
_Albatross_ was falling fast.

As with the telegraph wires on land during a storm, so was it with
the accumulators of the aeronef. But what is only an inconvenience in
the case of messages was here a terrible danger.

"Let her down, then," said Robur, "and get out of the electric zone!
Keep cool, my lads!"

He stepped on to his quarter-deck and his crew went to their stations.

Although the _Albatross_ had sunk several hundred feet she was still
in the thick of the cloud, and the flashes played across her as if
they were fireworks. It seemed as though she was struck. The screws
ran more and more slowly, and what began as a gentle descent
threatened to become a collapse.

In less than a minute it was evident they would get down to the
surface of the sea. Once they were immersed no power could drag them
from the abyss.

Suddenly the electric cloud appeared above them. The _Albatross_ was
only sixty feet from the crest of the waves. In two or three seconds
the deck would be under water.

But Robur, seizing the propitious moment, rushed to the central house
and seized the levers. He turned on the currents from the piles no
longer neutralized by the electric tension of the surrounding
atmosphere. In a moment the screws had regained their normal speed
and checked the descent; and the _Albatross_ remained at her slight
elevation while her propellers drove her swiftly out of reach of the
storm.

Frycollin, of course, had a bath - though only for a few seconds.
When he was dragged on deck he was as wet as if he had been to the
bottom of the sea. As may be imagined, he cried no more.

In the morning of the 4th of July the _Albatross_ had passed over the
northern shore of the Caspian.

Chapter XIV

THE AERONEF AT FULL SPEED

If ever Prudent and Evans despaired on escaping from the _Albatross_
it was during the two days that followed. It may be that Robur
considered it more difficult to keep a watch on his prisoners while
he was crossing Europe, and he knew that they had made up their minds
to get away.

But any attempt to have done so would have been simply committing
suicide. To jump from an express going sixty miles an hour is to risk
your life, but to jump from a machine going one hundred and twenty
miles an hour would be to seek your death.

And it was at this speed, the greatest that could be given to her,
that the _Albatross_ tore along. Her speed exceeded that of the
swallow, which is one hundred and twelve miles an hour.

At first the wind was in the northeast, and the _Albatross_ had it
fair, her general course being a westerly one. But the wind began to
drop, and it soon became impossible for the colleagues to remain on
the deck without having their breath taken away by the rapidity of
the flight. And on one occasion they would have been blown overboard
if they had not been dashed up against the deck-house by the pressure
of the wind.

Luckily the steersman saw them through the windows of his cage, and
by the electric bell gave the alarm to the men in the fore-cabin.
Four of them came aft, creeping along the deck.

Those who have been at sea, beating to windward in half a gale of
wind, will understand what the pressure was like. But here it was the
_Albatross_ that by her incomparable speed made her own wind.

To allow Uncle Prudent and Phil Evans to get back to their cabin the
speed had to be reduced. Inside the deck-house the _Albatross_ bore
with her a perfectly breathable atmosphere. To stand such driving the
strength of the apparatus must have been prodigious. The propellers
spun round so swiftly that they seemed immovable, and it was with
irresistible power that they screwed themselves through the air.

The last town that had been noticed was Astrakhan, situated at the
north end of the Caspian Sea. The Star of the Desert - it must have
been a poet who so called it - has now sunk from the first rank to
the fifth or sixth. A momentary glance was afforded at its old walls,
with their useless battlements, the ancient towers in the center of
the city, the mosques aud modern churches, the cathedral with its
five domes, gilded and dotted with stars as if it were a piece of the
sky, as they rose from the bank of the Volga, which here, as it joins
the sea, is over a mile in width.

Thenceforward the flight of the _Albatross_ became quite a race
through the heights of the sky, as if she had been harnessed to one
of those fabulous hippogriffs which cleared a league at every sweep
of the wing.

At ten o'clock in the morning, of the 4th of July the aeronef,
heading northwest, followed for a little the valley of the Volga. The
steppes of the Don and the Ural stretched away on each side of the
river. Even if it had been possible to get a glimpse of these vast
territorities there would have been no time to count the towns and
villages. In the evening the aeronef passed over Moscow without
saluting the flag on the Kremlin. In ten hours she had covered the
twelve hundred miles which separate Astrakhan from the ancient
capital of all the Russias.

From Moscow to St. Petersburg the railway line measures about seven
hundred and fifty miles. This was but a half-day's journey, and the
_Albatross,_ as punctual as the mail, reached St. Petersburg and the
banks of the Neva at two o'clock in the morning.

Then came the Gulf of Finland, the Archipelago of Abo, the Baltic,
Sweden in the latitude of Stockhohn, and Norway in the latitude of
Christiania. Ten hours only for these twelve hundred miles! Verily it
might be thought that no human power would henceforth be able to
check the speed of the _Albatross,_ and as if the resultant of her
force of projection and the attraction of the earth would maintain
her in an unvarying trajectory round the globe.

But she did stop nevertheless, and that was over the famous fall of
the Rjukanfos in Norway. Gousta, whose summit dominates this
wonderful region of Tellermarken, stood in the west like a gigantic
barrier apparently impassable. And when the _Albatross_ resumed her
journey at full speed her head had been turned to the south.

And during this extraordinary flight what was Frycollin doing? He
remained silent in a comer of his cabin, sleeping as well as he
could, except at meal times.

Tapage then favored him with his company and amused himself at his
expense. "Eh! eh! my boy!" said he. "So you are not crying any more?
Perhaps it hurt you too much? That two hours hanging cured you of it?
At our present rate, what a splendid air-bath you might have for your
rheumatics!"

"It seems to me we shall soon go to pieces!"

"Perhaps so; but we shall go so fast we shan't have time to fall!
That is some comfort!"

"Do you think so?"

"I do."

To tell the truth, and not to exaggerate like Tapage, it was only
reasonable that owing to the excessive speed the work of the
suspensory screws should be somewhat lessened. The _Albatross_ glided
on its bed of air like a Congreve rocket.

"And shall we last long like that?" asked Frycollin.

"Long? Oh, no, only as long as we live!"

"Oh!" said the Negro, beginning his lamentations.

"Take care, Fry, take care! For, as they say in my country, the
master may send you to the seesaw!" And Frycollin gulped down his
sobs as he gulped down the meat which, in double doses, he was
hastily swallowing.

Meanwhile Uncle Prudent and Phil Evans, who were not men to waste
time in wrangling when nothing could come of it, agreed upon doing
something. It was evident that escape was not to be thought of. But
if it was impossible for them to again set foot on the terrestrial
globe, could they not make known to its inhabitants what had become
of them since their disappearance, and tell them by whom they had
been carried off, and provoke - how was not very clear - some
audacious attempt on the part of their friends to rescue them from
Robur?

Communicate? But how? Should they follow the example of sailors in
distress and enclose in a bottle a document giving the place of
shipwreck and throw it into the sea? But here the sea was the
atmosphere. The bottle would not swim. And if it did not fall on
somebody and crack his skull it might never be found.

The colleagues were about to sacrifice one of the bottles on board
when an idea occurred to Uncle Prudent. He took snuff, as we know,
and we may pardon this fault in an American, who might do worse. And
as a snuff-taker he possessed a snuff-box, which was now empty. This
box was made of aluminum. If it was thrown overboard any honest
citizen that found it would pick it up, and, being an honest citizen,
he would take it to the police-office, and there they would open it
and discover from the document what had become of the two victims of
Robur the Conqueror!

And this is what was done. The note was short, but it told all, and
it gave the address of the Weldon Institute, with a request that it
might he forwarded. Then Uncle Prudent folded up the note, shut it in
the box, bound the box round with a piece of worsted so as to keep it
from opening it as it fell. And then all that had to be done was to
wait for a favorable opportunity.

During this marvelous flight over Europe it was not an easy thing to
leave the cabin and creep along the deck at the risk of being
suddenly and secretly blown away, and it would not do for the
snuff-box to fall into the sea or a gulf or a lake or a watercourse,
for it would then perhaps be lost. At the same time it was not
impossible that the colleagues might in this way get into
communication with the habitable globe.

It was then growing daylight, and it seemed as though it would be
better to wait for the night and take advantage of a slackening speed
or a halt to go out on deck and drop the precious snuff-box into some
town.

When all these points had been thought over and settled, the
prisoners, found they could not put their plan into execution - on
that day, at all events - for the _Albatross,_ after leaving Gousta,
had kept her southerly course, which took her over the North Sea,
much to the consternation of the thousands of coasting craft engaged
in the English, Dutch, French, and Belgian trade. Unless the
snuff-box fell on the deck of one of these vessels there was every
chance of its going to the bottom of the sea, and Uncle Prudent and
Phil Evans were obliged to wait for a better opportunity. And, as we
shall immediately see, an excellent chance was soon to be offered
them.

At ten o'clock that evening the _Albatross_ reached the French coast
near Dunkirk. The night was rather dark. For a moment they could see
the lighthouse at Grisnez cross its electric beam with the lights
from Dover on the other side of the strait. Then the _Albatross_ flew
over the French territory at a mean height of three thousand feet.

There was no diminution in her speed. She shot like a rocket over the
towns and villages so numerous in northern France. She was flying
straight on to Paris, and after Dunkirk came Doullens, Amiens, Creil,
Saint Denis. She never left the line; and about midnight she was over
the "city of light," which merits its name even when its inhabitants
are asleep or ought to be.

By what strange whim was it that she was stopped over the city of
Paris? We do not know; but down she came till she was within a few
hundred feet of the ground. Robur then came out of his cabin, and the
crew came on to the deck to breathe the ambient air.

Uncle Prudent and Phil Evans took care not to miss such an excellent
opportunity. They left their deck-house and walked off away from the
others so as to be ready at the propitious moment. It was important
their action should not be seen.

The _Albatross,_ like a huge coleopter, glided gently over the mighty
city. She took the line of the boulevards, then brilliantly lighted
by the Edison lamps. Up to her there floated the rumble of the
vehicles as they drove along the streets, and the roll of the trains
on the numerous railways that converge into Paris. Then she glided
over the highest monuments as if she was going to knock the ball off
the Pantheon or the cross off the Invalides. She hovered over the two
minarets of the Trocadero and the metal tower of the Champ de Mars,
where the enormous reflector was inundating the whole capital with
its electric rays.

This aerial promenade, this nocturnal loitering, lasted for about an
hour. It was a halt for breath before the voyage was resumed.

And probably Robur wished to give the Parisians the sight of a meteor
quite unforeseen by their astronomers. The lamps of the _Albatross_
were turned on. Two brilliant sheaves of light shot down and moved
along over the squares, the gardens, the palaces, the sixty thousand
houses, and swept the space from one horizon to the other.

Assuredly the _Albatross_ was seen this time - and not only well seen
but heard, for Tom Turner brought out his trumpet and blew a rousing
tarantaratara.

At this moment Uncle Prudent leant over the rail, opened his hand,
and let his snuff-box fall.

Immediately the _Albatross_ shot upwards, and past her, higher still,
there mounted the noisy cheering of the crowd then thick on the
boulevards - a hurrah of stupefaction to greet the imaginary meteor.

The lamps of the aeronef were turned off, and the darkness and the
silence closed in around as the voyage was resumed at the rate of one
hundred and twenty miles an hour.

This was all that was to be seen of the French capital. At four
o'clock in the morning the _Albatross_ had crossed the whole country
obliquely; and so as to lose no time in traversing the Alps or the
Pyrenees, she flew over the face of Provence to the cape of Antibes.
At nine o'clock next morning the San Pietrini assembled on the
terrace of St. Peter at Rome were astounded to see her pass over the
eternal city. Two hours afterwards she crossed the Bay of Naples and
hovered for an instant over the fuliginous wreaths of Vesuvius. Then,
after cutting obliquely across the Mediterranean, in the early hours
of the afternoon she was signaled by the look-outs at La Goulette on
the Tunisian coast.

After America, Asia! After Asia, Europe! More than eighteen thousand
miles had this wonderful machine accomplished in less than
twenty-three clays!

And now she was off over the known and unknown regions of Africa!

It may be interesting to know what had happened to the famous
snuff-box after its fall?

It had fallen in the Rue de Rivoli, opposite No. 200, when the street
was deserted. In the morning it was picked up by an honest sweeper,
who took it to the prefecture of police. There it was at first
supposed to be an infernal machine. And it was untied, examined, and
opened with care.

Suddenly a sort of explosion took place. It was a terrific sneeze on
the part of the inspector.

The document was then extracted from the snuff-box, and to the
general surprise, read as follows:

_"Messrs. Prudent and Evans, president and secretary of the Weldon
Institute, Philadelphia, have been carried off in the aeronef
Albatross belonging to Robur the engineer._

_"Please inform our friends and acquaintances._

_"P. and P. E."_

Thus was the strange phenomenon at last explained to the people of
the two worlds. Thus was peace given to the scientists of the
numerous observatories on the surface of the terrestrial globe.

Chapter XV

A SKIRMISH IN DAHOMEY

At this point in the circumnavigatory voyage of the _Albatross_ it is
only natural that some such questions as the following should be
asked. Who was this Robur, of whom up to the present we know nothing
but the name? Did he pass his life in the air? Did his aeronef never
rest? Had he not some retreat in some inaccessible spot in which, if
he had need of repose or revictualing, be could betake himself? It
would be very strange if it were not so. The most powerful flyers
have always an eyrie or nest somewhere.

And what was the engineer going to do with his prisoners? Was he
going to keep them in his power and condemn them to perpetual
aviation? Or was he going to take them on a trip over Africa, South
America, Australasia, the Indian Ocean, the Atlantic and the Pacific,
to convince them against their will, and then dismiss them with, "And
now gentlemen, I hope you will believe a little more in heavier than
air?"

To these questions, it is now impossible to reply. They are the
secrets of the future. Perhaps the answers will be revealed. Anyhow
the bird-like Robur was not seeking his nest on the northern frontier
of Africa. By the end of the day he had traversed Tunis from Cape Bon
to Cape Carthage, sometimes hovering, and sometimes darting along at
top speed. Soon he reached the interior, and flew down the beautiful
valley of Medjeida above its yellow stream hidden under its luxuriant
bushes of cactus and oleander; and scared away the hundreds of
parrots that perch on the telegraph wires and seem to wait for the
messages to pass to bear them away beneath their wings.

Two hours after sunset the helm was put up and the _Albatross_ bore
off to the southeast; and on the morrow, after clearing the Tell
Mountains, she saw the rising of the morning star over the sands of
the Sahara.

On the 30th of July there was seen from the aeronef the little
village of Geryville, founded like Laghouat on the frontier of the
desert to facilitate the future conquest of Kabylia. Next, not
without difficulty, the peaks of Stillero were passed against a
somewhat boisterous wind. Then the desert was crossed, sometimes
leisurely over the Ksars or green oases, sometimes at terrific speed
that far outstripped the flight of the vultures. Often the crew had
to fire into the flocks of these birds which, a dozen or so at a
time, fearlessly hurled them selves on to the aeronef to the extreme
terror of Frycollin.

But if the vultures could only reply with cries and blows of beaks
and talons, the natives, in no way less savage, were not sparing of
their musket-shots, particularly when crossing the Mountain of Sel,
whose green and violet slope bore its cape of white. Then the
_Albatross_ was at last over the grand Sahara; and at once she rose
into the higher zones so as to escape from a simoom which was
sweeping a wave of ruddy sand along the surface of the ground like a
bore on the surface of the sea.

Then the desolate tablelands of Chetka scattered their ballast in
blackish waves up to the, fresh. and verdant valley of Ain-Massin. It
is difficult to conceive the variety of the territories which could
be seen at one view. To the green hills covered with trees and shrubs
there succeeded long gray undulations draped like the folds of an
Arab burnous and broken in picturesque masses. In the distance could
be seen the wadys with their torrential waters, their forests of
palm-trees, and blocks of small houses grouped on a hill around a
mosque, among them Methlili, where there vegetates a religious chief.
the grand marabout Sidi Chick.

Before night several hundred miles had been accomplished above a
flattish country ridged occasionally with large sandhills. If the
_Albatross_ had halted, she would have come to the earth in the
depths of the Wargla oasis hidden beneath an immense forest of
palm-trees. The town was clearly enough displayed with its three
distinct quarters, the ancient palace of the Sultan, a kind of
fortified Kasbah, houses of brick which had been left to the sun to
bake, and artesian wells dug in the valley - where the aeronef could
have renewed her water supply. But, thanks to her extraordinary
speed, the waters of the Hydaspes taken in the vale of Cashmere still
filled her tanks in the center of the African desert.

Was the _Albatross_ seen by the Arabs, the Mozabites, and the Negroes
who share amongst them the town of Wargla? Certainly, for she was
saluted with many hundred gunshot, and the bullets fell back before
they reached her.

Then came the night, that silent night in the desert of which
Felicien David has so poetically told us the secrets.

During the following hours the course lay southwesterly, cutting
across the routes of El Golea, one of which was explored in 1859 by
the intrepid Duveyrier.

The darkness was profound. Nothing could be seen of the Trans -
Saharan Railway constructing on the plans of Duponchel - a long
ribbon of iron destined to bind together Algiers and Timbuktu by way
of Laghouat and Gardaia, and destined eventually to run down into the
Gulf of Guinea.

Then the _Albatross_ entered the equatorial region below the tropic
of Cancer. Six hundred miles from the northern frontier of the Sahara
she crossed the route on which Major Laing met his, death in 1846,
and crossed the road of the caravans from Morocco to the Sudan, and
that part of the desert swept by the Tuaregs, where could be heard
what is called "the song of the sand," a soft and plaintive murmur
that seems to escape from the ground.

Only one thing happened. A cloud of locusts came flying along, and
there fell such a cargo of them on board as to threaten to sink the
ship. But all hands set to work to clear the deck, and the locusts
were thrown over except a few hundred kept by Tapage for his larder.
And he served them up in so succulent a fashion that Frycollin forgot
for the moment his perpetual trances and said, "these are as good as
prawns."

The aeronef was then eleven hundred miles from the Wargla oasis and
almost on the northern frontier of the Sudan. About two o'clock in
the afternoon a city appeared in the bend of a large river. The river
was the Niger. The city was Timbuktu.

If, up to then, this African Mecca had only been visited by the
travelers of the ancient world Batouta, Khazan, Imbert, Mungo Park,
Adams, Laing, Caillй, Barth, Lenz, on that day by a most singular
chance the two Americans could boast of having seen, heard, and smelt
it, on their return to America - if they ever got back there.

Of having seen it, because their view included the whole triangle of
three or four miles in circumference; of having heard it, because the
day was one of some rejoicing and the noise was terrible; of having
smelt it, because the olfactory nerve could not but be very
disagreeably affected by the odors of the Youbou-Kamo square, where
the meatmarket stands close to the palace of the ancient Somai kings.

The engineer had no notion of allowing the president and secretary of
the Weldon Institute to be ignorant that they had the honor of
contemplating the Queen of the Sudan, now in the power of the Tuaregs
of Taganet.

"Gentlemen, Timbuktu!" he said, in the same tone as twelve days
before he had said, "Gentlemen, India!" Then he continued, "Timbuktu
is an important city of from twelve to thirteen thousand inhabitants,
formerly illustrious in science and art. Perhaps you would like to
stay there for a day or two?"

Such a proposal could only have been made ironically. "But,"
continued he, "it would he dangerous among the Negroes, Berbers, and
Foullanes who occupy, it - particularly as our arrival in an aeronef
might prejudice them against you."

"Sir," said Phil Evans, in the same tone, "for the pleasure of
leaving you we would willingly risk an unpleasant reception from the
natives. Prison for prison, we would rather be in Timbuktu than on
the _Albatross."_

"That is a matter of taste," answered the engineer. "Anyhow, I shall
not try the adventure, for I am responsible for the safety of the
guests who do me the honor to travel with me."

"And so," said Uncle Prudent, explosively, "you are not content with
being our jailer, but you insult us."

"Oh! a little irony, that is all!"

"Are there any weapons on board?"

"Oh, quite an arsenal."

"Two revolvers will do, if I hold one and you the other."

"A duel!" exclaimed Robur, "a duel, which would perhaps cause the
death of one of us."

"Which certainly would cause it."

"Well! No, Mr. President of the Weldon Institute, I very much prefer
keeping you alive."

"To be sure of living yourself. That is wise."

"Wise or not, it suits me. You are at liberty to think as you like,
and to complain to those who have the power to help you - if you can."

"And that we have done, Mr. Robur."

"Indeed!"

"Was it so difficult when we were crossing the inhabited part of
Europe to drop a letter overboard?"

"Did you do that?" said Robur, in a paroxysm of rage.

"And if we have done it?"

"If you have done it - you deserve -"

"What, sir?"

"To follow your letter overboard."

"Throw us over, then. We did do it."

Robur stepped towards them. At a gesture from him Tom Turner and some
of the crew ran up. The engineer was seriously tempted to put his
threat into execution, and, fearful perhaps of yielding to it, he
precipitately rushed into his cabin,

"Good!" exclaimed Phil Evans.

"And what he will dare not do," said Uncle Prudent, "I Will do! Yes,
I Will do!"

At the moment the population of Timbuktu were crowding onto the
squares and roads and the terraces built like amphitheaters. In the
rich quarters of Sankere and Sarahama, as in the miserable huts at
Raguidi, the priests from the minarets were thundering their loudest
maledictions against the aerial monster. These were more harmless
than the rifle-bullets; though assuredly, if the aeronef had come to
earth she would have certainly been torn to pieces.

For some miles noisy flocks of storks, francolins, and ibises
escorted the _Albatross_ and tried to race her, but in her rapid
flight she soon distanced them.

The evening came. The air was troubled by the roarings of the
numerous herds of elephants and buffaloes which wander over this
land, whose fertility is simply marvelous. For forty-eight hours the
whole of the region between the prime meridian and the second degree,
in the bend of the Niger, was viewed from the _Albatross._

If a geographer had only such an apparatus at his command, with what
facility could he map the country, note the elevations, fix the
courses of the rivers and their affluents, and determine the
positions of the towns and villages! There would then be no huge
blanks on the map of Africa, no dotted lines, no vague designations
which are the despair of cartographers.

In the morning of the 11th the _Albatross_ crossed the mountains of
northern Guinea, between the Sudan and the gulf which bears their
name. On the horizon was the confused outline of the Kong mountains
in the kingdom of Dahomey.

Since the departure from Timbuktu Uncle Prudent and Phil Evans
noticed that the course had been due south. If that direction was
persisted in they would cross the equator in six more degrees. The
_Albatross_ would then abandon the continents and fly not over the
Bering Sea, or the Caspian Sea, or the North Sea, or the
Mediterranean, but over the Atlantic Ocean.

This look-out was not particularly pleasing to the two friends, whose
chances of escape had sunk to below zero. But the _Albatross_ had
slackened speed as though hesitating to leave Africa behind. Was
Robur thinking of going back? No; but his attention had been
particularly attracted to the country which he was then crossing.

We know - and he knew - that the kingdom of Dahomey is one of the
most powerful on the West Coast of Africa. Strong enough to hold its
own with its neighbor Ashantee, its area is somewhat small, being
contained within three hundred and sixty leagues from north to south,
and one hundred and eighty from east to west. But its population
numbers some seven or eight hundred thousand, including the
neighboring independent territories of Whydah and Ardrah.

If Dahomey is not a large country, it is often talked about. It is
celebrated for the frightful cruelties which signalize its annual
festivals, and by its human sacrifices - fearful hecatombs intended
to honor the sovereign it has lost and the sovereign who has
succeeded him. It is even a matter of politeness when the King of
Dahomey receives a visit from some high personage or some foreign
ambassador to give him a surprise present of a dozen heads, cut off
in his honor by the minister of justice, the "minghan," who is
wonderfully skillful in that branch of his duties.

When the _Albatross_ came flying over Dahomey, the old King Bahadou
had just died, and the whole population was proceeding to the
enthronization of his successor. Hence there was great agitation all
over the country, and it did not escape Robur that everybody was on
the move.

Long lines of Dahomians were hurrying along the roads from the
country into the capital, Abomey. Well kept roads radiating among
vast plains clothed with giant trees, immense fields of manioc,
magnificent forests of palms, cocoa-trees, mimosas, orange-trees,
mango-trees - such was the country whose perfumes mounted to the
_Albatross,_ while many parrots and cardinals swarmed among the trees.

The engineer, leaning over the rail, seemed deep in thought, and
exchanged but a few words with Tom Turner. It did not look as though
the _Albatross_ had attracted the attention of those moving masses,
which were often invisible under the impenetrable roof of trees. This
was doubtless due to her keeping at a good altitude amid a bank of
light cloud.

About eleven o'clock in the morning the capital was sighted,
surrounded by its walls, defended by a fosse measuring twelve miles
round, with wide, regular streets on the flat plain, and a large
square on the northern side occupied by the king's palace. This huge
collection of buildings is commanded by a terrace not far from the
place of sacrifice. During the festival days it is from this high
terrace that they throw the prisoners tied up in wicker baskets, and
it can be imagined with what fury these unhappy wretches are cut in
pieces.

In one of the courtyards which divide the king's palace there were
drawn up four thousand warriors, one of the contigents of the royal
army - and not the least courageous one. If it is doubtful if there
are any Amazons an the river of that name, there is no doubt of there
being Amazons at Dahomey. Some have a blue shirt with a blue or red
scarf, with white-and-blue striped trousers and a white cap; others,
the elephant-huntresses, have a heavy carbine, a short-bladed dagger,
and two antelope horns fixed to their heads by a band of iron. The
artillery-women have a blue-and-red tunic, and, as weapons,
blunderbusses and old cast cannons; and another brigade, consisting
of vestal virgins, pure as Diana, have blue tunics and white
trousers. If we add to these Amazons, five or six thousand men in
cotton drawers and shirts, with a knotted tuft to increase their
stature, we shall have passed in review the Dahomian army.

Abomey on this day was deserted. The soveriegn, the royal family, the
masculine and feminine army, and the population had all gone out of
the capital to a vast plain a few miles away surrounded by
magnificent forests.

On this plain the recognition of the new king was to take place. Here
it was that thousands of prisoners taken during recent razzias were
to be immolated in his honor.

It was about two o'clock when the _Albatross_ arrived over the plain
and began to descend among the clouds which still hid her from the
Dahomians.

There were sixteen thousand people at least come from all parts of
the kingdom, from Whydah, and Kerapay, and Ardrah, and Tombory, and
the most distant villages.

The new king - a sturdy fellow named Bou-Nadi - some five-and-twenty
years old, was seated on a hillock shaded by a group of wide-branched
trees. Before him stood his male army, his Amazons, and his people.

At the foot of the mound fifty musicians were playing on their
barbarous instruments, elephants' tusks giving forth a husky note,
deerskin drums, calabashes, guitars, bells struck with an iron
clapper, and bamboo flutes, whose shrill whistle was heard over all.
Every other second came discharges of guns and blunderbusses,
discharges of cannons with the carriages jumpipg so as to imperil the
lives of the artillery-women, and a general uproar so intense that
even the thunder would be unheard amidst it.

In one corner of the plain, under a guard of soldiers, were grouped
the prisoners destined to accompany the defunct king into the other
world. At the obsequies of Ghozo, the father of Bahadou, his son had
dispatched three thousand, and Bou-Nadi could not do less than his
predecessor. For an hour there was a series of discourses, harangues,
palavers and dances, executed not only by professionals, but by the
Amazons, who displayed much martial grace.

But the time for the hecatomb was approaching. Robur, who knew the
customs of Dahomey, did not lose sight of the men, women, and
children reserved for butchery.

The minghan was standing at the foot of the hillock. He was
brandishing his executioner's sword, with its curved blade surmounted
by a metal bird, whose weight rendered the cut more certain.

This time he was not alone. He could not have performed the task.
Near him were grouped a hundred executioners, all accustomed to cut
off heads at one blow.

The _Albatross_ came slowly down in an oblique direction. Soon she
emerged from the bed of clouds which hid her till she was within
three hundred feet of the ground, and for the first time she was
visible from below.

Contrary to what had hitherto happened, the savages saw in her a
celestial being come to render homage to King Baha-dou. The
enthusiasm was indescribable, the shouts were interminable, the
prayers were terrific - prayers addressed to this supernatural
hippogriff, which "had doubtless come to" take the king's body to the
higher regions of the Dahomian heaven. And now the first head fell
under the minghan's sword, and the prisoners were led up in hundreds
before the horrible executioners.

Suddenly a gun was fired from the _Albatross._ The minister of
justice fell dead on his face!

"Well aimed, Tom!" said Robur,

His comrades, armed as he was, stood ready to fire when the order was
given.

But a change came over the crowd below. They had understood. The
winged monster was not a friendly spirit, it was a hostile spirit.
And after the fall of the minghan loud shouts for revenge arose on
all sides. Almost immediately a fusillade resounded over the plain.

These menaces did not prevent the _Albatross_ from descending boldly
to within a hundred and fifty feet of the ground. Uncle Prudent and
Phil Evans, whatever were their feelings towards Robur, could not
help joining him in such a work of humanity.

"Let us free the prisoners!" they shouted.

"That is what I am going to do!" said the engineer.

And the magazine rifles of the _Albatross_ in the hands of the
colleagues, as in the hands of the crew, began to rain down the
bullets, of which not one was lost in the masses below. And the
little gun shot forth its shrapnel, which really did marvels.

The prisoners, although they did not understand how the help had come
to them, broke their bonds, while the soldiers were firing at the
aeronef. The stern screw was shot through by a bullet, and a few
holes were made in the bull. Frycollin, crouching in his cabin,
received a graze from a bullet that came through the deck-house.

"Ah! They will have them!" said Tom Turner. And, rushing to the
magazine, he returned with a dozen dynamite cartridges, which be
distributed to the men. At a sign from Robur, these cartridges were
fired at the hillock, and as they reached the ground exploded like so
many small shells.

The king and his court and army and people were stricken with fear at
the turn things had taken. They fled under the trees, while the
prisoners ran off without anybody thinking of pursuing them.

In this way was the festival interfered with. And in this way did
Uncle Prudent and, Phil Evans recognize the power of the aeronef and
the services it could render to humanity.

Soon the _Albatross_ rose again to a moderate height, and passing
over Whydah lost to view this savage coast which the southwest wind
hems round with an inaccessible surf. And she flew out over the
Atlantic.

Chapter XVI

OVER THE ATLANTIC

Yes, the Atlantic! The fears of the two colleagues were realized; but
it did not seem as though Robur had the least anxiety about venturing
over this vast ocean. Both he and his men seemed quite unconcerned
about it and had gone back to their stations.

Whither was the _Albatross_ bound? Was she going more than round the
world as Robur had said? Even if she were, the voyage must end
somewhere. That Robur spent his life in the air on board the aeronef
and never came to the ground was impossible. How could he make up his
stock of provisions and the materials required for working his
machines? He must have some retreat, some harbor of refuge - in some
unknown and inaccessible spot where the _Albatross_ could revictual.
That he had broken off all connections with the inhabitants of the
land might be true, but with every point on the surface of the earth,
certainly not.

That being the case, where was this point? How had the engineer come
to choose it? Was he expected by a little colony of which he was the
chief? Could he there find a new crew?

What means had he that he should be able to build so costly a vessel
as the _Albatross_ and keep her building secret? It is true his
living was not expensive. But, finally, who was this Robur? Where did
he come from? What had been his history? Here were riddles impossible
to solve; and Robur was not the man to assist willingly in their
solution.

It is not to be wondered at that these insoluble problems drove the
colleagues almost to frenzy. To find themselves whipped off into the
unknown without knowing what the end might be doubting even if the
adventure would end, sentenced to perpetual aviation, was this not
enough to drive the President and secretary of the Weldon Institute
to extremities?

Meanwhile the _Albatross_ drove along above the Atlantic, and in the
morning when the sun rose there was nothing to be seen but the
circular line where earth met sky. Not a spot of land was insight in
this huge field of vision. Africa had vanished beneath the northern
horizon.

When Frycollin ventured out of his cabin and saw all this water
beneath him, fear took possession of him.

Of the hundred and forty-five million square miles of which the area
of the world's waters consists, the Atlantic claims about a quarter;
and it seemed as though the engineer was in no hurry to cross it.
There was now no going at full speed, none of the hundred and twenty
miles an hour at which the _Albatross_ had flown over Europe. Here,
where the southwest winds prevail, the wind was ahead of them, and
though it was not very strong, it would not do to defy it and the
_Albatross_ was sent along at a moderate speed, which, however,
easily outstripped that of the fastest mail-boat.

On the 13th of July she crossed the line, and the fact was duly
announced to the crew. It was then that Uncle Prudent and Phil Evans
ascertained that they were bound for the southern hemisphere. The
crossing of the line took place without any of the Neptunian
ceremonies that still linger on certain ships. Tapage was the only
one to mark the event, and he did so by pouring a pint of water down
Frycollin's neck.

On the 18th of July, when beyond the tropic of Capricorn, another
phenomenon was noticed, which would have been somewhat alarming to a
ship on the sea. A strange succession of luminous waves widened out
over the surface of the ocean with a speed estimated at quite sixty
miles an hour. The waves ran along at about eight feet from one
another, tracing two furrows of light. As night fell a bright
reflection rose even to the _Albatross,_ so that she might have been
taken for a flaming aerolite. Never before had Robur sailed on a sea
of fire - fire without heat - which there was no need to flee from as
it mounted upwards into the sky.

The cause cif this light must have been electricity; it could not be
attributed to a bank of fish spawn, nor to a crowd of those
animalculae that give phosphorescence to the sea, and this showed
that the electrical tension of the atmosphere was considerable.

In the morning an ordinary ship would probably have been lost. But
the _Albatross_ played with the winds and waves like the powerful
bird whose name she bore. If she did not walk on their surface like
the petrels, she could like the eagles find calm and sunshine in the
higher zones.

They had now passed the forty-seventh parallel. The day was but
little over seven hours long, and would become even less as they
approached the Pole.

About one o'clock in the afternoon the _Albatross_ was floating along
in a lower current than usual, about a hundred feet from the level of
the sea. The air was calm, but in certain parts of the sky were thick
black clouds, massed in mountains, on their upper surface, and ruled
off below by a sharp horizontal line. From these clouds a few lengthy
protuberances escaped, and their points as they fell seemed to draw
up hills of foaming water to meet them.

Suddenly the water shot up in the form of a gigantic hourglass, and
the _Albatross_ was enveloped in the eddy of an enormous waterspout,
while twenty others, black as ink, raged around her. Fortunately the
gyratory movement of the water was opposite to that of the suspensory
screws, otherwise the aeranef would have been hurled into the sea.
But she began to spin round on herself with frightful rapidity. The
danger was immense, and perhaps impossible to escape, for the
engineer could not get through the spout which sucked him back in
defiance of his propellers. The men, thrown to the ends of the deck
by centrifugal force, were grasping the rail to save themselves from
being shot off.

"Keep cool!" shouted Robur.

They wanted all their coolness, and their patience, too. Uncle
Prudent and Phil Evans, who had just come out of their cabin, were
hurled back at the risk of flying overboard. As she spun the
_Albatross_ was carried along by the spout, which pirouetted along
the waves with a speed enough to make the helices jealous. And if she
escaped from the spout she might be caught by another, and jerked to
pieces with the shock.

"Get the gun ready!" said Robur.

The order was given to Tom Turner, who was crouching behind the
swivel amidships where the effect of the centrifugal force was least
felt. He understood. In a moment he had opened the breech and slipped
a cartridge from the amunition-box at hand. The gun went off, and the
waterspouts collapsed, and with them vanished the platform of cloud
they seemed to bear above them.

"Nothing broken on board?" asked Robur.

"No," answered Tom Turner. "But we don't want to have another game of
humming-top like that!"

For ten minutes or so the _Albatross_ had been in extreme peril. Had
it not been for her extraordinary strength of build she would have
been lost.

During this passage of the Atlantic many were the hours whose
monotony was unbroken by any phenomenon whatever. The days grew
shorter and shorter, and the cold became keen. Uncle Prudent and Phil
Evans saw little of Robur. Seated in his cabin, the engineer was busy
laying out his course and marking it on his maps, taking his
observations whenever he could, recording the readings of his
barometers, thermometers, and chronometers, and making full entries
in his log-book.

The colleagues wrapped themselves well up and eagerly watched for the
sight of land to the southward. At Uncle Prudent's request Frycollin
tried to pump the cook as to whither the engineer was bound, but what
reliance could be placed on the information given by this Gascon?
Sometimes Robur was an ex-minister of the Argentine Republic,
sometimes a lord of the Admiralty, sometimes an ex-President of the
United States, sometimes a Spanish general temporarily retired,
sometimes a Viceroy of the Indies who had sought a more elevated
position in the air. Sometimes he possessed millions, thanks to
successful razzias in the aeronef, and he had been proclaimed for
piracy. Sometimes he had been ruined by making the aeronef, and had
been forced to fly aloft to escape from his creditors. As to knowing
if he were going to stop anywhere, no! But if he thought of going to
the moon, and found there a convenient anchorage, he would anchor
there! "Eh! Fry! My boy! That would just suit you to see what was
going on up there."

"I shall not go! I refuse!" said the Negro, who took all these things
seriously.

"And why, Fry, why? You might get married to some pretty bouncing
Lunarian!"

Frycollin reported this conversation to his master, who saw it was
evident that nothing was to be learnt about Robur. And so he thought
still more of how he could have his revenge on him.

"Phil," said he one day, "is it quite certain that escape is
impossible?"

"Impossible."

"Be it so! But a man is always his own property; and if necessary, by
sacrificing his life -"

"If we are to make that sacrifice," said Phil Evans, "the sooner the
better. It is almost time to end this. Where is the _Albatross_
going? Here we are flying obliquely over the Atlantic, and if we keep
on we shall get to the coast of Patagonia or Tierra del Fuego. And
what are we to do then? Get into the Pacific, or go to the continent
at the South Pole? Everything is possible with this Robur. We shall
be lost in the end. It is thus a case of legitimate self-defence, and
if we must perish -"

"Which we shall not do," answered Uncle Prudent, "without being
avenged, without annihilating this machine and all she carries."

The colleagues had reached a stage of impotent fury, and were
prepared to sacrifice themselves if they could only destroy the
inventor and his secret. A few months only would then be the life of
this prodigious aeronef, of whose superiority in aerial locomotion
they had such convincing proofs! The idea took such hold of them that
they thought of nothing else but how to put it into execution. And
how? By seizing on some of the explosives on board and simply blowing
her up. But could they get at the magazines?

Fortunately for them, Frycollin had no suspicion of their scheme. At
the thought of the _Albatross_ exploding in midair, he would not have
shrunk from betraying his master.

It was on the 23rd of July that the land reappeared in the southwest
near Cape Virgins at the entrance of the Straits of Magellan. Under
the fifty-second parallel at this time of year the night was eighteen
hours long and the temperature was six below freezing.

At first the _Albatross,_ instead of keeping on to the south,
followed the windings of the coast as if to enter the Pacific. After
passing Lomas Bay, leaving Mount Gregory to the north and the
Brecknocks to the west, they sighted Puerto Arena, a small Chilean
village, at the moment the churchbells were in full swing; and a few
hours later they were over the old settlement at Port Famine.

If the Patagonians, whose fires could be seen occasionally, were
really above the average in stature, the passengers in the aeronef
were unable to say, for to them they seemed to be dwarfs. But what a
magnificent landscape opened around during these short hours of the
southern day! Rugged mountains, peaks eternally capped with snow,
with thick forests rising on their flanks, inland seas, bays deep set
amid the peninsulas, and islands of the Archipelago. Clarence Island,
Dawson Island, and the Land of Desolation, straits and channels,
capes and promontories, all in inextricable confusion, and bound by
the ice in one solid mass from Cape Forward, the most southerly point
of the American continent, to Cape Horn the most southerly point of
the New World.

When she reached Fort Famine the _Albatross_ resumed her course to
the south. Passing between Mount Tam on the Brunswick Peninsula and
Mount Graves, she steered for Mount Sarmiento, an enormous peak
wrapped in snow, which commands the Straits of Magellan, rising six
thousand four hundred feet from the sea. And now they were over the
land of the Fuegians, Tierra del Fuego, the land of fire. Six months
later, in the height of summer, with days from fifteen to sixteen
hours long, how beautiful and fertile would most of this country be,
particularly in its northern portion! Then, all around would be seen
valleys and pasturages that could form the feeding-grounds of
thousands of animals; then would appear virgin forests, gigantic
trees-birches, beeches, ash-trees, cypresses, tree-ferns - and broad
plains overrun by herds of guanacos, vicunas, and ostriches. Now
there were armies of penguins and myriads of birds; and, when the
_Albatross_ turned on her electric lamps the guillemots, ducks, and
geese came crowding on board enough to fill Tapage's larder a hundred
times and more.

Here was work for the cook, who knew how to bring out the flavor of
the game and keep down its peculiar oiliness. And here was work for
Frycollin in plucking dozen after dozen of such interesting feathered
friends.

That day, as the sun was setting about three o'clock in the
afternoon, there appeared in sight a large lake framed in a border of
superb forest. The lake was completely frozen over, and a few natives
with long snowshoes on their feet were swiftly gliding over it.

At the sight of the _Albatross,_ the Fuegians, overwhelmed with
terror - scattered in all directions, and when they could not get
away they bid themselves, taking, like the animals, to the holes in
the ground.

The _Albatross_ still held her southerly course, crossing the Beagle
Channel, and Navarin Island and Wollaston Island, on the shores of
the Pacific. Then, having accomplished 4,700 miles since she left
Dahomey, she passed the last islands of the Magellanic archipelago,
whose most southerly outpost, lashed by the everlasting surf, is the
terrible Cape Horn.

Chapter XVII

THE SHIPWRECKED CREW

Next day was the 24th of July; and the 24th of July in the southern
hemisphere corresponds to the 24th of January in the northern. The
fifty-sixth degree of latitude had been left behind. The similar
parallel in northern Europe runs through Edinburgh.

The thermometer kept steadily below freezing, so that the machinery
was called upon to furnish a little artificial heat in the cabins.
Although the days begin to lengthen after the 21st day of June in the
southern hemisphere, yet the advance of the _Albatross_ towards the
Pole more than neutralized this increase, and consequently the
daylight became very short. There was thus very little to be seen. At
night time the cold became very keen; but as there was no scarcity of
clothing on board, the colleagues, well wrapped up, remained a good
deal on deck thinking over their plans of escape, and watching for an
opportunity. Little was seen of Robur; since the high words that had
been exchanged in the Timbuktu country, the engineer bad left off
speaking to his prisoners. Frycollin seldom came out of the
cook-house, where Tapage treated him most hospitably, on condition
that be acted as his assistant. This position was not without its
advantages, and the Negro, with his master's permission, very
willingly accepted. it. Shut up in the galley, he saw nothing of what
was passing outside, and might even consider himself beyond the reach
of danger. He was, in fact, very like the ostrich, not only in his
stomach, but in his folly.

But whither went the _Albatross?_ Was she in mid-winter bound for the
southern seas or continents round the Pole? In this icy atmosphere,
even granting that the elements of the batteries were unaffected by
such frost, would not all the crew succumb to a horrible death from
the cold? That Robur should attempt to cross the Pole in the warm
season was bad enough, but to attempt such a thing in the depth of
the winter night would be the act of a madman.

Thus reasoned the President and Secretary of the Weldon Institute,
now they had been brought to the end of the continent of the New
World, which is still America, although it does not belong to the
United States.

What was this intractable Robur going to do? Had not the time arrived
for them to end the voyage by blowing up the ship?

It was noticed that during the 24th of July the engineer had frequent
consultations with his mate. He and Tom Turner kept constant watch on
the barometer - not so much to keep themselves informed of the height
at which they were traveling as to be on the look-out for a change in
the weather. Evidently some indications had been observed of which it
was necessary to make careful note.

Uncle Prudent also remarked that Robur had been taking stock of the
provisions and stores, and everything seemed to show that he was
contemplating turning back.

"Turning back!" said Phil Evans. "But where to?"

"Where he can reprovision the ship," said Uncle Prudent.

"That ought to be in some lonely island in the Pacific with a colony
of scoundrels worthy of their chief."

"That is what I think. I fancy he is going west, and with the speed
he can get up it would not take, him long to get home."

"But we should not be able to put our plan into execution. If we get
there -"

"We shall not get there!"

The colleagues had partly guessed the engineer's intentions. During
the day it became no longer doubtful that when the _Albatross_
reached the confines of the Antarctic Sea her course was to be
changed. When the ice has formed about Cape Horn the lower regions of
the Pacific are covered with icefields and icebergs. The floes then
form an impenetrable barrier to the strongest ships and the boldest
navigators. Of course, by increasing the speed of her wings the
_Albatross_ could clear the mountains of ice accumulated on the ocean
as she could the mountains of earth on the polar continent - if it is
a continent that forms the cap of the southern pole. But would she
attempt it in the middle of the polar night, in an atmosphere of
sixty below freezing?

After she had advanced about a hundred miles to the south the
_Albatross_ headed westerly, as if for some unknown island of the
Pacific. Beneath her stretched the liquid plain between Asia and
America. The waters now had assumed that singular color which has
earned for them the name of the Milky Sea. In the half shadow, which
the enfeebled rays of the sun were unable to dissipate, the surface
of the Pacific was a milky white. It seemed like a vast snowfield,
whose undulations were imperceptible at such a height. If the sea had
been solidified by the cold, and converted into an immense icefield,
its aspect could not have been much different. They knew that the
phenomenon was produced by myriads of luminous particles of
phosphorescent corpuscles; but it was surprising to come across such
an opalescent mass beyond the limits of the Indian Ocean.

Suddenly the barometer fell after keeping somewhat high during the
earlier hours of the day. Evidently the indications were such as a
shipmaster might feel anxious at, though the master of an aeronef
might despise them. There was every sign that a terrible storm had
recently raged in the Pacific.

It was one o'clock in the afternoon when Tom Turner came up to the
engineer and said, "Do you see that black spot on the horizon, sir -
there away to due north of us? That is not a rock?"

"No, Tom; there is no land out there."

"Then it must be a ship or a boat."

Uncle Prudent and Phil Evans, who were in the bow, looked in the
direction pointed out by the mate.

Robur asked for the glass and attentively observed the object.

"It is a boat," said he, "and there are some men in it."

"Shipwrecked?" asked Tom.

"Yes! They have had to abandon their ship, and, knowing nothing of
the nearest land, are perhaps dying of hunger and thirst! Well, it
shall not be said that the _Albatross_ did not come to their help!"

The orders were given, and the aeronef began to sink towards the sea.
At three hundred yards from it the descent was stopped, and the
propellers drove ahead full speed towards the north.

It was a boat. Her sail flapped against the mast as she rose and fell
on the waves. There was no wind, and she was making no progress.
Doubtless there was no one on board with strength enough left to work
the oars. In the boat were five men asleep or helpless, if they were
not dead.

The _Albatross_ had arrived above them, and slowly descended. On the
boat's stern was the name of the ship to which she belonged - the
_Jeannette_ of Nantes.

"Hallo, there!" shouted Turner, loud enough for the men to hear, for
the boat was only eighty feet below him.

There was no answer. "Fire a gun!" said Robur.

The gun was fired and the report rang out over the sea.

One of the men looked up feebly. His eyes were haggard and his face
was that of a skeleton. As he caught sight of the _Albatross_ he made
a gesture as of fear.

"Don't be afraid," said Robur in French, "we have come to help you.
Who are you?"

"We belong to the barque _Jeannette,_ and I am the mate. We left her
a fortnight ago as she was sinking. We have no water and no food."

The four other men had now sat up. Wan and exhausted, in a terrible
state of emaciation, they lifted their hands towards the _Albatross._

"Look-out!" shouted Robur.

A line was let down, and a pail of fresh water was lowered into the
boat. The men snatched at it and drank it with an eagerness awful to
see.

"Bread, bread!" they exclaimed.

Immediately a basket with some food and five pints of coffee
descended towards them. The mate with difficulty restrained them in
their ravenousness.

"Where are we?" asked the mate at last.

"Fifty miles from the Chili coast and the Chonos Archipelago,"
answered Robur.

"Thanks. But we are becalmed, and - ?"

"We are going to tow you."

"Who are you?"

"People who are glad to be of assistance to you," said Robur.

The mate understood that the incognito was to be respected. But had
the flying machine sufficient power to tow them through the water?

Yes; and the boat, attached to a hundred feet of rope, began to move
off towards the east. At ten o'clock at night the land was sighted -
or rather they could see the lights which indicated its position.
This rescue from the sky had come just in time for the survivors of
the _Jeannette,_ and they had good reason to believe it miraculous.

When they had been taken to the mouth of the channel leading among
the Chonos Islands, Robur shouted to them to cast off the tow-line.
This, with many a blessing to those who had saved them, they did, and
the _Albatross_ headed out to the offing.

Certainly there was some good in this aeronef, which could thus help
those who were lost at sea! What balloon, perfect as it might be,
would be able to perform such a service? And between themselves Uncle
Prudent and Phil Evans could not but admire it, although they were
quite disposed to deny the evidence of their senses.

Chapter XVIII

OVER THE VOLCANO

The sea was as rough as ever, and the symptoms became alarming. The
barometer fell several millimeters. The wind came in violent gusts,
and then for a moment or so failed altogether. Under such
circumstances a sailing vessel would have had to reef in her topsails
and her foresail. Everything showed that the wind was rising in the
northwest. The storm-glass became much troubled and its movements
were most disquieting.

At one o'clock in the morning the wind came on again with extreme
violence. Although the aeronef was going right in its teeth she was
still making progress at a rate of from twelve to fifteen miles an
hour. But that was the utmost she could do.

Evidently preparations must be made for a cyclone, a very rare
occurrence in these latitudes. Whether it be called a hurricane, as
in the Atlantic, a typhoon, as in Chinese waters a simoom, as in the
Sahara, or a tornado, as on the western coast, such a storm is always
a gyratory one, and most dangerous for any ship caught in the current
which increases from the circumference to the center, and has only
one spot of calm, the middle of the vortex.

Robur knew this. He also knew it was best to escape from the cyclone
and get beyond its zone of attraction by ascending to the higher
strata. Up to then he had always succeeded in doing this, but now he
had not an hour, perhaps not a minute, to lose.

In fact the violence of the wind sensibly increased. The crests of
the waves were swept off as they rose and blown into white dust on
the surface of the sea. It was manifest that the cyclone was
advancing with fearful velocity straight towards the regions of the
pole.

"Higher!" said Robur.

"Higher it is," said Tom Tumor.

An extreme ascensional power was communicated to the aeronef, and she
shot up slantingly as if she was traveling on a plane sloping
downwards from the southwest. Suddenly the barometer fell more than a
dozen millimeters and the _Albatross_ paused in her ascent.

What was the cause of the stoppage? Evidently she was pulled back by
the air; some formidable current bad diminished the resistance to the
screws. When a steamer travels upstream more work is got out of her
screw than when the water is running between the blades. The recoil
is then considerable, and may perhaps be as great as the current. It
was thus with the _Albatross_ at this moment.

But Robur was not the man to give in. His seventy-four screws,
working perfectly together, were driven at their maximum speed. But
the aeronef could not escape; the attraction of the cyclone was
irrestible. During the few moments of calm she began to ascend, but
the heavy pull soon drew her back, and she sunk like a ship as she
founders.

Evidently if the violence of the cyclone went on increasing the
_Albatross_ would be but as a straw caught in one of those whirlwinds
that root up the trees, carry off roofs, and blow down walls.

Robur and Tom could only speak by signs. Uncle Prudent and Phil Evans
clung to the rail and wondered if the cyclone was not playing their
game in destroying the aeronef and with her the inventor - and with
the inventor the secret of his invention.

But if the _Albatross_ could not get out of the cyclone vertically
could she not do something else? Could she not gain the center, where
it was comparatively cahn, and where they would have more control
over her? Quite so, but to do this she would have to break through
the circular currents which were sweeping her round with them. Had
she sufficient mechanical power to escape through them?

Suddenly the upper part of the cloud fell in. The vapor condensed in
torrents of rain. It was two o'clock in the morning. The barometer,
oscillating over a range of twelve millimeters, had now fallen to
27.91, and from this something should be taken on account of the
height of the aeronef above the level of the sea.

Strange to say, the cyclone was out of the zone to which such storms
are generally restricted, such zone being bounded by the thirtieth
parallel of north latitude and the twenty-sixth parallel of south
latitude. This may perhaps explain why the eddying storm suddenly
turned into a straight one. But what a hurricane! The tempest in
Connecticut on the 22nd of March, 1882, could only have been compared
to it, and the speed of that was more than three hundred miles an
hour.

The _Albatross_ had thus to fly before the wind or rather she had to
be left to be driven by the current, from which she could neither
mount nor escape. But in following this unchanging trajectory she was
bearing due south, towards those polar regions which Robur had
endeavored to avoid. And now he was no longer master of her course;
she would go where the hurricane took her.

Tom Turner was at the helm, and it required all his skill to keep her
straight. In the first hours of the morning - if we can so call the
vague tint which began to rise over the horizon - the _Albatross_ was
fifteen degrees below Cape Horn; twelve hundred miles more and she
would cross the antarctic circle. Where she was, in this month of
July, the night lasted nineteen hours and a half. The sun's disk -
without warmth, without light - only appeared above the horizon to
disappear ahnost immediately. At the pole the night lengthened into
one of a hundred and seventy-nine hours. Everything showed that the
_Albatross_ was about to plunge into an abyss.

During the day an observation, had it been possible, would have given
66" 40" south latitude. The aeronef was within fourteen hundred miles
of the pole.

Irresistibly was she drawn towards this inaccessible corner of the
globe, her speed eating up, so to speak, her weight, although she
weighed less than before, owing to the flattening of the earth at the
pole. It seemed as though she could have dispensed altogether with
her suspensory screws. And soon the fury of the storm reached such a
height that Robur thought it best to reduce the speed of her helices
as much as possible, so as to avoid disaster. And only enough speed
was given to keep the aeronef under control of the rudder.

Amid these dangers the engineer retained his imperturbable coolness,
and the crew obeyed him as if their leader's mind had entered into
them. Uncle Prudent and Phil Evans had not for a moment left the
deck; they could remain without being disturbed. The air made but
slight resistance. The aeronef was like an aerostat, which drifts
with the fluid masses in which it is plunged.

Is the domain of the southern pole a continent or an archipelago? Or
is it a palaeocrystic sea, whose ice melts not even during the long
summer? We know not. But what we do know is that the southern pole is
colder than the northern one - a phenomenon due to the position of
the earth in its orbit during winter in the antarctic regions.

During this day there was nothing to show that the storm was abating.
It was by the seventy-fifth meridian to the west that the _Albatross_
crossed into the circumpolar region. By what meridian would she come
out - if she ever came out?

As she descended more to the south the length of the day diminished.
Before long she would be plunged in that continuous night which is
illuminated only by the rays of the moon or the pale streamers of the
aurora. But the moon was then new, and the companions of Robur might
see nothing of the regions whose secret has hitherto defied human
curiosity, There was not much inconvenience on board from the cold,
for the temperature, was not nearly so low as was expected.

It seemed as though the hurricane was a sort of Gulf Stream, carrying
a certain amount of heat along with it.

Great was the regret that the whole region was in such profound
obscurity. Even if the moon had been in full glory but few
observations could have been made. At this season of the year an
immense curtain of snow, an icy carapace, covers up the polar
surface. There was none of that ice "blink" to be seen, that whitish
tint of which the reflection is absent from dark horizons. Under such
circumstances, how could they distinguish the shape of the ground,
the extent of the seas, the position of the islands? How could they
recognize the hydrographic network of the country or the orographic
configuration, and distinguish the hills and mountains from the
icebergs and floes?

A little after midnight an aurora illuminated the darkness. With its
silver fringes and spangles radiating over space, it seemed like a
huge fan open over half the sky. Its farthest electric effluences
were lost in the Southern Cross, whose four bright stars were
gleaming overhead. The phenomenon was one of incomparable
magnificence, and the light showed the face of the country as a
confused mass of white.

It need not be said that they had approached so near to the pole that
the compass was constantly affected, and gave no precise indication
of the course pursued. Its inclination was such that at one time
Robur felt certain they were passing over the magnetic pole
discovered by Sir James Ross. And an hour later, in calculating the
angle the needle made with the vertical, he exclaimed: "the South
Pole is beneath us!"

A white cap appeared, but nothing could be seen of what it bid under
its ice.

A few minutes afterwards the aurora died away, and the point where
all the world's meridians cross is still to be discovered.

If Uncle Prudent and Phil Evans wished to bury in the most mysterious
solitudes the aeronef and all she bore, the moment was propitious. If
they did not do so it was doubtless because the explosive they
required was still denied to them.

The hurricane still raged and swept along with such rapidity that had
a mountain been met with the aeronef would have been dashed to pieces
like a ship on a lee shore. Not only had the power gone to steer her
horizontally, but the control of her elevation had also vanished.

And it was not unlikely that mountains did exist in these antarctic
lands. Any instant a shock might happen which would destroy the
_Albatross._ Such a catastrophe became more probable as the wind
shifted more to the east after they passed the prime meridian. Two
luminous points then showed themselves ahead of the _Albatross._
There were the two volcanos of the Ross Mountains - Erebus and
Terror. Was the _Albatross_ to be shriveled up in their flames like a
gigantic butterfly?

An hour of intense excitement followed. One of the volcanoes, Erebus,
seemed to be rushing at the aeronef, which could not move from the
bed of the hurricane. The cloud of flame grew as they neared it. A
network of fire barred their road. A brilliant light shone round over
all. The figures on board stood out in the bright light as if come
from another world. Motionless, without a sound or a gesture, they
waited for the terrible moment when the furnace would wrap them in
its fires.

But the storm that bore the _Albatross_ saved them from such a
fearful fate. The flames of Erebus were blown down by the hurricane
as it passed, and the _Albatross_ flew over unhurt. She swept through
a hail of ejected material, which was fortunately kept at bay by the
centrifugal action of the suspensory screws. And she harmlessly
passed over the crater while it was in full eruption.

An hour afterwards the horizon hid from their view the two colossal
torches which light the confines of the world during the long polar
night.

At two o'clock in the morning Balleny Island was sighted on the coast
of Discovery Land, though it could not be recognized owing to its
being bound to the mainland by a cement of ice.

And the _Albatross_ emerged from the polar circle on the hundred and
seventy-fifth meridian. The hurricane had carried her over the
icebergs and icefloes, against which she was in danger of being
dashed a hundred times or more. She was not in the hands of the
helmsman, but in the hand of God - and God is a good pilot.

The aeronef sped along to the north, and at the sixtieth parallel the
storm showed signs of dying away. Its violence sensibly diminished.
The _Albatross_ began to come under control again. And, what was a
great comfort, had again entered the lighted regions of the globe;
and the day reappeared about eight o'clock in the morning.

Robur had been carried by the storm into the Pacific over the polar
region, accomplishing four thousand three hundred and fifty miles in
nineteen hours, or about three miles a minute, a speed almost double
that which the _Albatross_ was equal to with her propellers under
ordinary circumstances. But he did not know where he then was owing
to the disturbance of the needle in the neighborhood of the magnetic
pole, and he would have to wait till the sun shone out under
convenient conditions for observation. Unfortunately, heavy clouds
covered the sky all that day and the sun did not appear.

This was a disappointment more keenly felt as both propelling screws
had sustained damage during the tempest. Robur, much disconcerted at
this accident, could only advance at a moderate speed during this
day, and when he passed over the antipodes of Paris was only going
about eighteen miles an hour. It was necessary not to aggravate the
damage to the screws, for if the propellers were rendered useless the
situation of the aeronef above the vast seas of the Pacific would be
a very awkward one. And the engineer began to consider if he could
not effect his repairs on the spot, so as to make sure of continuing
his voyage.

In the morning of the 27th of July, about seven o'clock, land was
sighted to the north. It was soon seen to be an island. But which
island was it of the thousands that dot the Pacific? However, Robur
decided to stop at it without landing. He thought, that he could
repair damages during the day and start in the evening.

The wind had died away completely and this was a favorable
circumstance for the maneuver he desired to execute. At least, if she
did not remain stationary the _Albatross_ would be carried he knew
not where.

A cable one hundred and fifty feet long with an anchor at the end was
dropped overboard. When the aeronef reached the shore of the island
the anchor dragged up the first few rocks and then got firmly fixed
between two large blocks. The cable then stretched to full length
under the influence of the suspensory screws, and the _Albatross_
remained motionless, riding like a ship in a roadstead.

It was the first time she had been fastened to the earth since she
left Philadelphia.

Chapter XIX

ANCHORED AT LAST

When the _Albatross_ was high in the air the island could be seen to
be of moderate size. But on what parallel was it situated? What
meridian ran through it? Was it an island in the Pacific, in
Australasia, or in the Indian Ocean? When the sun appeared, and Robur
had taken his observations, they would know; but although they could
not trust to the indications of the compass there was reason to think
they were in the Pacific.

At this height - one hundred and, fifty feet - the island which
measured about fifteen miles round, was like a three-pointed star in
the sea.

Off the southwest point was an islet and a range of rocks. On the
shore there were no tide-marks, and this tended to confirm Robur in
his opinion as to his position for the ebb and flow are almost
imperceptible in the Pacific.

At the northwest point there was a conical mountain about two hundred
feet high.

No natives were to be seen, but they might be on the opposite coast.
In any case, if they had perceived the aeronef, terror had made them
either hide themselves or run away. The _Albatross_ had anchored on
the southwest point of the island. Not far off, down a little creek,
a small river flowed in among the rocks. Beyond were several winding
valleys; trees of different kinds; and birds - partridges and
bustards - in great numbers. If the island was not inhabited it was
habitable. Robur might surely have landed on it; if he had not done
so it was probably because the ground was uneven and did not offer a
convenient spot to beach the aeronef.

While he was waiting for the sun the engineer began the repairs he
reckoned on completing before the day was over. The suspensory screws
were undamaged and had worked admirably amid all the violence of the
storm, which, as we have said, had considerably lightened their work.
At this moment half of them were in action, enough to keep the
_Albatross_ fixed to the shore by the taut cable. But the two
propellers had suffered, and more than Robur had thought. Their
blades would have to be adjusted and the gearing seen to by which
they received their rotatory movement.

It was the screw at the bow which was first attacked under Robur's
superintendence. It was the best to commence with, in case the
_Albatross_ had to leave before the work was finished. With only this
propeller be could easily keep a proper course.

Meanwhile Uncle Prudent and his colleague, after walking about the
deck, had sat down aft. Frycollin was strangely reassured. What a
difference! To be suspended only one hundred and fifty feet from the
ground!

The work was only interrupted for a moment while the elevation of the
sun above the horizon allowed Robur to take an horary angle, so that
at the time of its culmination he could calculate his position.

The result of the observation, taken with the greatest exactitude,
was as follows: Longitude; 176 deg. 10 min. west. Latitude, 44 deg.
25 min. south.

This point on the map answered to the position of the Chatham
Islands, and particularly of Pitt Island, one of the group.

"That is nearer than I supposed," said Robur to Tom Turner.

"How far off are we?"

"Forty-six degrees south of X Island, or two thousand eight hundred
miles."

"All the more reason to get our propellers into order," said the
mate. "We may have the wind against us this passage, and with the
little stores we have left we ought to get to X as soon as possible."

"Yes, Tom, and I hope to get under way tonight, even if I go with one
screw, and put the other to-rights on the voyage."

"Mr. Robur," said Tom "What is to be done with those two gentlemen
and their servant?"

"Do you think they would complain if they became colonists of X
Island?"

But where was this X? It was an island lost in the immensity of the
Pacific Ocean between the Equator and the Tropic of Cancer - an
island most appropriately named by Robur in this algebraic fashion.
It was in the north of the South Pacific, a long way out of the route
of inter-oceanic communication. There it was that Robur had founded
his little colony, and there the _Albatross_ rested when tired with
her flight. There she was provisioned for all her voyages. In X
Island, Robur, a man of immense wealth, had established a shipyard in
which he built his aeronef. There he could repair it, and even
rebuild it. In his warehouses were materials and provisions of all
sorts stored for the fifty inhabitants who lived on the island.

When Robur had doubled Cape Horn a few days before his intention had
been to regain X Island by crossing the Pacific obliquely. But the
cyclone had seized the _Albatross,_ and the hurricane had carried her
away to the south. In fact, he had been brought back to much the same
latitude as before, and if his propellers had not been damaged the
delay would have been of no importance.

His object was therefore to get back to X Island, but as the mate had
said, the voyage would be a long one, and the winds would probably be
against them. The mechanical power of the _Albatross_ was, however,
quite equal to taking her to her destination, and under ordinary
eircumstances she would be there in three or four days.

Hence Robur's resolve to anchor on the Chatham Islands. There was
every opportunity for repairing at least the forescrew. He had no
fear that if the wind were to rise he would be driven to the south
instead of to the north. When night came the repairs would be
finished, and he would have to maneuver so as to weigh anchor. If it
were too firmly fixed in the rocks he could cut the cable and resume
his flight towards the equator.

The crew of the _Albatross,_ knowing there was no time to lose, set
to work vigorously.

While they were busy in the bow of the aeronef, Uncle Prudent and
Phil Evans held a little conversation together which had
exceptionally important consequences.

"Phil Evans," said Uncle Prudent, "you have resolved, as I have, to
sacrifice your life?"

"Yes, like you."

"It is evident that we can expect nothing from Robur."

"Nothing."

"Well, Phil Evans, I have made up my mind. If the _Albatross_ leaves
this place tonight, the night will not pass without our having
accomplished our task. We will smash the wings of this bird of
Robur's! This night I will blow it into the air!"

"The sooner the better," said Phil Evans.

It will be seen that the two colleagues were agreed on all points
even in accepting with indifference the frightful death in store for
them. "Have you all you want?" asked Evans.

"Yes. Last night, while Robur and his people had enough to do to look
after the safety of the ship, I slipped into the magazine and got
hold of a dynamite cartridge."

"Let us set to work, Uncle Prudent."

"No. Wait till tonight. When the night comes we will go into our
cabin, and you shall see something that will surprise you."

At six o'clock the colleagues dined together as usual. Two hours
afterwards they retired to their cabin like men who wished to make up
for a sleepless night.

Neither Robur nor any of his companions had a suspicion Of the
catastrophe that threatened the _Albatross._

This was Uncle Prudent's plan. As he had said, he had stolen into the
magazine, and there had possessed himself of some powder and
cartridge like those used by Robur in Dahomey. Returning to his
cabin, he bad carefully concealed the cartridge with which he had
resolved to blow up the _Albatross_ in mid-air.

Phil Evans, screened by his cornpanion, was now examinmg the infernal
machine, which was a metallic canister containing about two pounds of
dynamite, enough to shatter the aeronef to atoms. If the explosion
did not destroy her at once, it would do so in her fall. Nothing was
easier than to place this cartridge in a corner of the cabin, so that
it would blow in the deck and tear away the framework of the hull.

But to obtain the explosion it was necessary to adjust the
fulminating cap with which the cartridge was fitted. This was the
most delicate part of the operation, for the explosion would have to
be carefully timed, so as not to occur too soon or too late.

Uncle Prudent had carefully thought over the matter. His conclusions
were as follows. As soon as the fore propeller was repaired the
aeronef would resume her course to the north, and that done Robur and
his crew would probably come aft to put the other screw into order.
The presence of these people about the cabin might interfere with his
plans, and so he had resolved to make a slow match do duty as a
time-fuse.

"When I got the cartridge," said he to Phil Evans, "I took some
gunpowder as well. With the powder I will make a fuse that will take
some time to burn, and which will lead into the fulminate. My idea is
to light it about midnight, so that the explosion will take place
about three or four o'clock in the morning."

"Well planned!" said Phil Evans.

The colleagues, as we see had arrived at such a stage as to look with
the greatest nonchalance on the awful destruction in which they were
about to perish. Their hatred against Robur an& his people had so
increased that they would sacrifice their own lives to destroy the
_Albatross_ and all she bore. The act was that of madmen, it was
horrible; but at such a pitch had they arrived after five weeks of
anger that could not vent itself, of rage that could not he gratified.

And Frycollin?" asked Phil Evans, "have we the right to dispose of
his life?"

"We shall sacrifice ours as well!" said Uncle Prudent. But it is
doubtful if Frycollin would have thought the reason sufficient.

Immediately Uncle Prudent set to work, while Evans kept watch in the
neighborhood of the cabin. The crew were all at work forward. There
was no fear of being surprised. Uncle Prudent began by rubbing a
small quantity of the powder very fine; and then, having slightly
moistened it, he wrapped it up in a piece of rag in the shape of a
match. When it was lighted he calculated it would burn about an inch
in five minutes, or a yard in three hours. The match was tried and
found to answer, and was then wound round with string and attached to
the cap of the cartridge. Uncle Prudent had all finished about ten
o'clock in the evening without having excited the least suspicion.

During the day the work on the fore screw had been actively carried
on, but it had had to be taken on board to adjust the twisted blades.
Of the piles and accumulators and the machinery that drove the ship
nothing was damaged.

When night fell Robur and his men knocked off work. The fore
propeller not been got into place, and to finish it would take
another three hours. After some conversation with Tom Turner it was
decided to give the crew a rest, and postpone what required to be
done to the next morning.

The final adjustment was a matter of extreme nicety, and the electric
lamps did not give so suitable a light for such work as the daylight.

Uncle Prudent and Phil Evans were not aware of this. They had
understood that the screw would be in place during the night, and
that the _Albatross_ would be on her way to the north.

The night was dark and moonless. Heavy clouds made the darkness
deeper. A light breeze began to rise. A few puffs came from the
southwest, but they had no effect on the _Albatross._ She remained
motionless at her anchor, and the cable stretched vertically downward
to the ground.

Uncle Prudent and his colleague, imagining they were under way again,
sat shut up in their cabin, exchanging but a few words, and listening
to the f-r-r-r-r of the suspensory screws, which drowned every other
sound on board. They were waiting till the time of action arrived.

A little before midnight Uncle Prudent said, "It is time!" Under the
berths in the cabin was a sliding box, forming a small locker, and in
this locker Uncle Prudent put the dynamite and the slow-match. In
this way the match would burn without betraying itself by its smoke
or spluttering. Uncle Prudent lighted the end and pushed back the box
under the berth with "Now let us go aft, and wait."

They then went out, and were astonished not to find the steersman at
his post.

Phil Evans leant out over the rail.

"The _Albatross_ is where she was," said he in a low voice. "The work
is not finished. They have not started!"

Uncle Prudent made a gesture of disappointment. "We shall have to put
out the match," said he.

"No," said Phil Evans, "we must escape!"

"Escape?"

"Yes! down the cable! Fifty yards is nothing!"

"Nothing, of course, Phil Evans, and we should be fools not to take
the chance now it has come."

But first they went back to the cabin and took away all they could
carry, with a view to a more or less prolonged stay on the Chatham
Islands. Then they shut the door and noiselessly crept forward,
intending to wake Frycollin and take him with them.

The darkness was intense. The clouds were racing up from the
southwest, and the aeronef was tugging at her anchor and thus
throwing the cable more and more out of the vertical. There would be
no difficulty in slipping down it.

The colleagues made their way along the deck, stopping in the shadow
of the deckhouses to listen if there was any sound. The silence was
unbroken. No light shone from the portholes. The aeronef was not only
silent; she was asleep.

Uncle Prudent was close to Frycollin's cabin when Phil Evans stopped
him. "The look-out!" he said.

A man was crouching near the deck-house. He was only half asleep. All
flight would be impossible if he were to give the alarm. Close by
were a few ropes, and pieces of rag and waste used in the work at the
screw.

An instant afterwards the man was gagged and blindfolded and lashed
to the rail unable to utter a sound or move an inch. This was done
almost without a whisper.

Uncle Prudent and Phil Evans listened. Ali was silent within the
cabins. Every one on board was asleep. They reached Frycollin's
cabin. Tapage was snoring away in a style worthy of his name, and
that promised well.

To his great surprise, Uncle Prudent had not even to push Frycollin's
door. It was open. He stepped into the doorway and looked around.
"Nobody here!" he said.

"Nobody! Where can he be?" asked Phil Evans.

They went into the bow, thinking Frycollin might perhaps be asleep in
the corner. Still they found nobody.

"Has the fellow got the start of us?" asked Uncle Prudent.

"Whether he has or not," said Phil Evans, "we can't wait any longer.
Down you go."

Without hesitation the fugitives one after the other clambered over
the side and, seizing the cable with hands and feet slipped down it
safe and sound to the ground.

Think of their joy at again treading the earth they had lost for so
long - at walking on solid ground and being no longer the playthings
of the atmosphere!

They were staring up the creek to the interior of the island when
suddenly a form rose in front of them. It was Frycollin. The Negro
had had the same idea as his master and the audacity to start without
telling him. But there was no time for recriminations, and Uncle
Prudent was in search of a refuge in some distant part of the island
when Phil Evans stopped him.

"Uncle Prudent," said he. "Here we are safe from Robur. He is doomed
like his companions to a terrible death. He deserves it, we know. But
if he would swear on his honor not to take us prisoners again -"

"The honor of such a man -"

Uncle Prudent did not finish his sentence.

There was a noise on the _Albatross._ Evidently,the alarm had been
given. The escape was discovered.

"Help! Help!" shouted somebody. It was the look-out man, who had got
rid of his gag. Hurried footsteps were heard on deck. Almost
immediately the electric lamps shot beams over a large circle.

"There they are! There they are!" shouted Tom Turner. The fugitives
were seen.

At the same instant an order was given by Robur, and the suspensory
screws being slowed, the cable was hauled in on board, and the
_Albatross_ sank towards the ground.

At this moment the voice of Phil Evans was heard shouting, "Engineer
Robur, will you give us your word of honor to leave us free on this
island?"

"Never!" said Robur. And the reply was followed by the report of a
gun, and the bullet grazed Phil's shoulder.

"Ah! The brutes!" said Uncle Prudent. Knife in hand, he rushed
towards the rocks where the anchor had fixed itself. The aeronef was
not more than fifty feet from the ground.

In a few seconds the cable was cut, and the breeze, which had
increased considerably, striking the _Albatross_ on the quarter,
carried her out over the sea.

Chapter XX

THE WRECK OF THE ALBATROSS

It was then twenty minutes after midnight. Five or six shots had been
fired from the aeronef. Uncle Prudent and Frycollim, supporting Phil
Evans, had taken shelter among the rocks. They had not been hit. For
the moment there was nothing to fear.

As the _Albatross_ drifted off from Pitt Island she rose obliquely to
nearly three thousand feet. It was necessary to increase the
ascensional power to prevent her falling into the sea.

When the look-out man had got clear of his gag and shouted, Robur and
Tom Turner had rushed up to him and torn off his bandage. The mate
had then run back to the stern cabin. It was empty! Tapage had
searched Frycollin's cabin, and that also was empty.

When he saw that the prisoners had escaped, Robur was seized with a
paroxysm of anger. The escape meant the revelation of his secret to
the world. He had not been much concerned at the document thrown
overboard while they were crossing Europe, for there were so many
chances that it would be lost in its fall; but now!"

As he grew calm, "They have escaped," said he. "Be it so! But they
cannot get away from Pitt Island, and in a day or so I will go back!
I will recapture them! And then -"

In fact, the safety of the three fugitives was by no means assured.
The _Albatross_ would be repaired, and return well in hand. Before
the day was out they might again be in the power of the engineer.

Before the day was out! But in two hours the _Albatross_ would be
annihilated! The dynamite cartridge was like a torpedo fastened to
ber hull, and would accomplish her destruction in mid-air. The breeze
freshened, and the aeronef was carried to the northeast. Although her
speed was but moderate, she would be out of sight of the Chatham
Islands before sunrise. To return against the wind she must have her
propellers going, particularly the one in the bow.

"Tom," said the engineer, "Turn the lights full on."

"Yes, Sir."

"And all hands to work."

"Yes, Sir."

There was no longer any idea of putting off the work till tomorrow.
There was now no thought of fatigue. Not one of the men of the
_Albatross_ failed to share in the feelings of his chief. Not one but
was ready to do anything to recapture the fugitives!

As soon as the screw was in place they would return to the island and
drop another anchor, and give chase to the fugitives. Then only would
they begin repairing the stern-screw; and then the aeronef could
resume her voyage across the Pacific to X Island.

It was important, above all things, that the _Albatross_ should not
be carried too far to the northeast, but unfortunately the breeze
grew stronger, and she could not head against it, or even remain
stationary. Deprived of her propellers she was an unguidable balloon.
The fugitives on the shore knew that she would have disappeared
before the explosion blew her to pieces.

Robur felt much disappointment at seeing his plans so interfered
with. Would it not take him much longer than he thought to get back
to his old anchorage?

While the work at the screw was actively pushed on, he resolved to
descend to the surface of the sea, in the hope that the wind would
there be lighter. Perhaps the _Albatross_ would be able to remain in
the neighborhood until she was again fit to work to windward.

The maneuver was instantly executed. If a passing ship had sighted
the aerial machine as she gunk through the air, with her electric
lights in full blaze, with what terror would she have been seized!

When the _Albatross_ was a few hundred feet from the waves she
stopped. Unfortunately Robur found that the breeze was stronger here
than above, and the aeronef drifted off more rapidly. He risked being
blown a long, way off to the northeast, and that would delay his
return to Pitt Island. In short, after several experiments, he found
it better to keep his ship well up in the air, and the _Albatross_
went aloft to about ten thousand feet. There, if she did not remain
stationary, the drifting was very slight. The engineer could thus
hope that by sunrise at such an altitucle he would still be in sight
of the island.

Robur did not trouble himself about the reception the fugitives might
have received from the natives - if there were any natives. That they
might help them mattered little to him. With the powers of offense
possessed by the _Albatross_ they would be promptly terrified and
dispersed. The capture of the prisoners was certain, and once he had
them again, "They will not escape from X lsland!"

About one o'clock in the morning the fore-screw was finished, and all
that had to be done was to get it back to its place. This would take
about an hour. That done, the _Albatross_ would be headed southwest
and the stern-screw could be taken in hand.

And how about the match that was burning in the deserted cabin? The
match of which more than a third was now consumed? And the spark that
was creeping along to the dynamite?

Assuredly if the men of the aeronef had not been so busy one of them
would have heard the feeble sputtering that, was going on in the
deck-house. Perhaps he would have smelt the burning powder! He would
doubtless have become uneasy! And told Tom Turner! And then they
would have looked about, and found the box and the infernal machine;
and then there would have been time to save this wonderful
_Albatross_ and all she bore!

But the men were at work in the bow, twenty yards away from the
cabin. Nothing brought them to that part of the deck; nothing called
off their attention from their work. Robur was there working with his
hands, excellent mechanic as he was. He hurried on the work, but
nothing was neglected, everything was carefully done. Was it not
necessary that he should again become absolute master of his
invention? If he did not recapture the fugitives they world get away
home. They would begin inquiring into matters. They might even
discover X Island, and there would be an end to this life, which the
men of the _Albatross_ had created for themselves, a life that seemed
superhuman and sublime.

Tom Turner came up to the engineer. It was a quarter past one. "It
seems to me, sir, that the breeze is falling, and going round to the
west."

"What does the barometer say?" asked Robur, after looking up at the
sky.

"It is almost stationary, and the clouds seem gathering below us."

"So they are, and it may be raining down at the sea; but if we keep
above the rain it makes no difference to us. It will not interfere
with the work."

"If it is raining it is not a heavy rain," said Tom. "The clouds do
not look like it, and probably the wind has dropped altogether."

"Perhaps so, but I think we had better not go down yet. Let us get
into going order as soon as we can, and then we can do as we like."

At a few minutes after two the first part of the work was finished.
The fore-screw was in its place, and the power was turned on. The
speed was gradually increased, and the _Albatross,_ heading to the
southwest, returned at moderate speed towards the Chatham Islands.

"Tom," said Robur, "It is about two hours and a half since we got
adrift. The wind has not changed all the time. I think we ought to be
over the island in an hour."

"Yes, sir. We are going about forty feet a second. We ought, to be
there about half-past three."

"All the better. It would suit us best to get back while it is dark,
and even beach the _Albatross_ if we can. Those fellows will fancy we
are a long way off to the northward, and never think of keeping a
look-out. If we have to stop a day or two on the island -"

"We'll stop, and if we have to fight an army of natives?"

"We'll fight," said Robur. "We'll fight then for our _Albatross."_

The engineer went forward to the men, who were waiting for orders.
"My lads," he said to them, "we cannot knock off yet. We must work
till day comes."

They were all ready to do so. The stern-screw had now to be treated
as the other had been. The damage was the same, a twisting from the
violence of the hurricane during the passage across the southern pole.

But to get the screw on board it seemed best to stop the progress of
the aeronef for a few minutes, and even to drive her backwards. The
engines were reversed. The aeronef began to fall astern, when Tom
Turner was surprised by a peculiar odor.

This was from the gas given off by the match, which had accumulated
in the box, and was now escaping from the cabin. "Hallo!" said the
mate, with a sniff.

"What is the matter?" asked Robur.

"Don't you smell something? Isn't it burning powder?"

"So it is, Tom."

"And it comes from that cabin."

Yes, the very cabin -"

"Have those scoundrels set it on fire?"

"Suppose it is something else!" exclaimed Robur. "Force the door,
Tom; drive in the door!"

But the mate had not made one step towards it when a fearful
explosion shook the _Albatross._ The cabins flew into splinters. The
lamps went out. The electric current suddenly failed. The darkness
was complete. Most of the suspensory screws were twisted or broken,
but a few in the bow still revolved.

At the same instant the hull of the aeronef opened just behind the
first deck-house, where the engines for the fore-screw were placed;
and the after-part of the deck collapsed in space.

Immediately the last suspensory screw stopped spinning, and the
_Albatross_ dropped into the abyss.

It was a fall of ten thousand feet for the eight men who were
clinging to the wreck; and the fall was even faster than it might
have been, for the fore propeller was vertical in the air and still
working!

It was then that Robur, with extraordinary coolness, climbed up to
the broken deck-house, and seizing the lever reversed the rotation,
so that the propeller became a suspender. The fall continued, but it
was checked, and the wreck did not fall with the accelerating
swiftness of bodies influenced solely by gravitation; and if it was
death to the survivors of the _Albatross_ from their being hurled
into the sea, it was not death by asphyxia amid air which the
rapidity of descent rendered unbreathable.

Eighty seconds after the explosion, all that remained of the
_Albatross_ plunged into the waves!

Chapter XXI

THE INSTITUTE AGAIN

Some weeks before, on the 13th of June, on the morning after the
sitting during which the Weldon Institute had been given over to such
stormy discussions, the excitement of all classes of the Philadelphia
population, black or white, had been much easier to imagine than to
describe.

From a very early hour conversation was entirely occupied with the
unexpected and scandalous incident of the night before. A stranger
calling himself an engineer, and answering to the name of Robur, a
person of unknown origin, of anonymous nationality, had unexpectedly
presented himself in the club-room, insulted the balloonists, made
fun of the aeronauts, boasted of the marvels of machines heavier than
air, and raised a frightful tumult by the remarks with which he
greeted the menaces of his adversaries. After leaving the desk, amid
a volley of revolver shots, he had disappeared, and in spite of every
endeavor, no trace could be found of him.

Assuredly here was enough to exercise every tongue and excite every
imagination. But by how much was this excitement increased when in
the evening of the 13th of June it was found that neither the
president nor secretary of the Weldon Institute had returned to their
homes! Was it by chance only that they were absent? No, or at least
there was nothing to lead people to think so. It had even been agreed
that in the morning they would be back at the club, one as president,
the other as secretary, to take their places during a discussion on
the events of the-preceding evening.

And not only was there the complete disappearance of these two
considerable personages in the state of Pennsylvania, but there was
no news of the valet Frycollin. He was as undiscoverable as his
master. Never had a Negro since Toussaint L'Ouverture, Soulouque, or
Dessaline had so much talked about him.

The next day there was no news. Neither the colleagues nor Frycollin
had been found. The anxiety became serious. Agitation commenced. A
numerous crowd beseiged the post and telegraph offices in case any
news should be received. There was no news.

And they had been seen coming out of the Weldon Institute loudly
talking together, and with Frycollin in attendance, go down Walnut
Street towards Fairmount Park! Jem Chip, the vegetarian, had even
shaken hands with the president and left him with "Tomorrow!"

And William T. Forbes, the manufacturer of sugar from rags, had
received a cordial shake from Phil Evans who had said to him twice,
"Au revoir! Au revoir!"

Miss Doll and Miss Mat Forbes, so attached to Uncle Prudent by the
bonds of purest friendship, could not get over the disappearance, and
in order to obtain news of the absent, talked even more than they
were accustomed to.

Three, four, five, six days passed. Then a week, then two weeks, and
there was nothing to give a clue to the missing three. The most
minute search had been made in every quarter. Nothing! In the park,
even under the trees and brushwood. Nothing! Always nothing! Although
here it was noticed that the grass looked to be pressed down in a way
that seemed suspicious and certainly was inexplicable; and at the
edge of the clearing there were traces of a recent struggle. Perhaps
a band of scoundrels had attacked the colleagues here in the deserted
park in the middle of the night!

It was possible. The police proceeded with their inquiries in all due
form and with all lawful slowness. They dragged the Schuyllkill
river, and cut into the thick bushes that fringe its banks; and if
this was useless it was not quite a waste, for the Schuyllikll is in
great want of a good weeding, and it got it on this occasion.
Practical people are the authorities of Philadelphia!

Then the newspapers were tried. Advertisements and notices and
articles were sent to all the journals in the Union without
distinction of color. The _Daily Negro,_ the special organ of the
black race, published a portrait of Frycollin after his latest
photograph. Rewards were offered to whoever would give news of the
three absentees, and even to those who would find some clue to put
the police on the track. "Five thousand dollars! Five thousand
dollars to any citizen who would -"

Nothing was done. The five thousand dollars remained with the
treasurer of the Weldon Institute.

Undiscoverable! Undiscoverable! Undiscoverable! Uncle Prudent and
Phil Evans, of Philadelphia!

It need hardly be said that the club was put to serious inconvenience
by this disappearance of its president and secretary. And at first
the assembly voted urgency to a measure which suspended the work on
the _Go-Ahead._ How, in the absence of the principal promoters of the
affair, of those who had devoted to the enterprise a certain part of
their fortune in time and money - how could they finish the work when
these were not present? It were better, then, to wait.

And just then came the first news of the strange phenomenon which had
exercised people's rainds some weeks before. The mysterious object
had been again seen at different times in the higher regions of the
atmosphere. But nobody dreamt of establishing a connection between
this singular reappearance and the no less singular disappearance of
the members of the Weldon Institute. In fact, it would have required
a very sftong dose of imagination to connect one of these facts with
the other.

Whatever it might be, asteroid or aerolite or aerial monster, it had
reappeared in such a way that its dimensions and shape could be much
better appreciated, first in Canada, over the country between Ottawa
and Quebec, on the very morning after the disappearance of the
colleagues, and later over the plains of the Far West, where it had
tried its speed against an express train on the Union Pacific.

At the end of this day the doubts of the learned world were at an
end. The body was not a product of nature, it was a flying machine,
the practical application of the theory of "heavier than air." And if
the inventor of the aeronef had wished to keep himself unknown he
could evidently have done better than to try it over the Far West. As
to the mechanical force he required, or the engines by which it was
communicated, nothing was known, but there could be no doubt the
aeronef was gifted with an extraordinary faculty of locomotion. In
fact, a few days afterwards it was reported from the Celestial
Empire, then from the southern part of India, then from the Russian
steppes.

Who was then this bold mechanician that possessed such powers of
locomotion, for whom States had no frontiers and oceans no limits,
who disposed of the terrestrial atmosphere as if it were his domain?
Could it be this Robur whose theories had been so brutally thrown in
the face of the Weldon Institute the day he led the attack against
the utopia of guidable balloons? Perhaps such a notion occurred to
some of the wide-awake people, but none dreamt that the said Robur
had anything to do with the disappearance of the president and
secretary of the Institute.

Things remained in this state of mystery when a telegram arrived from
France through the New York cable at 11-37 A.M. on July 13. And what
was this telegram? It was the text of the document found at Paris in
a snuff-box revealing what had happened to the two personages for
whom the Union was in mourning.

So, then, the perpetrator of this kidnapping _was_ Robur the
engineer, come expressly to Philadelphia to destroy in its egg the
theory of the balloonists. He it was who commanded the _Albatross!_
He it was who carried off by way of reprisal Uncle Prudent, Phil
Evans and Frycollin; and they might be considered lost for ever. At
least until some means were found of constructing an engine capable
of contending with this powerful machine their terrestrial friends
would never bring them back to earth.

What excitement! What stupor! The telegram from Paris had been
addressed to the members of the Weldon Institute. The members of the
club were immediately informed of it. Ten minutes later all
Philadelphia received the news through its telephones, and in less
than an hour all America heard of it through the innumerable electric
wires of the new continent.

No one would believe it! "It is an unseasonable joke," said some. "It
is all smoke," said others. How could such a thing be done in
Philadelphia, and so secretly, too? How could the _Albatross_ have
been beached in Fairmount Park without its appearance having been
signaled all over Pennsylvania?

Very good. These were the arguments. The incredulous had the right of
doubting. But the right did not last long. Seven days after the
receipt of the telegram the French mail-boat Normandie came into the
Hudson, bringing the famous snuff-box. The railway took it in all
haste from New York to Philadelphia.

It was indeed the snuff-box of the President of the Weldon Institute.
Jem Chip would have done on at day to take some more substantial
nourishment, for he fell into a swoon when he recognized it. How many
a time had he taken from it the pinch of friendship! And Miss Doll
and Miss Mat also recognized it, and so did William T. Forbes, Truck
Milnor, Bat T. Fynn, and many other members. And not only was it the
president's snuff-box, it was the president's writing!

Then did the people lament and stretch out their hands in despair to
the skies. Uncle Prudent and his colleague carried away in a flying
machine, and no one able to deliver them!

The Niagara Falls Company, in which Uncle Prudent was the largest
shareholder, thought of suspending its business and turning off its
cataracts. The Wheelton Watch Company thought of winding up its
machinery, now it had lost its manager.

Nothing more was heard of the aeronef. July passed, and there was no
news. August ran its course, and the uncertainty on the subject of
Robur's prisoners was as great as ever. Had he, like Icarus, fallen a
victim to his own temerity?

The first twenty-seven days of September went by without result, but
on the 28th a rumor spread through Philadelphia that Uncle Prudent
and Phil Evans had during the afternoon quietly walked into the
president's house. And, what was more extraordinary, the rumor was
true, although very few believed it.

They had, however, to give in to the evidence. There could be no
doubt these were the two men, and not their shadows. And Frycollin
also had come back! The members of the club, then their friends, then
the crowd, swarmed into the president's house, and shook hands with
the president and secretary, and cheered them again and again. Jem
Chip was there, having left his luncheons joint of boiled lettuces,
and William T. Forbes and his daughters, and all the members of the
club. It is a mystery how Uncle Prudent and Phil Evans emerged alive
from the thousands who welcomed them.

On that evening was the weekly meeting of the Institute. It was
expected that the colleagues would take their places at the desk. As
they had said nothing of their adventures, it was thought they would
then speak, and relate the impressions of their voyage. But for some
reason or other both were silent. And so also was Frycollin, whom his
congeners in their delirium had failed to dismember.

But though the colleagues did not tell what had happened to them,
that is no reason why we should not. We know what occurred on the
night of the 27th and 28th of July; the daring escape to the earth,
the scramble among the rocks, the bullet fired at Phil Evans, the cut
cable, and the _Albatross_ deprived of her propellers, drifting off
to the northeast at a great altitude. Her electric lamps rendered her
visible for some time. And then she disappeared.

The fugitives had little to fear. Now could Robur get back to the
island for three or four hours if his screws were out of gear? By
that time the _Albatross_ would have been destroyed by the explosion,
and be no more than a wreck floating on the sea; those whom she bore
would be mangled corpses, which the ocean would not even give up
again. The act of vengeance would be accomplished.

Uncle Prudent and Phil Evans looked upon it as an act of legitimate
self-defence, and felt no remorse whatever. Evans was but slightly
wounded by the rifle bullet, and the three made their way up from the
shore in the hope of meeting some of the natives. The hope was
realized. About fifty natives were living by fishing off the western
coast. They had seen the aeronef descend on the island, and they
welcomed the fugitives as if they were supernatural beings. They
worshipped them, we ought rather to say. They accommodated them in
the most comfortable of their huts.

As they had expected, Uncle Prudent and Phil Evans saw nothing more
of the aeronef. They concluded that the catastrophe had taken place
in some high region of the atmosphere, and that they would hear no
more of Robur and his prodigious machine.

Meanwhile they had to wait for an opportunity of returning to
America. The Chatham Islands are not much visited by navigators, and
all August passed without sign of a ship. The fugitives began to ask
themselves if they had not exchanged one prison for another.

At last a ship came to water at the Chatham Islands. It will not have
been forgotten that when Uncle Prudent was seized he had on him
several thousand paper dollars, much more than would take him back to
America. After thanking their adorers, who were not sparing of their
most respectful demonstrations, Uncle Prudent, Phil Evans, and
Frycollin embarked for Auckland. They said nothing of their
adventures, and in two weeks landed in New Zealand.

At Auckland, a mail-boat took them on board as passengers, and after
a splendid passage the survivors of the _Albatross_ stepped ashore at
San Francisco. They said nothing as to who they were or whence they
had come, but as they had paid full price for their berths no
American captain would trouble them further. At San Francisco they
took the first train out on the Pacific Railway, and on the 27th of
September, they arrived at Philadelphia, That is the compendious
history of what had occurred since the, escape of the fugitives. And
that is why this very evening the president and secretary of the
Weldon Institute took their seats amid a most extraordinary
attendance.

Never before had either of them been so calm. To look at them it did
not seem as though anything abnormal had happened since the memorable
sitting of the 12th of June. Three months and a half had gone, and
seemed to be counted as nothing. After the first round of cheers,
which both received without showing the slightest emotion, Uncle
Prudent took off his hat and spoke.

"Worthy citizens," said he, "The meeting is now open."

Tremendous applause. And properly so, for if it was not extraordinary
that the meeting was open, it was extraordinary that it should be
opened by Uncle Prudent and Phil Evans.

The president allowed the enthusiasm to subside in shouts and
clappings; then he continued: "At our last meeting, gentlemen, the
discussion was somewhat animated - (hear, hear) - between the
partisans of the screw before and those of the screw behind for our
balloon the _Go-Ahead._ (Marks of sur prise.) We have found a way to
bring the beforists and the behindists in agreement. That way is as
follows: we are going to use two screws, one at each end of the
carl." Silence, and complete stupefaction.

That was all.

Yes, all! Of the kidnapping of the president and secretary of the
Weldon Institute not a word! Not a word of the _Albatross_ nor of
Robur! Not a word of the voyage! Not a word of the way in which the
prisoners had escaped! Not a word of what had become of the aeronef,
if it still flew through space, or if they were to be prepared for
new reprisals on the member's of the club!

Of course the balloonists were longing to ask Uncle Prudent and the
secretary about all these things, but they looked so close and so
serious that they thought it best to respect their attitude. When
they thought fit to speak they would do so, and it would be an honor
to hear. After all, there might be in all this some secret which
would not yet be divulged.

And then Uncle Prudent, resuming his speech amid a silence up to then
unknown in the meetings of the Weldon Institute, said, "Gentlemen, it
now only remains for us to finish the aerostat _Go-Ahead._ it is left
to her to effect the conquest of the air! The meeting is at an end!"

Chapter XXII

THE GO-AHEAD IS LAUNCHED

On the following 19th of April, seven months after the unexpected
return of Uncle Prudent and Phil Evans, Philadelphia was in a state
of unwonted excitement. There were neither elections nor meetings
this time. The aerostat _Go-Ahead,_ built by the Weldon Institute,
was to take possession of her natural element.

The celebrated Harry W. Tinder, whose name we mentioned at the
beginning of this story, had been engaged as aeronaut. He had no
assistant, and the only passengers were to be the president and
secretary of the Weldon Institute.

Did they not merit such an honor? Did it not come to them
appropriately to rise in person to protest against any apparatus that
was heavier than air?

During the seven months, however, they had said nothing of their
adventures; and even Frycollin had not uttered a whisper of Robur and
his wonderful clipper. Probably Uncle Prudent and his friend desired
that no question should arise as to the merits of the aeronef, or any
other flying machine.

Although the _Go-Ahead_ might not claim the first place among aerial
locomotives, they would have nothing to say about the. inventions of
other aviators. They believed, and would always believe, that the
true atmospheric vehicle was the aerostat, and that to it alone
belonged the future.

Besides, he on whom they had been so terribly - and in their idea so
justly - avenged, existed no longer. None of those who accompanied
him had survived. The secret of the _Albatross_ was buried in the
depths of the Pacific!

That Robur had a retreat, an island in the middle of that vast ocean,
where he could put into port, was only a hypothesis; and the
colleagues reserved to themselves the right of making inquiries on
the subject later on. The grand experiment which the Weldon Institute
had been preparing for so long was at last to take place. The
_Go-Ahead_ was the most perfect type of what had up to then been
invented in aerostatic art - she was what an _Inflexible_ or a
_Formidable_ is in ships of war.

She possessed all the qualities of a good aerostat. Her dimensions
allowed of her rising to the greatest height a balloon could attain;
her impermeability enabled her to remain for an indefinite time in
the atmosphere; her solidity would defy any dilation of gas or
violence of wind or rain; her capacity gave her sufficient
ascensional force to lift with all their accessories an electric
engine that would communicate to her propellers a power superior to
anything yet obtained. The _Go-Ahead_ was of elongated form, so as to
facilitate her horizontal displacement. Her car was a platform
somewhat like that of the balloon used by Krebs and Renard; and it
carried all the necessary outfit, instruments, cables, grapnels,
guide-ropes, etc., and the piles and accumulators for the mechanical
power. The car had a screw in front, and a screw and rudder behind.
But probably the work done by the machines would be very much less
than that done by the machines of the _Albatross._

The _Go-Ahead_ had been taken to the clearing in Fairmount Park, to
the very spot where the aeronef had landed for a few hours.

Her ascensional power was due to the very lightest of gaseous bodies.
Ordinary lighting gas possesses an elevating force of about 700 grams
for every cubic meter. But hydrogen possesses an ascensional force
estimated at 1,100 grams per cubic meter. Pure hydrogen prepared
according to the method of the celebrated Henry Gifford filled the
enormous balloon. And as the capacity of the _Go-Ahead_ was 40,000
cubic meters, the asdensional power of the gas she contained was
40,000 multiplied by 1,100 or 44,000 kilograms.

On this 29th of April everything was ready. Since eleven o'clock the
enormous aerostat had been floating a few feet from the ground ready
to rise in mid-air. It was splendid weather and seemed to have been
made specially for the experiment, although if the breeze had been
stronger the results might have been more conclusive. There had never
been any doubt that a balloon could he guided in a calm atmosphere;
but to guide it when the atmosphere is in motion is quite another
thing; and it is under such circumstances that the experiment should
be tried.

But there was no wind today, nor any sign of any. Strange to say,
North America on that day omitted to send on to Europe one of those
first-class storms which it seems to have in such inexhaustible
numbers. A better day could not have been chosen for an aeronautic
experiment.

The crowd was immense in Fairmount Park; trains had poured into the
Pennsylvania capital sightseers from the neighboring states;
industrial and commercial life came to a standstill that the people
might troop to the show-master, workmen, women, old men, children,
members of Congress, soldiers, magistrates, reporters, white natives
and black natives, all were there. We need not stop to describe the
excitement, the unaccountable movements, the sudden pushings, which
made the mass heave and swell. Nor need we recount the number of
cheers which rose from all sides like fireworks when Uncle Prudent
and Phil Evans appeared on the platform and hoisted the American
colors. Need we say that the majority of the crowd had come from afar
not so much to see the _Go-Ahead_ as to gaze on these extraordinary
men?

Why two and not three? Why not Frycollin? Because Frycollin thought
his campaign in the _Albatross_ sufficient for his fame. He had
declined the honor of accompanying his master, and he took no part in
the frenzied declamations that greeted the president and secretary of
the Weldon Institute.

Of the members of the illustrious assembly not one was absent from
the reserved places within the ropes. There were Truck Milnor, Bat T.
Fynn, and William T. Forbes with his two daughters on his arm. All
had come to affirm by their presence that nothing could separate them
from the partisans of "lighter than air."

About twenty minutes past eleven a gun announced the end of the final
preparations. The _Go-Ahead_ only waited the signal to start. At
twenty-five minutes past eleven the second gun was fired.

The _Go-Ahead_ was about one hundred and fifty feet above the
clearing, and was held by a rope. In this way the platform commanded
the excited crowd. Uncle Prudent and Phil Evans stood upright and
placed their left hands on their hearts, to signify how deeply they
were touched by their reception. Then they extended their right hands
towards the zenith, to signify that the greatest of known balloons
was about to take possession of the supra-terrestrial domain.

A hundred thousand hands were placed in answer on a hundred thousand
hearts, and a hundred thousand other hands were lifted to the sky.

The third gun was fired at half-past eleven. "Let go!" shouted Uncle
Prudent; and the _Go-Ahead_ rose "majestically" - an adverb
consecrated by custom to all aerostatic ascents.

It really was a superb spectacle. It seemed as if a vessel were just
launched from the stocks. And was she not a vessel launched into the
aerial sea? The _Go-Ahead_ went up in a perfectly vertical line - a
proof of the calmness of the atmosphere - and stopped at an altitude
of eight hundred feet.

Then she began her horizontal maneuvering. With her screws going she
moved to the east at a speed of twelve yards a second. That is the
speed of the whale - not an inappropriate comparison, for the balloon
was somewhat of the shape of the giant of the northern seas.

A salvo of cheers mounted towards the skillful aeronauts. Then under
the influence of her rudder, the _Go-Ahead_ went through all the
evolutions that her steersman could give her. She turned in a small
circle; she moved forwards and backwards in a way to convince the
most refractory disbeliever in the guiding of balloons. And if there
had been any disbeliever there he would have been simply annihilated.

But why was there no wind to assist at this magnificent experiment?
It was regrettable. Doubtless the spectators would have seen the
_Go-Ahead_ unhesitatingly execute all the movements of a
sailing-vessel in beating to windward, or of a steamer driving in the
wind's eye.

At this moment the acrostat rose a few hundred yards. The maneuver
was understood below. Uncle Prudent and his companions were going in
search of a breeze in the higher zones, so as to complete the
experiment. The system of cellular balloons - analogous to the
swimming bladder in fishes - into which could be introduced a certain
amount of air by pumping, had provided for this vertical motion.
Without throwing out ballast or losing gas the aeronaut was able to
rise or sink at his will. Of course there was a valve in the upper
hemisphere which would permit of a rapid descent if found necessary.
All these contrivances are well known, but they were here fitted in
perfection.

The _Go-Ahead_ then rose vertically. Her enormous dimensions
gradually grew smaller to the eye, and the necks of the crowd were
almost cricked as they gazed into the air. Gradually the whale became
a porpoise, and the porpoise became a gudgeon. The ascensional
movement did not cease until the _Go-Ahead_ had reached a height of
fourteen thousand feet. But the air was so free from mist that she
remained clearly visible.

However, she remained over the clearing as if she were a fixture. An
immense bell had imprisoned the atmosphere and deprived it of
movement; not a breath of wind was there, high or low. The aerostat
maneuvered without encountering any resistance, seeming very small
owing to the distance, much as if she were being looked at through
the wrong end of a telescope.

Suddenly there was a shout among the crowd, a shout followed by a
hundred thousand more. AU hands were stretched towards a point on the
horizon. That point was the northwest. There in the deep azure
appeared a moving body, which was approaching and growing larger. Was
it a bird beating with its wings the higher zones of space? Was it an
aerolite shooting obliquely through the atmosphere? In any case, its
speed was terrific, and it would soon be above the crowd. A suspicion
communicated itself electrically to the brains of all on the clearing.

But it seemed as though the _Go-Ahead_ had sighted this strange
object. Assuredly it seemed as though she feared some danger, for her
speed was increased, and she was going east as fast as she could.

Yes, the crowd saw what it meant! A name uttered by one of the
members of the Weldon Institute was repeated by a hundred thousand
mouths:

"The _Albatross!_ The _Albatross!"_

Chapter XXIII

THE GRAND COLLAPSE

It was indeed the _Albatross!_ It was indeed Robur who had reappeared
in the heights of the sky! It was he who like a huge bird of prey was
going to strike the _Go-Ahead._

And yet, nine months before, the aeronef, shattered by the explosion,
her screws broken, her deck smashed in two, had been apparently
annihilated.

Without the prodigious coolness of the engineer, who reversed the
gyratory motion of the fore propeller and converted it into a
suspensory screw, the men of the _Albatross_ would all have been
asphyxiated by the fall. But if they had escaped asphyxia, how had
they escaped being drowned in the Pacific?

The remains of the deck, the blades of the propellers, the
compartments of the cabins, all formed a sort of raft. When a wounded
bird falls on the waves its wings keep it afloat. For several hours
Robur and his men remained unhelped, at first on the wreck, and
afterwards in the india-rubber boat that had fallen uninjured. A few
hours after sunrise they were sighted by a passing ship, and a boat
was lowered to their rescue.

Robur and his companions were saved, and so was much of what remained
of the aeronef. The engineer said that his ship had perished in a
collision, and no further questions were asked him.

The ship was an English three-master, the _Two Friends,_ bound for
Melbourne, where she arrived a few days afterwards.

Robur was in Australia, but a long way from X Island, to which he
desired to return as soon as possible.

In the ruins of the aftermost cabin he had found a considerable sum
of money, quite enough to provide for himself and companions without
applying to anyone for help. A short time after he arrived in
Melbourne he became the owner of a small brigantine of about a
hundred tons, and in her he sailed for X Island.

There he had but one idea - to be avenged. But to secure his
vengeance he would have to make another _Albatross._ This after all
was an easy task for him who made the first. He used up what he could
of the old material; the propellers and engines he had brought back
in the brigantine. The mechanism was fitted with new piles and new
accumulators, and, in short, in less than eight months, the work was
finished, and a new _Albatross,_ identical with the one destroyed by
the explosion, was ready to take flight. And he had the same crew.

The _Albatross_ left X Island in the first week of April. During this
aerial passage Robur did not want to be seen from the earth, and he
came along almost always above the clouds. When he arrived over North
America he descended in a desolate spot in the Far West. There the
engineer, keeping a profound incognito, learnt with considerable
pleasure that the Weldon Institute was about to begin its
experiments, and that the _Go-Ahead,_ with Uncle Prudent and Phil
Evans, was going to start from Philadelphia on the 29th of April.

Here was a chance for Robur and his crew to gratify their longing for
revenge. Here was a chance for inflicting on their foes a terrible
vengeance, which in the _Go-Ahead_ they could not escape. A public
vengeance, which would at the same time prove the superiority of the
aeronef to all aerostats and contrivances of that nature!

And that is why, on this very day, like a vulture from the clouds,
the aeronef appeared over Fairmount Park.

Yes! It was the _Albatross,_ easily recognizable by all those who had
never before seen her.

The _Go-Ahead_ was in full flight; but it soon appeared that she
could not escape horizontally, and so she sought her safety in a
vertical direction, not dropping to the ground, for the aeronef would
have cut her off, but rising to a zone where she could not perhaps be
reached. This was very daring, and at the same time very logical.

But the _Albatross_ began to rise after her. Although she was smaller
than the _Go-Ahead,_ it was a case of the swordfish and the whale.

This could easily be seen from below and with what anxiety! In a few
moments the aerostat had attained a height of sixteen thousand feet.

The _Albatross_ followed her as she rose. She flew round her flanks,
and maneuvered round her in a circle with a constantly diminishing
radius. She could have annihilated her at a stroke, and Uncle Prudent
and his companions would have been dashed to atoms in a frightful
fall.

The people, mute with horror, gazed breathlessly; they were seized
with that sort of fear which presses on the chest and grips the legs
when we see anyone fall from a height. An aerial combat was beginning
in which there were none of the chances of safety as in a sea-fight.
It was the first of its kind, but it would not be the last, for
progress is one of the laws of this world. And if the _Go-Ahead_ was
flying the American colors, did not the _Albatross_ display the stars
and golden sun of Robur the Conqueror? i The _Go-Ahead_ tried to
distance her enemy by rising still higher. She threw away the ballast
she had in reserve; she made a new leap of three thousand feet; she
was now but a dot in space. The _Albatross,_ which followed her round
and round at top speed, was now invisible.

Suddenly a shout of terror rose from the crowd. The _Go-Ahead_
increased rapidly in size, and the aeronef appeared dropping with
her. This time it was a fall. The gas had dilated in the higher zones
of the atmosphere and had burst the balloon, which, half inflated
still, was falling rapidly.

But the aeronef, slowing her suspensory screws, came down just as
fast. She ran alongside the _Go-Ahead_ when she was not more than
four thousand feet from the ground.

Would Robur destroy her?

No; he was going to save her crew!

And so cleverly did he handle his vessel that the aeronaut jumped on
board.

Would Uncle Prudent and Phil Evans refuse to be saved by him? They
were quite capable of doing so. But the crew threw themselves on them
and dragged them by force from the _Go-Ahead_ to the _Albatross._

Then the aeronef glided off and remained stationary, while the
balloon, quite empty of gas, fell on the trees of the clearing and
hung there like a gigantic rag.

An appalling silence reigned on the ground. It seemed as though life
were suspended in each of the crowd; and many eyes had been closed so
as not to behold the final catastrophe. Uncle Prudent and Phil Evans
had again become the prisoners of the redoubtable Robur. Now he had
recaptured them, would he carry them off into space, where it was
impossible to follow him?

It seemed so.

However, instead of mounting into the sky the _Albatross_ stopped six
feet from the ground. Then, amid profound silence, the engineer's
voice was heard.

"Citizens of the United States," he said, "The president and
secretary of the Weldon Institute are again in my power. In keeping
them I am only within my right. But from the passion kindled in them
by the success of the _Albatross_ I see that their minds are not
prepared for that important revolution which the conquest of the air
will one day bring, Uncle Prudent and Phil Evans, you are free!"

The president, the secretary, and the aeronaut had only to jump down.

Then Robur continued.

"Citizens of the United States, my experiment is finished; but my
advice to those present is to be premature in nothing, not even in
progress. It is evolution and not revolution that we should seek. In
a word, we must not be before our time. I have come too soon today to
withstand such contradictory and divided interests as yours. Nations
are not yet fit for union.

"I go, then; and I take my secret with me. But it will not be lost to
humanity. It will belong to you the day you are educated enough to
profit by it and wise enough not to abuse it. Citizens of the United
States - Good-by!"

And the _Albatross,_ beating the air with her seventy-four screws,
and driven by her propellers, shot off towards the east amid a
tempest of cheers.

The two colleagues, profoundly humiliated, and through them the whole
Weldon Institute, did the only thing they could. They went home.

And the crowd by a sudden change of front greeted them with
particularly keen sarcasms, and, at their expense, are sarcastic
still.

And now, who is this Robur? Shall we ever know?

We know today. Robur is the science of the future. Perhaps the
science of tomorrow. Certainly the science that will come!

Does the _Albatross_ still cruise in the atmosphere in the realm that
none can take from her? There is no reason to doubt it.

Will Robur, the Conqueror, appear one day as he said? Yes! He will
come to declare the secret of his invention, which will greatly
change the social and political conditions of the world.

As for the future of aerial locomotion, it belongs to the aeronef and
not the aerostat.

It is to the _Albatross_ that the conquest of the air will assuredly
fall.
