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 had 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 irresistible.

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 calm, 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 almost

immediately. At the pole the night lengthened into one of a hundred and

seventy-nine days. 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.
