The Second Deluge Part 18

It had taken so many years and such endless labor to introduce into the Sahara sufficient water to transform its potentially rich soil into arable land that the thought of any sudden superabundance of that element was far from the minds of the industrious agriculturalists. They had heard of the inundations caused by the melting of the mountain snows elsewhere, but there were no snow-clad mountains near them to be feared.

Accordingly, when a great wave of water came rushing upon them, surmounted, where it swept over yet unredeemed areas of the desert, by immense clouds of whirling dust, that darkened the air and recalled the old days of the simoom, they were taken completely by surprise. But as the water rose higher they tried valiantly to escape. They were progressive people, and many of them had aeros. Besides, two or three lines of aero expresses crossed their country. All who could do so immediately embarked in airships, some fleeing toward Europe, and others hovering about, gazing in despair at the spreading waters beneath them.

As the invasion of the sea grew more and more serious, this flight by airship became a common spectacle over all the lower-lying parts of Europe, and in the British Isles. But, in the midst of it, the heavens opened their flood-gates, as they had done in the New World, and then the aeros, flooded with rain, and hurled about by contending blasts of wind, drooped, fluttered, and fell by hundreds into the fast mounting waves. The nebula was upon them!

In the meantime those who had provided arks of one kind or another, tried desperately to get them safely afloat. All the vessels that succeeded in leaving their wharves were packed with fugitives. Boats of every sort were pressed into use, and the few that survived were soon floating over the sites of the drowned homes of their occupants.

Before it was too late Yves de Beauxchamps and his friends launched their submarine, and plunged into the bosom of the flood.

CHAPTER XIII

STRANGE FREAKS OF THE NEBULA

We return to follow the fortunes of Cosmo Versal's Ark.

After he had so providentially picked up the crazed billionaire, Amos Blank, and his three companions, Cosmo ordered Captain Arms to bear away southeastward, bidding farewell to the drowned sh.o.r.es of America, and sailing directly over the lower part of Manhattan, and western Long Island. The navigation was not easy, and if the Ark had not been a marvelously buoyant vessel it would not long have survived. At the beginning the heavy and continuous rain kept down the waves, and the surface of the sea was comparatively smooth, but after a while a curious phenomenon began to be noticed; immense billows would suddenly appear, rushing upon the Ark now from one direction and now from another, canting it over at a dangerous angle, and washing almost to the top of the huge ellipsoid of the dome. At such times it was difficult for anybody to maintain a footing, and there was great terror among the pa.s.sengers. But Cosmo, and stout Captain Arms, remained at their post, relieving one another at frequent intervals, and never entrusting the sole charge of the vessel to any of their lieutenants.

Cosmo Versal himself was puzzled to account for the origin of the mighty billows, for it seemed impossible that they could be raised by the wind notwithstanding the fact that it blew at times with hurricane force. But at last the explanation came of itself.

Both Cosmo and the captain happened to be on the bridge together when they saw ahead something that looked like an enormous column as black as ink, standing upright on the surface of the water. A glance showed that it was in swift motion, and, more than that, was approaching in a direct line toward the Ark. In less than two minutes it was upon them.

The instant that it met the Ark a terrific roaring deafened them, and the rounded front of the dome beneath their eyes disappeared under a deluge of descending water so dense that the vision could not penetrate it. In another half minute the great vessel seemed to have been driven to the bottom of the sea. But for the peculiar construction of the shelter of the bridge its occupants would have been drowned at their posts. As it was they were soaked as if they had been plunged overboard. Impenetrable darkness surrounded them.

But the buoyant vessel shook itself, rolled from side to side, and rose with a staggering motion until it seemed to be poised on the summit of a watery mountain. Immediately the complete darkness pa.s.sed, the awful downpour ceased, although the rain still fell in torrents, and the Ark began to glide downward with sickening velocity, as if it were sliding down a liquid slope.

It was a considerable time before the two men, clinging to the supports of the bridge, were able to maintain their equilibrium sufficiently to render it possible to utter a few connected words. As soon as he could speak with reasonable comfort Cosmo exclaimed:

"Now I see what it is that causes the billows, but it is a phenomenon that I should never have antic.i.p.ated. It is all due to the nebula. Evidently there are irregularities of some kind in its const.i.tution which cause the formation of almost solid ma.s.ses of water in the atmosphere--suspended lakes, as it were--which then plunge down in a body as if a hundred thousand Niagaras were pouring together from the sky.

"These sudden accessions of water raise stupendous waves which sweep off in every direction, and that explains the billows that we have encountered."

"Well, this nebular navigation beats all my experience," said Captain Arms, wiping the water out of his eyes. "I was struck by a waterspout once in the Indian Ocean, and I thought that that capped the climax, but it was only a catspaw to this. Give me a clear offing and I don't care how much wind blows, but blow me if I want to get under any more lakes in the sky."

"We'll have to take whatever comes," returned Cosmo, "but I don't think there is much danger of running directly into many of these downpours as we did into this one. Now that we know what they are, we can, perhaps, detect them long enough in advance to steer out of their way. Anyhow, we've got a good vessel under our feet. Anything but an ark of levium would have gone under for good, and if I had not covered the vessel with the dome there would have been no chance for a soul in her."

As a matter of fact, the Ark did not encounter any more of the columns of descending water, but the frequent billows that were met showed that they were careering over the face of the swollen sea in every direction.

But there was another trouble of a different nature. The absence of sun and stars deprived them of the ordinary means of discovering their place.

They could only make a rough guess as to the direction in which they were going. The gyrostatic compa.s.ses gave them considerable a.s.sistance, and they had perfect chronometers, but these latter could be of no use without celestial observations of some kind.

At length Cosmo devised a means of obtaining observations that were of sufficient value to partially serve their purpose. He found that while the disk of the sun was completely hidden in the watery sky, yet it was possible to determine its location by means of the varying intensity of the light.

Where the sun was a concentrated glow appeared, shading gradually off on all sides. With infinite pains Cosmo, a.s.sisted by the experience of the captain, succeeded in determining the center of the maximum illumination, and, a.s.suming that to represent the true place of the sun, they got something in the nature of observations for alt.i.tude and azimuth, and Captain Arms even drew on his chart "Sumner lines" to determine the position of the Ark, although he smiled at the thought of their absurd inaccuracy. Still, it was the best they could do, and was better than nothing at all.

They kept a log going also, although, as the captain pointed out, it was not of much use to know how fast they were traveling, since they could not know the precise direction, within a whole point of the compa.s.s, or perhaps several points.

"Besides," he remarked, "what do we know of the currents? This is not the old Atlantic. If I could feel the Gulf Stream I'd know whereabouts I was, but these currents come from all directions, and a man might as well try to navigate in a tub of boiling water."

"But we can, at least, keep working eastward," said Cosmo. "My idea is first to make enough southing to get into the lat.i.tude of the Sahara Desert, and then run directly east, so as to cross Africa where there are no mountains, and where we shall be certain of having plenty of water under our keel.

"Then, having got somewhere in the neighborhood of Suez, we can steer down into the region of the Indian Ocean, and circle round south of the Himalayas. I want to keep an eye on those mountains, and stay around the place where they disappear, because that will be the first part of the earth to emerge from the flood and it is there that we shall ultimately make land."

"Well, we're averaging eight knots," said the captain, "and at that rate we ought to be in the longitude of the African coast in about twenty days.

How high will the water stand then?"

"My gages show," replied Cosmo, "that the regular fall amounts to exactly the same thing as at the beginning--two inches a minute. Of course the spouts increase the amount locally, but I don't think that they add materially to the general rise of the flood. Two inches per minute means 4,800 feet in twenty days. That'll be sufficient to make safe navigation for us all the way across northern Africa. We'll have to be careful in getting out into the Indian Ocean area, for there are mountains on both sides that might give us trouble, but the higher ones will still be in sight, and they will serve to indicate the location of the lower ranges already submerged, but not covered deeply enough to afford safe going over them."

"All right," said Captain Arms, "you're the commodore, but if we don't hang our timbers on the Mountains of the Moon, or the Alps, or old Ararat, I'm a porpoise. Why can't you keep circling round at a safe distance, in the middle of the Atlantic, until all these reefs get a good depth of water on 'em?"

"Because," Cosmo replied, "even if we keep right on now it will probably take two months, allowing for delays in getting round dangerous places, to come within sight of the Himalayas, and in two months the flood will have risen nearly 15,000 feet, thus hiding many of the landmarks. If we should hold off here a couple of months before starting eastward nothing but the one highest peak on the globe would be left in sight by the time we arrived there, and that wouldn't be anything more than a rock, so that with the uncertainty of our navigation we might not be able to find it at all. I must know the spot where Tibet sinks, and then manage to keep in its neighborhood."

That ended the argument.

"Give me a safe port, with lights and bearings, and I'll undertake to hit it anywhere in the two hemispheres, but blow me if I fancy steering for the top of the world by dead reckoning, or no reckoning at all," grumbled the captain.

At night, of course, they had not even the slight advantage that their observations of the probable place of the sun gave them when it was above the horizon. Then they had to go solely by the indications of the compa.s.s.

Still, they forged steadily ahead, and when they got into what they deemed the proper lat.i.tude, they ran for the site of the drowned Sahara.

After about a week the billowing motion caused by the descent of the "lakes in the sky" ceased entirely, to their great delight, but the lawless nebula was now preparing another surprise for them.

On the ninth night after their departure from their lodgment on the Palisades Cosmo Versal was sleeping in his bunk close by the bridge, where he could be called in an instant, dreaming perhaps of the glories of the new world that was to emerge out of the deluge, when he was abruptly awakened by the voice of Captain Arms, who appeared to be laboring under uncontrollable excitement.

"Tumble up quicker'n you ever did in your life!" he exclaimed, his big brown beard wagging almost in Cosmo's face. "The flood's over!"

Cosmo sprang out of bed and pulled on his coat in a second.

"What do you mean?" he demanded.

"Look for yourself," said the captain, pointing overhead.

Cosmo Versal glanced up and saw the sky ablaze with stars! The rain had entirely ceased. The surface of the sea was almost as smooth as gla.s.s, though rising and falling slowly, with a long, rolling motion. The Ark rode steadily, shivering, like an ocean liner, under the impulse of its engines, and the sudden silence, succeeding the ceaseless roar of the downpour, which had never been out of their ears from the start of the voyage, seemed supernatural.

"When did this happen?" he demanded.

"It began not more than five minutes ago. I was just saying to myself that we ought to be somewhere near the center of the old Atlantic as it used to be, and wondering whether we had got our course laid right to go fairly between the Canaries and the Cape de Verdes, for I didn't want to be harpooned by Gogo or the Peak of Teneriffe, when all of a sudden there came a lightening in the nor'east and the stars broke out there.

"I was so set aback that I didn't do anything for two or three minutes but stare at the stars. Then the rain stopped and a curtain seemed to roll off the sky, and in a minute more it was clear down to the horizon all around.

Then I got my wits together and ran to call you."

Cosmo glanced around and above, seeming to be as much astonished as the captain had been. He rubbed his huge bald dome and looked all round again before speaking. At last he said:

"It's the nebula again. There must be a hole in it."

"Its whole bottom's knocked out, I reckon," said the captain. "Maybe it's run out of water--sort o' squeezed itself dry."
