The Frenchman smiled.

"M. Versal," he replied, "I have taken the liberty to look over the stock of materials which you have so wisely prepared for possible repairs to the Ark and for use after the Ark lands, and I know that among them I can find all that I shall need. You yourself know how completely you are provided with engineering tools and machines of all kinds. You have even an electric foundry aboard. With the aid of your mechanical genius, and the skill of your a.s.sistants, together with that of my own men, who are accustomed to work of this kind, I have not the faintest doubt that I can design and construct a diving-bell, large enough to contain a half-dozen persons, and perfectly capable of penetrating to any depth. Of course I cannot make it of levium, but you have a sufficient supply of herculeum steel, the strength of which is so immense that the walls of the bell can be made to remit the pressure even at a depth of six miles. From my previous experiments I am confident that there will be no difficulty in sinking and afterward raising this apparatus. It is only necessary that the mean specific gravity of the bell shall be greater than that of the water at a given depth, and you know that as far back as the end of the nineteenth century your own countrymen sent down sounding apparatus more than six miles in the Pacific Ocean, near the island of Guam."

"But the air inside the bell--" Cos...o...b..gan.

"Excuse me," interrupted De Beauxchamps, "but that air need be under no greater pressure than at the surface. I shall know how to provide for that. Remember the _Jules Verne_. Simply give me _carte blanche_ in this matter, let me have the materials to work with, afford me the advantage of your advice and a.s.sistance whenever I shall need them, and I promise you that by the time we have arrived over the site of New York we shall be prepared for the descent."

Cosmo was deeply impressed by the Frenchman's enthusiastic self-confidence. He had a great admiration for the constructor of the _Jules Verne_, and, besides, the proposed adventure was exactly after his own heart. After meditating a while, he said heartily:

"Well, M. De Beauxchamps, I give my consent. Everything you wish shall be at your disposal, and you can begin as soon as you choose. Only, let the thing be kept a secret between us and the workmen who are employed.

If it should turn out a failure it would not do that the people in the Ark should be aware of it. I can give you a working room on one of the lower decks, where there will be no interference with your proceedings, and no knowledge of what you are about can leak out."

"That is exactly what I should wish," returned De Beauxchamps, smiling with delight, "and I renew my promise that you shall not be disappointed."

So, without a suspicion of what was going on entering the minds of any person in the great company outside the small company of men who were actually employed in the work, the construction of De Beauxchamps's great diving-bell was begun, and pushed with all possible speed, consistent with the proper execution of the work. In the meantime the Ark continued its course toward the west.

They ran slowly, for there was no hurry, and the Ark had now become to its inhabitants as a house and a home--their only foothold on the whole round earth, and that but a little floating island of buoyant metal.

They crossed the Pamirs and the Hindu-Kush, the place where the Caspian Sea had been swallowed up in the universal ocean, and ran over Ararat, which three months before had put them into such fearful danger, but whose loftiest summit now lay twelve thousand feet beneath their keel.

At length, after many excursions toward the north and toward the south, in the halcyon weather that had seldom failed since the withdrawal of the nebula, they arrived at the place (or above it) which had stood during centuries for a noon-mark on the globe.

It was midday when Captain Arms, having made his observations, said to Cosmo and the others on the bridge:

"Noon at Greenwich, and noon on the Ark. Lat.i.tude, fifty-one degrees thirty minutes. That brings you as nearly plumb over the place as you'd be likely to hit it. Right down there lies the old observatory that set the chronometers of the world, and kept the clocks and watches up to their work."

King Richard turned aside upon hearing the captain's words. They brought a too vivid picture of the great capital, six miles under their feet, and a too poignant recollection of the disastrous escape of the royal family from overwhelmed London seven months before.

As reckoned by the almanac, it was the 15th of September, more than sixteen months since Cosmo had sent out his first warning to the public, when the Ark crossed the meridian of seventy-four degrees west, in about forty-one degrees north lat.i.tude, and the adventurers knew that New York was once more beneath them.

There was great emotion among both pa.s.sengers and crew, for the majority of them had either dwelt in New York or been in some way a.s.sociated with its enterprises and its people, and, vain as must be the hope of seeing any relic of the buried metropolis, every eye was on the alert.

They looked off across the boundless sea in every direction, interrogating every suspicious object on the far horizon, and even peering curiously into the blue abyss, as if something might suddenly appear there which would speak to them like a voice from the past.

But they saw only shafts of sunlight running into bottomless depths, and occasionally some oceanic creature floating lazily far below. The color of the sea was wonderful. It had attracted their attention after the submergence of Mount Everest, but at that time it had not yet a.s.sumed its full splendor.

At first, no doubt, there was considerable dissolved matter in the water, but gradually this settled, and the sea became bluer and bluer--not the deep indigo of the old ocean, but a much lighter and more brilliant hue--and here, over the site of New York, the waters were of a bright, luminous sapphire, that dazzled the eye.

Cosmo declared that the change of the sea-color was undoubtedly due to some quality in the nebula from whose condensation the water had been produced, but neither his own a.n.a.lyses, nor those of the chemists aboard the Ark, were able to detect the subtle element to whose presence the peculiar tint was due.

But whatever it may have been, it imparted to the ocean an ethereal, imponderous look, which was sometimes startling. There were moments when they almost expected to see it expand back into the nebulous form and fly away.

CHAPTER XXV

NEW YORK IN HER OCEAN TOMB

During the long voyage from the sunken Himalayas to still deeper sunken New York, De Beauxchamps, with his fellow-countrymen and the skilled mechanics a.s.signed by Cosmo Versal to aid them, had finished the construction of the huge diving-bell. No one not in the secret had the slightest idea of what had been done, owing to the remote situation of the deck on which the construction was carried out.

Now, while a thousand pairs of eyes were interrogating the smooth surface of the sea, and striving to penetrate its cerulean depths, a great surprise was sprung upon the pa.s.sengers. The rear gangway of the lowest deck was cleared, a heavy crane-like beam was set projecting over the water, and men began to rig a flexible cable, which had been specially prepared for the purpose of lowering the bell into the depths, and of raising it again when the adventurers should wish to return to the surface. Everybody's attention was immediately attracted to these strange preparations, and the utmost curiosity was aroused. A chorus of wondering exclamations broke out when a metallic globe, twenty feet in diameter, and polished until it shone like a giant thermometer bulb, was rolled out and carefully attached to the cable by means of a strong ring set in one side of the bell. The excitement of the pa.s.sengers would soon have become uncontrollable if Cosmo had not at this point summoned the entire ship's company into the great saloon. As soon as all were a.s.sembled he mounted his dais and began to speak.

"My fellow-citizens of the old world, which has perished, and of the new, which is to take its place," he said, "we owe to the genius of M.

De Beauxchamps an apparatus which is about to enable us to inspect, by an actual visit, the remains of the vast metropolis, which we saw in all its majesty and beauty but so few months ago, and which now lies forever silent at the bottom of this universal ocean.

"If it were practicable I should wish to afford to every one of you a farewell glimpse of that mighty city, to which the hearts of so many here are bound, but you can readily understand that that would be impossible. Only six persons can go in this exploring bell, and they have been chosen; but a faithful account will be brought back to you of all that they see and learn. The adventuring company will consist of M.

De Beauxchamps, M. Pujol, his first a.s.sistant, Mr. Amos Blank, King Richard, Professor Abel Able, and myself. Captain Arms has ascertained the location of the center of Manhattan Island, over which we are now floating. The quietness of the sea, the absence of any apparent current, and the serenity of the heavens are favoring circ.u.mstances, which may be relied upon to enable Captain Arms to keep the Ark constantly poised almost precisely over our point of descent. It is not possible to predict the exact duration of our absence in the depths, but it will not, in any case, exceed about twenty hours.

"Once arrived at the bottom, nearly six miles down, we shall attach the cable to some secure anchorage, by means of a radio-control, operated from within the bell, and then, with the bell free, we shall make explorations, as extensive as possible. The radio-control of which I have spoken governs also the attachment of the cable to the bell. This appliance has been prepared and tested with such care that we have no doubt of its entire efficiency. I mention these things in order to remove from your minds any fear as to the success of our enterprise.

"The bell being once detached, we shall be able to move it from point to point by means of a pair of small propellers, which you will perceive on the outside of the bell, and which are also controlled from within.

These will be used to increase our speed of descent. From a calculation of the density of the sea-water at the depth to which we shall descend, we estimate that the bell with its contents will press upon the bottom with a gravitational force of only five pounds, so that it will move with very slight effort, and may even, when in motion, float like a fish.

"For the purposes of observation we have provided, on four sides of the bell, a series of circular windows, with gla.s.s of immense thickness and strength, but of extraordinary transparency. Through these windows we shall be able to see in almost all directions. It was our intention to provide wireless telephone apparatus with which we might have kept you informed of all our doings and discoveries, but unfortunately we have found it impracticable to utilize our control for that purpose. We shall, however, be able to send and receive signals as long as we are connected with the cable.

"I should add that the construction of the bell, although suggested by M. De Beauxchamps immediately after our departure from Mount Everest, has been carried on in secret simply because we did not wish to subject you to the immense disappointment which you would certainly have experienced if this brilliant conception of our gifted friend, after being once made known to you, had proved to be a failure. Our preparations have all been made, and within an hour we shall begin the descent."

It is quite impossible to describe the excitement of the pa.s.sengers while they listened to this extraordinary communication. When Cosmo Versal had finished speaking he stood for some minutes looking at his audience with a triumphant smile. First a murmur of excited voices arose, and then somebody proposed three cheers, which were given and repeated until the levium dome rang with the reverberations. n.o.body knew exactly why he was cheering, but the infectious enthusiasm carried everything before it. Then the crowd began to ask questions, addressed not to Cos...o...b..t to one another. The wildest suggestions were made. One woman who had left some treasured heirlooms in a Fifth Avenue mansion demanded of her husband that he should commission Cosmo Versal to recover them.

"I'm sure they're there," she insisted. "They were locked in the safe."

"But, don't you see," protested the poor man, "he can't get outside of that bell to get 'em."

"I don't see _why_ he can't, if he should really try. I think it's too mean! They were my grandmother's jewels."

"But, my dear, how could he get out?"

"Well, _how does he get in?_ What's his radio-control good for; won't that help him? What is he going down there for if he can't do a little thing like that, to oblige?"

She pouted at her husband because he persistently refused to present her request to Cosmo, and declared that she would do it herself, then, for she must have those jewels, now that they were so near.

But Cosmo was saved from this, and other equally unreasonable demands, by a warning from De Beauxchamps that all was ready, and that no time should be lost. Then everybody hastened out on the decks to watch the departure of the adventurers. Many thoughtfully shook their heads, predicting that they would never be seen again. As soon as this feeling began to prevail the enthusiasm quickly evaporated, and efforts were made to dissuade Cosmo and De Beauxchamps from making the attempt. But they were deaf to all remonstrance, and pushing out of the chattering crowd, Cosmo ordered the gangway about the bell to be cleared of all bystanders. The opposition heated his blood a little, and he began to bear himself with an air which recalled his aspect when he quelled and punished the mutiny. This was enough to silence instantly every objector to his proceedings. Henceforth they kept their thoughts to themselves, although some muttered, under their breath such epithets as "fool" and "harebrain."

In about half an hour after Cosmo's speech the bell, with its hardy explorers safely inclosed within, was lowered away, and a minute later hundreds were craning their necks over the rails to watch the shining globe engulf itself swiftly in the sapphire depths. It was about nine o'clock in the morning when the descent was begun, and for a long time, so remarkable was the transparency of the water, they could see the bell sinking, and becoming smaller until it resembled a blue pearl. Sometimes a metallic flash shot from its polished sides like a gleam of violet lightning. But at length it pa.s.sed from view, swallowed up in the tremendous watery chasm.

We turn now to trace the adventures of the bell and its inmates as they entered the awful twilight of the ocean, and, sinking deeper, pa.s.sed gradually into a profundity which the sun's most powerful rays were unable to penetrate. Fortunately every one of the adventurers left a description of his experiences and sensations, so that there is no lack of authentic information to guide us.

The windows, as Cosmo had said, were so arranged that they afforded views on all sides. These views were, of course, restricted by the combined effects of the smallness of the windows and their great thickness; the inmates were somewhat like prisoners looking out of round ports cut through ma.s.sive walls, but the range of view was much widened when they placed themselves close to the gla.s.ses, because the latter were in the form of truncated cones with the base outward.

Glancing through the ports on the upper side of the bell Cosmo and his companions could perceive the huge form of the Ark, hanging like a cloud above them, but rapidly receding, while from the side ports they saw great shafts of azure sunlight, thrown into wonderful undulations by the disturbance of the water. These soon became fainter and gradually disappeared, but before the gloom of the depths settled about them they were thrilled by the spectacle of sharks and other huge fishes nosing about the outer side of the transparent cones, and sometimes opening their jaws as if trying to seize them. Most of the cone-shaped windows had flat surfaces, but a few were of spherical outline both without and within, and the radius of curvature had been so calculated that these particular windows served as huge magnifying lenses for an eye placed at a given distance. Once or twice a marine monster happened to place himself in the field of one of these magnifying windows, startling the observers almost out of their senses with his frightful appearance.

There were also four windows reserved for projecting a searchlight into the outer darkness. The inner side of the bell corresponded in curvature with the outer, so that the adventurers had no flat flooring on any side to stand upon, but this caused little inconvenience, since the walls were abundantly provided with hand and foot holds, enabling the inmates to maintain themselves in almost any position they could wish.

After a while they pa.s.sed below the range of daylight, and then they turned on the searchlight. The storage batteries which supplied energy for the searchlight and the propellers served also to operate an apparatus for clearing the air of carbonic acid, and De Beauxchamps had carefully calculated the limit of time that the air could be kept in a breathable condition. This did not exceed forty-eight hours--but as we have seen they had no intention of remaining under water longer than twenty hours at the utmost.

When the bell entered the night of the sea-depths they pa.s.sed into an apparently lifeless zone, where the searchlight, projected now on one side and now on another, revealed no more of the living forms which they had encountered above, but showed only a desert of solid transparent water. Here, amid this awful isolation, they experienced for the first time a feeling of dread and terror. An overpowering sense of loneliness and helplessness came over them, and only the stout heart of Cosmo Versal, and his rea.s.suring words, kept the others from making the signal which would have caused the bell to be hastily drawn back to the Ark.

"M. De Beauxchamps," said Cosmo, breaking the impressive silence, "to what depth have we now descended?"
