“Exactly so. These mines extend under the waves like the mines of Newcastle. Here, in their diving-dresses, pickaxe and shovel in hand, my men extract the coal, which I do not even ask from the mines of the earth. When I burn this combustible for the manufacture of sodium, the smoke, escaping from the crater of the mountain, gives it the appearance of a still active volcano.”
“And we shall see your companions at work?”
“No; not this time at least; for I am in a hurry to continue our submarine tour of the earth. So I shall content myself with drawing from the reserve of sodium I already possess. The time for loading is one day only, and we continue our voyage. So if you wish to go over the cavern, and make the round of the lagoon, you must take advantage of to-day, M. Aronnax.”
I thanked the captain, and went to look for my companions, who had not yet left their cabin. I invited them to follow me without saying where we were. They mounted the platform. Conseil, who was astonished at nothing, seemed to look upon it as quite natural that he should wake under a mountain, after having fallen asleep under the waves. But Ned Land thought of nothing but finding whether the cavern had any exit. After breakfast, about ten o’clock, we went down on to the mountain.
“Here we are, once more on land,” said Conseil.
“I do not call this land,” said the Canadian. “And besides, we are not on it, but beneath it.”
Between the walls of the mountain and the waters of the lake lay a sandy shore, which, at its greatest breadth, measured five hundred feet. On this soil one might easily make the tour of the lake. But the base of the high partitions was stony ground, with volcanic blocks and enormous pumice-stones lying in picturesque heaps. All these detached masses, covered with enamel, polished by the action of the subterraneous fires, shone resplendent by the light of our electric lantern. The mica-dust from the shore, rising under our feet, flew like a cloud of sparks. The bottom now rose sensibly, and we soon arrived at long circuitous slopes, or inclined planes, which took us higher by degrees; but we were obliged to walk carefully among these conglomerates, bound by no cement, the feet slipping on the glassy trachyte, composed of crystal, felspar, and quartz.
The volcanic nature of this enormous excavation was confirmed on all sides, and I pointed it out to my companions.
“Picture to yourselves,” said I, “what this crater must have been when filled with boiling lava, and when the level of the incandescent liquid rose to the orifice of the mountain, as though melted on the top of a hot plate.”
“I can picture it perfectly,” said Conseil. “But, sir, will you tell me why the Great Architect has suspended operations, and how it is that the furnace is replaced by the quiet waters of the lake?”
“Most probably, Conseil, because some convulsion beneath the ocean produced that very opening which has served as a passage for the Nautilus. Then the waters of the Atlantic rushed into the interior of the mountain. There must have been a terrible struggle between the two elements, a struggle which ended in the victory of Neptune. But many ages have run out since then, and the submerged volcano is now a peaceable grotto.”
“Very well,” replied Ned Land; “I accept the explanation, sir; but, in our own interests, I regret that the opening of which you speak was not made above the level of the sea.”
“But, friend Ned,” said Conseil, “if the passage had not been under the sea, the Nautilus could not have gone through it.”
We continued ascending. The steps became more and more perpendicular and narrow. Deep excavations, which we were obliged to cross, cut them here and there; sloping masses had to be turned. We slid upon our knees and crawled along. But Conseil’s dexterity and the Canadian’s strength surmounted all obstacles. At a height of about thirty-one feet, the nature of the ground changed without becoming more practicable. To the conglomerate and trachyte succeeded black basalt, the first dispread in layers full of bubbles, the latter forming regular prisms, placed like a colonnade supporting the spring of the immense vault, an admirable specimen of natural architecture. Between the blocks of basalt wound long streams of lava, long since grown cold, encrusted with bituminous rays; and in some places there were spread large carpets of sulphur. A more powerful light shone through the upper crater, shedding a vague glimmer over these volcanic depressions forever buried in the bosom of this extinguished mountain. But our upward march was soon stopped at a height of about two hundred and fifty feet by impassable obstacles. There was a complete vaulted arch overhanging us, and our ascent was changed to a circular walk. At the last change vegetable life began to struggle with the mineral. Some shrubs, and even some trees, grew from the fractures of the walls. I recognized some euphorbias, with the caustic sugar coming from them; heliotropes, quite incapable of justifying their name, sadly drooped their clusters of flowers, both their color and perfume half gone. Here and there some chrysanthemums grew timidly at the foot of an aloe with long sickly looking leaves. But between the streams of lava, I saw some little violets still slightly perfumed, and I admit that I smelt them with delight. Perfume is the soul of the flower, and sea-flowers, those splendid hydrophytes, have no soul.
We had arrived at the foot of some sturdy dragon trees, which had pushed aside the rocks with their strong roots, when Ned Land exclaimed:
“Ah! sir, a hive! A hive!”
“A hive!” I replied with a gesture of incredulity.
“Yes, a hive,” repeated the Canadian, “and bees humming round it.”
I approached, and was bound to believe my own eyes. There, at a hole bored in one of the dragon trees, were some thousands of these ingenious insects, so common in all the Canaries, and whose produce is so much esteemed. Naturally enough, the Canadian wished to gather the honey, and I could not well oppose his wish. A quantity of dry leaves, mixed with sulphur, he lit with a spark from his flint, and he began to smoke out the bees. The humming ceased by degrees, and the hive eventually yielded several pounds of the sweetest honey, with which Ned Land filled his haversack.
“When I have mixed this honey with the paste of the artocarpus,” said he, “I shall be able to offer you a succulent cake.”
“Upon my word,” said Conseil, “it will be gingerbread.”
“Never mind the gingerbread,” said I; “let us continue our interesting walk.”
At every turn of the path we were following, the lake appeared in all its length and breadth. The lantern lit up the whole of its peaceable surface which knew neither ripple nor wave. The Nautilus remained perfectly immovable. On the platform, and on the mountain, the ship’s crew were working like black shadows clearly carved against the luminous atmosphere. We were now going round the highest crest of the first layers of rock which upheld the roof. I then saw that bees were not the only representatives of the animal kingdom in the interior of this volcano. Birds of prey hovered here and there in the shadows, or fled from their nests on the top of the rocks. There were sparrow-hawks with white breasts, and kestrels, and down the slopes scampered, with their long legs, several fine fat bustards. I leave anyone to imagine the covetousness of the Canadian at the sight of this savory game, and whether he did not regret having no gun. But he did his best to replace the lead by stones, and after several fruitless attempts, he succeeded in wounding a magnificent bird. To say that he risked his life twenty times before reaching it, is but the truth; but he managed so well that the creature joined the honey cakes in his bag. We were now obliged to descend toward the shore, the crest becoming impracticable. Above us the crater seemed to gape like the mouth of a well. From this place the sky could be clearly seen, and clouds, dissipated by the west wind, leaving behind them, even on the summit of the mountain, their misty remnants—certain proof that they were only moderately high, for the volcano did not rise more than eight hundred feet above the level of the ocean. Half an hour after the Canadian’s last exploit we had regained the inner shore. Here the flora was represented by large carpets of marine crystal, a little umbelliferous plant very good to pickle, which a
lso bears the name of pierce-stone and sea-fennel. Conseil gathered some bundles of it. As to the fauna, it might be counted by thousands of crustacea of all sorts, lobsters, crabs, palæmons, spider crabs, chameleon shrimps, and a large number of shells, rockfish, and limpets. Three-quarters of an hour later, we had finished our circuitous walk, and were on board. The crew had just finished loading the sodium, and the Nautilus could have left that instant. But Captain Nemo gave no order. Did he wish to wait until night, and leave the submarine passage secretly? Perhaps so. Whatever it might be, the next day, the Nautilus, having left its port, steered clear of all land at a few yards beneath the waves of the Atlantic.
Chapter XI
The Sargasso Seabt
THAT DAY THE NAUTILUS crossed a singular part of the Atlantic Ocean. No one can be ignorant of the existence of a current of warm water, known by the name of the Gulf Stream. After leaving the Gulf of Mexico, about the twenty-fifth degree of north latitude, this current divides into two arms, the principal one going toward the coast of Ireland and Norway, while the second bends to the south about the height of the Azores; then, touching the African shore, and describing a lengthened oval, returns to the Antilles. This second arm—it is rather a collar than an arm—surrounds with its circles of warm water that portion of the cold, quiet, immovable ocean called the Sargasso Sea, a perfect lake in the open Atlantic: it takes no less than three years for the great current to pass round it. Such was the region the Nautilus was now visiting, a perfect meadow, a close carpet of seaweed, fucus, and tropical berries, so thick and so compact that the stem of a vessel could hardly tear its way through it. And Captain Nemo, not wishing to entangle his screw in this herbaceous mass, kept some yards beneath the surface of the waves. The name Sargasso comes from the Spanish word sargazzo which signifies kelp. This kelp or varech, or berry-plant, is the principal formation of this immense bank. And this is the reason, according to the learned Maury, the author of The Physical Geography of the Globe, why these hydrophytes unite in the peaceful basin of the Atlantic. The only explanation which can be given, he says, seems to me to result from the experience known to all the world. Place in a vase some fragments of cork or other floating body, and give to the water in the vase a circular movement the scattered fragments will unite in a group in the center of the liquid surface, that is to say, in the part least agitated. In the phenomenon we are considering, the Atlantic is the vase, the Gulf Stream the circular current, and the Sargasso Sea the central point at which the floating bodies unite.
I share Maury’s opinion, and I was able to study the phenomenon in the very midst, where vessels rarely penetrate. Above us floated products of all kinds, heaped up among these brownish plants; trunks of trees torn from the Andes or the Rocky Mountains, and floated by the Amazon or the Mississippi; numerous wrecks, remains of keels, or ships’ bottoms, side planks stove in, and so weighted with shells and barnacles that they could not again rise to the surface. And time will one day justify Maury’s other opinion, that these substances thus accumulated for ages will become petrified by the action of the water, and will then form inexhaustible coal mines—a precious reserve prepared by far-seeing nature for the moment when men shall have exhausted the mines of continents.
In the midst of this inextricable mass of plants and seaweed, I noticed some charming pink halcyons and actiniae, with their long tentacles trailing after them; medusæ, green, red, and blue, and the great rhyostoms of Cuvier, the large umbrella of which was bordered and festooned with violet.
All the day of the 22d of February we passed in the Sargasso Sea, where such fish as are partial to marine plants and fuci find abundant nourishment. The next, the ocean had returned to its accustomed aspect. From this time for nineteen days, from the 23d of February to the 12th of March, the Nautilus kept in the middle of the Atlantic, carrying us at a constant speed of a hundred leagues in twenty-four hours. Captain Nemo evidently intended accomplishing his submarine programme, and I imagined that he intended, after doubling Cape Horn, to return to the Australian seas of the Pacific. Ned Land had cause for fear. In these large seas, void of islands, we could not attempt to leave the boat. Nor had we any means of opposing Captain Nemo’s will. Our only course was to submit; but what we could neither gain by force nor cunning, I liked to think might be obtained by persuasion. This voyage ended, would he not consent to restore our liberty, under an oath never to reveal his existence—an oath of honor which we should have religiously kept? But we must consider that delicate question with the captain. But was I free to claim this liberty? Had he not himself said from the beginning, in the firmest manner, that the secret of his life exacted from him our lasting imprisonment on board the Nautilus? And would not my four months’ silence appear to him a tacit acceptance of our situation? And would not a return to the subject result in raising suspicions which might be hurtful to our projects if at some future time a favorable opportunity offered to return to them?
During the nineteen days mentioned above, no incident of any note happened to signalize our voyage. I saw little of the captain; he was at work. In the library I often found his books left open, especially those on natural history. My work on submarine depths, conned over by him, was covered with marginal notes, often contradicting my theories and systems; but the captain contented himself with thus purging my work; it was very rare for him to discuss it with me. Sometimes I heard the melancholy tones of his organ; but only at night, in the midst of the deepest obscurity, when the Nautilus slept upon the deserted ocean. During this part of our voyage we sailed whole days on the surface of the waves. The sea seemed abandoned. A few sailing-vessels, on the road to India, were making for the Cape of Good Hope. One day we were followed by the boats of a whaler, who, no doubt, took us for some enormous whale of great price; but Captain Nemo did not wish the worthy fellows to lose their time and trouble, so ended the chase by plunging under the water. Our navigation continued until the 13th of March; that day the Nautilus was employed in taking soundings, which greatly interested me. We had then made about 13,000 leagues since our departure from the high seas of the Pacific. The bearings gave us 45° 37’ south latitude, and 37° 53’ west longitude. It was the same water in which Captain Denham, of the Herald, sounded 7,000 fathoms without finding the bottom. There, too, Lieutenant Parker, of the American frigate Congress, could not touch the bottom with 15,140 yards. Captain Nemo intended seeking the bottom of the ocean by a diagonal sufficiently lengthened by means of lateral planes, placed at an angle of forty-five degrees with the water-line of the Nautilus. Then the screw set to work at its maximum speed, its four blades beating the waves with indescribable force. Under this powerful pressure the hull of the Nautilus quivered like a sonorous chord, and sank regularly under the water.
At 7,000 fathoms I saw some blackish tops rising from the midst of the waters; but these summits might belong to high mountains like the Himalayas or Mont Blanc, even higher; and the depth of the abyss remained incalculable. The Nautilus descended still lower, in spite of the great pressure. I felt the steel plates tremble at the fastenings of the bolts; its bars bent, its partitions groaned; the windows of the saloon seemed to curve under the pressure of the waters. And this firm structure would doubtless have yielded, if, as its captain had said, it had not been capable of resistance like a solid block. In skirting the declivity of these rocks, lost under the water, I still saw some shells, some serpulæ and spinorbes, still living, and some specimens of asteriads. But soon this last representative of animal life disappeared; and at the depth of more than three leagues, the Nautilus had passed the limits of submarine existence, even as a balloon does when it rises above the respirable atmosphere. We had attained a depth of 16,000 yards (four leagues), and the sides of the Nautilus then bore a pressure of 1,600 atmospheres, that is to say, 3,200 pounds to each square two-fifths of an inch of its surface.
“What a situation to be in!” I exclaimed. “To overrun these deep regions where man has never trod! Look, captain, look at these magnific
ent rocks, these uninhabited grottoes, these lowest receptacles of the globe, where life is no longer possible! What unknown sights are here! Why should we be unable to preserve a remembrance of them?”
“Would you like to carry away more than the remembrance?” said Captain Nemo.
“What do you mean by those words?”
“I mean to say that nothing is easier than to take a photographic view of this submarine region.”
I had not time to express my surprise at this new proposition, when, at Captain Nemo’s call, an objective was brought into the saloon. Through the widely opened panel, the liquid mass was bright with electricity, which was distributed with such uniformity that not a shadow, not a gradation, was to be seen in our manufactured light. The Nautilus remained motionless, the force of its screw subdued by the inclination of its planes: the instrument was propped on the bottom of the oceanic site, and in a few seconds we had obtained a perfect negative. I here give the positive, from which may be seen those primitive rocks, which have never looked upon the light of heaven; that lowest granite which forms the foundation of the globe; those deep grottoes, woven in the stony mass whose outlines were of such sharpness, and the border lines of which are marked in black, as if done by the brush of some Flemish artist. Beyond that again a horizon of mountains, an admirable undulating line, forming the prospective of the landscape. I cannot describe the effect of these smooth, black, polished rocks, without moss, without a spot, and of strange forms, standing solidly on the sandy carpet, which sparkled under the jets of our electric light.
But the operation being over, Captain Nemo said: “Let us go up; we must not abuse our position, nor expose the Nautilus too long to such great pressure.”
“Go up again!” I exclaimed.
“Hold well on.”
I had not time to understand why the captain cautioned me thus, when I was thrown forward on to the carpet. At a signal from the captain, its screw was shipped, and its blades raised vertically; the Nautilus shot into the air like a balloon, rising with stunning rapidity, and cutting the mass of waters with a sonorous agitation. Nothing was visible; and in four minutes it had shot through the four leagues which separated it from the ocean, and, after emerging like a flying-fish, fell, making the waves rebound to an enormous height.
