PART II.
CHAPTER I THE INDIAN OCEAN
E now come to the second part of our journey under the sea. The first ended with the moving scene in the coral cemetery, which left such a deep impression on my mind. Thus, in the midst of this great sea, Captain Nemo's life was passing even to his grave, which he had prepared in one of its deepest abysses. There, not one of the ocean's monsters could trouble the last sleep of the crew of the Nautilus, of those friends riveted to each other in death as in life. "Nor any man either," had added the captain. Still the same fierce, implacable defiance toward human society!
I could no longer content myself with the hypothesis which satisfied Conseil. That worthy fellow persisted in seeing in the commander of the Nautilus one of those unknown savants who return mankind contempt for indifference.
For him, he was a misunderstood genius, who, tired of earth's deceptions, had taken refuge in this inaccessible medium, where he might follow his instincts freely. To my mind, this hypothesis explained but one side of Captain Nemo's character.
Indeed, the mystery of that last night, during which we had been locked in prison, the sleep, and the precaution so violently taken by the captain of snatching from my eyes the glass I had raised to sweep the horizon, the mortal wound of the man, due to an unaccountable shock of the Nautilus, all put me on a new track.
No; Captain Nemo was not satisfied with shunning man. His formidable apparatus not only suited his instinct of freedom, but, perhaps, also the design of some terrible retaliation.
At this moment nothing is clear to me; I catch but a glimpse of light amid all the darkness, and I must confine myself to writing as events shall dictate.
That day, the 24th of January, 1868, at noon, the second ​officer came to take the altitude of the sun. I mounted the platform, lit a cigar, and watched the operation. It seemed to me that the man did not understand French; for several times I made remarks in a loud voice, which must have drawn from him some involuntary sign of attention, if he had understood them; but he remained undisturbed and dumb.
As he was taking observations with the sextant, one of the sailors of the Nautilus (the strong man who had accompanied us on our first submarine excursion to the island of Crespo) came to clean the glasses of the lantern. I examined the fittings of the apparatus, the strength of which was increased a hundredfold by lenticular rings, placed similar to those in a lighthouse, and which projected their brilliance in a horizontal plane. The electric lamp was combined in such a way as to give its most powerful light. Indeed it was produced in vacuo, which insured both its steadiness and its intensity. This vacuum economized the graphite points, between which the luminous arc was developed—an important point of economy for Captain Nemo, who could not easily have replaced them; and under these conditions their waste was imperceptible. When the Nautilus was ready to continue its submarine journey, I went down to the saloon. The panels were closed and the course marked direct west.
We were furrowing the waters of the Indian Ocean, a vast liquid plain with a surface of 1,200,000,000 of acres, whose waters are so clear and transparent that any one leaning over them would turn giddy. The Nautilus usually floated between fifty and a hundred fathoms deep. We went on so for some days. To any one but myself, who had a great love for the sea, the hours would have seemed long and monotonous; but the daily walks on the platform, when I steeped myself in the reviving air of the ocean, the sight of the rich waters through the windows of the saloon, the books in the library, the compiling of my memoirs, took up all my time, and left me not a moment of ennui or weariness.
From the 21st to the 23d of January, the Nautilus went at the rate of two hundred and fifty leagues in twenty-four hours, being five hundred and forty miles, or twenty-two miles an hour. If we recognized many different varieties ​of fish, it was because, attracted by the electric light, they tried to follow us; the greater part, however, were soon distanced by our speed, though some kept their place in the waters of the Nautilus for a time. The morning of the 24th, in 12° 5′ south latitude, and 94° 33′ longitude, we observed Keeling Island, a madrepore formation, planted with magnificent cocoas, which had been visited by Mr. Darwin and Captain Fitzroy. The Nautilus skirted the shores of this desert island for a little distance. Its nets brought up numerous specimens of polypi, and curious shells of mollusks. Some precious productions of the species of delphinulæ enriched the treasures of Captain Nemo, to which I added an astræa punctifera, a kind of parasite polypus often found fixed to a shell. Soon Keeling Island disappeared from the horizon, and our course was directed to the northwest in the direction of the Indian Peninsula.
From Keeling Island our course was slower and more variable, often taking us into great depths. Several times they made use of the inclined planes, which certain internal levers placed obliquely to the water-line. In that way we went about two miles, but without ever obtaining the greatest depths of the Indian Sea, which soundings of seven thousand fathoms have never reached. As to the temperature of the lower strata, the thermometer invariably indicated 4° above zero. I only observed that, in the upper regions, the water was always colder in the high levels than at the surface of the sea.
On the 25th of January, the ocean was entirely deserted; the Nautilus passed the day on the surface, beating the waves with its powerful screw, and making them rebound to a great height. Who under such circumstances would not have taken it for a gigantic cetacean? Three parts of this day I spent on the platform. I watched the sea. Nothing on the horizon, till about four o'clock a steamer running west on our counter. Her masts were visible for an instant, but she could not see the Nautilus, being too low in the water. I fancied this steamboat belonged to the P. O. Company, which runs from Ceylon to Sydney, touching at King George's Point and Melbourne.
At five o'clock in the evening, before that fleeting twilight which binds night to day in tropical zones, Conseil and I were astonished by a curious spectacle.
​It was a shoal of argonauts traveling along on the surface of the ocean. We could count several hundreds. They belonged to the tubercle kind which are peculiar to the Indian seas.
These graceful mollusks moved backward by means of their locomotive tube, through which they propelled the water already drawn in. Of their eight tentacles, six were elongated, and stretched out floating on the water, while the other two, rolled up flat, were spread to the wind like a light sail. I saw their spiral-shaped and fluted shells, which Cuvier justly compares to an elegant skiff. A boat indeed! It bears the creature which secretes it without its adhering to it.
For nearly an hour the Nautilus floated in the midst of this shoal of mollusks. Then I know not what sudden fright they took; but as if at a signal every sail was furled, the arms folded, the body drawn in, the shells turned over, changing their center of gravity, and the whole fleet disappeared under the waves. Never did the ships of a squadron maneuver with more unity. At that moment night fell suddenly, and their reeds, scarcely raised by the breeze, lay peaceably under the sides of the Nautilus.
The next day, 26th of January, we cut the equator at the eighty-second meridian, and entered the northern hemisphere. During the day, a formidable troop of sharks accompanied us, terrible creatures, which multiply in these seas, and make them very dangerous. They were "cestracio philippi" sharks, with brown backs and whitish bellies, armed with eleven rows of teeth—eyed sharks—their throat being marked with a large black spot surrounded with white like an eye. There were also some Isabella sharks, with rounded snouts marked with dark spots. These powerful creatures often hurled themselves at the windows of the saloon with such violence as to make us feel very insecure. At such times Ned Land was no longer master of himself. He wanted to go to the surface and harpoon the monsters, particularly certain smooth-hound sharks, whose mouth is studded with teeth like a mosaic; and large tiger-sharks nearly six yards long, the last-named of which seemed to excite him more particualrly. But the Nautilus accelerating her speed, easily left the most rapid of them behind.
​The 27th of January, at the entrance of the vast Bay of Bengal, we met repeatedly a forbidding spectacle—dead bodies floating on the surface of the water. They were the dead of the Indian villages, carried by the Ganges to the level of the sea, and which the vultures, the only undertakers of the country, had not been able to devour. But the sharks did not fail to help them at their funereal work.
About seven o'clock in the evening, the Nautilus, half immersed, was sailing in a sea of milk. At first sight the ocean seemed lactified. Was it the effect of the lunar rays? No; for the moon, scarcely two days old, was still lying hidden under the horizon in the rays of the sun. The whole sky, though lit by the sidereal rays, seemed black by contrast with the whiteness of the waters.
Conseil could not believe his eyes, and questioned me as to the cause of this strange phenomenon. Happily I was able to answer him.
"It is called a milk sea," I explained; "a large extent of white wavelets often to be seen on the coasts of Amboyna, and in these parts of the sea."
"But, sir," said Conseil, "can you tell me what causes such an effect? for I suppose the water is not really turned into milk."
"No, my boy; and the whiteness which surprises you is caused only by the presence of myriads of infusoria, a sort of luminous little worm, gelatinous and without color, of the thickness of a hair, and whose length is not more than the seven-one-thousandths of an inch. These insects adhere to one another sometimes for several leagues."
"Several leagues!" exclaimed Conseil.
"Yes, my boy; and you need not try to compute the number of these infusoria. You will not be able; for, if I am not mistaken, ships have floated on these milk seas for more than forty miles."
Toward midnight the sea suddenly resumed its usual color; but behind us, even to the limits of the horizon, the sky reflected the whitened waves, and for a long time seemed impregnated with the vague glimmerings of an aurora borealis.
