TWENTY THOUSAND LEAGUES
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.
