rowful thought, "M. Aronnax," he asked, "do you know the depth of the ocean?"
"I only know, captain, what the principal soundings have taught us."
"Could you tell me them, so that I can suit them to my purpose? "
"These are some," I replied, "that I remember. If I am not mistaken, a depth of 8,000 yards has been found in the North Atlantic, and 2,500 yards in the Mediterranean. The most remarkable soundings have been made in the South Atlantic, near the 35th parallel, and they gave 12,000 yards, 14,000 yards, and 15,000 yards. To sum up all, it is reckoned that if the bottom of the sea were leveled, its mean depth would be about one and three-quarter leagues."
"Well, professor," replied the captain, "we shall show you better than that, I hope. As to the mean depth of this part of the Pacific, I tell you it is only 4,000 yards."
Having said this, Captain Nemo went toward the panel, and disappeared down the ladder. I followed him, and went into the large drawing-room. The screw was immediately put in motion, and the log gave twenty miles an hour.
During the days and weeks that passed, Captain Nemo was very sparing in his visits. I seldom saw him. The lieutenant pricked the ship's course regularly on the chart, so I could always tell exactly the route of the Nautilus.
Nearly every day, for some time, the panels of the drawing-room were opened, and we were never tired of penetrating the mysteries of the submarine world.
The general direction of the Nautilus was southeast, and it kept between 100 and 150 yards of depth. One day, however, I do not know why, being drawn diagonally by means of the inclined planes, it touched the bed of the sea, The thermometer indicated a temperature of 4.25 (Cent.); a temperature that at this depth seemed common to all latitudes.
At three o'clock on the morning of the 26th of November, the Nautilus crossed the tropic of Cancer at 172° longitude. On the 27th instant it sighted the Sandwich Islands, where Cook died, February 14, 1779. We had then gone 4,860 leagues from our starting-point. In the morning, when I went on the platform, I saw, two miles to windward,
