Really, I knew already the anterior part of this submarine boat, of which this is the exact division, starting from the ship’s head:—the dining-room, five yards long, separated from the library by a water-tight partition; the library, five yards long; the large drawing-room, ten yards long, separated from the Captain’s room by a second water-tight partition; the said room, five yards in length; mine, two and a half yards; and, lastly a reservoir of air, seven and a half yards, that extended to the bows. Total length thirty-five yards, or one hundred and five feet. The partitions had doors that were shut hermetically by means of india-rubber instruments, and they ensured the safety of the _Nautilus_ in case of a leak. I followed Captain Nemo through the waist, and arrived at the centre of the boat. There was a sort of well that opened between two partitions. An iron ladder, fastened with an iron hook to the partition, led to the upper end. I asked the Captain what the ladder was used for. “It leads to the small boat,” he said. “What! have you a boat?” I exclaimed, in surprise. “Of course; an excellent vessel, light and insubmersible, that serves either as a fishing or as a pleasure boat.” “But then, when you wish to embark, you are obliged to come to the surface of the water?” “Not at all. This boat is attached to the upper part of the hull of the _Nautilus_, and occupies a cavity made for it. It is decked, quite water-tight, and held together by solid bolts. This ladder leads to a man-hole made in the hull of the _Nautilus_, that corresponds with a similar hole made in the side of the boat. By this double opening I get into the small vessel. They shut the one belonging to the _Nautilus;_ I shut the other by means of screw pressure. I undo the bolts, and the little boat goes up to the surface of the sea with prodigious rapidity. I then open the panel of the bridge, carefully shut till then; I mast it, hoist my sail, take my oars, and I’m off.” “But how do you get back on board?” “I do not come back, M. Aronnax; the _Nautilus_ comes to me.” “By your orders?” “By my orders. An electric thread connects us. I telegraph to it, and that is enough.” “Really,” I said, astonished at these marvels, “nothing can be more simple.” After having passed by the cage of the staircase that led to the platform, I saw a cabin six feet long, in which Conseil and Ned Land, enchanted with their repast, were devouring it with avidity. Then a door opened into a kitchen nine feet long, situated between the large storerooms. There electricity, better than gas itself, did all the cooking. The streams under the furnaces gave out to the sponges of platina a heat which was regularly kept up and distributed. They also heated a distilling apparatus, which, by evaporation, furnished excellent drinkable water. Near this kitchen was a bathroom comfortably furnished, with hot and cold water taps.
