There were instruments hanging on his room, as well as in the other rooms of the submarine, showing this location and direction. Nearby, were the other instruments: the thermometer, giving the temperature inside the submarine, and a barometer, explaining the presure within the Nautilus, whether on the surface of the water, or in the dapths of the ocean.
And these instruments in here, he explained, are sure control the lights, the warmth within the submarine, and are the most important part of the Nautilus. In short, they are used to control the electricity.
Electricity? I cried in surprise.
Yes, sir. I us the chemicals found in seawater to create the electricity. I depand upon the seawater to produce the electricity, and the electricity gives heat, light, motion, and life to the Nautilus.
But not the air you breathe?
Oh! I could easily create the air from separating the chemicals that make up water, but I have no need to, as I often go to the surface of the water, and I have a great deal of air stored, if I am unable to come the surface quickly.
It is uncredible, Captain!
We have not finished, Professor Aronnax, you still not seen the back of Nautilus.
At the front of the submarine, I saw the dining room, nearly fifteen feet long, separated the library, which was also fifteen feet long. Then came the large sitting room, thirty feet long, which was separated from captain's room, about fifteen feet in length, and mine, almost eight feet long, and last, a room filled with stored air, about twenty-three feet in lengt. In total, the front of the submarine was nearly one hundred and five feet long. The doors were all tightly shut, if there was ever a leak in one of the rooms.
I followed tht captain to the center of the submarine, where we came to an iron ladder. I asked the captain what was on the second lever, and was told there was a small boat there.
What? You have a boat? I exclaimed in surprise.
Of course, it's an excellent boat, used for fishing or for pleasure, Captain Nemo replied calmly. This boat is attached to the top of the submarine, which can easily separate itself from the rest of the Nautilus, allowing the boat to go to the surface, while the submarine remains far below.
But how do you get back onboard the submarine?
I do not come back, Professor Aronnax; the submarine comes to me, as there is an electric wire connected to the boat, and I send a message through the wire when I wish for the Nautilus to the surface.
