A Torpedo Designed by Fulton.
Go forward to the conical compartment at the very bow. There you will find the torpedo chamber for the submarine, like the cigar to which it is so often compared, carries its fire at its front tip. The most common type of boat will have two or four torpedo tubes in this chamber. The more modern ones will have a second torpedo chamber astern with the same number of tubes and carry other torpedoes on deck which by an ingenious device can be launched from their outside cradles by mechanism within the boat. In the torpedo chamber are twice as many spare torpedoes as there are tubes, made fast along the sides. Here too the anchor winch stands with the cable attached to the anchor outside the boat and an automatic knife which cuts the cable should the anchor be fouled.

The Method of Attack by Nautilus.
Immediately aft of the torpedo chamber, cut off by a water-tight partition, is the battery compartment. It gets its name because of the fact, that beneath the deck which is full of traps readily raised are the electric storage batteries of anywhere from 60 to 260 cells according to the size of the boat. This room is commonly used as the loafing place for the crew, being regarded as very spacious and empty. In it are nothing but the electric stove, the kitchen sink, the various lockers for food and all the housekeeping apparatus of the submarine. Mighty trim and compact they all are. The builder of twentieth century flats with his kitchenettes and his in-door beds might learn a good deal from a study of the smaller type of submarine. Next aft come the officers' staterooms, rather smaller than prison cells, each holding a bunk, a bureau, and a desk. Each holds also a good deal of moisture, for the greatest discomfort in submarine life comes from the fact that everything is dripping with the water resulting from the constant condensation of the air within.
