gasolene motors, since space was too cramped to allow the
carrying of coal for boilers. There were dynamos, motors and
powerful pumps. Some of these were for air, and some for
water. To sink the submarine below the surface large tanks
were filled with water. To insure a more sudden descent,
deflecting rudders were also used, similar to those on an
airship. There were also special air pumps, and one for the
powerful gas, which was manufactured on board.

Forward from the engine-room was a cabin, where meals
could be served, and where the travelers could remain in the
daytime. There was also a small cooking galley, or kitchen,
there. Back of the engine-room were the sleeping quarters
and the storerooms. The submarine was steered from the
forward compartment, and here were also levers, wheels and
valves that controlled all the machinery, while a number of
dials showed in which direction they were going, how deep
they were, and at what speed they were moving, as well as
what the ocean pressure was.

On top, forward, was a small conning, or observation
tower, with auxiliary and steering and controlling apparatus
there. This was to be used when the ship was moving along
on the surface of the ocean, or merely with the deck awash.
There was a small flat deck surrounding the conning tower
and this was available when the craft was on the surface.

There was provision made for leaving the ship when it was
on the bed of the ocean. When it was desired to do this the
occupants put on diving suits, which were provided with
