Five Thousand Miles Underground
The lower hull or main part of the craft was one hundred and fifty feet long, and forty feet through at the largest part, in the centre.
It was divided into four sections. The forward one contained the sleeping quarters of Professor Henderson and his crew. There was a small stateroom for each one. Above was a conning or observation tower, reached by a small flight of steps. From this tower the ship could be steered, stopped and started, as could also be done from the engine room, which was in the after part of the hull.
As in the Porpoise and Monarch, electricity formed the motive power and was also used for many other purposes on board. Engines operated by gas produced the current which heated, lighted and moved the ship, as well as played a part in producing the wonderful gas.
