Jack went down the ladder quickly, followed by the others. They now found themselves in what might be termed the main room of the submarine. Beyond were several other compartments, including one where was located much of the machinery which ran the undersea boat.
“It’s a good deal like being downstairs on a small warship,” declared Fred. “See, there are staterooms and messrooms and everything else!”
“Well, I suppose they have to give the crew some comforts, they take such long, disagreeable trips,” remarked Jack.
The three cadets wandered around in the interior of the submarine for over a quarter of an hour. They saw where a number of repairs were being made to the side of the U-boat and also to some of the machinery, and they also saw where some stores had been taken on board, boxes and barrels of various kinds.
“I guess they are stocking up for another cruise,” remarked Gif.
“It must be quite a job to get all that stuff to this out-of-the-way place,” said Jack.
“Yes, and to do it so secretly, too,” added Fred.
“I think I see a way of making this boat stay here for a while, at least,” remarked Jack. “It will be an easy matter to put some of that delicate machinery forward out of commission.”
“Come on and do it!” cried his cousin quickly.
The three cadets were inspecting the machinery and wondering how they could damage it effectively with the least possible trouble, when there came a sudden interruption.
