She was some hundreds of feet long, and made Henry think of a huge log afloat. Her rounded sides rose only a few feet above the water. Amidships was the conning tower, with its periscope. There were short masts for wireless antennæ. The very top of the hull was flattened, so that the crew could walk on it.

Perhaps it was the big guns fastened to the deck that most interested Henry. There was no way to protect them from the sea, and when the ship was running submerged, he saw that these guns would stand right up in the water.
