"What are you going to do, Tom?" asked Ned, as he saw his chum move the engine room telegraph signal to the stop position.

"Going to investigate," was the answer. "We might as well take the time. We may learn something of value."

"Do you think there is any treasure in her?" asked Mr. Damon.

"There might be," answered Tom. "We'll put on the diving suits and go outside."

"I hope there aren't any devil fish," remarked Ned.

"Same here," Tom agreed. "But I don't believe we'll meet with any. Will you take a chance, Ned?"

"I surely will! I'd like to find out what sort of ship that is—or rather, was, for there isn't much left of her."

He spoke truly, for indeed the torpedo had created fearful havoc. The full extent of it was not observed until Tom, Ned, Koku and two of the crew had put on diving suits and approached the hulk. She lay on her side on the sandy bottom, heeled over somewhat, and when the investigators had walked around her, as they were able to do, they saw a second, and even larger hole in the opposite side.

"Two submarines must have attacked her," said Ned, speaking through his telephone to Tom.

"Either that, or else one sent a torpedo into her, dived, came up on the other side and sent another."
