"Very good," nodded Captain Magowan. "We will return to the deck. I can see that there are many questions to be asked."

On the deck, on first boarding, Jack Benson had noticed the absence of Fred Radwin. While they were below Jack had caught a glimpse of Radwin in the "Thor's" engine room.

When the naval board and the others reached the deck Captain Magowan had Captain Driggs, of the "Thor," and the members of the boat's crew lined up together.

"Have you any questions that you wish to ask, Mr. Benson?" the president of the board inquired.

"Yes, sir. At the time that the torpedo passed our boat I would like to know just who of the 'Thor's' complement were below."

"Can you answer that, Mr. Driggs?" demanded Captain Magowan.

Driggs was a bronzed, shrewd-looking man of forty, with a face that looked rather sound and wholesome.

"Yes, sir," replied Driggs, promptly. "Mr. Radwin had volunteered to relieve the man on duty in the engine room. Mr. Radwin was below at the time, sir."

"And who else?"

"No one else at that time, sir."
