"Mr. Farnum," broke in Jack Benson, sternly, "that torpedo was fired by design, with intent to sink us!"

"What? Who—"

"I can't make any positive charge," it was Lieutenant Danvers's turn to say. "But I can offer certain evidence that I'll stick to anywhere. Just a few seconds before that torpedo got so close to us I was noting the Rhinds boat, the 'Thor.' Her course was toward us, briefly. Then she turned off on another course."

"Do you mean to say that the Rhinds boat was turned our way at just the time when that torpedo could have left her, headed for us?" demanded Jacob Farnum.

"That's the whole indication," replied Lieutenant Danvers, firmly.

"Then what are we doing, waiting here?" cried the shipbuilder, angrily. "Jack, now that that torpedo is spent, and lying harmless on the water, start up speed and head over that way. Go carefully, for, remember, any sudden shock against the war-head of the torpedo would set it off."

Jack signaled for slow speed ahead, the response coming promptly.

"Somers," directed Lieutenant Danvers, "get the signal bunting out, and I'll help you rig a signal to the 'Oakland.'"

It was the first time, on any of the cruises, that Danvers had attempted to give an order, or to take any part in the handling of the craft. But now he was about to make a serious report, as an officer of the United States Navy.

In a very few moments, Danvers and Somers working together, the necessary flags were out, and knotted to the line in their proper order.
