Darrin had already looked out over the sea, but he had been unable to make out any sign of the presence of a submarine.
"Could it have been a mine?" demanded Mr. Launce.
"No, sir," Dave answered, promptly. "Had we struck a mine the explosion would have been much more violent."
"Then a torpedo provides sufficient experience of this sort of thing," cried Mrs. Launce, making a face.
"Der passengers vill my boat go in!" called Captain Kennor. "Dere vill time be."
Again Mrs. Launce glanced inquiringly at Darrin, who nodded his confirmation.
Three boats were cleared away, carrying most of the crew and all the officers except the master. The boats were safely launched, and fortunately the sea was not too rough for them.
Then Captain Kennor appeared, carrying a bag and his navigating instruments.
"Are your ship's papers and instruments intended for the Germans, sir?" Dave inquired, significantly.
"No; you be right," admitted Captain Kennor, opening his eyes wide, after a brief moment's thought.
