"I certainly would not," said Jack firmly.
"Very well, then," said Secretary Daniels. "I'll set your mind at rest. Your suggestions shall be followed out. I'll give the necessary directions the first thing in the morning."
"In the morning, sir?" repeated Jack. "The morning may be too late."
"Oh, I guess not," Secretary Daniels smiled. "It has been three weeks or more since your first warning and nothing has happened. I guess we can safely depend upon being let alone a few hours after the second warning."
Jack was about to protest, thought better of it and said simply:
"Very well, sir."
A moment later the lads took their departure with the ambassador. In the seclusion of the latter's automobile, Jack said:
"I can't see how the secretary dares let time slip by like that."
"Never mind," said the ambassador, "you'll find in a day or two that Secretary Daniels knows what he's doing. Don't make any mistake about him. He's a capable man."
"I have no doubt of that, sir," replied Jack. "But if he had seen three years of war, as we have, he would never delay. Besides, he doesn't know these German submarines as well as I do. Neither do any of the Americans."
