"I certainly do," declared Frank, "and we drew straws to see which of us should go. I lost."

"Exactly. Well, when I reached the admiralty I found there a certain Captain Ames. I made myself known and was straightway informed that I would do as well as another. Captain Ames was in command of the British destroyer Falcon. He was bound on active duty at once, and he took me along as second in command."

"Where was he bound?" demanded Frank. "And what was the nature of the work?"

"The nature of the work," said Jack, "was to search out German mines ahead of the battleships, who were to attempt a raid of Heligoland."

"Great Scott!" exclaimed Frank. "I hadn't heard anything about that.
Was the raid a success?"

"It was not," replied Jack briefly.

"Explain," said Frank.

"I'm trying to," smiled Jack. "Give me a chance, will you?"

He became silent and mused for a few moments. Then he said meditatively:

"The destroyer service might well be called the cavalry of the sea. It calls for dashing initiative, aggressiveness and courage and daring to the point of rashness. Where an officer would be justified—even duty bound—by navy standards to run away with a bigger and more valuable vessel, the commander of a destroyer often must close in to almost certain annihilation."
