"That's right," Torry said. "What is the why-for? All naval craft are supposed to be destroyers anyway—I mean service craft."

Morgan was the oracle on this occasion.

"Ikey is right. I've read that torpedo boats antedate the Spanish War. Their exclusive business was to run up close to an enemy battleship and deliver against it an automobile torpedo. These boats were great stuff in the beginning.

"Then they invented a craft as an antidote for the torpedo boat—the torpedo boat destroyer. Our Admiral Sims called this new vessel 'a tin box built around a mighty big engine.'"

"Wow! And he is right," cried Frenchy Donahue. "That's just what our Colodia is."

"And these subchasers are still faster," Torry observed. "They tell me they can make thirty-five, and better, an hour."

"Oi, oi!" cried Ikey Rosenmeyer at this juncture. "Speak of the Old Harry and hear his wings, yet! What's that off yonder?"

The Sue Bridger was now skimming out of the cove, and the fog was lifting. They got a sight of a patch of open sea across which a low, gray vessel was shooting like a shark after its prey.

"What a beaut!" shouted Torry.

"That's one of the new chasers all right," Whistler agreed. "Their base is at New London where the submarine base is."
