"Did you come aboard from the submarine?" questioned the gunboat's commander, wheeling upon Jack Benson.

"Yes, sir."

"Ahoy, 'Massapequa,'" floated up in Ennerling's tones. "Is that you, Braylesford?"

"Aye, Ennerling, and a shabby old trick you've played on us!"

Commander Ennerling's hearty laughter came up from below.

"Captain John Benson, the young man who came over your stern rail, is the genius who planned the joke," called up Ennerling.

"But with your approval, eh?"

"Of course, Braylesford."

"Then, Ennerling, I'm sorry I can't have the pleasure of putting you in irons," nodded Lieutenant Commander Braylesford, dryly.

"Let down a rope ladder, and I'll come aboard for a moment, Braylesford."
