"I discovered it to-day by accident. I was standing some distance back on shore when I saw the vessel lying on the water."
"How far from here?"
"Just the other side of the reef."
Jack whistled.
"By Jove! We came awfully close," he said.
"You did indeed," said Cutlip. "But for the reef you must have been discovered. Fortunately, it is very high."
"I suppose the U-Boat is on the surface at this moment," Frank interjected.
"Most likely," Hetherton agreed. "A small crew has probably been left on board, and they more than likely are awaiting the return of their comrades."
"Strange they didn't hear the firing," said Frank.
"Not at all," said Jack. "I heard none of it here."
