“Come back!” added Ritter and Coulter.

“Not to-night!” answered Pepper, grimly. “Maybe we’ll see you in the morning.”

“If you don’t come back, I’ll get square, remember that!” yelled Ritter, in a rage.

“See you to-morrow,” sang out Andy.

The rocks upon which the sloop had struck were several in number and were backed up by a small island situated a hundred feet or more from the shore. Peering into the gloom those on the craft saw the others wade out of the water to the island.

“They are safe,” said Pepper. “But they are a good mile and a half from Putnam Hall.”

“And they can’t get ashore without swimming,” added Andy. “But as their clothing is already wet, that won’t hurt them much.”

“What scoundrels they are—to want to injure this boat!”

“That’s true. We really ought to report them to Captain Putnam and have them expelled.”

“We might do that if it wasn’t for one thing. Remember, we have no right to be away from the school to-night. We should have obtained permission to watch the sloop.”
