“Pep, we met that strange sloop again,” said Jack, and told of what had been said.

“There’s a mystery there, that’s certain,” answered Pepper. “Perhaps we had better report to Captain Putnam.”

“It won’t do any harm.”

“Then come on now. We’ve got ten minutes before parade.”

Captain Putnam’s office was a finely furnished apartment, just off the main classroom. They found the master of the school engaged in writing a letter.

“Well, young gentlemen, what can I do for you?” he said cheerily as they entered.

“We’ve got something to tell you, sir,” they answered, and then Jack quietly related their story.

The master of Putnam Hall listened with close attention, and questioned each one of the party.

“This is certainly odd,” said he, meditatively. “Still, there may be nothing of importance in it. If you see the sloop hovering around again, let me know.”

“We will, sir,” answered Jack, and then he and his companions hurried off.
