"But if you give me any trouble, Clip," Bob added, seriously, "I may have to put you ashore, and let you walk home."

Clip gave the most emphatic assurance of good conduct, and was informed that he could go.

There was much to do, even on the last morning, and though the boys were early risers, it was fully ten o'clock before they were ready to start.

Half an hour before this Bob had a surprise.

Sam Wolverton was seen approaching on a run, breathless and without a hat. He arrived at the landing, just as Bob was putting off in the flat-bottomed boat, with a load of provisions for the voyage.

"What on earth is the matter, Sam?" asked Bob, in surprise.

"Let me get on the boat and I will tell you."

The boat was put back and Sam jumped on.

"Now what has happened, Sam?"

"Do you see this," said Sam, pointing to his right cheek, which was stained with blood.
