“I wonder what Hanleigh was doing on the island, anyway.”
“I’ll bet he was up to no good,” said Joe. “Well, we won’t worry about him. He won’t trouble us.”

“Looks as if some one is here ahead of us.”
“Where?”
Frank pointed to the little bay where they had landed on their previous visit. A white-sailed object was clearly outlined against the dark background of trees.
“Another ice-boat!”
Joe gazed at the strange craft in consternation.
