“It is the one from the club house all right,” David declared. “I wonder how it got over here?”

“Look,” Carol murmured, “do you see something moving on the island?”

“You are seeing things,” Janet declared.

“I mean—look in that tree right opposite from us. I can just faintly see something—looks like a flag being waved.”

“Perhaps it is Gale and Bruce,” Janet said excitedly. “Get a boat. We’ll go over and find out.”

David departed to find a friend who could lend him a motor boat. The fifteen minutes it took him were interminable for those waiting.

When the boat put out from the mainland Bruce half slid, half climbed down from the tree and together he and Gale went down to the beach to await their rescuers.
