"We've hit something," Bob laughed as he jumped from the boat and as the next wave hit, pulled it up a little farther.

"What part of the world do you suppose this is?" Jack asked as he tried in vain to pierce the fog.

"I imagine it's our island all right. We surely didn't go far enough to hit anything else. But I think I feel a little breeze and it'll probably blow the fog away pretty soon."

He was right for, in a very few minutes, the fog began to lighten and in another fifteen minutes it was practically gone.

"They sure come quick and go quick," Jack declared. "Do you recognize the place?"

"I think so. That's the grove where we heard the wild man of Borneo or whatever it was."

"Then we're away round the other end from the boat?"

"I reckon that's it, and we'd better be moving. Uncle Si'll be worried stiff about us."

"Going to row?"

"Of course. There's no use in leaving the boat here. Help me get her in the water."
