"I told you—an island!" cried Bob. "There's something funny about this business."
"How do you mean?"
"I saw Nat change the course of the 'Nimrod' yesterday. He was steering by map and compass and must have known that we were not going all the way across the bay."
"Well?" asked Dave, in puzzled tones; "what of that?"
"I have an idea he dumped us on this island for some purpose."
"But what could it be?" Sam asked.
"I am sure I don't know. Another funny thing was the way our stuff was thrown on shore."
"It's mighty queer," admitted Dave; "I can't make head or tail out of it."
"Ever notice how Nat is always talking about going back to Kingswood?" asked Bob.
"Yes, and kicked, too, about keeping on Clair Bay," added Sam Randall, reflectively.
