"We want to know where the treasures are on the islands," remarked George.

"Then, there is another thing," ventured Harry. "I don't think all the boats of our ship were lost, and it is likely that they found refuge on some other island."

"But how do you know there are other islands near here?" asked the Professor.

"Well, I don't know, only from what John has said."

John looked at Harry for a moment quizzically, and then said: "When did I say so?" he asked with a smile.

"When you told about the charts of the treasure caves."

"But we have found them, haven't we?"

"Yes; but not all of them."

"That is true; and your argument is correct. Unquestionably, there are other islands, probably not in the immediate vicinity, but near enough that they could have caught some of the boats. I quite agree with you that we ought to make the attempt. The Professor and I have just been talking of taking up the matter in order to relieve any who might have been so unfortunate as to be east away."

"I am surprised," said the Professor, "that you[p. 29] are not through with treasure hunting, and want some more of it."
