"But I do not see," observed George, "what the copper in the cave had to do with the town?"
"Nor do I," responded Harry. "Suppose we see John at the first opportunity. There are other things besides the copper I would like to know. John has asked every one that he has come into contact with about the different wrecks that have come ashore within the past two years, and no one seems to have any idea that more than two of the Investigator's boats came ashore."
"Well, if they did it isn't at all likely that they could come to the southern shore, when the wrecked vessel was to the north of the island."
"It is just for that reason," responded George, "that I believe we shall find other islands in the vicinity, and who knows but some of the boats reached those islands?"
"I am with you," said Harry. "Shall we talk to John about it?"
"By all means. But stop! Why not have a talk with the Professor first?"
"Good idea. We owe everything to him."
