"I presume," Sam went on, "that my coming on board in shabby clothes, and as an object of charity, convinced Jamison that I wasn't worth searching. I saw him looking me over, though!"

"Object of charity—not!" returned Frank. "We're mighty glad you're with us right now! You say he's taking us to the Barren islands. Well, we wouldn't know the Barren islands from any other place without you. You've put us on our guard, at least, and that's worth more than the price of the ticket! We're glad of your company, too!"

"Now, see here, boys," Tommy whispered, "we mustn't let this man Jamison know that we have discovered that we have been robbed. The minute he knows that we are suspicious of him, the matter will come to a focus immediately. We've got to have time to think this matter over before anything is done."

This plan of action was agreed to, and the boys sat for some minutes in silence. After a time Jamison came to where they were seated, just at the doorway of the trunk cabin, and began asking questions about the need for a doctor. Tommy explained that a member of their party had been injured by a fall, and that they were going to Cordova in quest of a surgeon. He again asked Jamison to put on full speed.

"There's a man over here on the coast, this side of Katalla, who is said to be a fine surgeon," Jamison explained, after Tommy had finished his statement. "He's a sort of a recluse, people say, and lives alone in a shabby hut, high up above the tide. You might stop and consult him. That would be better, it seems to me, than going away up to Cordova. Still," he went on with a grim smile, "I've been paid to take you to Cordova and back, and, if you insist, I mean to live up to my bargain!"

Sam gave Frank a quick poke in the ribs and whispered in his ear:

"Yes, he does!"

"Let him play out his string," whispered Frank in return.

"This surgeon," Jamison went on, "is a queer old fellow. Sometimes he'll take a case, and sometimes he won't. If he feels in an ugly mood, he's likely to kick us out of his cabin."

Tommy listened with apparent interest to what the treacherous Jamison was saying, but it is needless to remark that he did not accept it as truth. It was his belief that the fellow was manufacturing a pretext for getting himself and his friends quietly on shore as soon as one of the Barren islands was reached.
