"I think so, too," broke in Jack, "We know that they are criminals and what were they doing round here if they weren't up to some such job? You see," he continued, as his father was about to speak, "they didn't come here after those cells, because they didn't know anything about them till they saw the boat the day of the race. I believe they intended to rob the bank in the first place and then they saw our boat and thought that if they could get hold of our secret, it would pay them better than this job. That's the way I've got it doped out."

"And I believe Jack's right, dad," broke in Bob. "Something I heard that man Reed say just after they got me in the car that night has just come to me. I didn't think much of it at the time; it has never occurred to me till just now."

"What was it?" eagerly asked Mr. Golden.

"Why, we had gone but a little ways when I heard Reed say, in a low voice. 'How about that other job, Bill?' and King replied angrily, 'Shut up, you fool!' Then as Reed started to say something, he whispered, 'That can wait awhile; it won't spoil.'"

"I really believe the boys are right," declared Uncle Ben. "There is little doubt in my mind that when you get those two men you will have the robbers of this bank."

"I'll tell you what," broke in Bob, "if those two fellows did it, I'll bet a cent they'll go straight to the place where they took me, that we found yesterday. You see they think no one knows about it and that they will be safe there."

"Then we'd better get some officers and get after them as quickly as possible," declared Uncle Ben.

"I guess we might as well try it," assented Mr. Golden, "seeing it's the only clue we have. Mr. Riggs, see if Mr. Switzer is out there and if he is, have him come in, will you?"

The cashier disappeared, but was back almost immediately, followed by a powerfully built man about forty years old, the chief of police of Skowhegan.

"Hello, Switzer, glad you were at hand," cried Mr. Golden.
