"I'm sure you have," said the boy, thinking that it was time he let these mysterious parties know that he seriously objected to being set upon, pulled down, and roughly treated, just as though he were a common criminal.

"Well, this is a joke on us, sure enough," remarked the man who gave orders; "let him up, Jenkins; it must be one of the boys we saw through the glasses yesterday camped at the foot of the island. They didn't go back home after all, as we believed, when we came back here with a boat this evening. That must have been another lot we heard coming down the river."

Max began to grasp things now. From these words he knew that these two men must be the same whom Steve had seen watching the island on the day before, and who had appeared to go away up the river. They must have circled around, so as to finally reach Carson, where they heard certain things that had sent them up again, this time in a boat, late the afternoon before.

And hearing the splash of oars as Ted and his cronies hurried back to town, they had believed that the boys were those whom they had seen camped at the lower end of the island. Doubtless they even suspected that Max and his chums might have been also frightened off by the same wild-looking man who had appeared to Herb Benson weeks ago.

"Who are you, and what are you looking for over here on Catamount Island?" Max now asked, boldly, feeling pretty sure he could give a good guess, even before the other spoke a word in explanation.

The crackle of a match told him that the leader of the couple wished to take a look at him, so as to be satisfied. And when the little piece of wood flared up, Max was able to see that both men were, as Steve had declared, dressed in gray uniforms, that were decorated with the brass buttons of authority.

"Well, it is a boy, as sure as anything, Jenkins," remarked the man, who wore a short-pointed beard, and had a keen face, as though he might be in the habit of dealing with charges who required constant vigilance. "Now, I hope my assistant didn't hurt you much when he jumped you, following my orders, when he heard you coming?"

Now, Max did feel a trifle sore, where he had struck the ground with the said Jenkins on top of him; and doubtless the feeling would be still more pronounced by another day. But then he was too proud to confess to any such small thing.

"Nothing to mention, sir," he remarked, just as though it were a common thing to have people wallow all over him, as though they were playing tackle in a football struggle. "But are you looking for a lunatic?"

"Hello! Do you mean to say you can put us on the track of one?" demanded the man who had been called Mr. Lawrence by his assistant.
