He saw a man seated tailor fashion, with his legs crossed, on the hard earthen floor of the cabin. He seemed to be tearing at some food with almost the ferocity of a half-starved dog.

Max looked in vain for the expected and well-known stripes that would distinguish a prison convict. This man did not wear anything of the sort. His garments were of a very ordinary kind, though just now exceedingly ill kept, from groveling in the dirt, and sleeping night and day without taking them off.

His hair seemed to be rather long and unkempt, while there was a wild look in his face; and the way he cast his staring eyes about sent a cold chill into the heart of the watching lad.

Max realized that after all he and his chums had made a very poor guess of it, when they tried to figure things out. But he also felt a little satisfaction when he remembered how he had declared the footprint was made by a common shoe, such as inmates in all public institutions wore, as they are made in prisons by those who are serving long sentences.

This wretched man, then, was no escaped convict; but he was undoubtedly a crazy being, who, having fled from some retreat, thought to elude recapture by hiding in this lonely place!

Max hardly knew what to think. The change was so complete that he felt as though he must alter his plans in accordance with the new line-up. It would have been all right for the boys to help recapture a desperate criminal, whose being at large was a constant menace to the peaceful community; but would the same apply when it was a lunatic who kept house in that strange cabin on Catamount Island?

No matter what he decided, he must make his mind up quickly. The man looked very dangerous, though Max knew that appearances are very deceptive when those who are out of their right minds are concerned. Often the very man who seems most harmless is the crafty one ready to commit a terrible deed; while he who looks to be a veritable terror may turn out to be a mild fellow, who would not harm an ant.

Rapidly he ran things over in his mind. Why, evidently anyone devoid of sense and reason had no right to be at large. While he might manage to live through the summer, by snaring birds and catching fish, what would happen to the poor fellow when the biting blasts of bitter winter swept down from the cold Northland!

No matter who he was, where he came from, and what his object in hiding here might be, it were better that his presence be made known to the authorities. Somewhere or other they must be looking for him, since even the helpless inmates of public institutions for the insane are objects of concern; and one of them at large will create a reign of terror in a community, especially among the women.

"I must do it!" Max was saying to himself, as he continued to watch the wretched man tear away at the food, and act as though he were a wild beast rather than a human being, once gifted with a mind that could reason, love, hate, and learn.
