“Better save it for morning,” advised Tom. “We’ll need it worse by then.”

The storm still raged, but inside the deserted cabin the boys were fairly comfortable. They had on thick, warm garments, and these, with the glowing fire, made them feel little of the nipping cold that prevailed with the blizzard.

The wind howled down the chimney, scattering the light ashes now and then, and filling the room with the pungent odor of smoke. Around some of the windows, where the rags were stuffed in the broken panes, little piles of sifted snow gathered.

At times the whole frail structure shook with the force of the blast, and at such times the boys would look at each other with a trace of fear on their faces. For the ramshackle structure might fall down on them.

But as it did not, after each recurrent windy outburst, they felt more confident. Perhaps the cabin was built stronger than they thought. The dog showed no uneasiness at these manifestations of Nature. He did not even open his eyes when the wind howled its loudest and blew its strongest. And, too, he seemed to have gotten over the strange fear that caused him to act so oddly.

The other boys had rather laughed at Jack’s “notion” of being “spied upon,” but had they been able to see through the white veil of snow that was falling all about the cabin, they would have realized that there is sometimes something like telepathy, or second sight. For, in reality, the boys were being observed by a pair of evil eyes.

And the evil eyes were set in an evil face, which, in turn belonged to the body of a man who had constructed for himself a rude shelter against the storm.

It was such a shelter as would be hastily built by a hunter caught in the open for the night—a sort of “lean-to,” with the open side away from the direction in which the wind blew. But it could not have been made in this storm, and, consequently, must have been put up before the blizzard began.

The lean-to showed signs of a practiced hand, for it was fairly comfortable, and the man in it chuckled to himself now and then as he looked over toward the deserted cabin.

The man was on the watch, and he had prepared for just this emergency. At times, when he heard the barking of the dog, a frown could have been seen on his face, had there been a light by which to observe it. But the lean-to was in absolute darkness, save what light was reflected by the white snow.
