Hour after hour they moved, Keith all the time keeping a sharp look-out for signs to show where the dog had taken his trail. Tracks of various kinds were plentiful, crossing and re-crossing one another in the most confusing manner. It was certainly a puzzling task to choose the ones which would lead him to his destination.

Slowly he proceeded, peering here and there for some solution of the mystery. In this manner he had advanced a considerable distance, when the whining of the dog caused him to glance back. The animal had stopped, and seemed to be in trouble, looking first at the man, and then away to the left. Wondering what was the matter, Keith returned to the spot.

"Well, doggie," he exclaimed, "what's wrong?"

But the cur continued to whine, looking alternately to the left and up into the man's face.

Suddenly a thought flashed into Keith's mind. Perhaps the brute was calling his attention to the right trail. It was worth investigating at any rate.

The dog seemed to read his thoughts, and, weak though he was, gave a joyful bark, and bounded off in the direction toward which he had been looking.

"There's something in this after all," mused Keith, as he followed hard after.

Away in the distance a range of mountains stood out bold and austere against the sky. At a certain place a break appeared, one of Nature's vast passes, and toward this the dog made his way. Ahead lay a large, open plain, devoid of trees. Across this they travelled to a forest beyond, which clothed the base of the mountains. The trees were large and resembled a vast, silent army wedged into the valley, as if forbidding any progress that way.

But the dog was not thinking of the trees, nor how grand they looked in their soft, snowy mantle. He had something else on his mind, and with firm assurance he nosed his way into their sombre depths.

For two hours they threaded the forest, up the long, winding valley, when at length a log cabin burst suddenly into view. It was small, low, and evidently had been built for some time. A stream of smoke, curling into the frosty air, betokened life within. Around the building many tracks of animals were visible, while here and there human footprints could be discerned.
