At first he couldn't believe that it was a track. The reason was simply that the size of the thing was incredible,—as if some one had laid a flour sack in the mud and taken it up again. He did not think of any of the modern-day forest creatures as being of such proportions. It was very stale and had been almost obliterated by many days of sun. Perhaps he had been mistaken in thinking it an imprint of a living creature. He went to his knees to examine it.

But in one instant he knew that he had not been mistaken. It was a track not greatly different from that of an enormous human foot; and the separate toes were entirely distinct. It was a bear track, of course, but one of such size that the general run of little black bears that inhabited the hills could almost use it for a den of hibernation!

His thought went back to his talk with Barney Wegan; and he remembered that the man had spoken of a great, last grizzly that the mountaineers had named "The Killer." No other animal but the great grizzly bear himself could have made such a track as this. Bruce wondered if the beast had yet been killed.

He got up and went on,—farther toward Trail's End. He walked more swiftly now, for he hoped to reach the end of Pine-needle Trail before nightfall, but he had no intention of halting in case night came upon him before he reached it. He had waited too long already to find Linda.

The land seemed ever more familiar. A high peak thrust a white head above a distant ridge, and it appealed to him almost like the face of an old friend. Sometime—long and long ago—he had gazed often at a white peak of a mountain thrust above a pine-covered ridge.

Another hour ended the day's sunlight. The shadows fell quickly, but it was a long time yet until darkness. He yet might make the trail-end. He gave no thought to fatigue. In the first place, he had stood up remarkably well under the day's tramp for no other reason than that he had always made a point of keeping in the best of physical condition. Besides, there was something more potent than mere physical strength to sustain him now. It was the realization of the nearing end of the trail,—a knowledge of tremendous revelations that would come to him in a few hours more.

Already great truths were taking shape in his brain; he only needed a single sentence of explanation to connect them all together. He began to feel a growing excitement and impatience.

For the first time he began to notice a strange breathlessness in the air. He paused, just for an instant, his face lifted to the wind. He did not realize that all his senses were at razor edge, trying to interpret the messages that the wind brought. He felt that the forest was wakening. A new stir and impulse had come in the growing shadows. All at once he understood. It was the hunting hour.

Yet even this seemed familiar. Always, it seemed to him, he had known this same strange thrill at the fall of darkness, the same sense of deepening mystery. The jays no longer gossiped in the shrubs. They had been silenced by the same awe that had come over Bruce. And now the man began to discern, here and there through the forest, queer rustlings of the foliage that meant the passing through of some of the great beasts of prey.

Once two deer flashed by him,—just a streak that vanished quickly. The dusk deepened. The further trees were dimming. The sky turned green, then gray. The distant mountains were enfolded in gloom. Bruce headed on—faster, up the trail.
