The next moment he was making his way up the gully's side, and soon a triumphant shout announced that he had reached the road and was off for the lumber camp at his best speed.
The task before him was one from which many a grown man might have shrunk in dismay. For five long, lonely miles the road ran through the forest that darkened it with heavy shadows, and not a living soul could he hope to meet until he reached the shanty.
It was now past eight o'clock, and to do his best it would take him a whole hour to reach his goal. The snow lay deep upon the road, and was but little beaten down by the few sleighs that had passed over it. The air was keen and crisp with frost, the temperature being many degrees below zero. And finally, the most fear-inspiring of all, there was the possibility of wolves, for the dreaded timber wolf had been both heard and seen in close proximity to the camp of late, an unusual scarcity of small game having made him daring in his search for food.
But Frank possessed a double source of strength. He was valiant by nature, and he had implicit faith in God's overruling providence. He felt specially under the divine care now, and resolutely putting away all thoughts of personal danger, addressed himself, mind and body, to the one thing—the relief of Johnston from his perilous position.
With arms braced at his sides and head bent forward, he set out at a jog-trot, which was better suited for getting through the deep snow than an ordinary walk. Fortunately he was in the very pink of condition. The steady, hard work of the preceding months, combined with the coarse but abundant food and early hours, had developed and strengthened every muscle in his body and hardened his constitution until few boys of his age could have been found better fitted to endure a long tramp through heavy snow than he. Moreover, running had always been his favourite form of athletic exercise, and the muscles it required were well trained for their work.
"I'll do it all right inside the hour," he said to himself. And then, as a sudden thought struck him, he gave a nervous little laugh, and added, "And perhaps make a good deal better time if I hear anything of the wolves."
Try as he might, he could not get the wolves out of his head. He had not himself seen any signs of them, but several times the choppers working farthest from the camp had mentioned finding their tracks in the snow, and once they had been heard howling in the distance after the men had all come into the shanty for the night.
On he went through the snow and night, now making good progress at his brisk jog-trot, now going more slowly as he dropped into a walk to rest himself and recover breath. Although the moon rode high in the heavens, the trees which stood close to the road allowed few of her beams to light his path.
"If it was only broad daylight I wouldn't mind it a bit," Frank soliloquized; "but this going alone at this time of night is not the sort of a job I care for."
And then the thought of poor Johnston lying helpless but uncomplaining in the snow made him feel ashamed of his words, and to ease his conscience he broke into a trot again. Just as he did so a sound reached his ear that sent a thrill of terror to his heart. Hoping he might be mistaken, he stopped and listened with straining senses. For a moment there was absolute silence. Then the sound came again—distant, but clear and unmistakable. He had heard it only once before, yet he felt as sure of it now as if it had been his mother's voice. It was the howl of the timber wolf sounding through the still night air from somewhere to the north; how far away he could not determine.
