"He’s a bigger man," mused "Doc"; "and yet he seems more than half afraid of Sandy. Wonder what the trouble is."

That night the wind changed, the temperature dropped, and the next morning snow began to fall, lightly, however. Again and again Ross went out for trial trips on the fast freezing crust, but not until afternoon did he venture on the journey to the cliff.

The shack stood among the trees on the mountainside about ten feet above the level of the cañon. Taking with him a long pole with a sharpened end, which he found in the shack, Ross slid from tree to tree until he gained the level of the cañon. Then, hugging the foot of the mountain closely, that he might judge of the lay of the land by the trees, and so avoid the dreaded creeks and gorges, he turned down the cañon toward the cliff.

It was difficult walking, the crust being smooth and slippery. Several times one foot broke through, and each time Ross’s heart seemed to rise in his throat when he considered that he was walking on a body of snow deeper than he was high. The cañon had no distinguishing features. It might have been any one of a dozen located among the Shoshones, and all of them unfamiliar to the young man lost in their midst. On either side, the mountains, dreary and lonely and lifeless, arose precipitately. It was windless in the cañon, but on top of the mountains a white, cold cloud of snow played perpetually.

But Ross’s eyes were eagerly searching the mountain at the left for the cliff; and presently he recognized it despite the curtain of snow drifting across its face. There it was, stretching up until his neck ached in the effort to scan the top, where in an unbroken line along the edge hung a great body of snow, the undisturbed accumulations of the last blizzard. The steep side of the cliff, however, was bare, and Ross failed to discover a rope dangling over its surface.

THE SNOW HID IT FROM VIEW

He thought he had not expected to see it there, and so could not account for the sinking of his heart when he found it gone. For a few moments he stood looking down the cañon hemmed in by its great mountain barriers. He fully realized the fact that he was a prisoner within those barriers, perfectly helpless until released by the brief summer.

With bent head he turned his back to the cliff and cautiously retraced his steps while a wildly whirling "squall" suddenly caught him in its clutches. He had gone but a short distance before a sound in the rear caused him to wheel about and listen sharply. Only a smother of snow, swirling up the cañon, met his eyes and a blast of the rising wind his ears. Hesitating, he struggled back a few steps and turned his face up toward the cliff. The snow hid it from view. He stood listening again, and, presently, the sound, above him and a little in advance, again mingled with the roar of the wind. Ross broke into a run, panting through the storm, breaking through the crust, struggling to his feet and tumbling on again. It was certainly the call of a human voice, although no words were distinguishable because of the noise of the wind.
