The white, scarred face of the mountain looked straight east, over a vast basin of tumbled, lesser hills, dim black forests, and steel-blue loops of a far-winding water. Here and there long, level strata of pallid mist seemed to support themselves on the tree-tops, their edges fading off into the startling transparency that comes upon the air with the first of dawn. But that was in the lower world. Up on the solitary summit of White Face the daybreak had arrived. The jagged crest of the peak shot sudden radiances of flame-crimson, then bathed itself in a flow of rose-pinks and thin, indescribable reds and pulsating golds. Swiftly, as the far horizon leapt into blaze, the aerial flood spread down the mountain-face, revealing and transforming. It reached the mouth of a cave on a narrow ledge. As the splendor poured into the dark opening, a tawny shape, long and lithe and sinewy, came padding forth, noiseless as itself, as if to meet and challenge it. Half emerging from the entrance upon the high rock-platform which formed its threshold, the puma halted, head uplifted and forepaws planted squarely to the front. With wide, palely bright eyes she stared out across the tremendous and mysterious landscape. As the colored glory rushed down the mountain, rolling back the blue-gray transparency of shadow, those inscrutable eyes swept every suddenly revealed glade, knoll, and waterside where deer or elk might by chance be pasturing. She was a magnificent beast, this puma, massive of head and shoulder almost as a lioness, and in her calm scrutiny of the spaces unrolling before her gaze was a certain air of overlordship, as if her supremacy had gone long unquestioned. Suddenly, however, her attitude changed. Her eyes narrowed, her mighty muscles drew themselves together like springs being upcoiled, she half crouched, and her head turned sharply to the left, listening. Far down the narrow ledge which afforded the trail to her den she had caught the sound of something approaching. As she listened, she crouched lower and lower, and her eyes began to burn with a thin, green flame. Her ears would flatten back savagely, then lift themselves again to interrogate the approaching sounds. Her anger at the intrusion upon her private domain was mixed with some apprehension, for behind her, in a warm corner of the den, curled up in a soft and furry ball like kittens, were her two sleeping cubs.
