Then Cameron built up stone monuments to mark his gold strike. That done, he tarried beside the unconscious Warren. Moments passed--grew into hours. Cameron still had strength left to make an effort to get out of the desert. But that same inscrutable something which had ordered his strange involuntary promise to Warren held him beside his fallen comrade. He watched the white sun turn to gold, and then to red and sink behind mountains in the west. Twilight stole into the arroyo. It lingered, slowly turning to gloom. The vault of blue black lightened to the blinking of stars. Then fell the serene, silent, luminous desert night. Cameron kept his vigil. As the long hours wore on he felt creep over him the comforting sense that he need not forever fight sleep. A wan glow flared behind the dark, uneven horizon, and a melancholy misshapen moon rose to make the white night one of shadows. Absolute silence claimed the desert. It was mute. Then that inscrutable something breathed to him, telling him when he was alone. He need not have looked at the dark, still face beside him. Another face haunted Cameron's--a woman's face. It was there in the white moonlit shadows; it drifted in the darkness beyond; it softened, changed to that of a young girl, sweet, with the same dark, haunting eyes of her mother. Cameron prayed to that nameless thing within him, the spirit of something deep and mystical as life. He prayed to that nameless thing outside, of which the rocks and the sand, the spiked cactus and the ragged lava, the endless waste, with its vast star-fired mantle, were but atoms. He prayed for mercy to a woman--for happiness to her child. Both mother and daughter were close to him then. Time and distance were annihilated. He had faith--he saw into the future. The fateful threads of the past, so inextricably woven with his error, wound out their tragic length here in this forlorn desert. Cameron then took a little tin box from his pocket, and, opening it, removed a folded certificate. He had kept a pen, and now he wrote something upon the paper, and in lieu of ink he wrote with blood. The moon afforded him enough light to see; and, having replaced the paper, he laid the little box upon a shelf of rock. It would remain there unaffected by dust, moisture, heat, time. How long had those painted images been there clear and sharp on the dry stone walls? There were no trails in that desert, and always there were incalculable changes. Cameron saw this mutable mood of nature--the sands would fly and seep and carve and bury; the floods would dig and cut; the ledges would weather in the heat and rain; the avalanches would slide; the cactus seeds would roll in the wind to catch in a niche and split the soil with thirsty roots. Years would pass. Cameron seemed to see them, too; and likewise destiny leading a child down into this forlorn waste, where she would find love and fortune, and the grave of her father.
