A deepening rose color over the eastern horizon appeared to be reflected upon the mountain peaks, and this glow crept down the dark slopes. Gray dawn changed to radiant morning with an ethereal softness of color. When the blazing disk of the sun shone over the ramparts of the east all that desert world underwent a wondrous transfiguration. The lord of day had arisen and this was his empire. Red was the hue of his authority, emblazoned in long vivid rays over the ranges and the wastelands. Then the great orb of fire cleared the horizon and the desert seemed aflame. One moment Adam gave to the marvel and glory of the sunrise, and then he looked no more. That brief moment ended in a consciousness of the gravity of his flight. For the first touch of sun on face and hands burned hot, as if it suddenly aggravated a former burn that the night had soothed. “Got to reach--river soon,” he muttered, thickly, “or never will.” He walked on while the sun climbed. Desert vegetation increased. Adam toiled on, breathing hard, careless now of the reaching thorns and heedless of the rougher ground. He was perfectly conscious of a subtle changing of his spirit, but because it seemed a drifting farther and farther from thought he could not comprehend it. Courage diminished as fear augmented. More and more his will and intelligence gave way to sensorial perceptions. More and more he felt the urge to hurry, and, though reason warned against the folly of this, it was not strong enough to compel him to resist. He did hurry more and stumbled along. Like breath of a furnace the heat rose from the rocky, sandy soil; and from above there seemed to bear down the weight of the leaden fire. His skin became as dry as dust and began to shrivel. It did not blister. The pain now came from burn of the flesh underneath. He felt that his blood was drying up. A stinging sensation as of puncture by a thousand thorns throbbed in his face and neck. The heat burned through his clothes, and the soles of his boots were coals of fire. Doggedly he strove forward. A whistle accompanied his panting breaths. Most intolerable of all was thirst--the bitter, astringent taste in the scant saliva that became pasty and dry, the pain in his swelling tongue, the parched constriction in his throat. At last he reached the base of a low rocky ridge which for long had beckoned to him and mocked him. It obstructed sight of the slope to the mountain range. Surely between that ridge and the slope ran the river. The hope spurred him upward.
