At sunset the train was ready. Every article that could be dispensed with was left, a rich find for the Indians whose watch fires winked from the hills. To the cry of "Roll out," and the snap of the long whip, the wagon lurched into motion, the thirst-racked animals straining doggedly as it crunched over sage stalks and dragged through powdery hummocks. The old man walked by the wheel, the long lash of his whip thrown afar, flashing in the upper light and descending in a lick of flame on the mules' gray flanks. With each blow fell a phrase of encouragement, the words of a friend who wounds and wounding himself suffers. David rode at the rear with Susan. The two men had told him he must ride if he died for it, and met his offended answer that he intended to do so with sullen silence. In advance, Courant's figure brushed between the bushes, his hair a moving patch of copper color in the last light. Darkness quickly gathered round them. The bowl of sky became an intense Prussian blue that the earth reflected. In this clear, deep color the wagon hood showed a pallid arch, and the shapes of man and beast were defined in shadowless black. In the west a band of lemon-color lingered, and above the stars began to prick through, great scintillant sparks, that looked, for all their size, much farther away than the stars of the peopled places. Their light seemed caught and held in aerial gulfs above the earth, making the heavens clear, while the night clung close and undisturbed to the plain's face. Once from afar the cry of an animal arose, a long, swelling howl, but around the train all was still save for the crackling of the crushed sage stalks, and the pad of hoofs. It was near midnight when Susan's voice summoned Daddy John. The wagon halted, and she beckoned him with a summoning arm. He ran to her, circling the bushes with a youth's alertness, and stretched up to hear her as she bent from the saddle. David must go in the wagon, he was unable to ride longer. The old man swept him with a look of inspection. The starlight showed a drooping figure, the face hidden by the shadow of his hat brim. The mules were at the limit of their strength, and the old man demurred, swearing under his breath and biting his nails. "You've got to take him," she said, "if it kills them. He would have fallen off a minute ago if I hadn't put my arm around him." "Come on, then," he answered with a surly look at David. "Come on and ride, while the rest of us get along the best way we can." "He can't help it," she urged in an angry whisper. "You talk as if he was doing it on purpose." David slid off his horse and made for the wagon with reeling steps. The other man followed muttering. "Help him," she called. "Don't you see he can hardly stand?" At the wagon wheel Daddy John hoisted him in with vigorous and ungentle hands. Crawling into the back the sick man fell prone with a groan. Courant, who had heard them and turned to watch, came riding up.
