The scenery changed to mountains. There were barren, sublime, awful peaks to the right and left. To the girl's eyes they were beautiful, for she trusted that Thurstane beheld them. She was always on horseback now, scanning every feature of the landscape, searching of course for him. She did not pass a cactus, or a thicket of mezquit, or a bowlder without anxious examination. She imagined herself finding him helpless with hunger, or passing him unseen and leaving him to die. She was so pale and thin with constant anxiety that you might have thought her half starved, or recovering from some acute malady. About five one afternoon, as the train was approaching its halting-place at a spring on the western side of the pass, Clara's feverish mind fixed on a group of rocks half a mile from the trail as the spot where she would find Thurstane. In obedience to similar impressions she had already made many expeditions of this nature. Constant failure, and a consciousness that all this searching was folly, could not shake her wild hopes. She set off at a canter alone; but after going some four hundred yards she heard a gallop behind her, and, looking over her shoulder, she saw Coronado. She did not want to be away from the train with him; but she must at all hazards reach that group of rocks; something within impelled her. Better mounted than she, he was soon by her side, and after a while struck out in advance, saying, "I will look out for an ambush." When Coronado reached the rocks he was fifty yards ahead of Clara. He made the circuit of them at a slow canter; in so doing he discovered the starving and fainted Thurstane lying in the high grass beneath a low shelf of stone; he saw him, he recognized him, and in an instant he trembled from head to foot. But such was his power of self-control that he did not check his horse, nor cast a second look to see whether the man was alive or dead. He turned the last stone in the group, met Clara with a forced smile, and said gently, "There is nothing." She reined up, drew a long sigh, thought that here was another foolish hope crushed, and turned her horse's head toward the train. CHAPTER XXXIII. The tread of Coronado's horse passing within fifteen feet of Thurstane roused him from the troubled sleep into which he had sunk after his long fainting fit. Slowly he opened his eyes, to see nothing but long grasses close to his face, and through them a haze of mountains and sky. His first moments of wakening were so far from being a full consciousness that he did not comprehend where he was. He felt very, very weak, and he continued to lie still.
