She had removed her hat, fancying that already the earth was throwing off its heat, that a little coolness and freshness was coming down to meet her from the mountains. She turned her eyes toward them and it was then, just after the sunset, that she saw a man riding toward her. He was still far off when she first glimpsed him, just cresting one of the higher hills, so that for him the sun had not yet set. For she caught the glint of light flaming back from the silver chasings of his bridle and from the barrel of the gun across the hollow of his left arm. She did not believe that he had seen her in the shadow of the cottonwoods. If she went on she must meet him presently. She glanced back over her shoulder, noting how far she had come from the town. It was very still again; the bell had ceased its complaint; the hoofs of the approaching horse seemed shod with felt, falling upon felt. She swung about and walked back toward San Juan. A little later she heard the man's voice, calling. Clearly to her, since there was no one else. Why should he call to her? She gave no sign of having heard, but walked on a trifle faster. She sensed that he was galloping down upon her; still in the loose sand the hoof-beats were muffled. Then when he called a second time she stopped and turned and waited. A splendid big fellow he was, she noted as he came on, riding a splendid big horse. Man and beast seemed to belong to the desert; had it not been for the glint of the sun she realized now, she probably would not have distinguished their distant forms from the land across which they had moved. The horse was a darkish, dull gray; the man, boots, corduroy breeches, soft shirt, and hat, was garbed in gray or so covered with the dust of travel as to seem so. "What in the world are you doing way out here?" he called to her. And then having come closer he reined in his horse, stared at her a moment in surprised wonderment, swept off his hat and said, a shade awkwardly: "I beg pardon. I thought you were some one else." For her wide hat was again drooping about her face, and he had had just the form of her and the white skirt and waist to judge by. "It is all right," she said lightly. "I imagined that you had made a mistake."
