To her surprise Garnett readily accepted her invitation. While she was setting the table, she kept stealing glances at him, and tried to harmonize her memory of the very boyish person she had met on the train with this quiet young man. He was the same big, friendly fellow, with the same laughter-wrinkled eyes; but now there was something beneath his reserve that she could not quite understand. Sitting cross-legged on the grass outside the tent, he played with 'Thello, and talked casually to Harry while she moved about inside. All the restraint of the first moments had apparently passed; Garnett said nothing more about the horses until he left, an hour later. "If that pony of mine should come in here," he said, turning in his saddle, "I'd be a lot obliged to you if you'd send me a line. Soldier's my post office. That horse of mine is about six years old, sorrel, ring-and-arrow brand. You'd notice him in a bunch of cayuses." A sorrel! Harry's thoughts flashed to the sorrel horse which Rob had ridden away that morning. She felt a pang of vague apprehension, and wondered whether Garnett had noticed her startled look. When Garnett had gone, she tried to reassure herself. Of course anything that Rob took an interest in was all right; but _why did he keep it a secret from her_? Suppose that sorrel horse should prove to have the ring-and-arrow brand? There might be many sorrels with that brand, yet her heart beat more nervously and her lips grew dry. An idea came to her, and she ran up the glen toward the pasture where the colts were hidden. She knew that the sorrel was not there, but she wanted to see whether the colts were branded. When she reached the upper end of the glen she crawled through the barbed wire, and was just emerging from the shelter of the trees when she saw Garnett ride along the fence and look at the bunch of colts inside. Harry stepped back, instinctively afraid of his seeing her. Why? She demanded it of herself fiercely. Why should she feel guilty because Rob was concealing something from her? She had done nothing wrong. But Garnett suspected something; he had not believed her. Humiliation swept over her. Even after Garnett, satisfied that his horse was not there, had ridden away, and after she had returned to the tent, her cheeks burned at the thought, "He did not believe me." She determined to tell Rob about the whole affair and to make him explain the mystery. Also, she would look at the brand on that sorrel horse. But Rob and Jones did not get home until ten o'clock. They were very tired and hungry, and Harry was so busy getting supper for them that she did not have a chance to go into the matter. The next morning Jones rode away on the black horse. When Rob had gone down to the brush to work on the fence, Harry ran out to the corral and looked at the sorrel. The brand was perfectly plain--ring and arrow!
