his laugh ringing in her ears. Did she only imagine a mockery in it? Was there any reason to believe a word this man said? She appeared as helpless to see through him as she was in her predicament. They had entered a cañon, such as was typical of that mountain range, and the winding trail which ran beneath the yellow walls was one unused to travel. Joan could not make out any old tracks, except those of deer and cougar. The crashing of wild animals into the chaparral, and the scarcely frightened flight of rabbits and grouse attested to the wildness of the place. They passed an old tumbledown log cabin, once used, no doubt, by prospectors and hunters. Here the trail ended. Yet Kells kept on up the cañon. And for all Joan could tell the walls grew only the higher and the timber heavier and the space wilder. At a turn, when the second pack-horse, that appeared unused to his task, came fully into Joan's sight, she was struck with his resemblance to some horse with which she was familiar. It was scarcely an impression which she might have received from seeing Kells's horse or Bill's or any one's a few times. Therefore she watched this animal, studying his gait and behavior. It did not take long for her to discover that he was not a pack-horse. He resented that burden. He did not know how to swing it. This made her deeply thoughtful and she watched closer than ever. All at once there dawned on her the fact that the resemblance here was to Roberts's horse. She caught her breath and felt again that cold gnawing of fear within her. Then she closed her eyes the better to remember significant points about Roberts's sorrel—a white left front foot, an old diamond brand, a ragged forelock, and an unusual marking, a light bar across his face. When Joan had recalled these, she felt so certain that she would find them on this pack-horse that she was afraid to open her eyes. She forced herself to look, and it seemed that in one glance she saw three of them. Still she clung to hope. Then the horse, picking his way, partially turning toward her, disclosed the bar across his face. Joan recognized it. Roberts was not on his way home. Kells had lied. Kells had killed him. How plain and fearful the proof! It verified Roberts's gloomy prophecy. Joan suddenly grew sick and dizzy. She reeled in her saddle. It was only by dint of the last effort of strength and self-control that she kept her seat. She fought
