On the southern slope of a foothill where the snow lay less deep than on the northern and eastern exposures, Kate stood on the sunny side of a brown boulder leaning her shoulder against it as she watched the sheep below her nibbling at the spears of dried bunch grass which thrust themselves above the surface. Her rifle stood against a rock where she could reach it easily, and her horse fed near her, pawing through the snow, like an experienced "rustler." She was dressed to meet the weather in boys' boots and arctics, woolen mittens, riding skirt of heavy blue denim, the fleece-lined canvas coat of the sheepherder, and a coonskin cap with ear-laps. Her face wore an expression that was both sad and troubled as she mechanically watched such sheep as showed a disposition to stray, and kept an eye out for coyotes. Save in her sleep, her quarrel with Mormon Joe had not been out of her mind since, three days before, she had stood shivering at the door and watched him vanish through the sagebrush. Now, in addition, she was worried over his absence. She had kept supper waiting until long after her usual bedtime and to-day she had worn a trail to the top of the hill, watching, and still had seen no sign of him. Poignant regret for what she had said and shame for her ingratitude overwhelmed her. Along with the feelings was a fear lest he refuse to forgive her and insist upon her leaving. Then, too, there was her promise to Mrs. Toomey. Kate was confronted with her first problem. She had threshed it out, turned it over and over, finally arriving at the conclusion that she must keep her promise at any cost to herself. A promise was a promise, and she had given her hand on it. Her regard for her word was a dominant trait in Kate. Mormon Joe had fostered this ideal by words and his own example. So she had slowly made up her mind that having given her word she would not recall it, though it would be a high price to pay for a principle if it cost her his friendship and protection. Kate intended to plead with him; to beg his forgiveness upon her knees, if necessary; to put her arms about his neck and make him understand how much she loved him. She had taken everything for granted heretofore, as her right because he had given it so readily, but all would be different if only he would forget what she had said and give her another opportunity, and if he would let her keep her promise to Mrs. Toomey she would herd sheep until she had saved the amount in a herder's wages. This was her plan after sleepless hours and three days of thinking. Until their quarrel Kate never would have doubted that she could have her way without much difficulty, but then she had not met the cool polite stranger with the adamant beneath his polished exterior. The girl wondered if the whimsical unselfish friend and comrade ever would come back to her. The doubt of it set her chin quivering.
