Bob told him it was the biggest mix-up he had ever seen, and Bob had ridden the range in every State where beef grows wild. He was in the thickest of the huddle, was Bob, working as if he did not know the meaning of fatigue. Thurston, watching him thread his way in and out of the restless, milling herd, only to reappear unexpectedly at the edge with a steer just before the nose of his horse, rush it out from among the others--wheeling, darting this way and that, as it tried to dodge back, and always coming off victor, wondered if he could ever learn to do it. Being in pessimistic mood, he told himself that he would probably always remain a greenhorn, to be borne with and coached and given boy's work to do; all because he had been cheated of his legacy of the dim trails and forced to grow up in a city, hedged about all his life by artificial conditions, his conscience wedded to convention. CHAPTER VI. THE BIG DIVIDE The long drive was nearly over. Even Thurston's eyes brightened when he saw, away upon the sky-line, the hills that squatted behind the home ranch of the Lazy Eight. The past month had been one of rapid living under new conditions, and at sight of them it seemed only a few days since he had first glimpsed that broken line of hills and the bachelor household in the coulee below. As the travel-weary herd swung down the long hill into the valley of the Milk River, stepping out briskly as they sighted the cool water in the near distance, the past month dropped away from Thurston, and what had gone just before came back fresh as the happenings of the morning. There was the Stevens ranch, a scant half mile away from where the tents already gleamed on their last camp of the long trail; the smoke from the cook-tent telling of savory meats and puddings, the bare thought of which made one hurry his horse. His eyes dwelt longest, however, upon the Stevens house half hidden among the giant cottonwoods, and he wondered if Mona would still smile at him with that unpleasant uplift at the corner of her red mouth. He would take care that she did not get the chance to smile at him in any fashion, he told himself with decision. He wondered if those train-robbers had been captured, and if the one Park wounded was still alive. He shivered when he thought of the dead man in the aisle, and hoped he would never witness another death; involuntarily he glanced down at his right stirrup, half expecting to see his boot red with human blood. It was not nice to remember that scene, and he gave his shoulders an impatient hitch and tried to think of something else.
