As Buck rode off he heard Miss Thorne ask if there wasn't something she could do. Lynch's reply was indistinct, but the tone of his voice, deferential, yet with a faint undercurrent of honey-sweetness, irritated him inexplicably. With a scowl, he spurred forward, exchanged a brief greeting with Bud Jessup as he passed, and finally joined Kreeger, who was having considerable difficulty in keeping the herd together at that point. During the succeeding two hours or so, Buck forgot his irritation in the interest and excitement of the work. Strenuous as it was, he found a distinct pleasure in the discovery that two years' absence from the range had not lessened his ability to hold his own. His horse was well trained, and he thoroughly enjoyed the frequent sharp dashes after some refractory steer, who stubbornly opposed being driven. Before the last animal had passed through the fence-gap into the further pasture, he was drenched from head to foot with perspiration and his muscles ached from the unaccustomed labor, but all that was discounted by the satisfaction of doing his chosen work again, and doing it well. Then, in the lull which followed, his thoughts returned to Miss Thorne and he wondered whether there would be any chance for further conversation with her on the way back to the ranch-house? The question was quickly answered in a manner he did not in the least enjoy. After giving instructions about nailing up the fence, Tex Lynch joined the girl, who sat her horse at a little distance, and the two rode off together. For a moment or two Stratton's frowning glance followed them. Then of a sudden he realized that Slim McCabe's shrewd eyes were fixed curiously on him, and the discovery brought him abruptly to his senses. For a space he had forgotten what his position was at the Shoe-Bar. He must keep a better guard over himself, or he would certainly arouse suspicion. Averting his eyes, but still continuing to frown a little as if lack of tobacco was responsible for his annoyance, he searched through his pockets. "Got the makin's?" he asked McCabe. "Darned if I haven't left mine in the bunk-house." Slim readily produced a sack, and when Buck had rolled a cigarette, he returned it with a jesting remark, and swung himself rather stiffly out of his saddle. "Haven't any hammer, but I can help tighten wires," he commented. He had intended joining Bud Jessup and trying while helping him to get a chance to discuss some of the things he had learned from Bemis. But somehow he found himself working beside McCabe, and when the fence had been put up again and they started home, it was Slim who rode beside him, chatting volubly and amusingly, but sticking like a leach. It "gave one to think," Stratton decided grimly, remembering the expressive French phrase he had heard so often overseas. He could not quite make up his mind whether the action was deliberate or the result of accident, but after supper he had no doubt whatever.
