Scott did find something, however, in a sort of a nest fashioned among the bales near the middle of the wagon. What would have escaped an eye less trained to look for trifles attracted his at once. It was a dingy metal tag. Scott picked it up. It bore the name of a Medicine Bend saloon and the heads of three horses, from the design of which the saloon itself took a widely known and ill name. He laid his hand on the blanket from which he had picked the tag. The wool was still warm. Scott only smiled to himself. Both ends of the little canyon were guarded. From where he was searching the scout peered carefully out at the canyon walls. There were hiding-places, but they were hardly large enough to conceal a man. It was somewhere in the rocks close at hand that the fugitives had found a temporary refuge; but they could not now escape--nor could they be far from the wagon. Without losing sight of the surroundings, Scott, disclosing nothing of his discovery to the trader, announced that he was satisfied and that the men he wanted did not appear to be there. He added, however, that if the Frenchman had no objection his party would pitch camp close by and ride with him in the morning. The Frenchman maintained his courtesy by inviting the party to take supper with him, and Scott, agreeing to return, rode away with Hawk and the three troopers. They had not ridden far, when Bob dismounted the party and leaving the horses with one trooper set two as pickets and posted himself in hiding on one side the canyon, with Hawk on the other, to watch the camp. What he saw or whether his patience was in any degree rewarded no one could have told from his inscrutable face as he walked into the camp at dusk and sat down with the trader to supper. The moon was just rising and down at the creek, a little way from where Scott sat, some belated teamsters were washing their hands and faces and preparing their own supper. Scott ate slowly and with his back to the fire kept his eye on the group of men down at the creek. When he had finished, he walked down to the stream himself. A large man in the group fitted, in his hat and dress, Bucks's exact description. Scott had already spotted him an hour before, and stepped up to him now to arrest young John Rebstock. He laid his hand on the man's shoulder and the man turned. But to Scott's surprise he was not the man wanted at all. He wore Rebstock's clothes and fitted Rebstock's description, but he was not Rebstock. The scout understood instantly how he had been tricked, but gave no sign. Within the preceding thirty minutes the real Rebstock, whom Scott had already marked from his hiding-place in the canyon, had traded clothes with this man and, no doubt, made good his escape. If Bob was chagrined, he made no sign. "You must have made a good trade," he said, smiling at the teamster. "These clothes are a little big, but you will grow to them. How much boot did you get?"
