Off to the south lay the same bold, barren, desolate-looking expanse of rolling prairie. Blunt could not suppress a shudder as he thought of the terrible risk the boy had run in his mad break for the settlements beyond the Platte. Of course he could go nowhere else. North, east, and west, all was Indian land, and no lone white man could live there. Of course he was making for the cattle ranges and settlements in Nebraska. Such at least were the lieutenant's theories. He had spent only one year on the frontier, but had been there long enough to know that among the cowboys, ranchmen, and especially among the "riff-raff" ever hanging about the small towns and settlements, a deserter from the army was apt to be welcomed and protected, if he had money, arms, or a good horse. Once plundered of all he possessed, the luckless fellow might then be turned over to the nearest post and the authorized reward of thirty dollars claimed for his apprehension; but if well armed and sober, the deserter had little trouble in making his way through the toughest mining camps and settlements. CHAPTER V. TRAILING THE TRAITOR. Fred Waller knew all the Valley of the North Platte as well as he did the trails around Sanders and Red buttes, and if he could succeed in eluding the Indian war parties, he would have no difficulty in fording the river, or swimming if necessary; and, with the start he must have had, his light weight, and powerful horse, it would be next to impossible to catch him, even if they could follow his trail. Besides, were they not ordered to remain at the Niobrara until Charlton's return? The more Mr. Blunt thought of the matter the more worried and perplexed he became. Anywhere else he might have sent a sergeant with a couple of men in pursuit, but here it would be exposing them to almost certain death. It was some minutes before Sergeant Dawson came in answer to the summons. Blunt could see the troopers gathered about the first sergeant, excitedly discussing the affair and bemoaning their individual losses. Graham was noting the amounts on a slip of paper, and his fine face was pale with distress. "Is that all now, men?" he asked as he completed the list, then sharply turned away, and once more approached his young commander.
