Having located the valley, he slipped away, mounted his horse and rode back the way he had come, looking for a good place to pitch his camp. Five miles from the valley he found it--a cave-like recess under the towering wall of a butte, half way up the wooded slope which lay at the foot of the wall. From it he could command all approaches for several hundred yards, while his tarpaulin would be screened by bowlders and trees. It was high enough for purposes of observation, but not so high that the smoke from his fire would have density enough when it reached the top of the butte to be seen for any distance. A spring close by formed pools in the hollows of the rocks below him. The great buttes lying to the east of the fire would screen its light from any wandering member of Quigley's outfit. "This is it," he grunted. "We'll locate here tomorrow." The following day, having put his new camp to rights, he rode up the western slope of the great plateau which hemmed in Quigley's ranch, picketed his horse in a clearing, and after a cautious reconnaissance on foot he reached the edge of the cliffs, and the valley lay before him. Cattle grazed near a little lake, but at that distance he could not read the brands. He first had to find out if any of the outfit ever rode along the top of the cliffs, and he struck straight back to cross any such trails. By evening he had covered the western side of the ranch without finding a hoof-print, or a way up the sheer walls where a horseman could reach the top. There were several places where a cool-headed man could climb up, and at one of these Johnny found several burned matches. The next day was spent on the plateau north of the ranch, and the third and fourth days found him examining the eastern side; and it was here that he found signs of riders. There were three blind canyons on this side, and the middle one had a good trail running up its northern wall, and it appeared to be used frequently. At the top it divided, one branch running north and the other south. It was the only place on that side of the valley where a horseman could get out. Now that he had become familiar with his surroundings he began his real work. If Quigley had rustled, the operations could be divided into two classes: past operations, now finished; or present operations which were to continue. It was possible that enough cattle had been stolen in the past so that the natural increase would satisfy a man of modest ambitions. In this case his danger would decrease as time passed and eventually he would have a well-stocked range and be above suspicion. If he were avaricious the rustling would continue, if only spasmodically, until he had made all the money he wanted or until his operations became known.
