Taking it all in all, it was the most perfect range he ever had seen. Rich in grass so heavy and thick as to make him wonder at it, naturally irrigated, blessed with natural reservoirs, surrounded by a perpendicular wall of rock which at some places attained a height of three hundred feet, the water courses lined with timber, its arroyos and draws heavily wooded, and with but three places, easily closed and guarded, where cattle could get out, it made the Tin Cup and the Bar-20, large as they were, look like jokes. Its outfit could laugh at rustlers, droughts, and blizzards, grow fat and lazy and have neither boundary disputes nor range wars to bother them. There were no brands of neighboring ranches to complicate the roundups and not a cow would be lost through straying or theft.

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.

Johnny early had discovered that Quigley's brand was QE and this increased his suspicions, for the E could not be explained. Logan's brand was childishly simple to change: The C could become an O, Q, G, or wagon-wheel; the L would make an E, Triangle, Square, or a 4.

Satisfied that the foundation of Quigley's brand had been the CL, Johnny had to discover if Logan's cattle still were being taken to swell the Quigley herds. Logan's inaction and his easy-going way of running his ranch jarred Johnny, for the foreman had confessed that for the last few years the natural increase, figured in the fall roundups, had not tallied with the number of calves branded each preceding spring. But Logan was not altogether to blame, because the Barrier had given him a false security and there was nothing to fear from other directions. It was the last spring roundup and its tally sheets which had stirred him; and a close study of his drive-herd records and the use of the factor of natural increase suddenly brought to his mind a startling suspicion. Even then he wavered, fearing that he was allowing an old and bitter grudge to sway him unduly; and before he had time to make any real investigations, Johnny had appeared and demanded a job.

Among Quigley's cattle the proportion of calves to cows was so small that Johnny could not fail to notice it. He was satisfied that the QE, so prominently displayed, originally had been CL, but when he caught sight of a crusty old steer near the mouth of the second canyon all doubts were removed. While the mark was an old one, the rebranding had been done carelessly. The segment which closed the original C had not been properly joined to the old brand, and there was a space between the ends of the two marks where they overlapped. A look at the ears made him smile grimly, for Logan's shallow V notch had become a rounded scallop; and there was no honest reason why Quigley should notch the ears of his cows when there was no chance of them getting mixed up with the cattle of any other ranch. The scallop had been made simply to cut out the telltale V notch.
