And like a scouting Indian Venters crawled through the sage of the oval valley, crossed trail after trail on the north side, and at last entered the canyon out of which headed the cattle trail, and into which he had watched the rustlers disappear.

If he had used caution before, now he strained every nerve to force himself to creeping stealth and to sensitiveness of ear. He crawled along so hidden that he could not use his eyes except to aid himself in the toilsome progress through the brakes and ruins of cliff-wall. Yet from time to time, as he rested, he saw the massive red walls growing higher and wilder, more looming and broken. He made note of the fact that he was turning and climbing. The sage and thickets of oak and brakes of alder gave place to pinyon pine growing out of rocky soil. Suddenly a low, dull murmur assailed his ears. At first he thought it was thunder, then the slipping of a weathered slope of rock. But it was incessant, and as he progressed it filled out deeper and from a murmur changed into a soft roar.

"Falling water," he said. "There's volume to that. I wonder if it's the stream I lost."

The roar bothered him, for he could hear nothing else. Likewise, however, no rustlers could hear him. Emboldened by this and sure that nothing but a bird could see him, he arose from his hands and knees to hurry on. An opening in the pinyons warned him that he was nearing the height of slope.

He gained it, and dropped low with a burst of astonishment.

Before him stretched a short canyon with rounded stone floor bare of grass or sage or tree, and with curved, shelving walls. A broad rippling stream flowed toward him, and at the back of the canyon waterfall burst from a wide rent in the cliff, and, bounding down in two green steps, spread into a long white sheet.

If Venters had not been indubitably certain that he had entered the right canyon his astonishment would not have been so great.

There had been no breaks in the walls, no side canyons entering this one where the rustlers' tracks and the cattle trail had guided him, and, therefore, he could not be wrong. But here the canyon ended, and presumably the trails also.

"That cattle trail headed out of here," Venters kept saying to himself. "It headed out. Now what I want to know is how on earth did cattle ever get in here?"

If he could be sure of anything it was of the careful scrutiny he had given that cattle track, every hoofmark of which headed straight west. He was now looking east at an immense round boxed corner of canyon down which tumbled a thin, white veil of water, scarcely twenty yards wide. Somehow, somewhere, his calculations had gone wrong. For the first time in years he found himself doubting his rider's skill in finding tracks, and his memory of what he had actually seen. In his anxiety to keep under cover he must have lost himself in this offshoot of Deception Pass, and thereby in some unaccountable manner, missed the canyon with the trails. There was nothing else for him to think. Rustlers could not fly, nor cattle jump down thousand-foot precipices. He was only proving what the sage-riders had long said of this labyrinthine system of deceitful canyons and valleys--trails led down into Deception Pass, but no rider had ever followed them.
