assumed proportions that dwarfed those of its first ten miles. Venters rode on and on, not losing in the interest of his wide surroundings any of his caution or keen search for tracks or sight of living thing. If there ever had been a trail here, he could not find it. He rode through sage and clumps of pinon trees and grassy plots where long-petaled purple lilies bloomed. He rode through a dark constriction of the pass no wider than the lane in the grove at Cottonwoods. And he came out into a great amphitheater into which jutted huge towering corners of a confluence of intersecting canyons.
Venters sat his horse, and, with a rider's eye, studied this wild cross-cut of huge stone gullies. Then he went on, guided by the course of running water. If it had not been for the main stream of water flowing north he would never have been able to tell which of those many openings was a continuation of the pass. In crossing this amphitheater he went by the mouths of five canyons, fording little streams that flowed into the larger one. Gaining the outlet which he took to be the pass, he rode on again under over hanging walls. One side was dark in shade, the other light in sun. This narrow passageway turned and twisted and opened into a valley that amazed Venters.
Here again was a sweep of purple sage, richer than upon the higher levels. The valley was miles long, several wide, and inclosed by unscalable walls. But it was the background of this valley that so forcibly struck him. Across the sage-flat rose a strange up-flinging of yellow rocks. He could not tell which were close and which were distant. Scrawled mounds of stone, like mountain waves, seemed to roll up to steep bare slopes and towers.
In this plain of sage Venters flushed birds and rabbits, and when he had proceeded about a mile he caught sight of the bobbing white tails of a herd of running antelope. He rode along the edge of the stream which wound toward the western end of the slowly looming mounds of stone. The high slope retreated out of sight behind the nearer protection. To Venters the valley appeared to have been filled in by a mountain of melted stone that had hardened in strange shapes of rounded outline. He followed the stream till he lost it in a deep cut. Therefore Venters quit the dark slit which baffled further search in that direction, and rode out along the curved edge of stone where it met the sage. It was not long before he came to a low place, and here Wrangle readily climbed up.
All about him was ridgy roll of wind-smoothed, rain-washed rock. Not a tuft of grass or a bunch of sage colored the dull rust-yellow. He saw where, to the right, this uneven flow of stone ended in a blunt wall. Leftward, from the hollow that lay at his feet, mounted a gradual slow-swelling slope to a great height topped by leaning, cracked, and ruined crags. Not for some time did he grasp the wonder of that acclivity. It was no less than a mountain-side, glistening in the sun like polished granite, with cedar-trees springing as if by magic out of the denuded surface. Winds had swept it clear of weathered shale, and rains had washed it free of dust. Far up the curved slope its beautiful lines broke to meet the vertical rim-wall, to lose its grace in a different order and color of rock, a stained yellow cliff of cracks and caves and seamed crags. And straight before Venters was a scene less striking but more significant to his keen survey. For beyond a mile of the bare, hummocky rock began the valley of sage, and the mouths of canyons, one of which surely was another gateway into the pass.
He got off his horse, and, giving the bridle to Ring to hold, he commenced a search for the cleft where the stream ran. He was not successful and concluded the water dropped into an underground passage. Then he returned to where he had left Wrangle, and led him down off the stone to the sage. It was a short ride to the opening canyons. There was no reason for a choice of which one to enter. The one he rode into was a clear, sharp shaft in yellow stone a thousand feet deep, with wonderful wind-worn caves low down and high above buttressed and turreted ramparts. Farther on Venters came into a region where deep indentations marked the line of canyon walls. These were huge, cove-like blind pockets extending back to a sharp corner with a dense growth of underbrush and trees.
Venters penetrated into one of these offshoots, and, as he had hoped, he found abundant grass. He had to bend the oak saplings to get his horse through. Deciding to make this a hiding-place if he could find water, he worked back to the limit of the shelving walls. In a little cluster of silver spruces he found a spring. This inclosed nook seemed an ideal place to leave his horse and to camp at night, and from which to make stealthy trips on foot. The thick grass hid his trail; the dense growth of oaks in the opening would serve as a barrier to keep Wrangle in, if, indeed, the luxuriant browse would not suffice for that. So Venters, leaving Whitie with the horse, called Ring to his side, and, rifle in hand, worked his way out to the open. A careful photographing in mind of the formation of the bold outlines of rimrock assured him he would be able to return to his retreat even in the dark.
Bunches of scattered sage covered the center of the canyon, and among these Venters threaded his way with the step of an Indian. At intervals he put his hand on the dog and stopped to listen. There was a drowsy hum of insects, but no other sound disturbed the warm midday stillness. Venters saw ahead a turn, more abrupt than any yet. Warily he rounded this corner, once again to halt bewildered.
The canyon opened fan-shaped into a great oval of green and gray growths. It was the hub of an oblong wheel, and from it, at regular distances, like spokes, ran the outgoing canyons. Here a dull red color predominated over the fading yellow. The corners of wall bluntly rose, scarred and scrawled, to taper into towers and serrated peaks and pinnacled domes.
Venters pushed on more heedfully than ever. Toward the center of this circle the sage-brush grew smaller and farther apart He was about to sheer off to the right, where thickets and jumbles of fallen rock would afford him cover, when he ran right upon a broad cattle trail. Like a road it was, more than a trail, and the cattle tracks were fresh. What surprised him more, they were wet! He pondered over this feature. It had not rained. The only solution to this puzzle was that the cattle had been driven through water, and water deep enough to wet their legs.
Suddenly Ring growled low. Venters rose cautiously and looked over the sage. A band of straggling horsemen were riding across the oval. He sank down, startled and trembling. “Rustlers!” he muttered. Hurriedly he glanced about for a place to hide. Near at hand there was nothing but sage-brush. He dared not risk crossing the open patches to reach the rocks. Again he peeped over the sage. The rustlers—four—five—seven—eight in all, were approaching, but not directly in line with him. That was relief for a cold deadness which seemed to be creeping inward along his veins. He crouched down with bated breath and held the bristling dog.
He heard the click of iron-shod hoofs on stone, the coarse laughter of men, and then voices gradually dying away. Long moments passed. Then he rose. The rustlers were riding into a canyon. Their horses were tired, and they had several pack animals; evidently they had traveled far. Venters doubted that they were the rustlers who had driven the red herd. Olding's band had split. Venters watched these horsemen disappear under a bold canyon wall.
The rustlers had come from the northwest side of the oval. Venters kept a steady gaze in that direction, hoping, if there were more, to see from what canyon they rode. A quarter of an hour went by. Reward for his vigilance came when he descried three more mounted men, far over to the north. But out of what canyon they had ridden it was too late to tell. He watched the three ride across the oval and round the jutting red corner where the others had gone.
“Up that canyon!” exclaimed Venters. “Oldring's den! I've found it!”
A knotty point for Venters was the fact that the cattle tracks all pointed west. The broad trail came from the direction of the canyon into which the rustlers had ridden, and undoubtedly the cattle had been driven out of it across the oval. There were no tracks pointing the other way. It had been in his mind that Oldring had driven the red herd toward the rendezvous, and not from it. Where did that broad trail come down into the pass, and where did it lead? Venters knew he wasted time in pondering the question, but it held a fascination not easily dispelled. For many years Oldring's mysterious entrance and exit to Deception Pass had been all-absorbing topics to sage-riders.
All at once the dog put an end to Venters's pondering. Ring sniffed the air, turned slowly in his tracks with a whine, and then growled. Venters wheeled. Two horsemen were within a hundred yards, coming straight at him. One, lagging behind the other, was Oldring's Masked Rider.
