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.
