It did not take Slone long to decide to lead the horse and work up the canyon past the campers. He must get ahead of them, and once there he had no fear of them, either by night or day. He really had no hopes of getting by undiscovered, and all he wished for was to get far enough so that he could not be intercepted. The grazing horses would scent Wildfire or he would scent them.

For a wonder Wildfire allowed himself to be led as well as if he had been old, faithful Nagger. Slone could not keep close in to the wall for very long, on account of the cedars, but he managed to stay in the outer edge of shadow cast by the wall. Wildfire winded the horses, halted, threw up his head. But for some reason beyond Slone the horse did not snort or whistle. As he knew Wildfire he could have believed him intelligent enough and hateful enough to betray his master.

It was one of the other horses that whistled an alarm. This came at a point almost even with the camp-fire. Slone, holding Wildfire down, had no time to get into a stirrup, but leaped to the saddle and let the horse go. There were hoa.r.s.e yells and then streaks of fire and shots.

Slone heard the whizz of heavy bullets, and he feared for Wildfire. But the horse drew swiftly away into the darkness. Slone could not see whether the ground was smooth or broken, and he left that to Wildfire.

Luck favored them, and presently Slone pulled him in to a safe gait, and regretted only that he had not had a chance to take a shot at that camp.

Slone walked the horse for an hour, and then decided that he could well risk a halt for the night.

Before dawn he was up, warming his chilled body by violent movements, and forcing himself to eat.

The rim of the west wall changed from gray to pink. A mocking-bird burst into song. A coyote sneaked away from the light of day. Out in the open Slone found the trail made by Creech's mustangs and by the horse of Cordts's man. The latter could not be very far ahead. In less than an hour Slone came to a clump of cedars where this man had camped.

An hour behind him!

This canyon was open, with a level and narrow floor divided by a deep wash. Slone put Wildfire to a gallop. The narrow wash was no obstacle to Wildfire; he did not have to be urged or checked. It was not long before Slone saw a horseman a quarter of a mile ahead, and he was discovered almost at the same time. This fellow showed both surprise and fear. He ran his horse. But in comparison with Wildfire that horse seemed sluggish. Slone would have caught up with him very soon but for a change in the lay of the land. The canyon split up and all of its gorges and ravines and washes headed upon the pine-fringed plateau, now only a few miles distant. The gait of the horses had to be reduced to a trot, and then a walk. The man Slone was after left Creech's trail and took to a side cleft. Slone, convinced he would soon overhaul him, and then return to take up Creech's trail, kept on in pursuit. Then Slone was compelled to climb. Wildfire was so superior to the other's horse, and Slone was so keen at choosing ground and short cuts, that he would have been right upon him but for a split in the rock which suddenly yawned across his path. It was impa.s.sable. After a quick glance Slone abandoned the direct pursuit, and, turning along this gulch, he gained a point where the horse-thief would pa.s.s under the base of the rim-wall, and here Slone would have him within easy rifle shot.

And the man, intent on getting out of the canyon, rode into the trap, approaching to within a hundred yards of Slone, who suddenly showed himself on foot, rifle in hand. The deep gulch was a barrier to Slone's further progress, but his rifle dominated the situation.

"Hold on!" he called, warningly.

"Hold on yerself!" yelled the other, aghast, as he halted his horse. He gazed down and evidently was quick to take in the facts.

Slone had meant to kill this man without even a word, yet now when the moment had come a feeling almost of sickness clouded his resolve. But he leveled the rifle.

"I got it on you," he called.

"Reckon you hev. But see hyar--"

"I can hit you anywhere."

"Wal, I'll take yer word fer thet."

"All right. Now talk fast.... Are you one of Cordts's gang?"

"Sure."

"Why are you alone?"

"We split down hyar."

"Did you know I was on this trail?"

"Nope. I didn't sure, or you'd never ketched me, red hoss or no."

"Who were you trailin'?"

"Ole Creech an' the girl he kidnapped."

Slone felt the leap of his blood and the jerk it gave the rifle as his tense finger trembled on the trigger.

"Girl.... What girl?" he called, hoa.r.s.ely.

"Bostil's girl."

"Why did Cordts split on the trail?"

"He an' Hutch went round fer some more of the gang, an' to head off Joel Creech when he comes in with Bostil's hosses."

Slone was amazed to find how the horse thieves had calculated; yet, on second thought, the situation, once the Creeches had been recognized, appeared simple enough.

"What was your game?" he demanded.

"I was follerin' Creech jest to find out where he'd hole up with the girl."

"What's Cordts's game--AFTER he heads Joel Creech?"

"Then he's goin' fer the girl."

Slone scarcely needed to be told all this, but the deliberate words from the lips of one of Cordts's gang bore a raw, brutal proof of Lucy's peril. And yet Slone could not bring himself to kill this man in cold blood. He tried, but in vain.

"Have you got a gun?" called Slone, hoa.r.s.ely.

"Sure."

"Ride back the other way! ... If you don't lose me I'll kill you!"

The man stared. Slone saw the color return to his pale face. Then he turned his horse and rode back out of sight. Slone heard him rolling the stones down the long, rough slope; and when he felt sure the horse-thief had gotten a fair start he went back to mount Wildfire in pursuit.

This trailer of Lucy never got back to Lucy's trail--never got away.

But Slone, when that day's hard, deadly pursuit ended, found himself lost in the canyons. How bitterly he cursed both his weakness in not shooting the man at sight, and his strength in following him with implacable purpose! For to be fair, to give the horse-thief a chance for his life, Slone had lost Lucy's trail. The fact nearly distracted him. He spent a sleepless night of torture.

All next day, like a wild man, he rode and climbed and descended, spurred by one purpose, pursued by suspense and dread. That night he tied Wildfire near water and gra.s.s and fell into the sleep of exhaustion.

Morning came. But with it no hope. He had been desperate. And now he was in a frightful state. It seemed that days and days had pa.s.sed, and nights that were hideous with futile nightmares.

He rode down into a canyon with sloping walls, and broken, like all of these canyons under the great plateau. Every canyon resembled another.

The upland was one vast network. The world seemed a labyrinth of canyons among which he was hopelessly lost. What would--what had become of Lucy? Every thought in his whirling brain led back to that--and it was terrible.

Then--he was gazing transfixed down upon the familiar tracks left by Creech's mustangs. Days old, but still unfollowed!

CHAPTER XIX

That track led up the narrowing canyon to its head at the base of the plateau.

Slone, mindful of his horse, climbed on foot, halting at the zigzag turns to rest. A long, gradually ascending trail mounted the last slope, which when close at hand was not so precipitous as it appeared from below. Up there the wind, sucked out of the canyons, swooped and twisted hard.
