Wildfire worked away from this open valley, back to the south end, where the great monuments loomed, and still farther back, where they grew closer, till at length some of them were joined by weathered ridges to the walls of the surrounding plateau. For all that Slone could see, Wildfire was in perfect condition. But Nagger was not the horse he had been. Slone realized that in one way or another the pursuit was narrowing down to the end.

He found a water-hole at the head of a wash in a split in the walls, and here he let Nagger rest and graze one whole day--the first day for a long time that he had not kept the red stallion in sight. That day was marked by the good fortune of killing a rabbit, and while eating it his gloomy, fixed mind admitted that he was starving. He dreaded the next sunrise. But he could not hold it back. There, behind the dark monuments, standing sentinel-like, the sky lightened and reddened and burst into gold and pink, till out of the golden glare the sun rose glorious. And Slone, facing the league-long shadows of the monuments, rode out again into the silent, solemn day, on his hopeless quest.

For a change Wildfire had climbed high up a slope of talus, through a narrow pa.s.s, rounded over with drifting sand. And Slone gazed down into a huge amphitheater full of monuments, like all that strange country. A basin three miles across lay beneath him. Walls and weathered slants of rock and steep slopes of reddish-yellow sand inclosed this oval depression. The floor was white, and it seemed to move gently or radiate with heat-waves. Studying it, Slone made out that the motion was caused by wind in long bleached gra.s.s. He had crossed small areas of this gra.s.s in different parts of the region.

Wildfire's tracks led down into this basin, and presently Slone, by straining his eyes, made out the red spot that was the stallion.

"He's lookin' to quit the country," soliloquized Slone, as he surveyed the scene.

With keen, slow gaze Slone studied the lay of wall and slope, and when he had circled the huge depression he made sure that Wildfire could not get out except by the narrow pa.s.s through which he had gone in. Slone sat astride Nagger in the mouth of this pa.s.s--a wash a few yards wide, walled by broken, rough rock on one side and an insurmountable slope on the other.

"If this hole was only little, now," sighed Slone, as he gazed at the sweeping, shimmering oval floor, "I might have a chance. But down there--we couldn't get near him."

There was no water in that dry bowl. Slone reflected on the uselessness of keeping Wildfire down there, because Nagger could not go without water as long as Wildfire. For the first time Slone hesitated. It seemed merciless to Nagger to drive him down into this hot, windy hole.

The wind blew from the west, and it swooped up the slope, hot, with the odor of dry, dead gra.s.s.

But that hot wind stirred Slone with an idea, and suddenly he was tense, excited, glowing, yet grim and hard.

"Wildfire, I'll make you run with your namesake in that high gra.s.s,"

called Slone. The speech was full of bitter failure, of regret, of the hardness of a rider who could not give up the horse to freedom.

Slone meant to ride down there and fire the long gra.s.s. In that wind there would indeed be wildfire to race with the red stallion. It would perhaps mean his death; at least it would chase him out of that hole, where to follow him would be useless.

"I'd make you hump now to get away if I could get behind you," muttered Slone. He saw that if he could fire the gra.s.s on the other side the wind of flame would drive Wildfire straight toward him. The slopes and walls narrowed up to the pa.s.s, but high gra.s.s grew to within a few rods of where Slone stood. But it seemed impossible to get behind Wildfire.

"At night--then--I could get round him," said Slone, thinking hard and narrowing his gaze to scan the circle of wall and slope. "Why not? ...

No wind at night. That gra.s.s would burn slow till mornin'--till the wind came up--an' it's been west for days."

Suddenly Slone began to pound the patient Nagger and to cry out to him in wild exultance.

"Old horse, we've got him! ... We've got him! ... We'll put a rope on him before this time to-morrow!"

Slone yielded to his strange, wild joy, but it did not last long, soon succeeding to sober, keen thought. He rode down into the bowl a mile, making absolutely certain that Wildfire could not climb out on that side. The far end, beyond the monuments, was a sheer wall of rock. Then he crossed to the left side. Here the sandy slope was almost too steep for even him to go up. And there was gra.s.s that would burn. He returned to the pa.s.s a.s.sured that Wildfire had at last fallen into a trap the like Slone had never dreamed of. The great horse was doomed to run into living flame or the whirling noose of a la.s.so.

Then Slone reflected. Nagger had that very morning had his fill of good water--the first really satisfying drink for days. If he was rested that day, on the morrow he would be fit for the grueling work possibly in store for him. Slone unsaddled the horse and turned him loose, and with a snort he made down the gentle slope for the gra.s.s. Then Slone carried his saddle to a shady spot afforded by a slab of rock and a dwarf cedar, and here he composed himself to rest and watch and think and wait.

Wildfire was plainly in sight no more than two miles away. Gradually he was grazing along toward the monuments and the far end of the great basin. Slone believed, because the place was so large, that Wildfire thought there was a way out on the other side or over the slopes or through the walls. Never before had the far-sighted stallion made a mistake. Slone suddenly felt the keen, stabbing fear of an outlet somewhere. But it left him quickly. He had studied those slopes and walls. Wildfire could not get out, except by the pa.s.s he had entered, unless he could fly.

Slone lay in the shade, his head propped on his saddle, and while gazing down into the shimmering hollow he began to plan. He calculated that he must be able to carry fire swiftly across the far end of the basin, so that he would not be absent long from the mouth of the pa.s.s.

Fire was always a difficult matter, since he must depend only on flint and steel. He decided to wait till dark, build a fire with dead cedar sticks, and carry a bundle of them with burning ends. He felt a.s.sured that the wind caused by riding would keep them burning. After he had lighted the gra.s.s all he had to do was to hurry back to his station and there await developments.

The day pa.s.sed slowly, and it was hot. The heat-waves rose in dark, wavering lines and veils from the valley. The wind blew almost a gale.

Thin, curling sheets of sand blew up over the crests of the slopes, and the sound it made was a soft, silken rustling, very low. The sky was a steely blue above and copper close over the distant walls.

That afternoon, toward the close, Slone ate the last of the meat. At sunset the wind died away and the air cooled. There was a strip of red along the wall of rock and on the tips of the monuments, and it lingered there for long, a strange, bright crown. Nagger was not far away, but Wildfire had disappeared, probably behind one of the monuments.

When twilight fell Slone went down after Nagger and, returning with him, put on bridle and saddle. Then he began to search for suitable sticks of wood. Farther back in the pa.s.s he found stunted dead cedars, and from these secured enough for his purpose. He kindled a fire and burnt the ends of the sticks into red embers. Making a bundle of these, he put them under his arm, the dull, glowing ends backward, and then mounted his horse.

It was just about dark when he faced down into the valley. When he reached level ground he kept to the edge of the left slope and put Nagger to a good trot. The gra.s.s and brush were scant here, and the color of the sand was light, so he had no difficulty in traveling.

From time to time his horse went through gra.s.s, and its dry, crackling rustle, showing how it would burn, was music to Slone. Gradually the monuments began to loom up, bold and black against the blue sky, with stars seemingly hanging close over them. Slone had calculated that the basin was smaller than it really was, in both length and breadth. This worried him. Wildfire might see or hear or scent him, and make a break back to the pa.s.s and thus escape. Slone was glad when the huge, dark monuments were indistinguishable from the black, frowning wall. He had to go slower here, because of the darkness. But at last he reached the slow rise of jumbled rock that evidently marked the extent of weathering on that side. Here he turned to the right and rode out into the valley. The floor was level and thickly overgrown with long, dead gra.s.s and dead greasewood, as dry as tinder. It was easy to account for the dryness; neither snow nor rain had visited that valley for many months. Slone whipped one of the sticks in the wind and soon had the smoldering end red and showering sparks. Then he dropped the stick in the gra.s.s, with curious intent and a strange feeling of regret.

Instantly the gra.s.s blazed with a little sputtering roar. Nagger snorted. "Wildfire!" exclaimed Slone. That word was a favorite one with riders, and now Slone used it both to call out his menace to the stallion and to express his feeling for that blaze, already running wild.

Without looking back Slone rode across the valley, dropping a glowing stick every quarter of a mile. When he reached the other side there were a dozen fires behind him, burning slowly, with white smoke rising lazily. Then he loped Nagger along the side back to the sandy ascent, and on up to the mouth of the pa.s.s. There he searched for tracks.

Wildfire had not gone out, and Slone experienced relief and exultation.

He took up a position in the middle of the narrowest part of the pa.s.s, and there, with Nagger ready for anything, he once more composed himself to watch and wait.

Far across the darkness of the valley, low down, twelve lines of fire, widely separated, crept toward one another. They appeared thin and slow, with only an occasional leaping flame. And some of the black s.p.a.ces must have been monuments, blotting out the creeping snail-lines of red. Slone watched, strangely fascinated.

"What do you think of that?" he said, aloud, and he meant his query for Wildfire.

As he watched the lines perceptibly lengthened and brightened and pale shadows of smoke began to appear. Over at the left of the valley the two brightest fires, the first he had started, crept closer and closer together. They seemed long in covering distance. But not a breath of wind stirred, and besides they really might move swiftly, without looking so to Slone. When the two lines met a sudden and larger blaze rose.

"Ah!" said the rider, and then he watched the other lines creeping together. How slowly fire moved, he thought. The red stallion would have every chance to run between those lines, if he dared. But a wild horse feared nothing like fire. This one would not run the gantlet of flames. Nevertheless, Slone felt more and more relieved as the lines closed. The hours of the night dragged past until at length one long, continuous line of fire spread level across the valley, its bright, red line broken only where the monuments of stone were silhouetted against it.

The darkness of the valley changed. The light of the moon changed. The radiance of the stars changed. Either the line of fire was finding denser fuel to consume or it was growing appreciably closer, for the flames began to grow, to leap, and to flare.

Slone strained his ears for the thud of hoofs on sand.

The time seemed endless in its futility of results, but fleeting after it had pa.s.sed; and he could tell how the hours fled by the ever-recurring need to replenish the little fire he kept burning in the pa.s.s.

A broad belt of valley grew bright in the light, and behind it loomed the monuments, weird and dark, with columns of yellow and white smoke wreathing them.

Suddenly Slone's sensitive ear vibrated to a thrilling sound. He leaned down to place his ear to the sand. Rapid, rhythmic beat of hoofs made him leap to his feet, reaching for his la.s.so with right hand and a gun with his left.

Nagger lifted his head, sniffed the air, and snorted. Slone peered into the black belt of gloom that lay below him. It would be hard to see a horse there, unless he got high enough to be silhouetted against that line of fire now flaring to the sky. But he heard the beat of hoofs, swift, sharp, louder--louder. The night shadows were deceptive. That wonderful light confused him, made the place unreal. Was he dreaming?

Or had the long chase and his privations unhinged his mind? He reached for Nagger. No! The big black was real, alive, quivering, pounding the sand. He scented an enemy.

Once more Slone peered down into the void or what seemed a void. But it, too, had changed, lightened. The whole valley was brightening.

Great palls of curling smoke rose white and yellow, to turn back as the monuments met their crests, and then to roll upward, blotting out the stars. It was such a light as he had never seen, except in dreams. Pale moonlight and dimmed starlight and wan dawn all vague and strange and shadowy under the wild and vivid light of burning gra.s.s.

In the pale path before Slone, that fanlike slope of sand which opened down into the valley, appeared a swiftly moving black object, like a fleeting phantom. It was a phantom horse. Slone felt that his eyes, deceived by his mind, saw racing images. Many a wild chase he had lived in dreams on some far desert. But what was that beating in his ears--sharp, swift, even, rhythmic? Never had his ears played him false. Never had he heard things in his dreams. That running object was a horse and he was coming like the wind. Slone felt something grip his heart. All the time and endurance and pain and thirst and suspense and longing and hopelessness--the agony of the whole endless chase--closed tight on his heart in that instant.

The running horse halted just in the belt of light cast by the burning gra.s.s. There he stood sharply defined, clear as a cameo, not a hundred paces from Slone. It was Wildfire.

Slone uttered an involuntary cry. Thrill on thrill shot through him.

Delight and hope and fear and despair claimed him in swift, successive flashes. And then again the ruling pa.s.sion of a rider held him--the sheer glory of a grand and unattainable horse. For Slone gave up Wildfire in that splendid moment. How had he ever dared to believe he could capture that wild stallion? Slone looked and looked, filling his mind, regretting nothing, sure that the moment was reward for all he had endured.

The weird lights magnified Wildfire and showed him clearly. He seemed gigantic. He shone black against the fire. His head was high, his mane flying. Behind him the fire flared and the valley-wide column of smoke rolled majestically upward, and the great monuments seemed to retreat darkly and mysteriously as the flames advanced beyond them. It was a beautiful, unearthly spectacle, with its silence the strangest feature.

But suddenly Wildfire broke that silence with a whistle which to Slone's overstrained faculties seemed a blast as piercing as the splitting sound of lightning. And with the whistle Wildfire plunged up toward the pa.s.s. Slone yelled at the top of his lungs and fired his gun before he could terrorize the stallion and drive him back down the slope. Soon Wildfire became again a running black object, and then he disappeared.

The great line of fire had gotten beyond the monuments and now stretched unbroken across the valley from wall to slope. Wildfire could never pierce that line of flames. And now Slone saw, in the paling sky to the east, that dawn was at hand.
