Slowly the desert sun drew overhead and swept the scant shadows from the brush-walled enclosure. Waring slept. Finally the big buckskin became restless, circling his picket and lifting his head to peer over the brush. Long before Waring could have been aware of it, had he been awake, the horse saw a moving something on the southern horizon. Trained to the game by years of a.s.sociation with his master, Dex walked to where Waring lay and nosed his arm. The gunman rolled to his side and peered through the chaparral.

Far in the south a moving dot wavered in the sun. Waring swept the southern arc with his gla.s.ses. The moving dot was a Mexican, a horseman riding alone. He rode fast. Waring could see the rise and fall of a quirt. "Some one killing a horse to get somewhere," he muttered, and he saddled Dex and waited. The tiny figure drew nearer. Dex grew restless.

Waring quieted him with a word.

To the west of the chaparral lay the trail, paralleled at a distance of a half-mile by the railroad. The gla.s.ses discovered the lone horseman to be Ramon, of Sonora. The boy swayed in the saddle as the horse lunged on. Waring knew that something of grave import had sent the boy out into the noon desert. He was at first inclined to let him pa.s.s and then ride east toward the Sierra Madre. If the rurales were following, they would trail Dex to the water-hole. And if Ramon rode on north, some of them would trail the Mexican. This would split up the band--decrease the odds by perhaps one half.

But the idea faded from Waring's mind as he saw the boy fling past desperately. Waring swung to the saddle and rode out. Ramon's horse plunged to a stop, and stood trembling. The boy all but fell as he dismounted. Stumbling toward Waring, he held out both hands.

"Senor, the rurales!" he gasped.

"How far behind?"

"The railroad! They are ahead! They have shipped their horses to Magdalena, to Nogales!"

"How do you know that?"

"Pedro Salazar is dead. You were gone. They say it was you."

"So they shipped their horses ahead to cut me off, eh? You're a good boy, Ramon, but I don't know what in h.e.l.l to do with you. Your cayuse is played out. You made a good ride."

"Si, senor. I have not stopped once."

"You look it. You can't go back now. They would shoot you."

"I will ride with the senor."

Waring shook his head.

Ramon's eyes grew desperate. "Senor," he pleaded, "take me with you! I cannot go back. I will be your man--follow you, even into the Great Beyond. You will not lose the way."

And as Ramon spoke he touched the little crucifix on his breast.

"Where did you find _that?_" asked Waring.

"In the Placeta Burro; near the house of Pedro Salazar."

Waring nodded. "Has your horse had water?"

"No, senor. I did not stop."

"Take him back to the water-hole. Or, here! Crawl in there and rest up.

You are all in. I'll take care of the cayuse."

When Waring returned to the chaparral, Ramon was asleep, flat on his back, his arms outspread and his mouth open. Waring touched him with his boot. Ramon muttered. Waring stooped and pulled him up.

Within the hour five rurales disembarked from a box-car and crossed to the water-hole, where one of them dismounted and searched for tracks.

Alert for the appearance of the gringo, they rode slowly toward the chaparral. The enclosure was empty. After riding a wide circle round the brush, they turned and followed the tracks toward the eastern hills, rein-chains jingling and their silver-trimmed buckskin jackets shimmering in the sun.

"I will ride back," said Ramon. "My horse is too weak to follow. The senor rides slowly that I may keep up with him."

Waring turned in the saddle. Ahead lay the shadowy foothills of the mother range, vague ma.s.ses in the starlight. Some thirty miles behind was the railroad and the trail north. There was no chance of picking up a fresh horse. The country was uninhabited. Alone, the gunman would have ridden swiftly to the hill country, where his trail would have been lost in the rocky ground of the ranges and where he would have had the advantage of an un.o.bstructed outlook from the high trails.

Ramon had said the rurales had entrained; were ahead of him to intercept him. But Waring, wise in his craft, knew that the man-hunters would search for tracks at every water-hole on the long northern trail. And if they found his tracks they would follow him to the hills. They were as keen on the trail as Yaquis and as relentless as wolves. Their horses, raw-hide tough, could stand a forced ride that would kill an ordinary horse. And Ramon's wiry little cayuse, though willing to go on until he dropped, could not last much longer.

But to leave Ramon to the rurales was not in Waring's mind. "We'll keep on, amigo," he said, "and in a few hours we'll know whether it's to be a ride or a fight."

"I shall pray," whispered Ramon.

"For a fresh horse, then."

"No, senor. That would be of no use. I shall pray that you may escape.

As for me--"

"We'll hit the glory trail together, muchacho. If you get b.u.mped off, it's your own funeral. You should have stayed in Sonora."

Ramon sighed. The senor was a strange man. Even now he hummed a song in the starlight. Was he, then, so unafraid of death that he could sing in the very shadow of its wings?

"You've got a hunch that the rurales are on our trail," said Waring, as they rode on.

"It is so, senor."

"How do you know?"

"I cannot say. But it is so. They have left the railroad and are following us."

Waring smiled in the dark. "Dex, here, has been trying to tell me that for an hour."

"And still the senor does not hasten!"

"I am giving your cayuse a chance to make the grade. We'll ride an hour longer."

Ramon bowed his head. The horses plodded on, working up the first gentle slope of the foothills. The brush loomed heavier. A hill star faded on the edge of the higher range. Ramon's lips moved and he crossed himself.

Waring hummed a song. He was not unhappy. The tang of life was his again. Again he followed a trail down which the light feet of Romance ran swiftly. The past, with its red flare of life, its keen memories and dulled regrets, was swept away by the promise of dawn and the unknown.

"A clean break and a hard fight," he murmured, as he reined up to rest his horse. Turning, he could distinguish Ramon, who fingered the crucifix at his throat. Waring's face grew grim. He felt suddenly accountable for the boy's life.

The half-moon glowed against the edge of the world. About to ride on again, Waring saw a tiny group of hors.e.m.e.n silhouetted against the half-disk of burning silver. He spoke to his horse. Slowly they climbed the ridge, dropped down the eastern slope, and climbed again.

In a shallow valley, Waring reined up, unsaddled Dex, and turned him loose. Ramon questioned this. "Turn your horse loose," said Waring.

"They'll keep together and find water."

Ramon shook his head, but did as he was told. Wearily he followed Waring as he climbed back to a rocky depression on the crest. Without a word Waring stretched behind a rock and was soon asleep. Ramon wondered at the other's indifference to danger, but fatigue finally overcame him and he slept.

Just before dawn Ramon awakened and touched

Waring. "They are coming!" he whispered.
