Before Gale stretched a line of moving horses, white against dark shadows. He could not see the head of that column; he scarcely heard a soft hoofbeat. A single star shone out of a rift in thin clouds. There was no wind. The air was cold. The dark space of desert seemed to yawn. To the left across the river flickered a few campfires. The chill night, silent and mystical, seemed to close in upon Gale; and he faced the wide, quivering, black level with keen eyes and grim intent, and an awakening of that wild rapture which came like a spell to him in the open desert.
Blanco Sol showed no inclination to bend his head to the alfalfa which swished softly about his legs. Gale felt the horse's sensitive, almost human alertness. Sol knew as well as his master the nature of that flight.
At the far corner of the field Yaqui halted, and slowly the line of white horses merged into a compact mass. There was a trail here leading down to the river. the campfires were so close that the bright blazes could be seen in movement, and dark forms crossed in front of them. Yaqui slipped out of his saddle. He ran his hand over Diablo's nose and spoke low, and repeated this action for each of the other horses. Gale had long ceased to question the strange Indian's behavior. There was no explaining or understanding many of his manoeuvers. But the results of them were always thought-provoking. Gale had never seen horse stand so silently as in this instance; no stamp--no champ of bit--no toss of head--no shake of saddle or pack--no heave or snort! It seemed they had become imbued with the spirit of the Indian.
Yaqui moved away into the shadows as noiselessly as if he were one of them. The darkness swallowed him. He had taken a parallel with the trail. Gale wondered if Yaqui meant to try to lead his string of horses by the rebel sentinels. Ladd had his head bent low, his ear toward the trail. Jim's long neck had the arch of a listening deer. Gale listened, too, and as the slow, silent moments went by his faculty of hearing grew more acute from strain. He heard Blanco Sol breathe; he heard the pound of his own heart; he heard the silken rustle of the alfalfa; he heard a faint, far-off sound of voice, like a lost echo. Then his ear seemed to register a movement of air, a disturbance so soft as to be nameless. Then followed long, silent moments.
Yaqui appeared as he had vanished. He might have been part of the shadows. But he was there. He started off down the trail leading Diablo. Again the white line stretched slowly out. Gale fell in behind. A bench of ground, covered with sparse greasewood, sloped gently down to the deep, wide arroyo of Forlorn River. Blanco Sol shied a few feet out of the trail. Peering low with keen eyes, Gale made out three objects--a white sombrero, a blanket, and a Mexican lying face down. The Yaqui had stolen upon this sentinel like a silent wind of death. Just then a desert coyote wailed, and the wild cry fitted the darkness and the Yaqui's deed.
Once under the dark lee of the river bank Yaqui caused another halt, and he disappeared as before. It seemed to Gale that the Indian started to cross the pale level sandbed of the river, where stones stood out gray, and the darker line of opposite shore was visible. But he vanished, and it was impossible to tell whether he went one way or another. Moments passed. The horses held heads up, looked toward the glimmering campfires and listened. Gale thrilled with the meaning of it all--the night--the silence --the flight--and the wonderful Indian stealing with the slow inevitableness of doom upon another sentinel. An hour passed and Gale seemed to have become deadened to all sense of hearing. There were no more sounds in the world. The desert was as silent as it was black. Yet again came that strange change in the tensity of Gale's ear-strain, a check, a break, a vibration--and this time the sound did not go nameless. It might have been moan of wind or wail of far-distant wolf, but Gale imagined it was the strangling death-cry of another guard, or that strange, involuntary utterance of the Yaqui. Blanco Sol trembled in all his great frame, and then Gale was certain the sound was not imagination.
That certainty, once for all, fixed in Gale's mind the mood of his flight. The Yaqui dominated the horses and the rangers. Thorne and Mercedes were as persons under a spell. The Indian's strange silence, the feeling of mystery and power he seemed to create, all that was incomprehensible about him were emphasized in the light of his slow, sure, and ruthless action. If he dominated the others, surely he did more for Gale--colored his thoughts--presage the wild and terrible future of that flight. If Rojas embodied all the hatred and passion of the peon--scourged slave for a thousand years--then Yaqui embodied all the darkness, the cruelty, the white, sun-heated blood, the ferocity, the tragedy of the desert.
Suddenly the Indian stalked out of the gloom. He mounted Diablo and headed across the river. Once more the line of moving white shadows stretched out. The soft sand gave forth no sound at all. The glimmering campfires sank behind the western bank. Yaqui led the way into the willows, and there was faint swishing of leaves; then into the mesquite, and there was faint rustling of branches. The glimmering lights appeared again, and grotesque forms of saguaros loomed darkly. Gale peered sharply along the trail, and, presently, on the pale sand under a cactus, there lay a blanketed form, prone, outstretched, a carbine clutched in one hand, a cigarette, still burning, in the other.
