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.

The cavalcade of white horses passed within five hundred yards of campfires, around which dark forms moved in plain sight. Soft pads in sand, faint metallic tickings of steel on thorns, low, regular breathing of horses--these were all the sounds the fugitives made, and they could not have been heard at one-fifth the distance. The lights disappeared from time to time, grew dimmer, more flickering, and at last they vanished altogether. Belding's fleet and tireless steeds were out in front; the desert opened ahead wide, dark, vast. Rojas and his rebels were behind, eating, drinking, careless. The somber shadow lifted from Gale's heart. He held now an unquenchable faith in the Yaqui. Belding would be listening back there along the river. He would know of the escape. He would tell Nell, and then hide her safely. As Gale accepted a strange and fatalistic foreshadowing of toil, blood, and agony in this desert journey, so he believed in Mercedes's ultimate freedom and happiness, and his own return to the girl who had grown dearer than life.

A cold, gray dawn was fleeing before a rosy sun when Yaqui halted the march at Papago Well. The horses were taken to water, then led down the arroyo into the grass. Here packs were slipped, saddles removed. Mercedes was cold, lame, tired, but happy. It warmed Gale's blood to look at her. The shadow of fear still lay in her eyes, but it was passing. Hope and courage shone there, and affection for her ranger protectors and the Yaqui, and unutterable love for the cavalryman. Jim Lash remarked how cleverly they had fooled the rebels.

"Shore they'll be comin' along," replied Ladd.

They built a fire, cooked and ate. The Yaqui spoke only one word: "Sleep." Blankets were spread. Mercedes dropped into a deep slumber, her head on Thorne's shoulder. Excitement kept Throne awake. The two rangers dozed beside the fire. Gale shared the Yaqui's watch. The sun began to climb and the icy edge of dawn to wear away. Rabbits bobbed their cotton tails under the mesquite. Gale climbed a rocky wall above the arroyo bank, and there, with command over the miles of the back-trail, he watched.

It was a sweeping, rolling, wrinkled, and streaked range of desert that he saw, ruddy in the morning sunlight, with patches of cactus and mesquite rough-etched in shimmering gloom. No Name Mountains split the eastern sky, towering high, gloomy, grand, with purple veils upon their slopes. They were forty miles away and looked five. Gale thought of the girl who was there under their shadow.
