The Yak was tenacious of life. He was still holding his own. For the first time Gale really looked at the Indian to study him. He had a large head nobly cast, and a face that resembled a shrunken mask. It seemed chiseled in the dark-red, volcanic lava of his Sooner wilderness. The Indian's eyes were always black and mystic, but this Yak's encompassed all the tragic desolation of the desert. They were fixed on Gale, moved only when he moved. The Indian was short and broad, and his body showed unusual muscular development, although he seemed greatly emaciated from starvation or illness.

Gale resumed his homeward journey. When he got through the pass he faced a great depression, as rough as if millions of gigantic spikes had been driven by the hammer of Thorn into a seamed and cracked floor. This was Altar Valley. It was a chaos of array's, canyons, rocks, and ridges all mantled with cactus, and at its eastern end it claimed the dry bed of Forlorn River and water when there was any. With a wounded, helpless man across the saddle, this stretch of thorny and contorted desert was practically impassable. Yet Gale headed into it unflinchingly. He would carry the Yaqui as far as possible, or until death made the burden no longer a duty. Blanco Sol plodded on over the dragging sand, up and down the steep, loose banks of washes, out on the rocks, and through the rows of white-toothed choyas.

The sun sloped westward, bending fiercer heat in vengeful, parting reluctance. The wind slackened. The dust settled. And the bold, forbidding front of No Name Mountains changed to red and gold. Gale held grimly by the side of the tireless, implacable horse, holding the Yaqui on the saddle, taking the brunt of the merciless thorns. In the end it became heartrending toil. His heavy chaps dragged him down; but he dared not go on without them, for, thick and stiff as they were, the terrible, steel-bayoneted spikes of the choyas pierced through to sting his legs.

To the last mile Gale held to Blanco Sol's gait and kept ever-watchful gaze ahead on the trail. Then, with the low, flat houses of Forlorn River shining red in the sunset, Gale flagged and rapidly weakened. The Yaqui slipped out of the saddle and dropped limp in the sand. Gale could not mount his horse. He clutched Sol's long tail and twisted his hand in it and staggered on.

Blanco Sol whistled a piercing blast. He scented cool water and sweet alfalfa hay. Twinkling lights ahead meant rest. The melancholy desert twilight rapidly succeeded the sunset. It accentuated the forlorn loneliness of the gray, winding river of sand and its grayer shores. Night shadows trooped down from the black and looming mountains.

"A crippled Yaqui! Why the hell did you saddle yourself with him?" roared Belding, as he laid Gale upon the bed.

Belding had grown hard these late, violent weeks.

"Because I chose," whispered Gale, in reply. "Go after him--he dropped in the trail--across the river--near the first big saguaro."
