Then the gray King began to run as if before he had been loping. He was beautiful in action. This was play—a game—a race—plainly dominated by the spirit of the girl. Lucy’s hair was a bright stream of gold in the wind. She rode bareback. It seemed that she was hunched low over Buckles with her knees high on his back—scarcely astride him at all. Yet her motion was one with the horse. Again that wild, gay scream pealed out—call or laugh or challenge. Sage King, with a fleetness that made the eyes of Bostil and his riders glisten, took the lead, and then sheered off to slow down, while Buckles thundered past. Lucy was pulling him hard, and had him plunging to a halt, when the rider Holley ran out to grasp his bridle. Buckles was snorting and his ears were laid back. He pounded the ground and scattered the pebbles.

“No use, Lucy,” said Bostil. “You can’t beat the King at your own game, even with a runnin’ start.”

Lucy Bostil’s eyes were blue, as keen as her father’s, and now they flashed like his. She had a hand twisted in the horse’s long mane, and as, lithe and supple, she slipped a knee across his broad back she shook a little gantleted fist at Bostil’s gray racer.

“Sage King, I hate you!” she called, as if the horse were human. “And I’ll beat you some day!”

Bostil swore by the gods his Sage King was the swiftest horse in all that wild upland country of wonderful horses. He swore the great gray could look back over his shoulder and run away from any broken horse known to the riders.

Bostil himself was half horse, and the half of him that was human he divided between love of his fleet racers and his daughter Lucy. He had seen years of hard riding on that wild Utah border where, in those days, a horse meant all the world to a man. A lucky strike of grassy upland and good water south of the Rio Colorado made him rich in all that he cared to own. The Indians, yet unspoiled by white men, were friendly. Bostil built a boat at the Indian crossing of the Colorado and the place became known as Bostil’s Ford. From time to time his personality and his reputation and his need brought horse-hunters, riders, sheep-herders, and men of pioneer spirit, as well as wandering desert travelers, to the Ford, and the lonely, isolated hamlet slowly grew. North of the river it was more than two hundred miles to the nearest little settlement, with only a few lonely ranches on the road; to the west were several villages, equally distant, but cut off for two months at a time by the raging Colorado, flooded by melting snow up in the mountains. Eastward from the Ford stretched a ghastly, broken, unknown desert of canyons. Southward rolled the beautiful uplands, with valleys of sage and grass, and plateaus of pine and cedar, until this rich rolling gray and green range broke sharply on a purple horizon line of upflung rocky ramparts and walls and monuments, wild, dim, and mysterious.

Bostil’s cattle and horses were numberless, and many as were his riders, he always could use more. But most riders did not abide long with Bostil, first because some of them were of a wandering breed, wild-horse hunters themselves; and secondly, Bostil had two great faults: he seldom paid a rider in money, and he never permitted one to own a fleet horse. He wanted to own all the fast horses himself. And in those days every rider, especially a wild-horse hunter, loved his steed as part of himself. If there was a difference between Bostil and any rider of the sage, it was that, as he had more horses, so he had more love.

Whenever Bostil could not get possession of a horse he coveted, either by purchase or trade, he invariably acquired a grievance toward the owner. This happened often, for riders were loath to part with their favorites. And he had made more than one enemy by his persistent nagging.
