Above the mesa towered the snow peaks of the Crazy Kill Range. The snowbanks were not so close as they had been that morning, but seen through the high, thin air they seemed to be brooding no more than a short canter above the tableland. To the south, seen through a forest of trees and leaves much lighter green than the spruce, lay the desert, flat, eroded, purple in the evening light. The meadow was bordered on the lower side by an aspen grove. When the wind came up out of the canyon, the aspens seemed to shudder. A cross made of aspen wood had once been lifted on Calvary, so the preachers and the circuit rider said; possibly the aspens remembered. They quaked and their round leaves rattled and rustled like a million tiny cymbals. Below the aspen belt lay the scrub oaks, stunted trees with twigs as tough and hard as iron. The chestnut stallion felt safer here on the edge of the wild, high country. A short run would take his band into the scrub oaks where no rider could follow without dismounting. The sun dipped downward and hung on the blue rim of the western horizon. It looked like a huge ball of red fire. Slowly it settled from sight. Then shafts of red and gold light radiated upward, filling the sky and the air with a bloody haze. The wind died down and silence settled over the aspen grove. For a short space the world was aflame, then the sunset cooled and steel-blue dusk crept up out of the big canyon. The round moon, which had been dimmed to faint paleness by the sunset, flooded the mesa with soft light. The chestnut moved close to Lady Ebony. He nickered low. She tossed her head, and they were off on a wild gallop around the meadow. They ran through the moonlight, disregarding rocks and gopher holes, leaping over sage clumps and patches of buckbrush, their manes and tails billowing in the wind, their rushing bodies surging with power. They circled the meadow twice. Lady Ebony easily keeping ahead of the big stallion. After the second round, the black mare swerved and raced to a high, jutting point. Here she halted and the chestnut charged up beside her. He pawed and shook his head, then reared on his hind legs and his powerful forefeet curved under him. When his forefeet settled to the ground, Lady Ebony moved closer to him, her shoulder pressing against his muscled chest. The chestnut nickered proudly. From an aspen stand below the feeding mares leaped five shadowy gray forms. They ran with long leaps, their black muzzles lifting and falling with an even, graceful flow of motion. Red tongues lolled over white fangs and yellow eyes flamed in the moonlight. From shaggy chests came eager yelps. The chestnut blasted a shrill warning to the mares, but the wolves did not swerve to attack the colts. They raced across the mesa, running for the pure joy of giving play to their stringy muscles.
