But these were things that King did not know. He only wondered about the man McCartney, in whom he found—though he could not have told why—the embodiment of a new and sinister antagonism. He could not help feeling that somehow powers over which he had no control were dealing the cards, and he had to play the game.

Had it not been for the fact that another—

His mind went back to the laughing eyes of the girl that had spoken to him from the cover of the bushes beside the trail.

Overhead the night-hawks whistled and swooped down with whirring wings above the tree-tops. The damp scent of low mist-filled hollows came to him on the motionless air, mingled with the cool fresh fragrance of the spruce. Little waves of warm air rose from the trail that had lain all day under a burning sky. The occasional call of a distant coyote whined across the plains, and returned in numberless echoes till it broke and died into silence.

Suddenly Sal stopped in the trail and stood looking back, her head up, her ears pricked forward, her tail brushing from side to side. King reined his horse in to a walk and listened. He could hear the rhythmic beat of hoofs on the trail some distance behind him. From the sound they made he knew the rider was coming fast. Curiosity overcame him, and he turned about and waited at a point in the trail from which he could look from cover across a deep hollow to where the trail was visible winding along near the base of the hill. He had been waiting only a few moments when the horse and rider came into view. The light had almost gone by now, but there was still enough left of the long northern summer twilight to make it possible for him to follow the dimly-outlined figures of horse and rider until they suddenly vanished where the trail ran hidden through a stretch of evergreens. When they emerged they were only a few yards away and in full sight. The rider was none other than the girl whose image he had kept before him in the failing twilight.

His first impulse was to turn his horse's head across the trail—he could not believe that the girl he had seen that afternoon was actually in control of the animal she rode. But not more than a dozen paces away the horse planted his feet before him suddenly, stopped with a jerk, and rose on his hind legs. Then with front feet still in the air he pivoted round and bolted away in the opposite direction. King was amazed to see the girl keep her seat, but his amazement increased when, just before reaching the turn, the horse stopped suddenly as he had done before, and wheeling about came up the trail towards him again at the same wild pace. King stood aside this time and caught a glimpse of the girl's face as she shot past him. The expression he saw there was enough to dispel any fears that he might have entertained for her safety. A few yards down the trail the horse turned again, and he saw the girl strike him across the nose with her quirt.

Then for fully ten minutes he watched a battle royal between a slender girl and a horse whose spirit had never been broken. He had seen men breaking horses to the saddle, and he had thrilled to the excitement of it. But this fight was different. The girl who held her seat in the battle that was being fought out before him did her work fearlessly, firmly, and without speaking a word, and King took off his hat and sat watching in silence.

Back and forth they went on the trail, the horse leaping and rearing at the turns, the girl wearing him down gradually with sharp strokes of her quirt across the nose. The horse shook his head at every stroke and came back after each turn with as much apparent determination as ever. The girl kept her place without a smile, her eyes steadily before her, intent on every move.

The end came suddenly. A quick stroke caught the animal just as his front feet were about to leave the ground, and he stood quivering in every limb, champing his bit and shaking his head in an effort to slacken the bridle rein that the girl held firmly in her hand. Then as he stood, trembling and subdued, the girl spoke for the first time, and turning him slowly round brought him down the trail at a walk.

King wanted to cry out in admiration of the superb manner in which the girl had conducted herself in the struggle, but when she came to where he stood she brought her horse to a standstill and turned to him with a smile—and King was dumb.
