While Mackenzie was yet a hundred yards from Reid he saw him swing from the saddle and shelter himself behind his horse. Hall and his companion were standing off warily, a good pistol shot from Reid, distrustful of this sudden change in his tactics, apparently believing he had come to the place he had selected to make his defensive stand. A little while they stood waiting for him to fire, then separated, the stranger circling to come behind Mackenzie, Hall moving a little nearer to Reid, who kept his horse before him with the craft of an Indian. Hall stood a little while, as if waiting for Reid to fire, then rode forward, throwing a stream of lead as he came. Reid's horse reared, ran a few rods with head thrown wildly high, its master clinging to the bit, dragging over shrub and stone. Suddenly it collapsed forward on its knees, and stretched dead. Reid flung himself to the ground behind the protection of its carcass, Hall pausing in his assault to reload. The man who had ridden a wide and cautious circuit to get behind Mackenzie now dismounted and began firing across his saddle. Mackenzie turned, a pistol in each hand, indecisive a moment whether to return the fellow's fire or rush forward and join Reid behind the breastworks of his beast. The stranger was nearer Mackenzie by many rods than Hall, but still so far away that his shots went wide, whistling high over Mackenzie's head, or kicking dirt among the shrubs at either hand. Hall was charging down on Reid again, but with a wariness that held him off a distance of comparative safety. In the moment that he paused there, considering the best and quickest move to make to lessen Reid's peril, the thought shot to Mackenzie like a rending of confusing clouds that it was not so much Reid's peril as his own. These men had come to kill him; their sighting Reid on the way was only an incident. It was his fight, and not Reid's, for Reid was safe behind his horse, lying along its body close to the ground like a snake. This understanding of the situation cleared the air tremendously. Where he had seen in confusion, with a sense of mingling and turning but a moment before, Mackenzie now beheld things with the sharpness of self-interest, calculating his situation with a comprehensive appraisement of every yard that lay between him and his enemies. He was steady as a tree, light with a feeling of relief, of justification for his acts. It was as if putting off the thought that he was going into this fight for Earl Reid had taken bonds from his arms, leaving him free to breathe joyously and strike with the keenness of a man who has a wild glory in facing tremendous odds. All in a moment this clearing of brain and limb came to him, setting him up as if he had passed under an icy torrent and come out refreshed and clear-eyed into the sun. He bent low behind a shrub and rushed down the hillside toward the man who stood reloading his pistol, his hat-crown showing above the saddle.
