Then for the first time in his history Ben Blair lost self-control. Quick as thought he changed his course from the house to the direction from which the shot had come. The great veins of his throat swelled until it seemed he could scarcely breathe. Curses, horrible, blighting curses, combinations of malediction which had never even in thought entered his mind before, rolled from his lips. His brain seemed afire. But one idea possessed him--to lay hands upon this intruding being who had in cold blood done that fiendish deed in the barn, and now had shot his best friend on earth. The rage of primitive man who knew not steel or gunpowder was his; the ferocity of the great monkey, the aborigine's predecessor, whose means of offence were teeth and nails. Straight ahead the man rushed, seeming not to run, but fairly to bound, turned suddenly the angle at the corner of the machinery shed, stumbled over a snow-plough drawn up carelessly by one of the men, fell, regained his feet, and heard in his ears the thundering hoof-beats of a horse urged away at full speed. For a moment Ben Blair stood as he had risen, gazing westward where the other had departed, but seeing nothing, not even a shadow. Clouds had formed over the sky, and the night was of intense darkness. To attempt to follow a trail now was waste of time; and gradually, as he stood there, the unevolved fury of the man transformed. His tongue became silent; not a human being had heard the outburst. The physical paroxysm relaxed. As he returned to the ranch-house no observer would have detected in him other than the usual matter-of-fact rancher; yet beneath that calm was a purpose infinitely more terrible than the animal blaze of a few minutes before, a tenacity more relentless than a tiger on the trail of its quarry, than an Indian stalking his enemy; a formulated purpose which could patiently wait, but eventually and inevitably would grind its object to powder. Meanwhile, back at the scene of the tragedy, there had been feverish action. Many of the cowboys were already about the barns, and lanterns gleamed in the horse corral. Within the house, in the nearest bunk where they had laid him, stretched the proprietor of the ranch. About him were grouped Grannis, Graham, and Ma Graham. The latter was weeping hysterically--her head buried in her big checked apron, the great mass of her body vibrating with the effort. As Ben approached, her husband glanced up. Upon his face was the dull unreasoning indecision of a steer which had lost its leader; an animal passivity which awaited command. "Rankin's dead," he announced dully. "He's hit here." A withered hand indicated a spot on the left breast. "He went quick."
