The object of the Agent’s thoughts passed unconcernedly on his way. He branched off the ford trail intending to make for the bridge, below which his men were cutting the timbers for the corral. His way was remote from the chief encampment, and not a single Indian showed himself.

The skeleton woods that lined the trail gave a desolate air to the bleak, white prospect. The whole of that northern world offered little promise to the traveler, little inducement to leave the warmth of house or tepee.

As the horseman neared the bridge he paused to listen. Something of his attitude communicated itself to his horse. The animal’s ears were laid back, and it seemed to be listening to some sound behind it. Whatever had attracted master and horse must have been very faint.

A moment later Seth let the horse walk on and the animal appeared content. But if the animal were so, its master was not. He turned several times as he approached the bridge, and scanned the crowding branches on each side of the snow-covered trail behind him.

Seth knew that he was followed. More, he knew that the watcher was clumsy, and had not the stealth of the Indian. At the bridge he faced about and sat waiting. The gravity of his face was relieved by a slight smile.

Suddenly the crack of a rifle rang out. The horseman’s smile died abruptly. His horse reared, 216 pawing the air, and he saw blood on the beast’s shoulder. He saw that the flesh had been ripped by a glancing bullet, and the course of the wound showed him whence the shot had come.

He looked for the man who had fired, and, as he did so, another shot rang out. He reeled forward in his saddle, but straightened up almost at once, and his right hand flew to his revolver, while he tried to swing his horse about. But somehow he had lost power, and the horse was in a frenzy of terror. The next moment the beast was racing across the bridge in the direction of home.

The journey was made at a great pace. Seth was sitting bolt upright. His face was ashen, and his eyelids drooped in spite of his best efforts.

Rube was in the region of the kitchen door as he galloped up, and he called out a greeting.

The rider began to reply. But, at that moment, the horse propped and halted, and the reply was never finished. Seth rolled out of the saddle and fell to the ground like a log.
