The victor leaned against the wall, his breath coming in great, sobbing gulps, his knees sagging and his head near bursting. He reeled across the wrecked room, gulped down a drink of whisky from the bottle on the shelf and, stumbling, groped his way to the outer air where he flung himself down on the ground, dazed and dizzy. When he opened his eyes the air seemed to be filled with flashes of fire and huge, black fantastic blots that changed form with great swiftness and the hut danced and shifted like a thing of life. Hot bands seemed to encircle his throat and the throbbing in his temples was like blows of a hammer. While he writhed and fought for breath a faint gunshot reached his ears and found him apathetic. But the second, following closely upon the first, seemed clearer and brought him to himself long enough to make him arise and stumble to his horse, and claw his way into the saddle. The animal, maddened by the steady thrust of the spurs, pitched viciously and bolted; but the rider had learned his art in the sternest school in the world, the "busting" corrals of the great Southwest, and he not only stuck to the saddle, but guided the fighting animal through a barranca almost choked with obstructions. Stretched full length in a crevice near the top of a mesa lay the other hunter, his rifle trained on a small bowlder several hundred yards down and across the draw. His first shot had been an inexcusable blunder for a marksman like himself and now he had a desperate man and a very capable shot opposing him. If Buck could hold out until nightfall he could slip away in the darkness and do some stalking on his own account. For half an hour they had lain thus, neither daring to take sight. Buck could not leave the shelter of the bowlder because the high ground behind him offered no cover; but the hunter, tiring of the fruitless wait, wriggled back into the crevice, arose and slipped away, intending to crawl to the edge of the mesa further down and get in a shot from a new angle before his enemy learned of the shift; and this shot would not be a blunder. He had just lowered himself down a steep wall when the noise of rolling pebbles caused him to look around, expecting to see his friend. Bill was just turning the corner of the wall and their eyes met at the same instant.
