Once he paused, blinded by the snow, flung up his arm, and fired, imagining he saw the dim shape of a man on the ridge summit. There was no return shot, no visible movement. Reckless, mad with rage, he sprang up the wind-swept side, and reached the crest. It was deserted, except for tracks already nearly obliterated by the fierce wind. Helpless, baffled, the Sergeant stared about him into the driving flakes, his ungloved, stiffening hand gripping the cold butt of his Colt, ready for any emergency. Nothing but vacancy and silence encompassed him. At his feet the snow was still trampled; he could see where the man had kneeled to fire; where he had run down the opposite side of the hill. There had been only one--a white man from the imprint--and he had fled south, vanishing in the smother.
It required an effort for the Sergeant to recover, to realize his true position, and the meaning of this mysterious attack. He was no longer numb with cold or staggering from weakness. The excitement had sent the hot blood pulsing through his veins; had brought back to his heart the fighting instinct. Every desire urged him forward, clamoring for revenge, but the aroused sense of a plainsman held him motionless, staring about, listening for any sound. Behind him, down there in the hollow, were huddled the horses of his outfit, scarcely distinguishable from where he stood. If he should venture farther off, he might never be able to find a way back again. Even in the gray light of dawn he could see nothing distinctly a dozen yards distant. And Wasson had the compass. This was the thought which brought him tramping back through the drifts--Wasson! Wade was dead, Carroll little better, but the scout might have been only slightly wounded. He waded through the snow to where the man lay, face downward, his hand still gripping the rein. Before Hamlin turned him over, he saw the jagged wound and knew death had been instantaneous. He stared down at the white face, already powdered with snow; then glared about into the murky distances, revolver ready for action, every nerve throbbing. God! If he ever met the murderer! Then swift reaction came, and he buried his eyes on the neck of the nearest horse, and his body shook with half-suppressed sobs. The whole horror of it gripped him in that instant, broke his iron will, and left him weak as a child.
But the mood did not last. Little by little he gained control, stood up again in the snow, and began to think. He was a man, and must do a man's work. With an oath he forced himself to act; reloaded his revolver, thrust it back into the holster at his hip, and, with one parting glance at poor Sam, ploughed across through the drifts to Carroll. He realized now his duty, the thing he must strive to accomplish. Wade and Wasson were gone; no human effort could aid them, but Carroll lived, and might be saved. And it was for him alone now to serve Molly. The sudden comprehension of all this stung like the lash of a whip, transformed him again into a fighter, a soldier of the sort who refuses to acknowledge defeat. His eyes darkened, his lips pressed together in a straight line.
