Keith of the Border

The man was riding just below the summit of the ridge, occasionally uplifting his head so as to gaze across the crest, shading his eyes with one hand to thus better concentrate his vision. Both horse and rider plainly exhibited signs of weariness, but every movement of the latter showed ceaseless vigilance, his glance roaming the barren ridges, a brown Winchester lying cocked across the saddle pommel, his left hand taut on the rein. Yet the horse he bestrode scarcely required restraint, advancing slowly, with head hanging low, and only occasionally breaking into a brief trot under the impetus of the spur.
