The moon was high in the sky. The wind was laid. So silent was the vast stretch of mountain wilderness, aglint with the dew, that the tinkle of a rill far below in the black abyss seemed less a sound than an evidence of the pervasive quietude, since so slight a thing, so distant, could compass so keen a vibration. For an hour or more the three men who lurked in the shadow of a crag in the narrow mountain-pass, heard nothing else. When at last they caught the dull reverberation of a slow wheel and the occasional metallic clank of a tire against a stone, the vehicle was fully three miles distant by the winding road in the valley. Time lagged. Only by imperceptible degrees the sound of deliberate approach grew louder on the air as the interval of space lessened. At length, above their ambush at the summit of the mountain's brow the heads of horses came into view, distinct in the moonlight between the fibrous pines and the vast expanse of the sky above the valley. Even then there was renewed delay. The driver of the wagon paused to rest the team.
