The Great Sioux Trail is a story of mountain and plain. The scene cast a singular spell, uncanny and exciting, over young Clarke. The sweep of plains on one side, and on the other the dim outline of mountains behind which a blood red sun was sinking, gave it a setting at once majestic and full of menace. The horizon, as the twilight spread over its whole surface, suggested the wilderness, the unknown and many dangers. The drama passing before his eyes deepened and intensified his feeling that he was surrounded by the unusual. The fire burned low, the creeping dusk reached the edge of the thin forest to the right, and soon, with the dying of the flames, it would envelop the figures of both Sioux and soldiers. Will's gaze had roved from one to another, but now it remained fixed upon the chief, who was speaking with all the fire, passion and eloquence so often characteristic of the great Indian leaders. He was too far away to hear the words, as only the the pulses in his temples beat hard and fast.
