Fine white dust hung in a sifting cloud above the wagon train, caking the nostrils of animals and men, blanketing the sides of oxen and horses, dusting a thin film over men and women. And the miles stretched on before them, endless and timeless. Red-rimmed and bloodshot eyes stared with dazed weariness into that limitless distance before them, seeing nothing to grip the eye or hold the attention. Long since all had been forgotten but the heat, the dust and the aching muscles. Each step lifted a powdery dust, stifling and irritating. It lay a foot deep on the plain, drowning the sparse grass and sage. Rock Bannon, riding away from the train alone, drew in his steel-dust stallion and turned in the saddle, glancing back at the covered wagons, sixteen of them in the long line with some led horses and a few outriders, yet none who rode so far out as himself, and none who appreciated their problems as thoroughly as he did himself. From where he sat he could not see their faces, but in the days just past he had seen them many times, and the expression of each was engraved in his mind.
