The sand lay blue in the moonlight and the iron tires of the wagons rolled among the shapes of the riders in gleaming hoops that veered and wheeled woundedly and vaguely navigational like slender astrolabes and the polished shoes of the horses kept hasping up like a myriad eyes winking across the desert floor. They watched storms out there so distant they could not be heard, the silent lightning flaring sheetwise and the thin black spine of the mountain chain fluttering and sucked away again in the dark. They saw wild horses racing on the plain, pounding their shadows down the night and leaving in the moonlight a vaporous dust like the palest stain of their passing.
