along its far-flung other edges, this barren waste of dreary sand and grisly alkali was a vast, simmering playground for dancing heat waves and fantastic mirage, and its treacherous pools of nauseous, alkaline waters shrunk daily from their encrusted edges and gleamed malignantly under a glowering, molten sun. Arroyos, level plain, shifting sand, and imponderable dust, with a scrawny, scanty, hopeless vegetation which the whimsical winds buried and then dug up again, this high desert plateau lay like a thing of death, cursing and accursed. It sloped imperceptibly southward, its dusty soil gradually breaking into billowy ridges constantly more marked and with deeper troughs, by insensible gradations becoming low sand hills, ever growing more separate and higher until at last they were beaten down and strewn broadcast by more persistent winds, and limited by the firmer soils which were blessed with more frequent rains to coax forth a thin cover of protecting, anchoring vegetation. To the west they intruded nearly to the Rio Pecos, a stream which in almost any other part of the country would have been regarded as insignificant, but here was given greatness because its liquid treasure was beyond price and because it was permanent, though timid.
