Sven Anders Hedin, From Pole to Pole: A Book for Young People
“ Before us to the south-east small isolated hills stand up like islands in the sea, and beyond them the horizon of the desert lies as level as that of the ocean. Through this great sandy waste the caravans travel from oasis to oasis, but in the north there is a tract, called the Kevir, within which not the smallest oasis can be found. Not a clump of grass, not even a blade, is to be seen, for the desert is saturated with salt, and when it rains in winter the briny clay becomes as slippery as ice. ”
