Sir Richard Francis Burton,
The Lake Regions of Central Africa…
“ In the long summer the climate much resembles that of Sindh; there are the same fiery suns playing upon the naked surface with a painful dazzle, cool crisp nights, and clouds of dust. The succulent vegetation is shrivelled up and carbonised by heat, and the crackling covering of clayey earth and thin sand, whose particles are unbound by dew or rain, rises in lofty whirling columns like water-spouts when the north wind from the Wahumba Hills meets the gusts of Usagara, which are soon heated to a furnace-breath by the glowing surface. ”
