James Bruce,
Travels to Discover the Source of the Nile
(1790)
“ No sooner does the sun pass the zenith, going southward, than the rains instantly cease; and the thick canopy of clouds, which had obscured the sky during their continuance, being removed, the sun appears in a beautiful sky of pale blue, dappled with small thin clouds, which soon after disappear, and leave the heavens of a most beautiful azure. A very few days of the intense heat then dries the ground so perfecty, that it gapes in chasms; the grass, struck at the roots by the rays, supports itself no more, but droops and becomes parched. ”
