Lardner Gibbon,
Exploration of the Valley of the Amazon…
“ The winds are very gentle, and curl the cirrus or hairy clouds in most graceful shapes about the hoary-headed Andes in rich and delicate clusters; when the peak is concealed, all but the blue tinge below the snow, we see a natural bridal veil. An easterly wind lifts and turns them to dark, cumulus clouds, settled on the frosty crown, like an old man's winter cap; the physiognomical expression is that of anger. The change is accompanied by thunder, and seems to command all around to clothe themselves for storms. The cold rain comes down in fine drops upon us ”
