Lardner Gibbon, Lieutenant, U.S.N., Exploration of the Valley of the Amazon… (1854)
“ A number of lakes are in the valley and on the mountains in the neighborhood of this city. During a dry time, no frogs are heard; but the moment the thunder roars, or the lightning flashes, they sing songs of thankfulness; the valley is made gay with their voices after rains. The wild ducks bathe in the calm waters, near the willow trees which shade the Indian’s hut, and is also adorned with sweet orange blossoms, while the dry barren hills are baked into crust, and the sheared sheep look half starved for want of pasture. ”
