Alfred Russel Wallace,
Travels on the Amazon
“ The most striking features of the Amazon are—its vast expanse of smooth water, generally from three to six miles wide; its pale yellowish-olive colour; the great beds of aquatic grass which line its shores, large masses of which are often detached, and form floating islands; the quantity of fruits and leaves and great trunks of trees which it carries down, and its level banks clad with lofty unbroken forest. In places the white stems and leaves of the Cecropias give a peculiar aspect, and in others the straight dark trunks of lofty forest-trees form a living wall along the water's edge. ”
