William Hadfield, Brazil and the River Plate in 1868
“ The great exodus will as naturally flow into the vast arable area of the valley of the Amazon as did the tribes of Asia flow into Europe through the passes of the Caucausus.Every advancing wave of population will lift higher and higher the gathering flood of human life, which the moment it commences to press upon the means of subsistence in their respective countries must pour all of its vast tide of human beings into the great valley of the Amazon, and will eventually unite in one living chain of industrial life the waters of the Atlantic with the Pacific. ”
