Cyril G. Hopkins, The Story of the Soil; from the Basis of Absolute Science and Real Life
“ Have not England, Germany and France run their lands down until they produce only fourteen bushels of wheat per acre and have we not steadily built ours up to an average yield of thirty bushels? Other peoples wear out their soil because they fail to have part in the evolutional movement; whereas, did we not come to America and at once begin to make our rich land richer than it ever was in the virgin state? Do you not know, Sir, that the oldest lands in America are now the richest, most productive, and most valuable? ”
