Abner E. Woodruff, Evolution of American Agriculture (c/1919)
“ The check rowing corn planter cut the labor of planting corn in half and enabled crass cultivation of the crop, and a greater production in consequence. In the semi-arid region the lister was adopted for corn planting and, by getting the corn deep, assured moisture for the plant and an almost certain crop. Other tools were devised to lighten the labor of cultivation, with a corresponding increase of the production per man. ”
