"Years ago I remember my father, when he planted corn, he would plant it years later we listed it which made a deep furrow, but he would plant it. And when he did he would string wires from one end of the field to the other. And then they had little knobs on that wire. Every time it hit a knob, it would trip the mechanism, and it would drop either two or three kernels of corn. You had to make the rows 40 inches wide because you had to have that [width] for a horse to walk in."
