"Man may be civilized, in some degree, without great progress in manufactures and with little commerce with his distant neighbors. But without the cultivation of the earth, he is, in all countries, a savage. Until he gives up the chase and fixes himself in some place and seeks a living from the earth, he is a roaming barbarian. When tillage begins, other arts follow. The farmers, therefore, are the founders of human civilization.”

- Daniel Webster, 1840
