The most frequently quoted explanation of Bartram's conversion to botany, however, is from Crevecoeur's account of a visit with John Bartram published in The Letters of An American Farmer, 1782. In this account, John pauses from his plowing long enough to observe a daisy growing wild in his field: "What a shame, said my mind, that thee shouldst have employed so many years in tilling the earth and destroying so many flowers and plants, without being acquainted with their structures and uses." Today, Bartram's Garden in Philadelphia is home to an amazing botanical collection including this Golden Raintree.
