In 1775 the British captain of engineers Thomas Hutchins, after having traveled the Great Lakes, the Ohio, and the Mississippi in 1762, prepared this map of the formerly French territory, then British. It incorporated the thriving towns Kaskaskia and Cahokia, with Fort de Chartres for protection. The soil of these bottom lands is alluvial and of astonishing fertility, and will become known as the American Bottom [Collection of Ulrich F. Danckers, M.D.].
