In twenty-first century America, those of us who live even in small towns often don't appreciate the convenience of the corner grocery store or the Wal-Mart Supercenter. At Fort Scott in the 1840s, the post sutler filled that role for the soldiers and civilians in the area. He provided goods that could not easily be obtained otherwise. He also served as the postmaster, barkeeper and news vendor. He traded not only with the military, but also with civilians and Indian tribes. By bringing these groups together in trade, he became an agent of civilization on the frontier.
Since there will be at least two students presenting this station, one should portray the post sutler; the other could be his wife or one of his customers, a soldier for example.
