The Susan M.L. Wales Journal (1887-1895) is a series of letters written by Wales to her sister, Annie Stratton, over the course of multiple journeys throughout Europe, the Middle East, and Northern Africa (1887-1888, 1891, 1893-1895). The letters describe the local sights and people, questions about goings-on at home, gossip about mutual acquaintances, and small drawings and watercolor paintings.
