A Girl of the Limberlost, a novel by American writer and naturalist Gene Stratton-Porter, was published in August 1909. It is considered a classic of Indiana literature. It is the sequel to her earlier novel Freckles. The story takes place in Indiana, in and around the Limberlost Swamp, in the eastern part of the state. The Swamp was a large, nationally known wetlands region with streams that flowed into the Wabash River. It originally covered 13,000 acres. Even when this book was written, the wetland region was being reduced by heavy logging, natural oil extraction and drainage for agriculture. (The swamp and forestland eventually ceased to exist, though projects since the 1990s have begun to restore a small part of it) Wikipedia.
Gene Stratton-Porter (August 17, 1863 - December 6, 1924), born Geneva Grace Stratton, was a Wabash County, Indiana, native who became a self-trained American author, nature photographer, and naturalist. In 1917 Stratton-Porter used her position and influence as a popular, well-known author to urge legislative support for the conservation of Limberlost Swamp and other wetlands in the state of Indiana. She was also a silent film-era producer who founded her own production company, Gene Stratton Porter Productions, in 1924 (Wikipedia).
