In the past few years, the Botany Department of Buter University has conducted an extensive study of Indiana peat bogs. Such a study will throw much light upon the history of Indiana vegetation. This paper is a portion of the greater survey and describes results from the southernmost bog studied. The name "Bacon's Swamp" has its origin by common usage of natives of the region. The area is a typical glacial peat bog of the kettle hole type, and is in no sense a swamp.
