The article presented below came to the attention of the editors of the Journal of Forestry only recently. It was originally delivered as a paper at a meeting of the Ecological Society of America, Vancouver, B.C., June 15, 1949. It was not published and hence has received little attention from foresters, the persons who are most interested in the subject. The use of fire as a tool in silviculture has long been debated. The article is being published in the Journal because, although not new, it appears to offer an unusually objective analysis of this controversial subject.© Society of American Foresters, Bethesda, MD.
