Abstract There is evidence that the lumber industry is giving increasing consideration to permanent management of privately owned forest lands. This was manifested during the hearings of the Joint Congressional Committee on Forestry, of January 1940, when Wilson Compton, general secretary and manager of the National Lumber Manufacturers Association said that almost twenty years ago a brief survey of forest ownership succeeded in locating "only three large or substantial commercial timber ownerships that were deliberately and purposely attempting what we now refer to as sustained forest production or sustained yield forest management. Within ten years there were 619 and within ten years again, as of now, there are so many of them that we do not count them." The following paper was first presented before the Washington Section of the Society of American Foresters, and later, with some additions before the Western Forestry and Conservation Association at Portland, Oreg., on December 12, 1940. It is evidence of the intelligent interest stimulated by the principle of cooperation incorporated in the Clarke-McNary law. Moreover, it is built around belief of the lumber industry that good forestry is a local matter and therefore, any extensions of regulation should be local regulations administered under state law.
G. H. Collingwood (1941) studied this question.
