Abstract One indication of the progress of forestry is that growing record to which are added year by year the results of actual experience in the field of forest practice. Especially significant are those chapters of the record which describe the outcome of commercial ventures in forest management,for it is in the light of such concrete evidence that the forestry profession can design its efforts to promote the practice of forestry among timber owners. In this article the authors present a 12-year record cf one of the earliest sustained-yield enterprises in the Lake States region—a commercial selective cutting in hemlock-hardwoods in northeastern Wisconsin. The results are analyzed from both the financial and the silvicultural angles, and will be of interest to foresters and lumbermen alike.
