During the past thirty years Sweden has made great progress in developing a rational program of forest management. The state and county organizations and the legislation which made these organizations possible are described. Although there is little likelihood that county forest boards would be successful generally in the United States at the present time, it does not follow that there is no place for a somewhat similar type of board in this country. Mr. Lobdell's article will be found to be of great interest at the moment because of our far greater faith in the efficacy of national than in state forest legislation.

The prediction of volume growth in timber stands by means of a yield table offers certain unquestioned advantages over other growth-prediction methods, especially in its straightforward approach and ease of application. The normal-yield table, however—based upon stand age, and defining site in terms of height of dominant trees—has not been applied successfully to all-aged stands like those of the northern-hardwoods cover type, chiefly because of the variation in age among individual trees in the stand. A yield table for average well stocked stands of northern hardwoods in the Lake States, based on the average age and the average diameter of the main stand has been prepared by the author.

The problems concerned with the relation between soil characteristics and timber growing have received only sporadic attention from investigators in the United States until very recently. Even now, only a few individuals are able to devote all or a part of their time to forest soil research. Research in forestry has been going through the measurement and inventory stage; little attention being given to the complicated problems involved in the interaction between the soil and the forest. Many elaborate and involved investigations on growth, yield, and reforestation have been made; but their objectives have largely been the measurement of an existing condition without attempting to determine why it obtains.
