Excerpt from Grades and Amount of Lumber: Sawed From Yellow Poplar, Yellow Birch, Sugar Maple, and Beech The Forest Service has endeavored to determine, in typical localities and nudel good conditions of manufacture, the graded yield. And the money Value of some important Commercial trees. It should be borne in mind, however, that the figures obtained will i by no means fix absolutely the graded yield and the Value of the species studied over their entire range of growth. The character of timber changes in different localities and in different situations within the same locality; the conditions governing its logging, control the manner and extent of each tree's utilization; the demands of a given market regulate methods Of manufacture; the efficiency of the mill'and of the mill crew affects the quality and quantity of the products; and the nature and application of the grading rules determine results. Therefore the results from no two mills can be exactly similar. Nevertheless, figures suchas those given for yellow poplar, yellow birch, sugar maple, and beech give relatively, if not absolutely, the graded yield and the value of the species.
