Book excerpt: Excerpt from Veneer Yields by the New Timber Cruising Grades for Old-Growth Coast Douglas-Fir An adequate log or tree grading system for a given species is developed from analytical studies of timber characteristics and their relationship to-end product yields and values. The new log grading system for Douglas - fir, on which these recovery data are based, is that type of system. Recent publications (4, 6) give lumber and veneer yields based on the present Forest Service sawmill log-peeler log grading criteria for Douglas - fir. The study trees were selected to be representative in size and quality of west - side commercial Douglas-fir timber. Logs from these trees were not intended to be representative of the typical log mix at a mill. Logs were bucked, sawn, and peeled according to normal practice at each study mill. Public agency check scalers or scaling supervisors scaled all study logs according to uniform Bureau rules._1/ These rules are described as Forest Service instructions for west - side log scaling and grading. The lumber was graded by, or under the direct supervision of, a quality supervisor of the Western Wood Products Association, West Coast Lumber Inspection Bureau, or the Pacific Lumber Inspection Bureau. All veneer was graded by, or under the supervision of, the American Plywood Association or the Timber Engineering Company quality supervisors.
