Logs are usually cut from 2 to 9 inches longer than standard lengths of boards, to allow for waste in handling and manufacture. This additional length is disregarded in scaling. Log rules give the number of board feet in logs which are straight and sound. If logs are unsound, or otherwise defective, a certain allowance must be made by the scaler and the determination of the amount in board feet requires great skill. FOREST SERVICE SCALING. In a general way. Forest Service scaling practice is the same as that of the log scaling and grading bureaus and independent scalers of the region. It differs, however, in some particulars, which should be thoroughly understood by applicants for national forest timber; for the scale resulting from Forest Service practice, as a rule, is larger than that resulting from commercial scaling. 61361"--Bull. 711--18 2 Briefly, scaling, as practiced by the Forest Service, is the measurement of sound material in the log and relates to quantity rather than quality. National forest timber, therefore, is scaled in accordance with the defect in the log and not in relation to any particular grade of lumber it will produce. On the national forests in Alaska and west of the summit of the Cascade Mountains in Oregon and Washington, logs up to and including 32 feet in length are scaled as one log; lengths from 34 to 64, inclusive, are scaled as two logs as nearly equal in length as possible in even feet, and increasing the diameter of the second log according to the taper of the first. Greater lengths than 64 feet are scaled as three logs, making the division as nearly equal as possible in even feet. Timber sale contracts specify a definite overlength for trimming.
