During the manufacture of mountain hardwood lumber it was shown that sawing extra thickness (over 4/4) at band mills increased the dollar value an average of $ per The effect varied with species as shown by the following tabulation. Species Increase (Dollars per ) Yellow-poplar Ash, birch, buckeye, scarlet oak, sugar maple, and red maple Black cherry, chestnut oak, and white oak Northern red oak, and black oak Beech Average of all species A mill-scale study was made of the grade-yield of mountain pine logs for a location in North Carolina. The differences in percentage grade-yield between this study and both the Piedmont and Coastal Plain mill-scale studies.
