é N. B.—The figures in column 4 of the table give what an average tree of a certain 
diameter should actually saw out at the mill. The difference between what it saws out and 
its scale in the woods or on the log-deck is called “‘over-run."’ The figures in column 2 were 
derived from contents of trees measured at Ava, Jackson county, scaled by the Maine rule. 
The figures in column 3 of the table were secured from State Forester F. W. Besley, for white 
oak trees in Maryland which were scaled by the Maine rule.
