﻿FOREST MANACHMKNT OF LOBLOLLY PINE. 



53 



Table 42 indicates the actual mill cut of small trees of different diameters and 

 heights when cut into 4-foot lengths and sawed into flitch or into inch boards. A 

 comparison of (his fable with Table 39 shows how much more lumber can be obtained 

 when cutting small trees into very short sections. 



Tables 43 and 44 show the grades of North Carolina pine rough lumber, in board 

 feet and per cent, actually cut from trees of different diameters 30 to 50 years in age, 

 based on measurements of logs and trees taken in the woods with corresponding mill 

 tallies of lumber sawed out. These measurements were taken in northeastern North 

 Carolina, 5 miles from the Virginia line.
