LOBLOLLY OR NORTH CAROLINA PINE,

Table 26.-*Volumb in Board Feet (Circular-sawed 1-4 Inch Kerf) op Trees of Loblolly Pine 

 OF Different Diameters and Heights. No Allowance for Breakage, Excessive Crook or 

 Waste Which Amount to 25 Per Cent for 7 and 8 Inch Trees; 15 Per Cent for 9 and 10 

 Inch; and 5 Per Cent for 12 Inch. 



Trees Under 75 Years Old. 



*An operation in Gates County, North Carolina, yielded at the mill from two stands, one aver- 

 aging 45 years old (Quality site I), and one averaging 60 years old (QuaUty site II to III), the following 

 volumes in board feet (circular saw 1-4 inch kerf). As was to be expected, the younger trees, although 

 taller, gave the lower yield. 



The mill loss in this case could have been considerably bs.sened by a better disposition of log 

 lengths. Logs were chiefly cut in 16 foot lengths. By cutting more shorter logs fewer crooks would 

 have been left in the middle of the logs and the loss in slabbing reduced. In this operation there 

 was an average of 11 linear feet of sound stem, 5 inches and over in diameter at the small end left in 

 the tops. This additional volume, entirely box and cull, amounted to about 7 board feet (circular- 

 sawed) per tree.
