LOG-VOLUME TABLES. 



Tables 30 to 35 inclusive are log-volume tables (for logs from trees under 50 years 

 in age), based on measurements of logs with corresponding mill tallies of lumber 

 actually sawed out. The North Carolina measurements were taken at a mill only 5 

 miles from the Virginia line, and are entirely adaptable to the region under consid- 

 eration. 



Tables 30 and 31 show the actual mill cut in board feet and percentage of the different 

 North Carolina Pine Association grades cut from butt, middle, and top logs of different, 

 diameters and lengths. 



Table 32 is based on the cut of a portable mill in Somerset County, Md. , and runs 

 slightly higher than Table 30, due largely to the fact that the lumber was not so. 

 carefully manufactured , it being sold ungraded and mill run. 



Table 33 shows the cut of small logs when sawed into crate flitch — i. e., plank 21- 

 inch thick, having one waney edge. The width measured in scaling is the average: 

 width on the narrow face. A comparison of this table with the preceding (Table 32) 

 shows that logs cut out more board feet of lumber when sawed into flitck than when 

 sawed into boards. The value of flitch per 1,000 board feet, however, isonly three- 

 quarters that of inch lumber.
