SAW-TIMBER PRODUCTON. 



Information regarding the approximate amount of saw timber 

 contained in individual trees of different sizes is sometimes wanted. 

 The amounts shown in Table 7 are based upon the measurement of 

 438 longleaf pine trees in central Alabama, taking the logs above a 

 1-foot stump and down to a top diameter of 6 inches. Table 8 shows 

 the amount of lumber in logs from different parts of turpentined and 

 unturpentined trees.

a The grade is indicated by the smaller numeral shown above and to the right of the 

 numeral giving the number of crossties of the specified grade. For example : l 2 means 

 one No. 2 crosstie. The scale is for straight and sound trees, no allowance being made 

 for defect.
