Volume Table for Lodgepole Pine. 323 



After the maximum and minimum heights for each site quality 

 and D. B. H. class were determined, the tree measurements were 

 gone over again, and the volumes in feet B. M. and the num- 

 ber of linear feet of props were grouped by diameters and site 

 qualities, totalled, averaged, and expressed in a semi-final table 

 of the following character: 



Tables 2 and 3 were similar to Table i except they showed 

 data for sites II and III respectively. In these operations the 

 gross scales instead of the "Defect Scales" were used, since a 

 table compiled from measurements of perfect trees is more valu- 

 able than one which includes the local average defect. In se- 

 curing the original data, defect deductions were only made to 

 ascertain how defective were the local Lodgepole pine stands. 



The method described above was employed in compiling the 

 semi-final tables for the tie measurements except that only trees 

 11" to 20 " in diameter were used, and the results recorded in a 

 semi-final table of the following character: 



Tables 5 and 6 were similar to Table 4 except they represented 

 data for sites II and III respectively. 



These six tables were made a permanent record, for by so 

 doing it will, with little office work, be easily possible to add 

 data on additional trees at a future date without tearing apart or 

 reworking the present data.
