 horizontal columns was secured mathematically.* 



The same general method of harmonizing the values in col- 

 umns 3 and 4 of Tables 4, 5 and 6 was used. 



It was impossible to harmonize the linear foot values from

 apparent relationship seemed to exist. The method which was 

 employed in determining the linear foot values for the different 

 site qualities and diameter classes was similar to the Arbitrary 

 Group Method of computing volumes of woods. As 6" trees 

 yield only prop material, the linear foot values assigned to them 

 were almost identical with the true average secured by the
