TABLES. 



It has been the aim of the authors to gather together all the 

 reliable tables at present available, which contain figures showing 

 volumes and growth for the important commercial trees and 

 types. The principal log rules used in the region have also been 

 included. In connection with the practice of forestry such tables 

 are of great value, and it is unfortunate that as yet, owing to the 

 recent rise of the movement, more information has not been 

 obtained. The field is very incompletely covered and indeed for 

 many species data is entirely lacking. For white pine, com- 

 paratively full studies have been made and many valuable tables 

 are available. 



Except for Tables X, XV, XX, XXV, XXXII, XLV, XLVI, 

 LXVI and LXXV, none of the tables given here are original, 

 but have been taken from various sources, of which acknowledg- 

 ment has been made in the preface. Also, in connection with 

 each table will be found a statement as to the source from which 

 it was secured.
