VOLUME-TABLES 



During the few months spent in taking mea- 

 surements of the White Pine 160 trees were com- 

 pletely analyzed. In addition, some 60 speci- 

 mens of other species growing in mixture with 

 the White Pine were measured in order to ob- 

 tain the course of the growth of height. The 

 method of tree-analysis was as follows : 



After each tree was felled and cut into logs, 

 the following measurements were taken : 



Distance of each cut from the ground. 



Total length. 



Length of the green crown. 



Lumber length. 



Clear length. 



Number of logs actually taken in practice. 



Thickness of the bark at each cut. 



Age and width of the sap-wood at each cut. 



Number of annual layers at each cut, count- 

 ing inward from the bark on an average 

 radius, and marking each ten-year point. 



Distance from the periphery to each ten-year 

 point.
