and large poles from 8 to 12 

 inches in diameter. ( See figs.

 standards, and finally, all 

 trees over 2 feet in diameter 

 are veterans. (See figs. 34,

It is very important to re- 

 member that all these diam- 

 eters are measured breast high, or at the height of a 

 man's chest, about 4 feet 6 inches from the ground. In 

 forestry this is, roughly speaking, the general custom.
