PREVENTION OF INJURY TO DYING AND DEAD TREES. 



A large percentage of the injury to the wood of insect, fire, and 

 lightning killed trees and those killed or dying from injuries by 

 storms, disease, etc., can be prevented as follows: 



(1) By the prompt utilization of such timber within a few weeks 

 or months after it is dead or found to be past recovery. 



(2) By removing the bark from the merchantable portions of the 

 trunks within a few weeks after the trees are dead (the work to be 

 done either before or after the trees are felled). 



(3) By felling the trees and placing the unbarked logs in water. 



(4) By the adoption of a system of forest management which will 

 provide for the prompt utilization of all trees which die from any 

 cause.
