FORESTER'S REPORT. 79 



be better left open, and a tree that is sprayed carelessly or with 

 wrong material will be benefited as much as, and no more than, one 

 that is butchered under the pretense of being pruned. It is a sheer 

 waste of money to pay unknown men for work of this kind. And if 

 dead trees are to be sold it is well to remember that the wood is 

 not useless but usually has a value greater than is represented by 

 the cost of removing it. Tree owners and forest owners are warned 

 against men without credentials. Those who have work of this kind 

 to do are advised to seek assistance of the local Shade Tree Com- 

 mission, of the Forest Commission, of the State Entomologist or of 

 the State Plant Pathologist. All have knowledge of reputable 

 parties.
