SHADE TREES AND THE LAW 247 



public service corporations must not be allowed to damage 

 trees through the stringing of wires, the laying of pipes or 

 in any other way. 



Some states have tried to curb incompetent tree 

 workers by a system of licenses based on examination. 

 This would be a help where there is not a thorough system 

 of tree supervision as there is in Massachusetts and would 

 be a help to private individuals wishing to have work done 

 on their own grounds. 



When appropriations are insufficient to meet reason 

 able demands the issuing of permits to responsible and 

 competent firms or adjoining property owners for planting 

 or pruning puts the work on a wrong basis, but is better 

 than no control.
