SERIOUS STATE OE THINGS 



The result of the publication 

 of "The Tree Doctor" has been; 

 its author has been called into 

 various states to make an ex- 

 amination of trees. This has 

 developed the serious facts that 

 not more than 10 per cent of our 

 trees are sound! Their diseased 

 condition comes either from neg- 

 lect or brutal treatment. Trees 

 are dying before they have at- 

 tained to a third of their natural 

 age. Out of this condition has 

 grown up the industry of u TREE 

 SURGERY." Intelligent young 

 men have been drilled in this 



work. The way that trees revive and respond to kind treatment is a 



marvel to those who are not acquainted with the wonderful forces of tree 



life. 



Here is a case of genuine " Rock Maple." The huge wound came 



from neglect. 



The first photograph shows 



the young ' ' Tree Doctors ' ' as 



they are tracing the rot up in- 



to the powerful arms and down 



the trunk, clear into the roots. 



The second shows the tree filled 



with portland cement. It took 



over four tons to fill the cavity. 



The treatment adds, probably, 



from one to t\vo hundred years 



of the life of the tree. 



Those desiring such work 



done should address
