 club, consult this Department. We 

 are ready to tell the results of experiences 

 along these lines in Brooklyn, Newark,

 several years ago where we had no 

 dead hickory trees in the park. Pre- 

 vious to that time there were from 

 two to three hundred hickory trees 

 dead annually in the park. Today we Q._i have a big oak tree on my

 with wire. Would like to know 

 if we can cure the diseased

 of wire netting of ^-inch 

 mesh. The work can be done 

 by an amateur as well as by 

 an expert.
