ORNAMENTAL AND SHADE TREES

trees and limbs from Prospect Park 

 and kept up the examination and elim- 

 ination until we reached the point 

 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 

 have some splendid specimens of hickory 

 trees in the park, not at all infested, 

 while all around us thousands of hickory 

 trees are either dead or dying. 



When you are ready to start a tree 

 club, consult this Department. We 

 are ready to tell the results of experiences 

 along these lines in Brooklyn, Newark, 

 and other cities and we can furnish you 

 with suitable literature on the subject.

Ques. I enclose picture of a fine oak 

 to which horses are constantly tied, 

 but which I hope to protect 

 with wire. Would like to know 

 if we can cure the diseased 

 spots already affected. The 

 spots in the center of the 

 picture, just above the horse's 

 nose, are the worst places, 

 and I have seen bugs or ants 

 coming out in numbers . Could 

 a novice do anything at tree 

 surgery through advice by 

 correspondence ? Could any 

 acid treatment be applied to 

 arrest decay? I am quite 

 anxious our town should have 

 a Tree Club but so far efforts 

 have failed. The tree shown 

 in the illustration is in the 

 center of a side street where 

 it makes a welcome shade, 

 as shown by use. J. A. T.,

A. For ants or grubs, in- 

 ject carbon bisulphid with a 

 syringe or squirt can and im- 

 mediately after the injection 

 is made clog up the holes 

 with soap in order to retain 

 the deadly fumes generated 

 by the carbon bisulphid with- 

 in cavities. Then cover the 

 wound with coal tar and place 

 around the tree a guard made 

 of wire netting of J^-inch 

 mesh. The work can be done 

 by an amateur as well as by 

 an expert. 



Q. I have a big oak tree on my 

 property here in Hoboken, and the 

 tree, while a great ornament to ray 

 place, shows of late signs of sickness, 

 the top branches seeming to die out, 

 and I wish to find out what can be done 

 to save it, if possible. Shall be glad to 

 have you advise me. C. M. B., 

 Hoboken, N. J. 



A. Dead branches in an old oak 

 tree may be the result of various causes 

 of deterioration. The tree may be 

 suffering from a fungus disease on the
