3C SHADE TREES. 



"90. Before any trimming is done the consent of the owner of the tree 

 should be obtained.* Opposition to tree trimming may sometimes be over- 

 come by offering to employ a professional gardener for this purpose. If 

 consent to trim trees cannot be obtained, and the interfering branches 

 cannot be avoided by the use of longer crossarms, or by offsetting the 

 standard crossarms, tree wire shall be used." 



"91. The stubs of branches shall always be painted for their protection 

 and to make them less noticeable." 



"94. Where tree wire is used, if there is danger of limbs or large 

 branches chafing the insulation, it shall be protected by means of wooden 

 abrasion moulding."

INSECTS, DISEASES. 



These subjects are presented fully by Dr. Smith and Dr. 

 Cook in their accompanying papers. 



ABRASIONS, HORSE BITES. 



A tree whose bark is broken is hastened towards an early 

 death. Prevent such injuries by guards and by police regu- 

 lations. Be particular about the lawn mower. Half our 

 shade trees are repeatedly bumped and permanently injured 

 through wounds made at their bases. (See page 54.) If a 

 tree is so damaged have it treated promptly as directed on 

 page 44 and Fig. 20. 



*Where there is a Shade Tree Commission it has authority above the owner 

 and will help to adjust differences.
