REPORT OF THE SOCIETY 69 



While the trees are being banded, any connections with infested locations 

 should be broken. Telegraph wires or branches interlocking with infested trees 

 may reinfest the clean trees after all ordinary- precautions have been taken ; and 

 it is therefore necessary to band telegraph and telephone poles whose wires have 

 any connection with the shade trees to be protected, or to cut out with trimmers 

 the branches which connect with the sources of infestation. 



Spraying Outfit. — For spraying city shade trees effectively it is absolutely 

 necessary to have an efificient spraying outfit. A power sprayer is required, cap- 

 able of giving from 400 to 600 pounds pressure, and with a pump capacity great 

 enough so that a solid stream may be held constantly from 65 to 85 feet up from 

 the nozzle. These requirements should be insisted upon when purchasing spray- 

 ing outfits for shade-tree work.
