Canadian Forestry Journal, December, 1919 



a trolley line wire is supported overhead in the 

 middle of a street. The wire is thus kept free 

 from contact with the brush on each side of the 

 portage road. Any overhanging branches are 

 trimmed off with a special tree trimmer which 

 easily removes branches up to 2 inches in diam- 

 eter. The main line is kept reasonably tight 

 by being snubbed to a tree by a strain insula- 

 tor once ever yhalf-mile. Sufficient slack is 

 left in the wire to allow several trees to fall 

 across it and bring the main line to the ground 

 without breaking it or its supports. When the 

 fallen tree is cut out the line springs up to its 

 place. If the main line is not broken messages 

 may be sent over it even if several trees are 

 lying across the wire. Telephones are being in- 

 stalled at convenient points about ten miles 

 apart.
