OPERATIONS PRELIMINARY TO CONSTRUCTION

be trimmed sufficiently to allow at least a 4-ft. clearance of the line wire. Any dan- 

 gerous snags or rotten trees in the close vicinity of the line should be cut. A right-of- 

 way clearing for a tree line must usually be at least 8 ft. wide at the height above the 

 ground at which the wire will hang. This is quite different from an 8-ft. clearing 

 on the ground, particularly in long-branching species such as spruce, hemlock, and 

 cedar, but care must be taken to see that sufficient clearing is made before the wire 

 is strung, as otherwise annoying and costly delays result. 



In clearing lines through dense underbrush and reproduction, it will be found 

 most satisfactory to scatter the clearing crew singly along the line and have all

material felled into the right of way. The debris resulting from such clearing adds 

 to the fire-danger and should, if practicable, be burned on the right of way before the 

 wire is strung. If not practicable, the brush should be piled off the right of way and 

 left for burning at a time when conditions are favourable. 



Section 49 Transportation and Distribution of Materials 



The wire, brackets, insulators, and other equipment should be conveyed? from the 

 railway point or the place of purchase to the proposed line by automobiles, teams, or 

 horses. Time and money will be saved if construction work is ndt started until all 

 necessary line equipment has been distributed to its proposed location or to some con- 

 venient point. Wire and other metal should be kept off the ground. All line 

 materials should be distributed along the right of way well in advance of wire-string-
