METHODS OF COMMUNICATION FOR FOREST PROTECTION 



In nearly all the western provinces the use of the public roads as the right of 

 way for telephone lines is controlled by the provincial government. Before any lines 

 are placed on such roads permission must be secured from the proper government 

 department. This must in all cases be taken up through the district inspector. 



If it is desired to string wire on poles belonging to a private company written 

 permission should be secured from the inspector before any construction is begun. 



Section 48 Clearing Right of Way 



When a pole line is to be constructed, a right of way sufficiently wide to afford 

 reasonable protection against dlamage to the line from falling trees must be cleared. 

 It is especially necessary that dead or defective trees that lean toward the right of 

 way and threaten to fall across it be removed. The effect of snow on adjacent trees 

 and branches must always be considered, and all that might be borne down across the 

 line should be cut. As a rule pole lines will not be built in the forest if a cleared 

 right of way of greater than 25-ft. width is needed, unless the trees are exceptionally 

 scattered.

When pole lines are carried through small timber or reproduction a right of way 

 at least wide enough for a saddle trail should be cleared through any dense under- 

 brush. Small trees directly under the wire, which by their future growth might touch 

 the wire, should be cut down at the outset. Everything, in fact, that might at pre- 

 sent or in the near future cause trouble on the line should 1 'be cleared before or at the 

 time the wire is strung. 



If the line is to be attached to trees it is not advisable or necessary to top the 

 trees to which the split insulators are fastened, except where the line has to cross over 

 a windy canyon or in other places exposed to a strong wind. Under such conditions 

 the trees should either be topped or else poles used, preferably the latter. It is usually 

 only necessary to trim the branches on the insulator side of the tree to a sufficient 

 height for attaching the split insulator. Undergrowth and trees between spans should
