xvi METHODS OF COMMUNICATION FOR FORREST PROTECTION 



Being intended for non-technical readers, it has been necessary in many instances 

 to elaborate points that might otherwise have been passed over very briefly. For the 

 same, reason a certain amount of repetition has been thought desirable. The aim has 

 been to bring together in one publication not only the details of telephone construction 

 and operation practice as exemplified on the Dominion forest reserves, but also all 

 available information on various communication methods that have proved to be 

 useful in connection with forest protection activities. It is believed that only one 

 subject of importance has been given very inadequate treatment and that is the 

 question of pole preservation. This, it is planned to treat in a supplementary 

 publication when certain investigations now being conducted are completed.
