III. — Report of the Liaison Officer 



Operations carried out during the past season include: — 



(1) Operations in connection with the use of flying. 



(2) Establishment of radio communication. 



(3) An investigation of lookout tower horizon map construction. 



(4) Improvement of photographic survey methods. 



(5) Classification of O.F.B. maps. 



Flying. 



The principal feature of the past season, from the standpoint of use as well 

 as operation of aircraft, has undoubtedly been the purchase of a specialized 

 type of machine for -fire detection. The type of machine purchased has proven 

 satisfactory and should appreciably reduce the cost of this type of aerial work. 

 These machines are not, however, suited to forest type sketching or oblique 

 photographic survey. 



Flying records of the past season, while showing a general similarity to 

 previous years, are distinguished by an increase from twenty-eight hundred to 

 just over four thousand hours, by far the greatest recorded in any single year. 



Of this twelve hundred hour increase fully two-thirds is chargeable to 

 transportation of fire-fighting crews and equipment, mainly in the Red Lake
