District, while the remaining one-third has been absorbed by survey require- 

 ments of various kinds. Regular patrol flying has remained at practically the 

 same figure as in 1926. 



Further reference to the increase in transportation flying in the Red Lake 

 district is perhaps hardly required, it being generally realized that conditions 

 in this section of the country require special methods and precautions. The 

 greater use of machines for surveys can be largely explained by the increased 

 experience of the observing staff, and also to a better appreciation on the part 

 of district officers of the information which they can procure. 



Some indication of the special administration problems confronting district 

 organizations in different sections of the province and of the diversity of the 

 information to be obtained by aerial survey can be obtained from a list of the 

 surveys undertaken during the past year. These include: — 



1. In the Sioux Lookout District: — 



A sketch map of 250,000 acres, to show — 

 (a) timber types; 

 (&) areas of high hazard; 



(c) location of lakes suitable for aerial suppression flying and the 

 country to be reached by canoe from them. 



2. In the Port Arthur District:— 



Location and examination of six Lookout Tower sites. 



3. In the Oba District: — 



(a) Photographic survey of a strip one mile on both sides of all railway 



rights of way. 



(b) Location of lakes suitable for aerial suppression flying and the 



country to be reached from them by canoe. 



4. In the Sault District: — 



(a) Photographic survey of forty townships. 



(b) Aerial sketching of poorly mapped areas to be patrolled during 



present season. 



5. In the Sudbury District: — 



(a) Photographic survey. 



(b) Aerial Sketching of poorly mapped areas to be patrolled during 



present season. 



(c) Location of all lakes suitable for aerial suppression flying and 



country to be reached from them by canoe. 



6. In the North Bay District: — 



(a) Photographic survey of poorly mapped townships. 



(b) Aerial forest typing. 



(c) Sketch map of area adjacent to Ferguson Highway. 



7. In the Parry Sound District: — 



Aerial photographic survey. f 



To the above, all of which was initiated by the district offices, must be 

 added an almost equal amount of flying to provide type maps as a basis for the 

 departmental forest survey in the Rainy River watershed. This work has 

 provided detailed information over an area of 3,000,000 acres; an increase of 

 1,000,000 acres over last year's work. 



Together with the continued satisfactory performance of regular fire patrols, 

 the information obtained by the above surveys constitutes the Branch's most 

 successful flying season.
