120 REPORT OF THE No. 7 



miles were sketched. This included 560 square miles of Haliburton County, and 

 1,800 square miles of the north-east corner of the Nipigon Reserve. 



A considerable portion of the hours flown represent ferrying to and from 

 the areas to be sketched, which could not be avoided under the circumstances 

 brought about by the fire hazard period, especially in the Nipigon District where 

 the machine reported back to its base. Orient Bay, daily, to perform any duties 

 required by the ground forces. 



Photography. 



The Vickers' Vedette, which was purchased by the Branch primarily for 

 the photographic duties, performed and carried out the flying in connection with 

 the oblique and vertical photographic programme as was expected. Unfor- 

 tunately this particular aircraft was repeatedly called upon to perform suppression 

 duties which naturally has priority; thus the photographic programme laid down 

 for the season was interfered with. Of the 207.45 flying hours required in connec- 

 tion with the topographical survey 182.50 hours were devoted to vertical photo- 

 graphy, covering 900 ; quare miles, and 24.55 hours to oblique photography, 

 covering 1,000 square miles; making a total of 1,900 square miles. 



These hours do not represent the hours spent in actual photography. A 

 large percentage was taken up in ferrying to and from operating bases and 

 gaining the required height. 



Moth aircraft were employed ;n the photographic programme. Most of 

 this work was, however, of a preliminary nature, such as plotting the area 

 accurately on the maps and permitting the forester to become thoroughly 

 acquainted in preparation for suitable weather conditions and the arrival of 

 the photographic machine, the Vedette. 



The Vedette accomplished three times as much work than the other air- 

 craft heretofor flown in connection with the photographic programme. This 

 machine is adapted to photog.aphy, both from the pilot's and operator's stand- 

 point. 



Photographic aircraft were employed as follows : —

1. S.E. corner Mississagi Forest Reserve. West to Helen Lake, south to 

 Lake Superior. Total 560 square miles. Operated from Orient Bay base. 



2. S.E. corner Mississagi Forest Reserve. Total 180 square miles. Operated 

 from Bisco. 



Moth.

During the operating season of 1929 a total of 523.10 hours were devoted 

 in transporting machines to and from their various operating bases and to and 

 from Sault Ste. Marie, the outgoing and returning aircraft of the season's flying 

 activity.
