AIRCRAFT AND TIMBERLANDS 



By Stuarl Graham, Manager, Aviation Department, 

 The St. Maurice Forest Protective Association, Limited. 



Although lumber concerns have been rather 

 pessimistic as regards the use of aircraft in 

 forestry work, yet it is safe to predict that the 

 time is not far distant when all large concerns 

 will operate 'planes over their limits. 



However, unless great care is exercised in the 

 selection of machines and personnel, the pes- 

 •^lmlsts will certainly win the day. 



There are two broad classifications of air- 

 craft, machines fitted with wheels for alighting 

 on terra firma, and those constructed for alight- 

 ing on water. The land machine is light and 

 more efficient as regards fuel consumption, but 

 owing to the lack of suitable fields for landing. 

 it must be disregarded for our forestry work, 

 lor the flying boat or seaplane the Creator has 

 ii^iven us thousands of square miles of perfect 

 l.inding area, free from the cost of mainten- 

 ance. 



SA\ES THE boss's TIME. 



Aviation has greater opportunities in forestry 

 work than in any other commercial enterprise. 

 The logging superintendent wishes to visit oper- 



ations a hundred miles from headquarters; the 

 trip generally keeps him away from the office 

 four or five valuable days. In place of this 

 delay, he makes the trip by air, and alights 

 on the shore of a lake a couple of miles from 

 the site of the operations two hours after leav- 

 ing home; he makes his inspection and returns 

 home the same day. During the trip the avia- 

 tor was not merely acting as chauffeur, but per- 

 formed a double fire patrol over two thousand 

 square miles of territory, and, if the weather 

 proved favorable, made aerial photographs of a 

 hundred square miles of country which prob- 

 ably had never been mapped, and only very in- 

 adequately explored. 



RE.SULT.s IN MAPPING. 



Let us site another instance: an explorer is 

 sent to make a detail report of a certain area 

 of timberland. Before doing his ground work, 

 he flics over the district, where he is able to 

 study the relief map beneath him. making full 

 notes of drainage, "burnt over. ' swamps, and 

 density and types of growth. Whilst enabling
