Before the Quebec Forest Protective Associa- 



Airplanes tion, ]\Iajor Kennedy, of the Royal Flying Corps, 



for discussed the adaptability of flying machines to 



Forest forest protective service. According to his figur- 



Protection ing. with rather extravagant salary list, he came 



to a charge of 2 cents a square mile, or 20 cents 



per lineal mile. The account was made up as follows : 



3 hydroplanes (i reserve) and shed $25,000.00 



At 10 per cent interest and 6 months' use 13.88 per day 



Daily flights of 5 hours for 6 months, 800 lineal miles, looking 

 over 8,000 square miles — 



2 aviators, salary by the year, $7,000, or 38.88 per day 



3 mechanicians 12.00 per day 



Petrol and oil 16 . 80 per day 



Total $81 . 56 



[This would make the cost nearer i cent than 2 cents per square mile.] 



The speaker pointed out that only first-class machines should be 

 used; that these should be "pushers," having the propeller in the back 

 to give the observer in the front free field ; that it should be a slow- 

 flying, slow-landing type. 



Equipped with a wireless telephone (not telegraph), this should make 

 a first-class equipment for a large-enough concern.

Jolyet, in discussing the rehabilitation of the

Forests and economic point of view. 



in He announces that in territory where conifers 



France are not spontaneously present in the hardwood 



forest it is imprudent to plant them in pure 

 stands. Altogttlur. from the economic point of view, the hardwoods 

 should be ])rei)ondc'rant, even as fuel not any more to be despised after 

 the e.xperienccs of the war. He hopes also the distillation industry to 

 develop niort- i'xtensi\c'ly. 



Mixed forest is recommended to be grown in such a manner that 

 after the conifers are utilized the liardwortds will form the forest — 

 that is. a small number of coniferous trees in a hardwood base. This
