 Ontario I'^orestry I'ranch, British

 pulp and i)a])er comi)anies have done 

 some work alon^- similar lines, either in- 

 dependently or in co-operation with the 

 Comniission of Conservation. 



The research work of the Commission 

 of Conservation was started as early as 

 1912. when a survey was made of the 

 Trent Watershed area, Ontario, under 

 the direction of Dr. B. E. Fernow, Dr. 

 C. E. Howe and J. H. White. This study. 

 wliich was continued in 1913, revealed 

 much valualile data as to the conditions 



of regeneration on this lof^j^ed-over area, 

 much of which had sufifered seriously 

 fr(»ni repeated forest fires, with conse- 

 (|uent deterioration in the comjjosition of 

 the second <^rowth. The effect of re- 

 peated fires in redticinj:^ the occurrence 

 of wliiic- ])iiie in the re|^eneration was 

 ])articularl}- noticeable. 



In 1914. a sttidy was made by Dr. 

 Howe of the reproduction of commercial 

 s])ecies in the southern coastal forests 

 of B>ritish Columbia. This w^ork was 

 done in co-operation with the iJritish 

 Columbia I'orest Branch. One of the 

 conchisions was that lii^ht burnincc of 

 the loj^gint^- slash and of the dense under- 

 growth f(ives the best reproduction of 

 Doujj"las fir. The need w^as emphasized 

 for regulated slash-burning and for a 

 more rigid fire protection on the areas 

 already covered with young growth. 



Beginning in 1917, the Commission 

 inaugurated, under the immediate direc- 

 tion of Dr. Howe, a programme of in- 

 vestigation to determine what technical 

 measures are necessary to ensure the 

 perpetuation of the vast pulpwood 

 forests of Eastern Canada. In provid- 

 ing for these studies, a somew hat unique 

 development has taken place, under 

 which co-operation has Ijeen developed

 been logged practically clean, and slash-ljurning is under way, after a light snow-fall. The burning of 

 loggnig slash in piles, after a light fall of snow, is perfectly safe. The object of slash-burning is to re- 

 duce the fire hazard. Comparative studies are to be made through a period of years, of the natural re- 

 generation on areas handled under different methods of treatment. Photo by W. M. Robertson, Com-
