feet, with an annual increment due to growth of 770,000,000 feet. 

 While it is probable that the maximum annual consumption of spruce 

 for lumber has been reached, and that that for pulp wood will scarcely 

 go much higher, it is nevertheless clear that with the maintenance 

 of anything like the present annual consumption the spruce forests 

 of this country are threatened with exhaustion. Nor is it likely that 

 the American consumer of spruce wood will be able to draw to what- 

 ever extent ho wishes upon the Canadian supply. In 1900 the 

 Province of Ontario prohibited the exportation of unmanufactured 

 wood cut on Crown lands within the Province, and later the Provinces

of Quebec (1909) and New Brunswick (1911) passed similar legisla- 

 tion. Further restrictive measures regarding the exportation of 

 unmanufactured wood will undoubtedly be taken by Canada if the 

 need arises. 



The rise in the price of spruce over the 10-year period from 1900 to 

 1909, inclusive, reflects a steady increase in the consumption of 

 mechanical pulp and a decrease in the available supply of the wood. 

 In 1900 the average cost of spruce used for pulp-making purposes in 

 the United States was $4.28 per cord for domestic and $6.50 per cord 

 for imported material. In 1909 the average price for domestic spruce
