doubles the industrial value of the lumber, and the plants manufacturing paper bags, 

 boxes, roofing paper, &c., materially enhance the sale value of the pulp and paper 

 they use. 



The total sale value of the products of the forest is approximately $530,000,000 

 annually. Of this the pulp and paper industry furnishes §219,000,000, the lumber 

 industry $111,000,000, unmanufactured woods products $80,000,000, and the finished 

 wood products SI 20,000,000. 



While Canada is a very large exporter of forest products, she is not entirely 

 self-supporting in this respect. In 1926 the imports of forest products were valued at 

 about $36,000,000. This is largely accounted for by the importation of expensive 

 hardwoods such as oak, walnut, mahogany, gumwood and some of the rarer woods 

 used particularly in the furniture industry. 



The lumber industry, which for many years was centred in eastern Canada, has 

 gradually shifted to British Columbia, untU now Douglas fir occupies first place in 

 Canada in the amount of material sawn. Douglas fir also figures very prominently 

 in the export trade of Canada on account of its pre-eminent position as a structural 

 and general utihty timber. 



The Federal Government of Canada, by the establishment of forest products 

 research laboratories, has been active in stimulating a more intensive and economical 

 use of wood. Beginning with one organisation in 1913, the work of these laboratories 

 has rapidly expanded until there are now three such institutions in the Dominion 

 Forest Service actively engaged in research in wood utilisation. The main laboratories 

 are located in Ottawa, with a branch laboratory in Vancouver, which concentrates 

 on the problems relating to British Columbia timbers, and a pulp and paper laboratorj' 

 located in Montreal, maintained in co-operation svith the Pulp and Paper Associa- 

 tion of Canada. This is probably the most completely equipped pulp and paper 

 laboratory in existence.
