 various hardwoods used for making veneers in the northern hardwood 

 region :

The consumption for slack cooperage stave manufacture for the 

 same year was as follows:

111 terms of lumber, the aggregate annual consumption for all 

 purposes of these five hardwoods in the Northeastern and Lake 

 States alone is probably 5,500,000,000 board feet. Including the 

 amount not usable, and therefore left in the woods, or burned as 

 refuse or mill fuel, it undoubtedly exceeds 6,000,000,000 board feet, 

 or 12,000,000 cords. 



The depreciation both in extent and quality of the northern forests 

 through lumbering, fire, decay, insects, and other causes has already 

 been mentioned. Concurrent with the decrease in softwood timber 

 there has occurred a relative increase in hardwood exploitation, and 

 a similar increase in the cut of inferior hardwoods. From 1899 to 

 1912 the recorded annual lumber cut of northern hardwoods increased 

 from less than 10 to more than 22 per cent of the total lumber cut. 

 The increase in the several States is shown hi Table 9:

 of all species, from 1899 to 1912.
