 For veneers. U. S. 1921 : 



576,000 M ft. B. M. log scale. 



Based on log scale, a divisor of 6 is used for cubic feet = 96,000,000 

 cu. ft. 



For Illinois, no statistics on consumption of cooperage stock or 

 veneers are available, hence the quantity consumed must be obtained by 

 proportion from the total produced in the U. S. The result can only 

 be an approximation, but it is more accurate to include such an approxi- 

 mated total than to omit the item altogether. For total cooperage and 

 total veneers, then, the per cent consumed has been based, not on relative 

 population nor on the relative per cent of manufactures in the state to 

 total for U. S., namely, 8.12 per cent, but on the state's relative consump- 

 tion of lumber, which is 6.81 per cent, falling below the other two figures. 



Total cooperage, 1921 : 



168,628,500 X .0681 = 11,483,600 cubic feet. 



Total veneers, 1921 : 



96,000,000 X .0681 = 6,537,600 cubic feet. 



These quantities may be considerably in error on the basis that Illi- 

 nois consumes larger or smaller proportions of the total production than 

 those adopted. 



Shingles. 



The consumption of wooden shingles in Illinois was based on the 

 same percentage, namely, G.81 per cent of the total for the United States
