Estimated from Census Bureau's lumber production total for Colorado's 1962 production (208 million 

 board feet, lumber tally) on the assumption that lumber production was distributed among sawmill size 

 classes in the same proportion as their reported saw log receipts. 



Sawmill size class estimated from saw log receipts rather than from lumber production. 



Lumber tally.
