total sawmill capacity; and these idle mills were 

 well scattered throughout the region (table 28). 



Of both idle and active mills, the Chelan-Colville 

 unit has the largest number, but many are small and 

 the Klamath Plateau unit with half as many mills 

 has a much larger capacity. The greatest con- 

 centration of mills, both by number and capacity, 

 is in the vicinity of Klamath Falls (fig. 31). East- 

 ern Oregon, with its greater area of forest land and 



timber volume, has a score more mills than eastern 

 Washington and more than double the sawmill 

 capacity. 



Lumber Production and Its Relation to Installed Saw- 

 mill Capacity 



The total installed capacity of all sawmills in 

 1937, computed for a year of 300 8-hour working- 

 days, was approximately 2.4 billion board feet
