LUMBER PRODUCTION BY CLASSES OF MILLS. 
The policy of arbitrarily dividing the reporting mills into classes 
according to the quantity of lumber cut was followed as in previous 
years. Table 2 shows, by classes, the computed 1 number of mills 
reporting and the computed total production for 1909 and for 1912

Fig. 1.— Relation of mill classes to production in 1917. 
to 1917, inclusive. The figures for 1909 are given for comparative 
purposes because of the exceptionally complete census obtained for 
that year and the belief held by many lumbermen that that year 
marked the high point in lumber production in this country. 
i "Computed," as used in this bulletin, expresses results obtained by the extension of figures based on 
actual returns so as to show totals for approximately all sawmills whether or not reports were received from 
them.
