PART 11. STATISTICS OF PRODUCTION AND VALUE. 
TOTAL LUMBER PRODUCTION. 
The quantity of lumber reported cut in 1920 by 15,978 mills was 
29,878,360,000 board feet. The output of 2,668 mills cutting less 
than 50,000 board feet each is not included in the reported cut. In 
addition, 2,483 mills were reported idle. 
The estimated total lumber production was 33,800,000,000 feet 
board measure. This is a decrease in production of 2.2 per cent 
from the 1919 figures of the Bureau of the Census and 27 per cent 
less than the estimated peak of production in 1907. The computed 
number of mills operating (23,24.2) is less than half the number can- 
vassed by the Bureau of the Census in 1909. 
The reported lumber cut, the number of active mills reporting, 
and the estimated annual total cut are given in Table 1 for each year 
since 1899 for which data have been compiled. The statistics are 
not directly comparable for all of the years, since the intensiveness 
of the canvass made in different years must be taken into considera- 
tion. In the enumerations for 1899, 1909, and 1919 field agents of 
the Bureau of the Census were employed which permitted the tabu- 
lation of the output of practically all mills from direct reports.

LUMBER PRODUCTION BY CLASSES OF MILLS. 
As in previous years, the mills were arbitrarily divided into classes 
according to the quantity reported cut. These classes are shown in 
Table 2, with the computed^ number of mills operating and the 
6 "Computed," as used in this bulletin, expresses results obtained by the extension of figures ba.sed on 
actual returns, so as to show totals for approximately all sawmills, whether or not reports were received 
from tliem.
