PRODUCTION OF LUMBER, LATH, AND SHINGLES IN 1918, 17 
mills reporting, the quantity reported cut, the proportion of the total 
reported cut, the average value per thousand feet f. 0. b. mill, and the 
computed total cut. The average values given in the tables are the 
weighted averages of about 50 per cent of the 14,753 mills which re- 
ported their cut, and accurately reflect the true value of the several 
species of lumber at the milJl. The variation in values for the same 
wood in different States is caused by character of timber, type of 
manufacture, and distance from market.

Fic. 3.—Computed total lumber production in 1918, by kinds of wood. 
The question is frequently asked in connection with lumber produc- 
tion figures as to what part shortleaf pine forms of the total quantity 
of yellow pine reported, or the ratio of white oak cut to the total. It 
is not practicable in the lumber census work to do more than group 
the figures for all of the yellow pines together, and treat the oaks, 
sums, cedars, and other woods in the same way, since no standard 
classification is found among the lumbermen. Producers in one sec- 
tion frequently apply a local name to a given species and only confu- 
sion would follow an attempt to segregate the figures.
