LUMBER USED IN THE MANUFACTURE OF WOODEN 
PRODUCTS. 
By J. C. Nellis, Forest Examiner. 
The importance of the wood-working industries among the manu- 
facturing industries of the country is indicated by the fact that 
lumber-working plants, of all classes, consume annually 24| billion 
feet of wood. This is about 60 per cent of the annual lumber pro- 
duction of approximately 40 billion feet. The material is mostly lum- 
ber, but includes comparatively small quantities of veneer, bolts, 
and dimension stock. 
This report presents statistics showing the average annual con- 
sumption of wood by the wood-working industries in the United 
States. The basic data were secured by a series of State wood-using 
industry studies. Those for the more important States have been 
published separately. Although the State studies were begun in 
1909 and were not completed until 1913, a period of 12 months was 
made the basis for the statistics for each State, and the final figures 
for the whole country here presented are therefore a very good average 
of the demand of each industry and the demand for each kind of 
wood. 
Lumber usually is remanufactured to a greater or less extent be- 
fore use, and in this report the product of the sawmill is not consid- 
ered. However, planing mills operated in connection with sawmills 
manufacture large quantities of flooring, ceiling, siding, finish and 
other patterns which really are finished products, and such material 
accordingly is covered by the statistics. 
About 40 per cent of the annual lumber cut is not worked by plan- 
ing mills or factories into finished products. About one-fifth of this 
(in normal times) is exported, while the rest is used in general build- 
ing and rough construction. Though all construction lumber re- 
quires cutting to length to make it fit into place, this industry was 
not considered by the studies, which canvassed only the wood-working 
factories. All imported woods used by factories are included in the 
statistics.
