PRODUCTION BY KINDS OF WOOD 
Table 4 on page 14 shows the reported lumber production by kinds 
of wood for 1899 to 1911 and similar computed totals for 1915. 
There is thus indicated the trend of production in each of the 
important kinds of lumber. The more accurate 1915 estimates for the 
exclusive western species are due to the closer touch of the western 
offices of the Forest Service with the small number of western mills 
as compared with the many thousands in the eastern half of the coun-

Fig. 4. — Computed total lumber production in 1915, by kinds of woods 
try. It will be seen, as in Table 3, that, in general, the production of 
those woods cut in the Northeastern, Lake, and Central States is de- 
clining, while the production of those cut in the Southern and North- 
western States is increasing. This, of course, does not hold true in 
every case. For instance, the fluctuating markets of 1914 and 1915 
caused Douglas fir production to drop but spruce to rise. 
Figure 4 is a graphic representation of the 1915 lumber cut by 
kinds of wood.
