PRODUCTION BY KINDS OF WOOD 



Table 4 on page 14 shows the reported kimber production by kinds 

 of wood for 1899 to 1914 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-

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.
