l~he northeastern states as lumber producers have held their 

 own remarkably well ; producing approximately the same amounts 

 of lumber annually in every year since 1870. 



The Lake states have shown in 1875 an output of lumber 

 equal to that of the northeastern states ; have reached highwater 

 mark in 1898, with an output of almost 9 billion feet board 

 measure ; and have since dropped down, like falling stars, to 

 the same annual output which was reported for them in 1875. 

 The southern states and the Pacific states play a most impor- 

 tant role as lumber producers. From 1870 on, the flight upwards 

 of the southern states has been more phenomenal than that 

 of the Lake states in days past. The southern states have doubled 

 their output between 1870 and 1880; have doubled it again 

 between 1880 and 1890; have more than doubled it for a third 

 time between 1890 and 1900, and are reaching now-a-days the 

 zenith of their lumber production with about 20 billion feet 

 board measure of lumber annually produced. 



The production of the Pacific States has taken a spurt upward 

 ten years later than that of the Southern States, namely in 1880. 

 The production of the Pacific States has been increased, however, 

 more slowly; during the period lying between 1907 (16.8 billion 

 feet b. m.) and 1909 (15.5 billion feet b. m.} it seems to have 

 declined temporarily. 



The Pacific States are far from havinp" reached the zenith of 

 their commercial timber production. When reaching it, their 

 production is apt to exceed the present highwater mark of 

 production shown in the southern states. 



The participation of the various sets of states in the total 

 commercial timber production of the U. S. since 1850 is shown 

 by the following tabular statement:
