TIMBER BILLIONS 
The preponderant strength of states in the Pacific Northwest 
is shown in this comparison of the principal timber states. 
Y\ estern yellow pine—sometimes known in the lumber 
trade as western pine—is found throughout the Pacific 
Northwest but the heaviest stands are in central and 
eastern Oregon and in parts of Montana and Idaho. It 
has long been a wood of recognized value for all sorts of 
uses. It competes now in the markets of the central 
states, and to a less degree in the eastern states, with 
the yellow pines from the southern pine region. 
World’s Largest White Pine Forest 
The largest forest of western white pine in the world 
is found in Northern Idaho and lapping over somewhat 
into western Montana. It contains 20 billion feet— 
three-fourths of the white pine in the United States. It 
is the occurrence of this species that is responsible for 
the building up of the lumber industry there. From the 
standpoint of general utility as well as value, there are 
few substitutes for white pine. 
Western larch, however, is the distinctive tree of 
western Montana, and with western yellow pine and 
Douglas fir it makes up the principal commercial forests 
there. Larch is used principally as a heavy construction 
timber. On the east side of the Continental Divide in
