the PACIFIC NORTH WEST 
Montana and Wyoming the species are Douglas fir, 
lodgepole pine, yellow pine, and some species of less 
importance. Lodgepole pine occasionally grows large 
enough lor saw logs but usually it is best suited for rail¬ 
road ties and mine timbers. It is largely used for these 
purposes. I he chief forest industry of Wyoming is in 
the utilization of lodgepole pine for railroad ties. 
National Forests Protect Reserves 
About two-thirds of the great forests of the Pacific 
Northwest are owned privately, while one-third are 
owned by the Federal Government in the various 
National Forests shown on the map in the center of this 
book. The National Forests were set aside to insure 
the permanent production of timber, to protect the 
watersheds of navigable streams, and to preserve water 
supplies for cities and for irrigation and power. Sales 
of timber from these forests on long time leases are made 
by the government to private concerns.
