Timber is the great source of industry at present, the county having
about two-thirds of its area heavily covered and unexploited. About
40 saw and shingle mills are engaged in disposing of its logs.
Agriculture follows close on the heels of the lumberman everywhere
in western Washington, and nowhere are better results in general
farming and dairying obtained than in Cowlitz county.
Cowlitz coal fields have not yet been largely utilized, but will
be extensively developed in time.
