THE FORESTS OF OREGON AND THEIR 

 INHABITANTS 



LIKE the forests of Washington, already 

 described, those of Oregon are in great part 

 made up of the Douglas spruce, 1 or Oregon 

 pine (Abies Douglasii). A large number of 

 mills are at work upon this species, especially 

 along the Columbia, but these as yet have 

 made but little impression upon its dense 

 masses, the mills here being small as compared 

 with those of the Puget Sound region. The 

 white cedar, or Port Orford cedar (Cupressus 

 Lawsoniana, or Chamcecyparis Lawsoniana), is 

 one of the most beautiful of the evergreens, and 

 produces excellent lumber, considerable quan- 

 tities of which are shipped to the San Fran- 

 cisco market. It is found mostly about Coos 

 Bay, along the Coquille River, and on the 

 northern slopes of the Siskiyou Mountains, 

 and extends down the coast into California. 

 The silver firs, the spruces, and the colossal 

 arbor-vitse, or white cedar 2 (Thuja gig anted), 

 described hi the chapter on Washington, are
