an unprotected state, than the wood of any of the other native firs. 

 The color is yellowish brown, with a reddish tinge. It has good working 

 qualities, which should render it useful for a number of purposes to 

 which the pine is put. 



ILAWSON CYPRESS. 

 Oregon and California produce all the Lawson cypress lumber that 

 is utilized; but, in 1910, Oregon produced 27J million feet, board 

 measure, whereas the amount cut in California was too small to report. 

 This species (known also as white cedar and Port Orford cedar) 

 ranges from the northern border of the State southward within the fog 

 belt, to Mad River, Humboldt County, extending from within a few 

 miles of the sea to points from 10 to 40 miles inland ; ascending the sea- 

 ward slopes of the Coast Range to 5,000 feet elevation. It is not 

 abundant in California, and but 515 million feet of live saw timber are 

 found in the National Forests within the State. 



The height that the tree attains commonly varies between 135 and 

 175 feet, and the diameter between 3 and 6 feet. 



The wood is light and moderately strong; the grain fine, even and 

 compact ; and the color light yellow or almost white, though occasionally 

 reddish, the thin sapwood being hardly distinguishable. It is abundant 

 in odoriferous oil, distasteful to insects and vermin; and is susceptible 

 of a beautiful polish, as well as easily worked and durable. 



YUCCA. 



This species ranges from the southern base of the San Bernardino 

 Mountains to the coast, and northward to Monterey, sometimes ascend- 

 ing mountain slopes to 4,000 feet elevation. 



The trees are usually under 10 or 12 feet in height, and seldom over 

 10 inches in diameter. 



The wood, pale yellowish white in color, is rather soft and light when 

 dry, but tough because of its strong fibers. The manufacturers of 

 Yucca products will accept no tree under ten inches in diameter; and, 

 after turning off the veneer, they leave a core five inches thick. 



BLUE GUM. 



This species was introduced from Australia in 1856. It reaches its 

 greatest development along the coast, and in river bottoms, where foggy 

 days are common and the annual rainfall at least 15 inches. When 

 grown under favorable conditions it ranks among the fastest growing 

 trees in the world. 



The wood is yellowish white and easily polished. The fibers are 

 much interlaced, making it tough and difficult to split. The grain is 

 often irregular, which makes the wood liable to chip under the planer, 

 but gives it a very pleasing effect when smoothly finished. 



So far it has been used successfully only where specially selected 

 trees are sawed, and the lumber carefully air-seasoned for long periods.
