Habitat. — Oregon, Cascade and coast ranges, from the head of the 

 Mackenzie Piver and the valley of the Rogue Iliver, south along the 

 western flank of the Calif ornian sierras, through the coast ranges to the 

 Santa Lucia Mountains, and in the San Bernardino and Cuyamaca 

 Mountains. 



A large tree, 150-300 feet in height, with a trunk 10-22 feet 

 in diameter ; most common, and reaching its greatest development, 

 upon the sierras of Central and Northern California between 4,000 

 and 8,000 feet elevation ; in the Oregon coast ranges descending to 

 1,000 feet above the sea-level. 



Wood very light, soft, coarse, straight-grained, compact, satiny, 

 easily worked ; bands of small summer cells thin, resinous, conspicu- 

 ous, resin passages numerous, very large and conspicuous ; medullary 

 rays numerous, obscure ; colour light brown, the sapwood nearly 

 white ; specific gravity, 0'3684 ; ash, 0*22 ; now largely manufactured 

 into lumber and used for interior finish, door-blinds, sashes, &c, , and 

 for cooperage and woodenware ; less valuable and less easily worked 

 than that of the eastern White Pine (Finns Strohus) ; its quality injured 

 by the larger and more numerous resin passages. A saccharine 

 exudation from the stumps of cut or partially burnt trees is sometimes 

 used as a substitute for sugar (Sargent). 



For the discovery of this gigantic species we are indebted to the 

 late indefatigable collector for the Iloyal Horticultural Society, Mr. 

 David Douglas, who first found it on the western coast of North 

 America. He has given an elaborate description of its growth, 

 &c., in vol. XV. of the " Linnean Transactions," from which the 

 following is an extract : ' ' This plant covers large districts about a 

 hundred miles from the ocean, in latitude 43° N., and extends as 

 far to the south as 40°. It first came under my notice in August 1825 

 while at the head -waters of the Multuomah River. In October 1826 

 it was my good fortune to meet with it beyond a range of mountains 

 running in a south-westerly direction from the Rocky Mountains 

 towards the sea, and terminating at Cape Orford in Vancouver. It 

 grows sparingly upon low hills, and the undulating country east of the 

 range of mountains just mentioned. Where the soil consists entirely 

 of pure sand, in appearance incapable of supporting vegetation, there 

 it attains its greatest size and perfects its fruit in most abundance. 

 The trunk grows from 150 to 200 feet in height, varying from 

 20 to near 60 feet in circumference. One specimen, which had been 

 blown down by the wind (and this was certainl}'' not the largest
