Habitat. — Nootka Sound, Sitka, Yancouver, south along the islands 

 and coast ranges of British Columbia, and the Cascade Mountains 

 between 44° and 55° N. ; Washington Territory and Oregon to the valley 

 of the Santian River, Oregon (" Lucky Camp Mountain," Cusick). 



A large tree of great economic value, 100-125 feet in height, with 

 a trunk 4-6 feet in diameter, or toward its southern limits and at 

 high elevations much smaller ; common along the coast at the sea- 

 level to about latitude 49° 30' N., then less common and only at 

 higher elevations ; south of British Columbia hardly below 5,000 feet 

 elevation, and very rare and local. The most valuable timber tree of 

 Alaska. 



Wood light, hard, not strong, brittle, very close-grained, compact, 

 very durable in contact with the soil, easily worked, satiny, susceptible 

 of a beautiful polish, possessing an agreeable resinous odour ; bands 

 of small summer cells thin, not conspicuous ; medullary rays thin, 

 numerous, hardly distinguishable ; colour bright, light clear yellow, 

 the thin sapwood nearly white; specific gravity, 0*4782 ; ash, 0'34 ; 

 somewhat used in boat and ship building, for furniture, interior finish, 

 &c. ; probably unsurpassed in beauty as a cabinet wood by that of any 

 North American tree (Ch. S. Sargent). 



Mr. Menzies was the first discoverer of this species. He obtained 

 specimens from Nootka Sound, when Yancouver (with whom he sailed 

 as surgeon and naturalist) stopped there in his celebrated voyage 

 round the world ; and from his specimens Lambert described it in his 

 "Genus Pinus." It was introduced from the Botanic Garden of 

 St. Petersburg into Europe, under the name of Thuyopsis horealis^ 

 about 1850, and is now plentifully distributed. 



Mr. R. Brown, who collected for the Edinburgh "British Columbia 

 Botanical Association," in one of his letters incidentally notices one or
