Forests and forestry. Ihe Douglas Fir. 337 The Douglas Fie. (Pseudotsuga 1367. This is incomparably the finest of the firs, surpassing them all in size, and equaling the best in value as a timber tree. It extends from Mex- ico, New Mexico, and Colorado, through the mountain regions of the Pacific Coast, occurring in Oregon to the enormous size of 200 to 300 feet in height, and from 15 to 20 feet in diameter. It is more commonly about 150 feet high, and from 4 to 8 feet in diameter. 1368. This tree has a tall pyramidal growth, with horizontal and drooping branches. The bark is rather thin, of an ash or reddish color, and the wood is coarse-grained, but tough and hard. It extends northward into Alaska, and is largely developed in British Colum- bia. Professor Newberry in describing this tree as it grows in Oregon, says: 1369. " The trees stand relatively as near each other, and the trunks are as tall and slender, as the canes in a canebrake. In this case, the foliage is confined to the tuit at the top of the tree, the trunk forming a cylindrical column as straight as an arrow, and almost without branches for two hiindred feet. The amount of timber on an acre of this forest very much exceeds that on a simi- lar area in the tropics or in any part of the world I have ; 1370. The Douglas fir, in British Columbia, forms the principal lumber yet exported from that Province. It forms dark and dense forests of considerable extent, the wood being, for the most part, of excellent quality for ship-building, but varying considerably in strength and texture, according to the conditions under which it ' Commonly described a
