774 The Trees of Great Britain and Ireland 



Distribution 



On the north-west coast of America this magnificent tree has a wide range, 

 from Vancouver Island, where it grows at low levels and is not, so far as I saw, a 

 conspicuous feature in the forest ; through Washington and Oregon as far south as 

 Mendocino County in California, where it does not extend far from the coast, and 

 grows in company with Sequoia sempervirens and Picea sitchensis. 



Inland it is less abundant on the eastern slopes of the Cascade Mountains, but 

 extends to the Cceur d'Alene and Bitter-root Mountains of Idaho and Montana 

 In the Flathead Lake Country it is a comparatively small tree, attaining only 

 12 to 15 inches in diameter, and ascending to about 3500 feet. 



It reaches its maximum development in a damp climate and in sheltered valleys, 

 where I have measured trees much over 200 feet in height, and where, according to 

 Sargent and Sheldon, it sometimes reaches as much as 300 feet. So far as I saw, 

 and Sargent confirms this observation, it never grows gregariously, but scattered 

 among other species ; and rarely forms an important element in the timber. 



It is easy to recognise when young by the flat arrangement of the leaves, 

 but when its branches are far above one's head I could not distinguish it from 

 A. amabilis in the Cascade mountains, or from A. Lowiana which seems to take its 

 place in southern Oregon and northern California. 



It grows very fast in its own country, a specimen measured at 2500 feet altitude 

 on the Cascade Mountains being 140 feet by 16 feet on the stump, at only 106 years 

 old. Though the timber is not much valued by lumbermen, it is used for various 

 purposes locally, and, according to Sheldon, makes the most durable shakes a name 

 used for large shingles cleft with the axe used in Oregon. 



The tree figured (Plate 218) was growing in 1904 on Swallowfield farm, about 

 fifty miles north of Victoria, in Vancouver Island, and when 1 measured it, was 

 215 feet by 19 feet. 



Abies grandis was discovered on the Columbia river by Douglas in 1825, 

 though he does not seem to have sent seeds to the Horticultural Society until 1831 

 or 1832. Very few of these germinated, and it is doubtful if any of the original 

 seedlings are still living. 1 The next consignment * of seed was sent by William Lobb 

 in 185 1 to Messrs. Veitch at Exeter; and about the same time seeds were received 

 by the Scottish Oregon Association from their collector Jeffrey. 



Remarkable Trees 



There are many fine trees of this species in the warmer and moister parts of 

 England, Scotland, and Ireland ; and, with A. nobilis and A. Lowiana, it seems 

 best suited of all the American firs to our climate. 3 



1 Murray, Proc. Roy. Hart. Soc. 31 1 (1863), states that there were then living no authentic seedling specimens of A. grandis 

 raised from the seeds sent by Douglas, but a multitude of young plants existed which had been raised from cuttings.
