802 The Trees of Great Britain and Ireland 



Mountains in Washington, and in the east to the mountains of Idaho, Montana 

 (Plate 225), Wyoming, Colorado, and Utah. Everywhere it grows up to or very 

 near the timber line, and on the shores of Lake Bennett in northern British 

 Columbia descends to 2500 feet. In Colorado it reaches 10,000 feet. 



Macoun states that it crosses the Rocky Mountains into the Peace River region, 

 and the country between the Little Slave Lake and the Athabasca River ; and that 

 in the Rocky Mountains of Alberta it occurs with Picea Engeltnanni, but is less 

 common ; and in a letter states that it is an enormous tree at Glacier, but becomes 

 dwarfed at higher elevations, ascending to 7000 feet in that region. 



Wilcox ' writes of it as follows : 



" The balsam fir has about the same range as the white spruce {Picea 

 Engelmanni) but is less common. At a distance it is hardly to be distinguished 

 from the spruce, but the bark on branches and young trees is raised in blisters which 

 contain a drop or two of balsam. This balsam exudes from the bark wherever it is 

 bruised. At first it is a very clear liquid, regarded by old trappers and woodsmen 

 as a certain cure, when brewed with hot water, for colds and throat troubles. On 

 exposure to the air it hardens into a brittle resin, which the woodsman melts into 

 pitch to seal boxes or mend leaky canvas. The camper-out makes his bed from 

 balsam boughs, as they are more springy and less rigid than those of the spruce." 



I saw this tree in perfection in the Paradise valley on the south-west slopes of 

 Mount Rainier in August 1904. An excellent illustration of this locality is given by 

 C. O. Piper in Garden and Forest, vol. iv. p. 382, which shows the tall slender spiry 

 habit of the fir. Here it lives in company with A. amabilis in the lower part of 

 its range, and with Tsuga Pattoniana, and Cupressus nootkatensis higher up ; 

 growing in small clumps and groves, as shown in the illustration referred to. It 

 seems to be a very slow grower, a tree felled by Plummer being only 15 inches 

 in diameter at 125 years old. The tallest that I measured here was yy feet by 

 5 feet 8 inches, but Sargent says that it occasionally attains 175 feet in height 

 (probably in the Olympic Mountains). The seedlings, which I usually found growing 

 on rotten logs, were very slow in growth, and must be often eight to ten years old 

 before their roots reach the soil. 



History and Cultivation 



Abies lasiocarpa was discovered by Douglas in 1832, and his specimen, which 

 is the type of Pinus Jasiocarpa of W. J. Hooker, the first name applied to the 

 species, is preserved in the herbarium at Kew. 



Seeds were first collected about 1 863, by Dr. Parry in Colorado ; but it is not 

 known if any plants raised from these still survive. The first plants raised in the 

 Arnold Arboretum date from 1873, the largest of them being now only 10 to 12 feet 

 in height. Roezl collected seeds in 1874 in Colorado. 2 According to Syme, 8 a small

* Masters, Jourti. Bot. xxvii. 135 (1889), refers these seeds doubtfully to New Mexico ; but there is no doubt that they 

 were collected in Colorado. Cf. Lavallee's article on Nouveattx Conifires dtt Colorado et de la Californie, in Journ. Soc. Cent. 

 Hort. France, 1875. 3 Card. Chron. iii. 586 (1888).
