Habitat.— 'Noxih.QTU. Newfoundland and Labrador to the eastern 

 shores of Hudson Bay, Cape Churchill, and north-west to the northern 

 shores of the Great Bear Lake and the valley of the Mackenzie Biver 

 within the Arctic Circle ; south through the Northern States to Northern 

 Pennsylvania, Northern Indiana and Illinois, and Central Minnesota. 



Introduced in 1739 by Peter Collinson, 



A tree 80-100 feet in height, with a trunk 2-3 feet in diameter ; 

 moist uplands and intervening lands, or south of the boundary of the 

 United States in cold, wet swamps, often covering extensive areas ; 

 here much smaller and less valuable. 



Wood heavy, hard, very strong, rather coarse-grained, compact, 

 durable in contact with the soil ; bands of small summer cells broad, 

 very resinous, dark-coloured, conspicuous, resin passages few, obscure ; 

 medullary rays numerous, hardly distinguishable ; colour light brown, 

 the sapwood nearly white; specific gravity, 0-6236; ash, 0*33; pre- 

 ferred and largely used for the upper knees of vessels, for ship 

 timbers, fence posts, telegraph poles, railway ties, &c. (C. S. Sargent). 



The inner bark of the closely allied European Larch is recom- 

 mended in the treatment of chronic catarrhal affections of the pulmonary 

 and urinary passages ; probably that of the American species would be 

 equally efficacious (C. S. Sargent). 



Larix americana — or, as it is often called, microcarpa — is to be 

 found in Danish gardens about 40 feet high.
