densely felted shoots, its four-sided leaves and long-pointed cone 

 bracts. 



It is a very local tree which was discovered by Dr. Lyall, 

 surgeon to the British Columbia- Oregon Boundary Commission, 

 1858-1861. Essentially an alpine species, it occupies positions 

 near the timber Une at altitudes of 6,000-7,000 ft. in the Cascade 

 Mountains and on the Galton Range, the largest size being attained 

 in the Whitefish Range. In 1883 it was rediscovered by Mr. T. S. 

 Brandyce, of the Northern Transcontinental Survey. Trees of 

 this species most easily accessible to travellers may be seen 

 above Lake Louise growing among Picea Engelmanni and Abies 

 lasiocarpa within a few miles of the Canadian Pacific Railway. 



The trees grow very slowly, and a section of wood preserved 

 at Kew which is 1\ in. in diameter shows about 130 annual 

 rings, the sapwood being less than \ in. wide and the bark \ in. 

 thick. 



Seedlings have been raised at Kew but have not grown well. 

 A colder country than Britain appears to be necessary for its 

 successful growth. A tree transplanted from the Rockies has 

 lived at Dawyck for several years, the sole survivor of about a 

 dozen Mr. Balfour planted ten years ago ; it is not more than a 

 foot high. Sections of those that succumbed, though not more 

 than 1 or 2 ft. high, showed by their rings that they were at 

 least forty years old.

Larix Marschlinsi, Coaz. 

 The Swiss Hybrid Larch. 



This hybrid larch was raised in the forest garden of Tscharner- 

 holz, near Morat, Switzerland, in 1901. 



The mother-tree was a Japanese larch {L. leptolejiis), and it is 

 thought that the pollen was from the Siberian larch {L. sibirica), 

 although there were trees of L. europcea near by. The seedling 

 trees raised were very vigorous and are now growing at Marsch- 

 linus, Switzerland. By 1917 they had attained a height of 27-33 

 ft., with a girth of 24-26 in. at one foot above the ground. The 

 reciprocal cross is said to have been made in Russia with a view 

 of obtaining a tree less susceptible to disease than L. sibirica.
