 tion ; common along the eastern slopes of the Rocky Mountains of

A tree growing 50 feet high, with a compact head, found in great 

 abundance, forming large forests on the northern side of the snowy 

 range of mountains in Kunamur, beyond the influence of the periodi-

 exceeding 50 feet in height, furnished with numerous horizontal 

 branches nearly to the ground, the upper ones forming a large, 

 compact, conical head. It is also found to the north of Cashmere, 

 and on the Astor Mountains in Little Thibet. The mountains near
