Abundant and large in the Kootanie-Columbia valley, and in the

 valleys. To the west of these ranges, sparingly, about Great Shu- 

 swap Lake; also, in the Coldstream valley, near the head of Okinagan 

 Lake. The summit between Osoyoos Lake and the Kettle Eiver was 

 named Larch-tree Hill by the boundary commission expedition, this 

 being the first place at which the tree was found abundantly in travel-
