been much used. On the Queen Charlotte Islands it is particularly 

 abundant and large. On the Salmon Eiver, running into Dean Inlet, 

 it is not found in abundance beyond eighteen miles from the sea, at an 

 elevation of about 600 feet. It occurs again, however, sparingly, on 

 the lower part of the Iltasyouco Eiver, a tributary of the last, within 

 the Coast Range. On the Homathco Eiver, flowing into Bute Inlet, it 

 ceases at fifty-three miles from the sea, at an elevation of 2,320 feet. 

 On the Uz-tli-hoos (north-east branch of the Anderson, followed by the 

 trail from Boston Bar to Nicola,) it extends to a point six to ten miles 

 east of the Fraser ; on the Coquihalla to the summit between that river 

 and the Coldwater. It is mentioned by Sir A. Mackenzie (Voyages, 

 p. 223) as occurring at the head-waters of the Parsnip (about Lat. 

 54 30'). This is the most northern locality yet known. (Dawson.~)

This tree is found on all parts of Vancouver Island, with the excep- 

 tion of the exposed western coast, but does not occur on the Queen 

 Charlotte Islands or coast archipelago to the north of Vancouver. On 

 the mainland, near the 49th parallel, it extends from the coast to the 

 Rocky Mountains, growing at a height of 6,000 feet in a stunted form. 

 It occurs on the eastern slopes of the Eocky Mountains on the 49th 

 parallel, and is abundant in the foot-hills further north, and on the 

 Porcupine Hills. On the Bow Eiver, it extends east to the vicinity of 

 Calgary. In the dry southern portion of the interior of British Columbia 

 it is generally confined to the higher uplands between the various 

 river valleys, northward it descends to the general level of the country.
