When they reached the Cascades, an examination was made of the 

 pine stumps before spoken of. 



The same evening a boat reached the salmon-fishery, by which 

 Mr. Drayton returned to Vancouver, where he met with the same 

 kind reception and welcome he had before received. 



From this trip Mr. Drayton brought with him the materials for 

 the construction of a map of the river, above the Cascades as far as 

 Wallawalla, which has been incorporated in our chart of Oregon, and 

 will be found in the small atlas accompanying the Narrative. I take 

 this occasion to say, that I have embraced within this the whole of the 

 territory of Oregon between the parallels of 42° and 54° N. The 

 southern pass of the Rocky Mountains is also included, which was 

 taken from the surveys of Lieutenant Fremont, of the United States 

 Engineer Corps, and which I have designated as Fremont's Pass. 

 This officer is now engaged in an exploration of the country about 

 the Youta Lake and the middle section of the territory, in a line on 

 the east of the Cascade Range, from John Day's river to the south, — 

 a portion of the country it was my intention to have traversed, if the 

 Peacock had reached the Columbia river at the appointed time.
