grouse," has not been killed further north than the 

 Nohhane Bute ; the pin-tailed grouse goes as far 

 down as the delta ; and the Tetrao canadensis lives 

 in the marshy parts of the forest up to Peel's 

 River, and is named Ti ; while the willow and 

 white-tailed ptarmigans bear the designation of 

 Kasbah or Kampbah, in the Slave or Chepewyan 

 tongue. The last named is exclusively an Alpine 

 species. The American magpie has not been seen 

 to the north of the River of the Mountains, and is 

 rare even there. 



Many large streams join the Mackenzie below 

 Fort Simpson. One, which the Nohhane Indians 

 are accustomed to descend, flows down the valley 

 between the first and second mountain ridges, and 

 joins the Mackenzie at its great bend. It is desig- 

 nated from these people, but it must not be con- 

 founded with the stream of the same name, which 

 issues also from the hunting-grounds of the Noh- 

 hanes, but falls into the River of the Mountains. 



The Willow Lake River enters the Mackenzie a 

 little below the bend, from the right bank. It is 

 ascended by the Marten Lake Indians as far as it 

 is navigable for their canoes, and then a march of 

 four hours, or of from ten to fifteen miles, takes 

 them to Marten Lake. 



Another river of considerable size comes in on 

 the left bank, which is named the Bekka-tess by
