of balsam. The Indians recognize them as different from the 

 Spruce, although they have no separate name for them. 



The Gray or Jack Pine Pinus divaricata — {Con of the Dog-ribs), 

 Tamarack {Larix americana — Dog-rib name Inne doui), and 

 Poplar I did not find north of Aiejean Ti, Willows occurred as 

 dwarf trees sparsely all over the barrens, extending far beyond 

 the Spruce. Canoe Birch, Betula papyrifera — (Dog-rib name Ki) 

 was found north of Aiejean Ti only as a dwarf tree. 



The following notes on the birds were made during the hunting 

 trip above described. I kept no record of the Raven nor of the 

 Canada Jay. I have also omitted most of my observations on 

 the birds of Great Slave Lake because that country is so well 

 known that the rough data I was able to obtain seemed to me 

 valueless. On the other hand Aiejean Ti, Diri Ti and Conghia Ti 

 have never been visited by any white man but myself. Jjamba 

 Ti was visited l)y Prof. Russell in 1894 early in the spring before 

 the arrival of migrants. Therefore it seemed to me that that part 

 of the country was so little known that any information about its 

 birds might be worth preservation.
