Report of the Expedition in the Yukon District, N. W. T., anb 



Adjacent Northern Portion of British Columbia. — By Dr. 



G. M. Dawson, 1887. 



The above report whicli is upon a portion of the work of the 

 Yukon Expedition of 1887-88, by Dr. G, M. Dawson, forming Part B. 

 of the Annual Report of the Geological Survey, (1887) has just been 

 distributed. In this report Dr. Dawson details the results of that 

 part of the exploration carried out by himself, adding thereto some 

 portions of Mr. McConnell's work during 1887, which belong to the 

 same general region. Further reports, dealing particularly with the 

 country to the North and East of that covered by this publication, are 

 stated to be in course of preparation by Mr. R. G. IVlcConnell and Mr. 

 W. Ogilvie. 



The present report is a book of 277 pages, and is accompanied by 

 an index map, while a detailed map with Geological indications, in 

 three sheets, including the Strikine, Dease, Upper Liard, Frances, 

 Pelly, and Lewes Rivers, with adjacent country, is promised in the 

 course of a few days, under separate cover. 



A comparison of the index map, with previous maps professing to- 

 represent the same regions, coupled with Dr. Dawson's well-known 

 accuracy, shows what an important contribution this report is to our 

 knowledge of the Geography of North Western Canada. The first 

 part of the report is of a general character, and in this the ruling 

 physical and geological features are described, and some facts given 

 respecting the climate, flora, fauna, and resources of the country as a 

 whole. In the following part the country examined is taken up by 

 districts, and greater detail is entered into. Historical notes are also 

 added, for each district, of the exploits of the few earlier explorers, who 

 originally penetrated this country in the interests of the Hudson Bay 

 Company, or for^other objects. 



The report includes seven appendices, of which the first is on the 

 distribution of trees, the second on the Indian tribes of the regions, the 

 third a list, by Professor Macoun, of the plants collected (201 species, 

 of which three are new.) The fourth appendix is zoological, including
