Blue, Archibald — " The Fourth Report of the Biireau of 

 Mines" 1894, published in Toronto, 1895, distributed May 1896. 

 Contains a large amount of valuable information regarding the 

 mineral production of the Province of Ontario. Gold in Ontaro 

 forms a conspicuous chapter and includes notes on an examina- 

 tion of the northern part of Rainy Lake and Lake of the Woods 

 region. The geological part of the report is prepared by Prof. 

 A. P. Coleman who reviews and utilizes the work done 

 by Lawson and other members of the Canadian Geological 

 Survey. The Lake Nepigon, Lake Temiscaming and Lake 

 Nipissing districts also come in for a share of attention and their 

 mineral resources pointed out. Then follows a chapter on 

 " Acetylene Gas and Calcium." It is with satisfaction that we note 

 what is said regarding diamond drill explorations in Ontario. 

 Care should be taken, however, to preserve the core in every in- 

 stance. "Nickel and its Uses" constitute Section VI of the Reporjt
