CANADIAN MINERAL STATISTICS.^ 

 'T*HE report before us contains a number of .short 

 articles on various points of special interest to those 

 engaged in mining operations in Canada, and should prove 

 of decided value to them, though it must be admitted 

 that in the majority of cases the interest is mainly local. 

 A short note refers to accidents in Canadian mines caused 

 by explosives, and shows that the high accident death-rate 

 is due to the absence of protective legislation in Canada. 

 The following is given as the death-rate per 1000 miners 

 in various parts of Canada : — 



per lox) 

 British Columbia, Coal Mines, 1899-1908 ... 921 



Nova Scotia, Coal Mines, 1899-1908 267 



British Columbia, Metal Mines, 1908 593 



Ontario, Copper and Nickel Mines, 1907 ... 2-19 

 Ontario, Silver and Iron Mines, 1907 7-36 



These figures afford convincing evidence of the need of 

 a complete mining code, properly administered, seeing that 

 there is nothing in the mining conditions of Canada to 

 which so formidable a death-rate can fairly be ascribed.
