In the Mines Branch, special papers have been published on 

 the production of coal, iron, cement, and other products, for 

 1909 ; another on peat bogs and the peat industry, etc. A pre- 

 liminary report by John McLeish (pp. 21) has also been issued 

 giving a summary of production for 1910. The total value of all 

 products amounts to 105 million dollars contrasted with 92 

 millions for 1904, an increase of over 14 per cent, which gain is 

 distributed throughout the whole list. The value of the gold 

 produced was upwards of 10 millions, of silver 13 millions, of 

 nickel and pig iron each 1 1 millions, and copper 7 millions. 

 Among the non-metallic minerals, it may be noticed that the pro- 

 duction of coal was nearly 30 millions and of asbestos 2^ millions. 

 The last subject is treated at length in a special volume by Fritz 

 Cirkel entitled : 



Chrysotile— Asbestos : its occurrence, exploitation, milling, and 

 uses; pp. 316, 66 plates, 88 figures. This is the second edition 

 of a work first issued in 1895 (see vol. xxi, p. 255). The import- 

 ance of the subject can be appreciated from the fact that 82 per 

 cent of the world's supply of asbestos is now produced by Can- 

 ada, while the value of the product has increased from $24,700, 

 in 1880, to the total already noted above. The author notes 

 further that at the Black Lake quarries, Quebec, there are some 

 45 million tons of asbestos rock now in sight. The subject is 

 treated in its various aspects with admirable fullness, and is 

 illustrated by a large number of excellent plates. 



5. Mineral Production in the United States in 1909.— The divi- 

 sion of Mineral Resources, United States Geological Survey, in 

 charge of E. W. Parker, has issued in rapid succession the indi- 

 vidual chapters which will present!}' appear in the complete volume 

 Mineral Resources for 1909. A comprehensive sheet has also 

 been distributed, giving the quantity and value of each of the 

 mineral products for the calendar years 1900-1909. The grand 

 total valuation amounts to nearly 1900 million dollars, which has 

 been exceeded only in the years 1906 and 1907. In 1900 the 

 total value was only a little in excess of 1100 millions, while in
