Mica: Its Occurrence, Exploitation, and Uses ; by Hugh S. de 

 Schmid. Pp. xiv, 411 ; 38 plates, 67 figures and 22 maps. This 

 report is a second edition of the earlier one by Fritz Cirkel, issued 

 in 1905 (see vol. xxi, p. 405). The mica production, which had a 

 total value of about $1,800,000 in 1906 and 1907 for the three 

 countries from which the world's supply chiefly comes, fell to 

 less than $600,000 in 1909, and $745,000 in 1910. Of this last 

 amount, $337,000 was the production of the United States, 

 $265,000 of India, and $153,000 by Canada. The two former 

 countries supply chiefly muscovite, while Canada produces 

 chiefly phlogopite, or so-called amber mica. The prominent use 

 of mica at present is in the manufacture of electric machinery ; 

 the possibility, however, of replacing mica plates by sheets of 

 mica board (" micanite ") made of thin broken fragments threatens 

 to further demoralize the market, since it makes possible the use 

 of much cheap material obtained from India. The scientific 

 interest of the present volume is largely in the minute descrip- 

 tion of the many Canadian deposits in Quebec and Ontario, both 

 from the geological standpoint and with respect to associated 

 minerals.
