subordinate gangue mineral in certain silver veins of that region, 

 which intersect metamorphic and igneous rocks, and has been actively 

 worked ever since the discovery of radium by M. and Mme. Curie 

 in 1898. Before that time the mineral had a certain value as a 

 source of uranium compounds. 



These Austrian mines are second to those of the United States 

 as a source of radium and uranium, but their production equals 

 only a very small part of that of this country. Until the present 

 war began this production was controlled largely, if not wholly, 

 by the Austrian Government, and as the production is said still 

 to continue, it is probably still controlled in the same way. 



Cornwall, England. Next in importance in Europe to the uran- 

 inite or pitchblende ore of Joachimsthal as a source of radium and 

 uranium, is the similar ore in some of the mines of Cornwall, Eng- 

 land. 1 It occurs as a subordinate mineral in the gangue of some 

 of the old tin. and copper mines in veins intersecting metamorphic 

 and igneous rocks, especially at St Just, St Ives, Grampound Road, 

 St Austell and elsewhere. The production and treatment of the 

 ore has been under private or corporate auspices and the amount 

 produced has not been large. 



Germany. In Germany the production of radium and uranium 

 ores has always been insignificant. A small quantity of such ores 

 has been produced at Schneeberg, Johanngeorgenstadt, Annaberg 

 and elsewhere. Before the war, Germany was a large producer of 

 manufactured radium and uranium compounds, but they were 

 derived mostly from imported American ores. 



Other localities. With the exception of Joachimsthal and Corn- 

 wall, Europe has produced but small quantities of radium and 

 uranium minerals. A little uraninite or pitchblende has been 

 found in other localities in Austria, such as Przibram and else- 

 where, and sparingly in Norway. Autunite and other uranium 

 minerals have been found in small quantities near Autun, France, 

 and near Sabugal and Guarda, in Portugal, but no important quan- 

 tities have been produced.

 other rare uranium minerals occur in regions of metamorphic and
