FOREIGN MINING REGIONS. 405 



14. Iii Hcssc-Cassel to the southwest of the Hartz, at 

 Riechelsdorf. Ores. Arsenical cobalt, arsenical nickel, 

 nickel ocher, native bismuth, bismuth glance, galena, af- 

 fording cobalt. Rock: Red sandstone. Also at Bieber, 

 cobalt ores in mica slate. 



15. In the Bavarian or Upper Rhine, (Palatinate,) near 

 latitude 49° 45', at Landsberg near Moschel, Wolfstein, and 

 Morsfeld. Ores. Cinnabar, native mercury, amalgam, horn 

 quicksilver, pyrites, brown iron ore, some gray copper ore, 

 and copper pyrites. Rocks. Coal formation. 



16. Province of the Lower Rhine, at Altenberg, near 

 Aix la Chapelle (or Aachen.) Ores, Calamine, electric 

 calamine, galena, affording zinc. Rock. Limestone. The 

 same, just south in Netherlands, at Limburg, and also to the 

 west at Vedrin, near Namur. 



17. There are also copper mines at Saalfeld, west of Sax- 

 ony, in Saxon-Meiningen, in Southern Westphalia near 

 Siegen, in Nassau at Dillenberg, and elsewhere. 



18. In Switzerland, Canton du Valais. Ores. Argentif- 

 erous lead, and valuable nickel and cobalt ores. 



19. The range of the Vosges, in France, parallel with 

 the Rhine, about St. Marie-aux-Mines. Ores. Argentifer- 

 ous galena, (affording 1-1000 of silver,) with phosphate of 

 lead, gray copper, antimonial sulphuret of silver, native sil- 

 ver, arsenical cobalt, native arsenic, and pyrites, occasion- 

 ally auriferous ; affording silver and lead. Rocks. Argil- 

 laceous schist, syenite, and porphyry. 



20. In France there are also the mining districts of the 

 Alps, Auvergne or the Plateau of Central France, Brit- 

 tany, and the Pyrenees, but none are very productive, ex- 

 cept in iron ores. Brittany resembles Cornwall, and for- 

 merly yielded some tin and copper. The valley of Oisans 

 in the Alps, at Allemont, contains argentiferous galena, 

 arsenical cobalt and nickel, gray copper, native mercury, and 

 other ores, in talcose, micaceous, and syenitic schists, but 

 they are not now 7 explored. The region of Central France 

 is worked at this time only at Pont-Gibaud, in the department 

 of Puy-de-Dome, and at Vialas and Villefort in the Gard. 

 The former is a region of schistose and granite rocks, inter- 

 sected by porphyry, affording some copper, antimony, lead, and 

 silver ; the latter of gneiss, affording lead and silver from 



rgentiferous galena. The French Pyrenees are worked at 

 he present time only for iron.
