Tin was not known to exist in France until 1809, and it was not until 1817 that 

 a deposit was discovered. This was found by a marine officer, and Dufrfinoy was 

 sent to examine it. The tin ore occurs at the junction of granite and. slate and 

 the country bears a marked resemblance to Cornwall.

Deposits of tin at Montebras are at contact of granite and feldspathic porphyry. 

 Ore said to average 4 per cent, which would be above the grade of other European 

 deposits.

Small veins carrying cassiterite are known to occur near Vaulry and have been

 et Cieux, secured a concession of alluvial ground near by, and some ore is 

 being produced. 



496. . The mines of Montebras.

Treats of the situation and size of the concession; history of the discovery of the

 States that pyrite, mispickel, sphalerite, galena, quartz, emerald, muscovite and 

 plogopite micas, gilbertite, tourmaline, topaz and feldspar are found with the

 space is given to a description of the working of the mine, its machinery, etc.
