3$ TRAVELS THROUGH 



are found between the Date and the calcareous 

 rocks, where they border upon, and fkirt or fepara^e, 

 one another. That is the cafe with the large vein of 

 copper-pyrites at Agorth, in the Bellunefe in Valle 

 Imperina, where the Tyrol-flate dips under the 

 Venetian Alps. Thefe dgortb-mmes yield every 

 year large quantities of copper, fulphur, and vi- 

 triol. They fave in a vitriol-manufactory a good 

 deal of cemented or precipitated copper, by put- 

 ting iron into the boiling pans. Purfuing the 

 limits and borderings of the flate and the lime- 

 done hills along the chain of the Alps, you will 

 meet, in the reparation, of the primitive flate and 

 the calcareous hills, with different metallic veins 

 and mines. For example, going from the Valk 

 Imperina to the weft, you find within fix Italian 

 miles of thole rock-limits at Feltrino nelld Valle 

 delle Monacbs, the mercury and cinnabar mines, 

 which for many years have been worked by the 

 Magijlrato delle Miniere, but now are deferted. 

 Jn the fame valley you meet with old bings 

 and marks of other metallic mines. The chief 

 vein at Scbio in Monte Narro runs between 

 the flate, which is its hading fide (das Lisgende) 

 and between the limeftone, which is its hanging 

 fjde (das Hangende). It yields lead -ore, copper- 

 pyrites, black jack (blende), white calamine, mun- 

 dicker marcafites, and manganefe or brown- ftone
