ITALY. LETTER I. 5 



At Feyftriz on the Moor near Pegau, in Steyer- 

 there are fome lead-mines belonging to 

 Baron von HeipeL The mines are the following : 



1 . The Pauls Haupt-Forder and Weather-Shaft. 



2. S. Martins, Haupt-Shaft. 



3. S. Nepomues-Tunnel. 



4. Mary and Melchior Tunnel. 



5. Elifabeth Tunnel -, and 



6. New-Barbara-Schaft. 



They yield, according to what I was told, every 

 year from 4 to 5000 tun of lead-ore, containing 

 from three-quarters of an ounce to one ounce of 

 filver. The ore is a fine cryftalifed galena or 

 glance, found in a vein of quartz and calcareous- 

 fpar, running through a clayifti blue flate-rock, 

 by the higher calcareous and fir-grown mountains. 

 The mines or the fhafts and tunnels are funk in the 

 valley fcarce above the level of the Moor, which 

 river is very near. They are funk in the fame 

 horizontal line in which the limeftone ends, and 

 the inferior flate begins. The Pauls-fhaft is 

 worked down in this flate to a depth of fifty-two 

 fathom. This (haft is drawn and emptied by 

 horfes ; even its water and pump-engine are ma- 

 naged by horfes, till an engine-wheel, which is pre- 

 paring, be ready and fet to work. The fuperior 

 limeftone expofed to day is without any veins, 

 of a compact and found grain, and containing 

 fome petrifactions.
