          that would be of benefit to us respecting the Pyrites?


 We found a range of mountains that were a
 solid mass of flint, running through them we traced for
 several miles a vein of red and green Talcose slate about
 14 feet wide as handsome as any you ever saw we have assayed
 it & found copper. Do you think we would find a load of 
 copper by sinking a shaft? We are residents of New
 Orleans on our way home, shall remain but a short time before
 we return. If you feel disposed to answer this we would
 request an early reply, as we desire to get all the information
 we can before returning.


 Yours respectfully

 Is silver ever found in Pyrites?
 Enclosed you will find
 a small piece of clay. I wish you
 would dissolve it with Chloride
 of lime, precipitated with copper or water
 & inform us what the sediment is
