LEADVILLE SILVER-BEARING DEPOSITS. 79 



to the ton, and perhaps contain gold as well. Several mines 

 in Western America from which silver and gold used to 

 be worked, are still worked chiefly for the gold rather than 

 for the silver and gold. 



As suggested before, the remembrance of chloride of 

 silver and carbonate of lead (carrying silver), both of which 

 occur in many silver-bearing lode districts, should retain 

 a corner in the thoughts of the prospector, who, whenever 

 he has the opportunity, should thoroughly examine, and 

 even experiment upon, pieces of these so very easily passed 

 by minerals. Considering that a pure piece of chloride of 

 silver, sometimes found in lumps in New South Wales, 

 Chili, &c., contains 75 per cent, of the metal, it is easily 

 understood how valuable a deposit of the same may prove. 

 The carbonate of lead, too (with silver), most unlikely by 

 outward appearance to suggest value, often contains much 

 of the valuable metal.
