this ore there are apparently many millions of tons, and in character it 

 is, so far as I know, without parallel among all the ore deposits of the 

 country. At a distance of half a mile, the limestones are cut through 

 by a great dyke of diorite, which has doubtless furnished the heat that 

 was the mainspring of the chemical affinities, but it has apparently 

 contributed nothing to the mineral matter of the ore deposit. At a 

 point further south, the dyke crosses the zone of limestone which holds 

 the ore. It is there metamorphosed, but not at all minerahzed. 



In the same region are other mineral deposits, which will probably 

 prove to be of considerable value. Among these is another series of 

 chambers in limestone, filled with hard carbonate of lead and galena. 

 Others still, which are rich in copper, also carry silver and gold.
