Dr. C. T. Jackson gave an account of some minerals

100,000 



This is a rich ore, and worth $1 90 per cubic foot. 



In the same town was found an ore of antimony and copper 

 without silver. In Warren there exists, in a bed of Tremolite, an 

 ore of copper containing 20 per cent, of metal, and very abundant.
