f^etured into copperas. The establishment is nc\rj and 

 the quantity already manufactured is sufficient to supply 

 the United States. Nei>r the same town a quantity of 

 galena (sulphuret of lead) has been discovered, attached 

 to a brownish substance, which, by the examination of a 

 chymist of thiselty, was found to be the carboijated oxul 

 pf zincor calainine. 



This mineral, with the copper which exists in Ihe 

 same neighbourhpod, will, if found in abundance, prov.e 

 of the greatest utility in the manufacture of Brass. The 

 mines of Perkiomcn, however, furnish both these mate- 

 rials.. 



A peculiar variety of lime-stone, found in Vcrmonf, 

 %vh(ch may be called a chrystalHzed carbonate of lime, 

 and which very much resembles specular gypsum, has 

 been em[)loycd with success in agriculture. It was ge- 

 nerally taken for plaster by tije farmers ; but, on ex- 

 amination, proved iiot to be a sulphate but a carbonate of 

 lime. 



We congratulate every friend of American manufac- 

 tures, who undoubtedly should possess a zeal for so im- 

 portant and so useful an institution, if a spark of patri- 

 otic fire glows in their breasts, that by a uniform perse- 

 verance in the paih already trod, we may be independent
