The Schuyler Copper Mine, situated between the 

 rivers Passaick, and Hackinsack, near their con- 

 fluence, in the state of New Jersey, was discovered 

 about the year l!ri9, by Arant Schuyler. The ore 

 was found where it appeared on the side of the hill, 

 was easily raised, and as the policy of England, at 

 that time, prohibited the establishment of smelting 

 works or manufactories in her colonies, it was packed' 

 in casks, each containing about 400 weight, and ex- 

 ported, in its state of ore, to England. It appears 

 by his books, that before the year 1731, Arant Schuy- 

 ler had shipped 6933 casks, making about 1386 tons 

 of raw ore, to the Bristol copper and brass com- 

 pany. 



The ore of the Schuyler's mine yields, in each 

 hundred pound of copper, from four to seven ounces 

 of silver, and like most copper ores, a small portion 

 of gold. At the time when pure copper was sold 

 in England at 75 pounds sterling per ton, the ore of 

 Schuyler's mine was shipped for England at New 

 York, at 70 pounds sterling per ton. This proves the 

 uncommon richness of the ore, and the small expense 

 of converting it into metal. An offer has lately been 

 made by Messrs. Bolton and Watt to purchase all 

 the ore which can be raised, and to enter into con- 

 tract for that purpose.* These facts shew, that a 

 proper knowledge and capital are only ^requisite to 

 work the mines to great advantage. 



Malachite is also found in Wescott's copper mine 

 near Baltimore, in Maryland. At this place, grey
