LEAD 



Galena, the principal ore of lead, is associated to some extent 

 with the zinc ores in the Edwards district and also with the zinc 

 deposits in the Shawangunk region. A description of the occurrences 

 in these two districts will be found under zinc. Lead alone, or 

 with minor amounts of zinc, was once mined in the western part 

 of St Lawrence county, notably in the towns of Rossie and Macomb, 

 also in the town of Alexandria, Jefferson county; in the town of 

 Ancram, Columbia county; town of Northeast, Dutchess county; 

 and in a few other places. 



At the time of the First Geological Survey of New York State 

 1836-40, much interest was manifested in the deposits in the towns 

 of Rossie and Macomb. A very full account of the lead occurrences 

 and of the mining operations is given in the report by Professor 

 Emmons on the Third District. The Coal Hill and Victoria veins 

 are particularly mentioned by Professor Emmons as having been 

 the basis of rather active exploration in the early days. 



The Coal Hill vein was worked by two companies, the eastern 

 section having been under operation b}^ the Rossie Lead Mining 

 Co. and the western section by the Rossie Galena Co. According 

 to the local records mining at this locality began about 1836 and 

 the output of ore was smelted at a furnace on Indian river, about 

 I mile' distant from the mines. The product of the two companies 

 up to the time they ceased operations was 3,250,690 pounds of 

 metallic lead. The average content of the furnace ore is said to 

 have been 67 per cent. It appears that in 1852 operations were 

 again revived by the Great Northern Lead Co. which employed a 

 number of practical miners from Cornwall, England, and work 

 was extensively prosecuted for about 2 or 3 years. Later the mines 

 and works were leased by J. B. Morgan who operated them for a 

 time. In 1868 the plant was finally closed and has remained idle
