IRON ORES OF THE CLINTON FORMATION IN 

 NEW YORK STATE 



BY 



D. H. NEWLAND 



AND 



C. A. HARTNAGEL 



INTRODUCTION 



The hematites accompanying the belt of Clinton strata in New 

 York State have been worked commercially, though with some inter- 

 ruptions, since the early part of the last century. It is on record 

 that a mining lease was granted in Oneida county as far back as 

 1797, and a small quantity of ore was shipped from Wayne county 

 during the War of 1812. Regular mining operations were not 

 instituted, probably, until about 1825. A few years later charcoal 

 forges and furnaces had been erected in Wayne, Madison and 

 Oneida counties, as reported by the geologists connected with the 

 Natural History Survey of the State. 



The production of Clinton ores has averaged about 75,000 tons 

 for the last few years. In 1907 it was 109,025 tons. The aggregate 

 from the beginning may be placed at from 4,000.000 to 5,000,000 

 tons, which is approximately the yield obtainable, with the average 

 workable seam, from a square mile of area. Mining has been 

 restricted entirely to the surface portion of the bed_s, and little or 

 nothing has been done by the mine interests, hitherto, toward 

 exploration outside the limited fields of operations.
