Franklin and Clinton mines. With the sloping of the surface 

 toward the Oriskany valley, the ore beds beyond the Ellingwood 



jpening come out just east of Clinton in a northeast-southwest course 

 at about the 700 foot contour, as shown on the topographic sheet. A 

 iarge quantity of ore has been removed here by open cutting, the 

 excavations extending nearly a mile on the outcrop, with a width 

 of several hundred feet in places. These workings date back man) 

 years. For the last 25 years or more the ore has been mined under- 

 ground. Altogether an area of about 200 acres has been worked 

 over by mining or stripping, and the ore product must amount to 

 nearly 2,000,000 tons. 



The Franklin and Clinton mines are a part of the ore properties 

 owned by the Franklin Iron Manufacturing Co. and have always 

 been operated in connection with the company's furnace at Franklin 

 Springs, 2 miles south of Clinton. They are entered by adit levels 

 that follow the main ore bed in an easterly and southeasterly direc- 

 tion. The advancing long-wall system of mining is employed. 

 From 18 to 24 inches of overlying shale is blasted down with the 

 ore to gain sufficient room for the miners to work. The ore is 

 trammed on cars, holding a little more than a ton, to a loading plat- 

 form near the mine and is then run over a spur to the Ontario & 

 Western Railroad for shipment to the furnace Since the rebuilding
