the Adirondacks and the southeastern Highlands. The hematite 

 amounted to 61,712 long tons, all of it from the Clinton district; 

 while the remainder consisted of a few hundred tons of limonite 

 from Columbia county. The magnetite was made up of 802,241 

 long tons of mill concentrates and 600,618 long tons of lump ore. 

 The concentrates averaged over 60 per cent in iron, the bulk of the 

 shipments carrying 63 to 65 per cent. The lump ore contained 58 

 to 60 per cent iron. In the concentration of magnetite as practised 

 in the Adirondacks, each ton of finished product represents from a 

 little over i to nearly 3 tons of crude ore, the ratio varying with 

 each deposit. Improvements in the, methods of mining and milling 

 have made it possible to handle ore running as low as 25 per cent 

 on a profitable basis. 



The amount of ore hoisted exceeded the shipments by several 

 hundred thousand tons, the difference being accounted for by the 

 shrinkage due to the concentration of the magnetite ores. The 

 actual mine output in 191 7 was a little over 2,000,000 tons, consider- 

 able more than the total for any preceding year.
