raised from the mines during the year was 1,074,175 tons; and the 

 total quantity of ore of all kinds taken out was 1,122,221 tons. In 

 1914 the gross output amounted to 1,606,196 tons. 



The list of the active mining companies for the year included the 

 following in the Adirondack region : Witherbee, Sherman & Co., 

 and Port Henry Iron Ore Co., Mineville ; Cheever Iron Ore Co., 

 Port Henry ; Chateaugay Ore & Iron Co., Lyon Mountain ; Benson 

 Mines Co., Benson Mines. In southeastern New York the pro- 

 ducers were the Hudson Iron Co., Fort Montgomery, and Sterling 

 Iron & Railway Co., Lakeville. The hematite mines were operated 

 by C. H. Borst, Clinton; Furnaceville Iron Co., Ontario Center; 

 and Ontario Iron Co., Ontario Center. The single limonite mine 

 was operated by Barnum Richardson & Co., who shipped the out- 

 put to their furnaces in Connecticut. 



Mineville. The two Mineville companies supplied a little over 

 one-half of the total product of furnace ore, but their output was 

 considerably below that reported for 1913. Operations in the latter 

 part of the year were hampered by the loss of milling capacity due 

 to the burning of the two older mills, No. 1 and No. 2, on the 

 Joker-Bonanza properties of Witherbee, Sherman & Co. This left 

 only No. 3 and No. 4 mills on the Harmony and Barton Hill mines 

 to handle the output. Construction work was immediately started 

 upon a new magnetic concentration plant which will have a capacity 

 equal to that of the mills that were destroyed, and which will treat 

 the high-phosphorus ores of the Old Bed mine group. 



The mines under active operation during the year included the 

 Joker-Bonanza, Harmony and Barton Hill groups of Witherbee, 

 Sherman & Co., and 21 and Clonan shafts of the Port Henry Iron 

 Ore Co. In the Joker-Bonanza territory attention was directed 

 mainly to the flat seam which underlies the main ore body and 

 resulted in the further extension of the productive ground. 



Lake Sanford. The most important recent development in con- 

 nection with the titaniferous magnetites of this locality has been 

 the experimentation in smelting the ores on a practical scale, for 

 which purpose the Maclntyre Iron Co. secured a lease of the Port 

 Henry blast furnace for a part of the past year and conducted a 

 series of tests in the production of pig iron with varying portions 

 of Lake Sanford magnetite in the charge. The interest and value 

 of the tests are more than local, as they seem to have demonstrated 

 the commercial utility of the great bodies of ore which the com- 

 pany owns in the Adirondacks and which doubtless it will under- 

 take to bring into market.
