The production in 191 1 as reported by all the active mines was 

 952,364 long tons valued at $3,184,057. Compared with the 

 reported output of 1,159,067 long tons for 1910 there was a decline 

 of 206,703 tons or about 18 per cent. The average value was $3.34 

 a ton against $3.37 a ton in the preceding year; but the decline in 

 the market prices was greater than indicated by this comparison 

 since the average grade of the ore as shipped was considerably 

 higher in 191 1 than in 1910. 



Of the output magnetite constituted a total of 909,359 long tons 

 and represented a value of $3,088,869. The quantity of hematite 

 mined was 38,005 long tons, all from the Clinton belt, with a value 

 of $88,188. A few thousand tons of limonite were shipped from 

 the Dutchess county district. No carbonate ore was produced. 



The output of magnetite was made up largely of concentrates and 

 consequently did not represent the full quantity of that ore hoisted 

 from the mines. The actual mine output of magnetite was 1,215,868 | 

 tons. The total quantity of ore of all kinds hoisted during the year 

 therefore was 1,258,873 tons. In 1910 the corresponding total was 

 1,517,880 tons. 



The list of companies that were active in the industry last year 

 included for the Adirondack region : Witherbee, vSherman & Co. 

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

 Ore Co., Port Henry; the Chateaugay Ore and Iron Co., Lyon 

 Mountain; and the Salisbury Steel and Iron Co., Sahsbury Center. 

 The Benson Mining Co., at Benson Mines, was engaged in erecting 

 a new mill but did not contribute any output last year. The pro- ! 

 ducers of magnetite in southeastern New York were the Hudson 

 Iron Co., Fort Montgomery, and the Sterling Iron and Railway Co., ' 

 Lakeville. The single producer of limonite in the region east of the 

 Hudson river was the Amenia mine. The output of hematite was 

 made by C. A. Borst, Clinton ; Furnaceville Iron Co., Ontario 

 Center; and Ontario Iron Ore Co., Ontario Center. 



Mineville. The two companies at Mineville maintained steady 

 operations throughout the year, though on a somewhat reduced 

 scale as compared with their output in 1910. The amount of ore 

 hoisted was reported as 734,353 tons, against 953,553 tons in the 

 preceding year, which was the largest on record. 



The mines operated by Witherbee, Sherman & Co. included the 

 Old Bed, Harmony and Barton Hill groups. Both lump ore and 

 concentrates were shipped, the concentrates being supplied from No. 

 I and No. 2 mills on the Old Bed and No. 3 mill on the Harmony 

 group. The lump ore came from the Old Bed.
