The total shipments reported by the mines in 1906 amoimted to 

 905,367 long tons valued at $3,393,609. Compared with the pre- 

 vious year this was an increase of 78,318 tons or about 9 per cent. 

 The production was more than double that reported for 1901 and 

 was the largest for any year since 1891. 



Classified as to variety the shipments consisted of 717,365 tons 

 of magnetite, 187,002 tons of hematite and 1000 tons of limonite. 

 Of the magnetite 479,644 tons were marketed in the form of con- 

 centrates with an approximate content of 65 per cent iron. The 

 237,721 tons of lump magnetite included in the total are estimated 

 to average 60 per cent. The hematite and limonite range from 40 

 to 60 per cent, with an average probably of 45 per cent. 



The magnetite concentrates were made from 729,091 tons of 

 crude ore. Using that figure for a basis of calculation, the total 

 quantity of ore hoisted from New York mines in 1906 was 1,154,814 

 long tons. In 1905 the quantity was 1,109,385 long tons. 



The magnetite was derived mainly from the Adirondack region. 

 The producers included Witherbee, Sherman & Co. and the Port 

 Henry Iron Ore Co. at Mineville ; the Arnold Mining Co. at Arnold ; 

 and the Chateaugay Ore & Iron Co. at Lyon Mountain. The Salis- 

 bury Steel & Iron Co. made a small output in connection with the 

 development of their mine at Salisbury. In southeastern New York 

 the Hudson Iron Co., which took over the Forest of Dean mine In 

 1905, began shipments. It has been the only producer In that section. 



Of the total quantity of hematite reported the mines In the Clinton 

 formation contributed a little more than half. The Franklin Iron 

 Manufacturing Co. and C. A. Borst at Clinton and the Furnaceville 

 Iron Co. at Ontario operated the mines. The remainder of the 

 hematite came from St Lawrence and Jeflferson counties where the 

 Rossle Iron Ore Co. and the Old Sterling Iron Co. were active. 



The single producer of limonite was the Amenia Co. at Amenia, 

 Dutchess CO. 



The Fair Haven Iron Ore Co. was engaged In developing Its prop- 

 erties near Sterling Station, Cayuga co., but produced only small 

 quantities for trial purposes. It will begin commercial shipments 

 this year. 



In the Adirondack region, the exploration of the titanlferous 

 magnetites near Lake Sanford, Essex co., has attracted much atten- 

 tion. It has been known for many years that the ore bodies are of 

 enormous extent, and the recent tests have confirmed and added to 

 the previous estimates. The successful Issue of the enterprise must 

 depend of course upon the metallurgical factor, which has hitherto
