United States Geological Survey, while the figures from 1904 to 

 date have been collected at this office. They represent market-* 

 able ores as shipped to the furnace and not the mine output 

 which is considerably larger, since the greater portion of the 

 magnetite ores is concentrated.

The total shipments reported by the mines in 1907 amounted 

 to 1,018,013 long tons, valued at $3,750,493. As compared with 

 the preceding year when the shipments were 905,367 tons valued 

 at $3,393,609, there was an increase in output of 112,646 tons or 

 about 12 per cent. 



Classified as to variety the shipments consisted of 853,579 tons 

 of magnetite and 164,434 tons of hematite. Of the magnetite 

 499,895 tons were marketed in the form of concentrates with an 

 approximate content of 65 per cent iron. The 353.684 tons of 

 lump magnetite included in the total are estimated to average 

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

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



The 499,895 tons of magnetite concentrates were made from 

 approximately 818,467 tons of crude ore. The mine output or 

 amount of ore hoisted during 1907 was thus 1,336,585 long tons 

 which compares with 1,154,814 long tons in 1906 and 1,109,385 

 long tons in 1905. Based on the crude ore, the output last year 

 was probably as large as that recorded for any previous year in 

 New York State.
