The Adirondack Region — Magnetic Iron Ores. 27 



amount of phosphorus makes it a Bessemer ore. An analysis, com- 

 municated by Mr. A. L. Inman, gives the composition as follows: 



Peroxide of Iron 47.38 per cent. 



Protoxide of Iron 21. 32 



Protoxide of Manganese .10 



Alumina 1.97 



Lime _ 1.18 



Magnesia 36 



Phosphoric Acid 08 



Sulphur _.. .02 



Silica. ...27.48 



Metallic Iron .49.74 



Phosphorus 035 



The several mines are connected by narrow gauge tracks with the 

 company's railroad, which runs to the furnaces and the lake at 

 Crown Point. This branch is a 3-foot gauge and, when ore has to 

 be sent over the Del. & Hud. Canal Co.'s road it has to be re-loaded 

 in their cars at the junction. 



The mine equipment consists of large Rand compressors, four 

 winding engines, which operate nine drums, fourteen boilers of 

 about 700-horse-power, and twenty-five pumps. 



The ore is used at Scranton and Bethlehem, Pa., and at Troy, 

 and at the company's furnaces at Crown Point. 



This company owns 32,000 acres of land in a belt, ten miles long, 

 from north to south, in the towns of Ticonderoga, Crown Point, 

 Schroon, and North Hudson, and has several small ore openings out- 

 side of the Hammondville mines proper. North of Hammondville, 

 there is on Moose Mt. an extensive deposit of titanic iron ore, which 

 carries 55 per cent, of metallic iron. It is not worked. 



These mines have been opened and worked for 60 years, but the 

 development has been mostly since 1873.* The total output for the 

 past thirteen years, up to Jan. 1, 1889, is reported by Mr. Inman 

 to amount to 1,041,015 gross tons. 



The officers of the company are, A. L. Inman, Plattsburgh, 

 general manager: H. L. Reed, Crown Point, assistant general man- 

 ager ; and Thomas Montague, Hammondville, superintendent of mines. 



* The Hammond ore bed was known in 1S27, but it was not worked to any extent 

 until 1845. The forge at Irondale was built in 1828. [See Watson's " History of Es- 

 sex County," Albany, 1869, p. 383.]
