The Adirondack Region — Magnetic Iron Ores. 25 



reached is 132 feet; the opening on the ore bed is about 100 feet, 

 and the average thickness of the ore in the mine is sixteen feet. The 

 walls are not, however, well denned. The ore is rich, analyses 

 showing 54 per cent, of metallic iron and little sulphur. It is rather 

 fine-crystalline, and has a tendency to a prismatic structure. Pyrite 

 occurs in scattering, nodular masses, particularly near the walls. 

 The ore is carted to Ticonderosra and Crown Point. A Bleichert 

 tramway is proposed, to run direct to the railroad and lake shore 

 from the mine, which is about 300 feet higher than the lake. The 

 plant consists of one Copeland & Bacon hoisting engine, one air 

 compressor, three steam pumps, power drills, etc. B. W. Burleigh, 

 of Ticonderoga is the manager. 



MT. DEFIANCE ORE BED, Ticonderoga, Essex County.— 

 Hematite occurs at the foot of Mt. Defiance, and about 50 rods 

 from the shore of Lake Champlain. The vein is eight feet wide, and 

 dips at a high angle south-west. A pit 50 feet deep has been sunk, 

 and some ore has been shipped to Port Henry and to Chatham. 

 The place was opened in 1888 by B. W. Burleigh, of Ticon- 

 deroga. 



PARADOX LAKE MINE, HARRIS MINE, Schroon, Essex 

 County. — These mines were first opened many years ago, and were 

 worked a few months during 1879-80, since which time they have 

 been idle. The first named is on the south side of Paradox Lake ; 

 and the other on the north-west of the same water. Their production 

 has not been more than a few hundred tons. 



SKIFF MINE, Crown Point, Essex County. — The Horicon Iron 

 Company, and later, its successor, the Lake Champlain Ore and 

 Transportation Company, have done some work at the Skiff mine. 

 It is situated on a hillside, two miles southerly from Hammondville. 

 The same company owns the Schofielcl mine, an old opening in the 

 town of Schroon, one-third of a mile south of the Paradox mine. 



All of these mines have been idle since 1880. 



CROWN POINT MINES, Crown Point, Essex County.— The 

 group of mines belonging to the Crown Point Iron Company 

 is in the western part of the town of Crown Point, and thirteen
