The Adirondack Region — Magnetic Iron Ores. 43 



1881, and their output up to January 1. 1889 — a period of 7 years 

 and 8 months — amounted to 1,519,520 cross tons. 



MINE 81, Belmont, Franklin County.— The openings on lot No. 

 81, are one mile north-east of Standish. The ore bed here oecnrs 

 with a dip of 70° to 75° to south-east. The wall rocks are a coarse- 

 crystalline, syenitic gneiss. The ore was ^vorked in the deepest shaft 

 to a depth of 130 feet. It was carted by teams to separating works 

 and furnace at Standish. The mine has been idle four years. This 

 mine also belongs to the Chateaugay Ore and Iron Company. 



In Franklin county magnetic iron ore has been mined at two 

 localities in the town of Duane and in Malone, but for many years 

 the miues have been abandoned.* These mines are too far from 

 transportation lines to be of importance at present prices for ores. 



CLIFTON MINES, St. Lawrence County.— Extensive beds of 

 magnetic iron ore were opened about forty years ago on Grasse 

 river, 20 miles south-east of De Kalb Junction, by the Clifton Mining 

 Company, and costly preparations made to do a large business. A 

 charcoal furnace on Grasse river near the mines, was run for a time 

 on these ores exclusively. f The ore is reported to contain some 

 titanium. 



JAYVILLE MINES, Fine, St. Lawrence County. — The exis- 

 tence of iron ore at this locality was known at least 20 years 

 ago, and some mining was done before the present company took 

 possession. In 1886 the Carthage and Adirondack railroad was 

 built as far as the miues and they were worked until the autumn of 

 1888, producing 25,000 tons of ore in that time. The openings arc 

 on the north-west and north-east slopes of a low rocky ridge of 

 hornblendic gneiss. The eastern side hill is opened in slope known 

 as Hart No. 1, which is 300 feet deep, on a shoot of ore 20 feet wide 

 and 10 feet thick. At the north end of the hill are New York No. 1, 

 Benson No. 1, Benson No. 2 slopes. Fuller No. 2, is located at the 

 south-west end of the western range of ore. The dip of the strata 

 and of the ore beds averages about 60° to the north-west. In Benson 

 No. 1, the ore was said to have been from four to twenty feet wide 

 for a length of 400 feet. The greatest depth reached was 350 feet
