38though it requires much'more heat to smelt, thai ) other ores,yet it produces an iron of excellent quality.In this district this ore occurs in .the white crystnlline lime_stone, and is generally found at or near the junction of thatrock with gneiss, syenite and granite. Large bpwlders of itare found all along the southeastern border of the white limestoneformation fl'om the New York State ]ineaqrossthe Stateto Pennsylvania. A careful examination of the district willundoubtedly bc the means of developing extensiye deposits ofthis valuable ore. Among the localities that have alreadybeen worked to a considerable extent, I will refer to but two_viz:,the Simpson and Andovcr mines..0• SIMPSOIq:MINE_.This mine is in Vernon Township, half n mile from Smithville,and two and a half miles northeast of Hamburgh. The 'ore occurs in the" form of a bed or irregular deposit, fromsix to ten feet in width, in the white limestone. Excaw_tlonshave been made into it to the depth of twenty feet," fromwhich considerable quantities have been removed and smeltedin the old ]]amburgh Furnace, yielding an iron of superiorquality. This ore has a brownish red eolor,:a.fine steelgrainedtexture, and a metallic lustre. A large proportion ofit is quite pure and almost entirely free from foreign materials.ANDOVER:MINE.• !This mine, celebrated as one of the oldest and richest iron• mines m this country, is in the township of Newton, near thevil.lage of Andovcr, audin the same geological rafigb and for-_mation as the mine last n_entioncd. It has been worked atdiffcreht times from the year deventeen hundred and sixty tothe preseut, and is noted for furnishing an" ore peculiarlyadhpted to the manufacture of steel. _ The ore occurs in the• Hen.
