138 NEW YORK STATE MUSEUM 



The ore body continues to the south beyond the pit and onto 

 the property of Mrs C. B. Miller where some ore was taken out 

 through shafts, one of which is across the highway to the southeast 

 of the pit. 



Between Boston Corners and Mt Riga at the foot of the high 

 ridge which lies along the state line are the Kelly and Dakin mines, 

 of which few particulars are to be had. The Dakin is a little north 

 of Mt Riga and the Kelly still farther distant. 



Weed mine. The Weed mine has been recently under operation 

 by Barnum, Richardson & Co. for supply of their furnaces at 

 Limerock, Conn. The mine is equipped with a new hoist and 

 washing plant. The property is i| miles north of Boston Corners, 

 between the Harlem Railroad and the Central New England Rail- 

 road. The ore is opened by a long trench and followed underground 

 on the easterly dip which carries it below the schist hanging wall. 

 The foot wall is of the same schist, but of less weathered character. 

 The dip is about 35°. The mine had yielded 168,000 tons up to 

 the time of Putnam's report for the tenth census. An analysis 

 reported by Smock shows 43 per cent iron and .11 phosphorus. 



Co pake mines. These are at Copake Iron Works on both sides 

 of the Harlem Railroad. There are two openings to the west of 

 the tracks which represent the earlier operations while the larger 

 and more recently worked mine is northeast of the station. The 

 latter is a pit 500 feet long and up to 200 feet wide opened in glacial 

 materials, except at the northeast end where a bluish white limestone 

 appears showing a dip of 25° or so to the east. The ore appears 

 to lie in a depression of the limestone and apparently near the top 

 of the beds, as the schist may be seen nearly on a line with the pit 

 to the north. The contact between the two formations is approxi- 

 mately indicated by the brook which flows south by the pit. There 

 are small openings just north of the main pit and prospects with 

 indications of ore for some distance farther north. The mine was 

 closed about 1888. It was operated in connection with the Copake 

 furnace both owned at present by John Mills, Twin Lakes, Conn. 



There is more or less carbonate intermixed with the limonite, and 

 in one of the prospects on the north end it is practically the only 

 ore. Putnam reports that a sample of washed and lump limonite 

 combined returned 46.8 iron and .424 phosphorus. A sample of 

 the carbonate contained 30.8 iron and .248 phosphorus.
