Limonites of Dutchess and Columbia Counties. 59 



KELLY MINE, Northeast, Dutchess County.— One mile north of 

 Mt. Riga station and at foot of mountain, was opened in 1880 and 

 was closed in April, 1888. 



MORGAN MINE, Ancram, Columbia County. —The Morgan 

 mine is one of the oldest mines in this region, and is said to have been 

 opened in 1776 by the Livingstons. It is near the western base of 

 the Winchell mountain range, and one and a half miles south of Hal- 

 stead station, on the New York and Massachusetts railroad. The 

 ore appears to have been covered by a mantle of drift, 8 to 20 feet 

 thick. At the north-east end of the old pit a stream has cut down 

 through the earth and boulders and exposed a section 20 feet thick, 

 of superior carbonate of iron. This ore on the weathered surfaces is 

 reddish-brown in color, but under the thin, oxidized coating it pre- 

 sents the characteristic gray-white shade of carbonate ore. An 

 analysis of this ore, made recently, shows it to contain 48.1 of metallic 

 iron, 0.42 of sulphur and .038 of phosphorus. The carbonate or 

 " white horse" has been found in some shallow, exploring pits on the 

 adjoining Knight property, to the south. The property is owned by 

 Albert Tower, of Poughkeepsie. This mine has been known also 

 as the MacArthur place. 



REYNOLDS MINE, Ancram, Columbia County.— The Reynolds 

 mine is at least a quarter of a mile west of the mountain, in the lime- 

 stone valley, and a half mile east of Halstead station on the New 

 York and Massachusetts railroad. Prior to the building of that rail- 

 road there was a branch railway to Boston Corners. There are two 

 large pits from which a large quantity of ore has been taken. The 

 mine buildings and the dump are on the west of the pits ; the washer 

 is on a stream between them. The rotten rock over the ore is strati- 

 fied, and has its beds dipping easterly, at an angle of 20°. The mine 

 has been idle since 1887. It was opened in 1857. 



WEED MINE, Copake, Columbia County. — The Weed mine is 

 on the west side of the N. Y. and Harlem railroad, and north of the 

 line of the Hartford and Connecticut Western railroad, and one mile 

 from Boston Corners. It was first opened in 1840. In June last it 

 was re-opened by the present owners, the Millerton Iron Company, 

 Irondale, Dutchess county. The ore body has been uncovered for a 

 length of 1,600 feet, from north to south, and over an average width 

 of 70 feet. A depth of 120 feet has been reached in the lowest part
