BEEKMAN MINE, Beekman, Dutchess County. — The mine in 

 the village of Beekmanville is named from the town in which it is 

 situated. It is opened on the north-west of the village street 100 

 yards, and within a quarter of a mile of the Clove Branch railroad. 

 The mine is 500x300 feet and 70 to 90 feet deep. The stripping is 

 a glacial drift, which is five to twenty feet thick, underlain by an 

 ochreous clay, in which there is some ore. At the north-west there is 

 a crumbling, slaty rock exposed by the excavation, which dips east- 

 southeast steeply. The ochreous earths on the south and west sides 

 show south-dipping layers — the lines of original stratification in the 

 rock. The ore is quite firm and has to be blasted down. A large 

 proportion is rock ore which is sorted out in the mine from the^wash ore. 

 For washing, water from a stream 3,500 feet northward and with a 

 good head, is led to the washer at the south side of the mine. The 

 hoisting is in cars, pulled up a slope 350 feet long by a slide valve 

 engine 8x24". Two tubular boilers, one Knowles steam pump, one 

 Plunger pump and one Bradford washer are in use. The pit water 

 is raised to a drain west of the mine. The ore is shipped to Pough- 

 keepsie furnaces. This mine has been in operation continuously for 

 19 years, since it was first opened. It is owned by A. Tower, and 

 worked by A. E, Tower & Bros., all of Poughkeepsie. 



CLOVE MINE, Unionvale, Dutchess County. — Two mines have 

 been opened in the Clove Valley, three miles north-east of Clove 

 Spring Iron Works, the terminus of the Clove Branch railroad. The 

 mine at the south-west is the property of A. Tower, of Poughkeepsie. 

 It was opened about 1834, and was worked until February, 1888. 

 The ore was found bounded on the south-east by an irregular wall of 

 grey limestone, and covered by ochreous clay and glacial drift. On 

 the west the rock was not reached, but further west, the valley is 

 bounded by the Scott mountain ■ — a rocky ridge of hydro-mica slate. 

 The ore was carted to the Clove Branch railroad, and thence shipped 

 to Poughkeepsie furnaces. 



THE CLOVE SPUING MINE is separated from the above by 

 an unbroken surface of about 500 feet. It is similarly situated and 

 apparently in the same body of ore. The pit is nearly 900 feet long, 

 from north-east to south-west, 200 feet wide and 130 feet deep. The 

 slope on the west side is 200 feet long. The "stripping" consists of 

 drift, with many large boulders, from 6 to 30 feet thick, and under it 

 ochreous earths, in which there is more or less ore. A gray lime-
