Its location will be easily understood from the accompanyingtopographical sketch.

Thelower portion of the bed, which contains much manganese and less ironin proportion, is of a mottled gray and dull reddiah color at the summit,and at the distance of two or three hundred yards along the slope, is alight colored and gray and spotted (black and dirty white,) ferriferous,mauganesian slate. Occasional sheets of laminated black oxide of man-ganese occur, one or two inches in thickness. Some parts of the bed areslightly magnetic. The outcrop, or rather the terminal ftice of the bedat the opening, on the summit of the hill, is shown in the annexed dia-gram. The thickness is about 36 feet at this point, and diminishes to 20ar the lower quarries, 200 to 300 yards distant. Ore, tneK2Ka/ty<m»»*;.. O-arruc ftl>rp. OritiM,Gnsit* Buckhorn ore is properly described as specular; it is of a dull, dark gray toblackish color, subcrystalline structure, and uneven fracture. The streakis dark red. Occasional fragments of the ore show a tendency to lamina-tion, and in such cases the divisional planes are commonly coated withmica crystals. The character of this ore is very like that of the IronMountain, Mo., and its extent and mode of occurrence strongly suggestthe Pilot-Knob. It is at least equal to either of these notable iron ore
