"Miscellaneous Localities of Minerals. 231 
Yenite, at the same place associated with calcareous 
Spar, Actynolite and Quartz. em 
Sulphate of Iron, same place — coating considerable ver- 
tical surfaces of rock. = 7 te 
Ferruginous Quartz crystallized in closely imbedded pyr- 
amids on siliceous stone, on “* Diamond Hill,” which is 
about 4 miles N. of E. from Cumberland Meeting House, 
and amorphous in detached masses near C. M. H. | 
Micaceous Oxide of Iron, } a mile N. N. W. from C. M. 
H. associated with Quartz and Epidote. ; 
Sulphuret of Molybdena with magnetic oxide of Iron, and 
magnetic pyritous Iron, ia mile N. N. E. from C. M. H. 
at a place called the “ Mine Hole,” on the west side of a 
Hill which overlooks ‘‘ Sneerch’s Pond,” where a shaft 
was sunk for Copper 70 feet deep, 40 to 45 years ago. 
Carbonate of Copper, connected with Magnetic Oxide of 
Iron, same place, also2amile N. of C, M. H. on magnetic 
Iron ore, where a shaft was once sunk. 
Steatite a little distance south of the ** Mine Hole.’ 
Peat in abundance and of good quality on the borders of 
*‘Sneerch’s Pond.” Alsoinameadow iamileN.ofC. M. H. 
_ Zoisite, in veins of Quartz traversing a rock composed of 
distinct angular grains of translucent Quartz, imbedded in 
Quartz finely comminuted, of a yellowish brown colour, and 
hornblende, half a mile N. W. of ‘ Diamond Hill.” 
Fluor Spar, in the same veins of Quartz. 
Galena in small quantities—same locality. 
Schorl, in detached masses of Granite without mica, S. 
of “ Diamond Hill,” and in several other parts of the town. 
Oxide af Manganese. Jt appears at the foot of a hill 
which rises 30 or 40 feet, on the east side of Blackstone 
River 23 miles N. of Pawtucket, in a stratum of 6 to 18 
inches thick, visible 26 to 30 yards in length, 3 or 4 feet. 
above the water, in gravel, resting upon a stratum of 
Ochrey brown Oxide‘of Iron of equal extent with the manga- 
nese. Prof. DeWolf exhibited oxigen gas obtained from 
this manganese, in his Lecture on the 3d inst. before his class. 
Dendritic formations of Manganese on Limestone are 
common at the Harris rock in Smithfield. 
In SmiTHFIELD, I obtained’ 
Green Talc about 4 a mile west of Blackstone river, and 
some more than a mile west of C. M. H. in veins of 6' 
to 12 inches wide running N. and S.., dipping to the west. 
traversing coarse steatite. :
