TO THE EDITOR. 
DEAR SiR, 
] Have recently obtained the following minerals, from lo- 
calities which have probably never before been visited by a 
mineralogist, viz. 
1. Epidote, from Smithfield, handsomely crystallized. 
2. Fibrous and glassy Tremolvte, from Johnston, 21 miles west 
of this town. They occur in magnesian limestone, pretty

is in flattened crystals, confusedly aggregated. The glassy 
variety was found, and noticed in your Journal, by the late 
Mr. Taylor, within half a mile of the above. 
3. Fetid Quartz i abundance, in clay state, fromCr anston. 
When struck with a hammer it exhales an odour resembling 
burnt animal substances. 
4, Actynolite, one fourth of a mile north-east of 
Leach’s iron ore bed, in Cranston. This is by far 
the most interesting locality Rhode Island affords, both 
gn account of the beauty of the mineral andits great abun- 
dance.* ‘There appears to have been an excavation made 
many years since, into a talcose rock, and the actynolite is 
found in the masses thrown out. I noticed many pieces, how- 
ever, as large as a man could well lift, consisting entirely of 
actynolite, Th» most beautiful specimens are those which 
occur in indurat:d talc, as the actynolite appears very dis-

gists who have recently carried off eur minerals by the cart load.
