TO THE EDITOR. 
Dear Sir, 
I] nave 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 Tremolite, from Johnston, 24 miles west 
of this town. They occur in magnesiadn limestone, pretty 
abundantly. The former is fine fibrous, grouped in radiated 
and fascicular masses, white and yellowish white. The latter 
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 in 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 
on account of the beauty of the mineral and its 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 eutirely of 
actynolite. The most beautiful specimens are those which 
gccur in indurated talc, as the actynolite appears very dis- 
* It is in sufficient quantity to satisfy the rapacity of those mineralo- 
gists whe have recently cerried off eur minerals by the cart load.
