46 Miscellaneous Localities of Minerals. 



In Rhode-Island, 

 4. By J. G. and J. B. Anthony. 



1. Fluor SpaVi crystallized and massive in quartz, tra- 

 versing granite about two miles east of Cooke's tavern in 

 Cumberlanu, colour white, smoky, purple, and violet. When 

 placed on hot coals, it phosphoresces with an intense eme- 

 rald-green light — a quantity might be obtained at this place 

 with but little trouble. 



2. Smoky Quartz, at do. associated with fluor spar. 



3. Common Jasper, green, blue, gray, white and spotted 

 at Diamond Hill. 



4. Asate^ is found in great abundance at Diamond Hill 

 and its vicinity, it is composed of quartz, jasper, chalcedo- 

 ny and bornstone variously disposed in stripes, spots or ir- 

 regular figures, is susceptible of a fine polish and frequently 

 combines a beautiful assemblage of colours. 



5. Radiated Quartz, frequently ferruginous, is associated 

 with jasper and agate on Diamond Hill. 



6. Smoky Quartz, at Smithfield in amorphous masses of 

 considerable size. 



7. Limpid do. at do. in crystals and crystalline masses. 



8. Feldspar, massive, and in large crystals at do. 



9. Beryl, at do. it occurs crystallized in veins of granite 

 traversing gneiss and rarely, in the contiguous gneiss — col- 

 our, pale yellowish and bluish green — the granite is com- 

 posed of quartz and feldspar only, or with a very minute 

 portion of mica, crystals of one and a quarter inches in 

 diameter have been obtained from this place, they are from 

 the veins on the surface and are seldom regularly termin- 

 ated — were the rocks in the neighbourhood blasted, it is 

 probable that large and perfect crystals might be procured. 



10. Grnphic Granite, at do. associated with beryl. 



11. Ligniform Asbestos, at do. 



12. Schorl, in brilliant and perfect crystals in a fine 

 grained granite at do. 



13. Garnets, in gneiss, do. 



14. Mica, of a yellowish green colour in six sided tables 

 attached to the sides of cavities in the gneiss which con- 

 tains beryl. 



15. Specular Oxide of Irtn, a^ssooxzXedL with Quartz ta 

 Cranston.
