Miscellaneous Localities of Minerals. 51 



10. Granite, at the amethyst locality, Mount Hope Bay, 

 Bristol. 



1 1 . Gray Wacke Slate, forming a ridge on Popasquash 

 Island, W. of Bristol. 



12. Gray Wacke, forming the shore near Patuxet Vil- 

 lage. 



13. Gray W^«cA;c, containing (Chlorophane) fluor spar, 

 Providence. This rock, of a peculiar structure is frequent 

 in this vicinity, and in Seekonk, Johnson, and Cumberland, 

 where it is frequently traversed by veins of quartz, con- 

 taining fluor spar ; it sometimes contains small masses of 

 various simple and compound minerals. It emits an argil- 

 laceous odour when moistened. 



14. Gray Wacke slate, Johnson. 3 miles from Provi- 

 dence. Some of the Gray Wacke of this vicinity, about 

 3 miles below Providence, has straight seams, which in 

 quarrying, give one good face to the stone. Those build- 

 ings, erected from this stone in the town, precisely resem- 

 ble in color &c. those built of greenstone in New-Haven, 

 and at a little distance, and without examination would 

 easily be mistaken for the same. 



15. Limestone, from a bed formerly quarried. Johnson, 

 3i miles from Providence. 



16. and 17. Granite, Johnson, four to six miles from 

 Providence, lately quarried to a considerable extent, and 

 adding beauty and durability to the new buildings in Prov- 

 idence. 



18. Gneiss, Scituate, about 17 miles from Providence, 

 extensively quarried, specimens of which may be seen in 

 most of the new buildings, and in flag stones in Providence, 

 which perhaps may boast of having the handsomest side- 

 walks of any town in the U. States — laid with gneiss and 

 mica-slate from Connecticut. 



19. Serpentine, in a granitic hill, five miles from Provi- 

 dence, on the left of the Smithfield turnpike, on ' Jenke's 

 Hill,' Smithfield. 



20. 21, 22, and 23. Varieties of the limestone, at the 

 Harris lime rock, Smithfield, about eight miles W.of N. from 

 Providence. What is called " the Harris Lime Rock,'''' 

 forms three hills, about 200 yards from each other, situa- 

 ted'in a kind of basin, surrounded by hills. The southern, 

 or first has not yet been quarried. At the base of this, is-
