232 Miscellaneous Localities of Minerals. 
Indurated Talc, Chlorite and Loam. Its Lamine are 
from 6 to 12 inches in length, of a beautiful green. This 
locality isin the middle of the road, and was discovered a 
few years since by the workmen in repairing the road at 
this place. I obtained from ten to twelve hundred weight. 
Dr. Chas. B. Halsey was the first mineralogist who ob- 
tained specimens at this place—(about two years ago.) _ 
Fasciculite of Mr. Hitchcock, on Mica Slate 1 mile N. E. 
of Woonsocket village. . . 
Micaceous Oxide of Iron in quartz—-Blackstone factory. 
In Jounson 4 miles N. N. W. from Providence, Gran- 
ular Limestone, Steatite, Indurated Talc, French Chalk, and 
varieties of Zremolite. ; hie 
Fire Stone and Whet Stones. Woonsocket Hill is about 
a mile westerly of Woonsocket village, Smithfield. It ex- 
tends about a mile northerly and southerly, and is com- 
posed of a Quartzose rock of peculiar qualities. It ap- 
pears on the surface on various parts of the hill. The 
hil terminates abruptly in projecting ¢liffs at the southern 
extremity, and slopes in a gradual declivity on the north- 
ern extremity. It declines regularly to the N. E. It ap- 
pears to be a kind of sandstone slate or micaceous sand- 
stone—it is fissile, and some of it is easily quarried. Some 
of it is easily pulverised and very white, other parts of it 
are hard to break and traversed by veins of compact 
Quartz. The Quartz ofthis rock is granular and of an- 
gular structure, a little yellowish, and some of it is reddish 
—the Mica is reddish and white. This stone has the 
property of withstanding the effects of heat, beyond any 
other, and has been transported in waggons 50 or 60 miles 
for furnace hearths for 40 or 50 years. It is called ‘‘ the 
furnace stone,’ when pulverized and rubbed with tallow, on 
what the mowers call rifles, it answers extremely well to 
sharpen their scythes, and has long been used by them. 
It loses some of its sharpness and strength by being expo- 
sed to intense heat, although it pulverizes more easily. 
The famous Whetstone Quarry commences about 5 2 
mile N. E. of Woonsocket Village, extending about a mile 
S.W. From6 to 8 thousand dozen of whet stones have been 
quarried ina year. But 3 thousand dozen would be an 
average, perhaps, for ten years past. 
Note.—Dr. S. Robinson will exchange the minerals of 
Rhode-Island for those of other districts.
