Connected with these localities of the ‘sulphuret of 
ron is a ciréumstance »worthy of notice: .it is, if 
may use the eneneson the existence of a sort of minia- 
ture volcanoes. The late Dr. Dwight, in his Travels, 
Vol. Il. p. 203, imhis Seoctapess of Stafford, makes mention 
of a volcanic eruption, reported to have taken place in that 
town. The spot alluded to is a high rock forming the west- 
ern bank of the valley of the Willimantic, and distant nearly 
a mile from the springs. Similar-eruptions are said (o have 
taken place on the mountain that has.been named in Somers. 
After a long continued rain, it is said by some of the in 
ants living near the place, that reports have been heard from 
the mountain, in frequent succession, louder than that of 
musketry. On examining this rock, not long since, a small 
hole, of about an inch and a fourth in diameter, was found, 
which extended to a cousiderable depth into a bed of the 
iron ore. The mouth mena was extended in the form 
ofa tunnel, and-was filled with leaves, earth, and a mixture 
of the sulphate of iron _ Eruptions. of the kind mentioned, 
have probably taken p place on this spot. In Monson, also, it 
is ro 3 that some years since, a similar eruption took place 
on a spot which abounds with’ this ree and there are 
not wanting indications of the trath of the story A recent 
account, we have had in the public prints, of a volcanic erup- 
tion, in some town, in the state of New-York, may perhaps 
be ~—— in the same manner. 
7. Magnetic Tron._This js found in abundance scattered 
through the gneiss rock, in Monson. A specimen also I 
have in my possession, of the size of a hen’s egg, taken from 
among the gravel stones of an old field in Palmer.
