~ Compact brown oxid of Jron—associated with the — 
tite at the ore bed. 
Ochrey brown oxvid of Iron—Yellow ochre is in conti 
erable abundance at the same localit 
Argillaceous oxid of lron.—In Cleaveland’s mineralogy 
granular argillaceous oxid of iron is said to be found in 
this town—but it must be a mistake—no variety of this is 
found here but the common, which has a compact struc- 
9 ture, color yellowish, sues conchoidal.

(Barrue Monteith,) bal a penile east of the meeting-house.

distant which ts very rich. It is also met with in mony

* The formation of the ore in this town is involved in some difficulties. 
While the position of the stalactites indicates the action of water, and mre

stalactical ore. For Le heat be the

action of fire at el | you cannot believe that the inside of a ball four 
inches in diameter has been melted and the adjacent parts a’ 
+Cadmia is not produced when the ore is previously roasted, being
