more free from pyrites than usual. In these mines are large bodies of 
the ore in black powder, which is entirely destitute of pyrites. Umber 
also is connected with the Forshee mines, and appears to be abundant 
and of fair quality. 
The minerals, associated with the ore of the Forshee mines are red 
garnet, brown tremolite, green coccolite, serpentine yellow and black, 
calcareous spar, asbestos and mica. 
Five miles southeast of Monroe works is the rich iron mine, the pro- 
perty of Hudson McFarlan, Esq. It is a fine rich ore, strongly magne- 
tic. It has not been extensively wrought, although there are evidences 
of an abundant deposit. Connected with this mine, are mica, horn- 
blende, or as this mineral is generally called in Cornwall and Monroe, 
black-jack-sahlite, magnetic pyrites. 
The Greenwood mine is t^vo miles southeast of the Greenwood fur- 
nace in Monroe. It is in the granitic gneiss. Three layers of ore, se- 
parated by a few feet of rock, are exposed there. The middle one of 
these is only sufficiently uncovered to reveal its thickness. This one is 
nine feet. This mine is covered by what some miners call a rider, that 
is, rock lying nearly or quite flat, or hanging in a direction contrary to 
the dip of the ore and rock in which it lies. This rock roof covers this 
mine; after its removal, the ore and its walls lie conformably, that is, 
dipping to the southeast. The ore is mostly compact and hard, con- 
taining considerable sulphur, and requires roasting. It is associated 
with quartz, hornblende and mica. Preparations are making to use it 
extensively. 
Long mine is about five miles southwest of Southfield furnace, and 
two and a half miles west of the saw works. This mine has been 
known since long before the revolution, and is the only one in the county 
at which any thing like systematic mining has been attempted. This 
ore has its bearing and dip corresponding with those of the rock. Only 
one layer of the ore has been w^orked, which is six feet thick. The 
ore is strongly magnetic, and said to be as good as any in the High- 
lands. It is associated with hornblende, sahlite, slaty gneiss, gneissoid 
hornblende and reddish granite — has a small quantity of pyrites — re- 
quires roasting, and gives a red short iron. 
This mine has been worked 300 yards in length and about 40 in 
depth. The early working has all caved in; but fine pillars of ore sus- 
tain the hanging wall where the work has been recently prosecuted.
