I ASSEMBL-Y 
Vast quantities of ore have been taken from this mine without any ap- 
pearance of its failing. It belongs to the Messrs. Townsend. Only 
one dyke has ever occurred in this mine; it was one foot thick, and 
made no change in the direction of the ore. It cannot now be seen — 
is worked 70 feet deep. 
The Patiei'son mine is half a mile southwest of Long mine — ore very 
similar in all respects — makes excellent red short iron — is in the gra- 
nitic rock. The ore is twenty feet thick — opened 150 feet long. About 
10,000 tons of this ore have been used. It is strongly magnetic, and 
has polarity. 
About the middle of the mine, as now open, is a transverse slip or 
heave; the mine and its walls appearing as if they had slid downwards 
and forwards to the southeast, causing an angle in their line of bearing. 
It is the property of the Messrs. Townsend. 
Mountain mine, intone mine^ Conklin mine and JVeit? mine^ are a 
group from twenty-five to fifty rods northwest and north from the Pat- 
terson mine, belonging to the same proprietors. They lie in nearly 
parallel beds; the ore of all apparently similar — a rich black magnetic 
oxide, possessing polarity. Ore to the amount of 5,000 tons has been 
used from these mines; the ore and walls nearly vertical; layers of ore 
from four to eight feet thick. The new mine has a cap of rock lying 
nearly horizontal; associated minerals, sahlite, hornblende, and feldspar. 
The sahlite is laminated and very beautiful; iron red short. 
Crossway mine, upon the same estate, is 400 or 500 yards southwest 
of Mountain mine. This bed is 14 feet thick, and has been wrought 
65 feet deep and 150 yards in length; ore and iron very similar to those 
of Patterson mine; moderately red short; ore and walls nearly vertical; 
28,000 tons are supposed to have been used from this mine; associated 
minerals, hornblende, epidote, mica and adularia. 
Sterling mines ^ belonging to the same gentlemen, are about a mile 
southwest from Crossway mine, at the south end of Sterling pond. 
These mines, or this vast mine, is in the northern end of a mountain of 
moderate elevation; its length is about three miles. The ore is rich, 
granular and compact; its product, cold short iron; is one of the earliest 
known iron mines in the United States. The minerals connected with 
this ore are crystallized green hornblende, sahlite, green mica, flesh-co- 
loured feldspar, and the ore in octohedral crystals. The rocks are gra- 
nite, and a coarse showy sienite. There is abundant evidence of great
