disturbance in the stratification in this mountain, and in all the vicinity. 
The rocks dip to the northeast and east, with the ore conformable to 
this arrangement; at least such is the general arrangements, so . far as 
can be ascertained in this mass of confusion. The ore alternates with 
the rock; how often, cannot of course be ascertained. The ore lies na- 
ked about fifty rods wide by 150 yards in length. In many places its 
surface is even and polished as if it had been ground off by the sliding 
of the rocks. 
The Belcher mine is upon the same property, and very similar ore to 
that of Sterling; it makes cold short iron. It is one and a half miles 
southwest of Sterling mines, and at the southern termination of the 
same mountain. The ore has been worked about 115 feet wide with- 
out finding a rock wall on either side. It is believed to be a prolonga- 
tion of Sterling mine. 
Red mine or Spruce Swamp mine is nearly three miles south of 
Long mine. All the ores of this mine are magnetic and full of pyrites, 
so much so that only a moderate amount has been used. They decom- 
pose rapidly when dug up and exposed to the open air. In this man- 
ner the surface of this mine has all been reduced to powder of an iron- 
rust colour; like several other mines the ore alternates with the rock. 
Magnetic oxide of iron is also found of good quality in many places 
in Cornwall; but these have not been opened to much extent. Near 
the foot of Butter hill, on the land of Mr. Clarke, on Deer hill, on the 
land of Mr. Luke Wood, and that of Thomas Titus, are indications of 
valuable deposits of this ore. 
Two and a half miles west of the village of Canterbury, in Corn- 
wall, is the hematite or limonite mine of Mr. Thomas Townsend. For 
the last two years this ore has been considerably used, and although a 
lean ore it makes excellent iron. It is mostly in powder, or very small 
fragments, mixed with balls and pieces of the hematite, of a few pounds 
weight. It lies in limestone rock, and between the limestone and the grit 
rock. These rocks, where connected with the ore, are decomposed to 
great extent, and mixed in the state of powder with the ore; hence the 
ore requires washing. 
This stratum of limestone and hematite can be traced across this town 
into Monroe, until we reach the magnetic oxides already noticed. It is 
seen a quarter of a mile north of the Clove mine, and at many places 
intermediate between this and the Townsend mine in Cornwall. The 
distance between these extreme points is full ten miles.
