Bog Iron. 
Several deposits of bog iron were noticed in the county, which, how- 
ever, are not explored, so that their extent is unknown. It occurs in 
solid masses one mile west of Albion, on the farm of Stephen B. Thur- 
ston. 
One mile east of Ridgeway corners, on the farm of David Hooker, 
on the south base of the ridge, bog iron occurs in grains, both loose and 
forming small masses in the soil, which is here a sandy loam. It has 
the local name of shot ore. Bog iron also occurs one mile, and one and 
a half miles west of Ridgeway corners. 
In Ridgeway, between the ridge and west branch of Oak Orchard 
creek, is a swamp covering 400 or 500 acres. This contains an abun- 
dance of bog ore, which has been manufactured into iron by Mr. Ben- 
nett. 
Quick-lime. 
The limestone range in the southern part of this county furnishes an 
abundant supply of materials for lime of an excellent quality. Kilns 
are erected south of Shelby, at Millsville, about one mile south of Wil- 
liams' quarry in the town of Barre, and at other places in the limestone 
region. At Barre, and on the range to Clarenden, the rockis of a light 
blue colour, and occurs in large irregular and ragged masses, either form- 
ing ledges, or scattered profusely over the surface. It resembles very 
closely in character the limestone which occurs at the Bullshead, one 
mile from Rochester, and contains generally the same fossils. 
Two miles west of FarwelPs mills, a dark blue limestone occurs, bi- 
tuminous, and containing fossils. It is a magnesian limestone. 
Hydraulic Lime, 
We were informed that the upper layers of the rock at the falls of 
Oak Orchard creek, at Shelby, are advantageously used for the manu- 
facture of water cement. They consist of a sandy limestone, but do 
not resemble in texture and other characters the best hydraulic lime- 
stone. 
At FarwelPs mills, Clarenden, there is a deposit of sandy limestone, 
slightly bituminous, agreeing in texture, colour, and other characters 
with the most approved hydraulic limestones of the western counties. 
It occupies the brow of the hill which rises immediately behind the 
village, and according to Judge Farwell, has been burned, and convert- 
ed into water cement of an approved quality.
