ly more than two degrees, and an abrupt descent of a few feet imme- 
diately before. The earth above, will never be a serious hindrance to 
excavation, when the more accessible portions shall have been exhaust- 
ed. In the supposition that the area of the quarry which may be work- 
ed is but five acres, and that its average depth is but nine feet, there are 
14,520 cubic yards. Hitherto the dressed stone have been little used ; 
the want of some channel of communication with distant markets hav- 
ing prevented extensive sales. 
Talbot's quarries are a half mile south from Butler's, and have been 
opened some time. They are in the same strata. 
Fisher's and Brace's, have furnished some. At Brace's the ledge 
has not been searched for, there being an abundance of fragments of 
requisite sizes. 
In all this sandstone, of a greyish and sometimes of an olive colour, 
there is a difference observed in the ease with which they can be dress- 
ed. It was thought to be owing to the relative coarseness of the grains 
of sand. 
If there could be established means of communication with the Gene- 
see Valley canal, the stone of these quarries might be distributed 
through the southern tier of counties along the New-York and Erie 
rail-road, as well as along the canal, and eventually Pennsylvania mar- 
kets might be supplied. 
Hancock's quarries about five miles northeast from Machias Corners, 
in Freedom, are of finer grain and micaceous. Grindstones are manu- 
factured by Mr. Hancock, from them, which are said to be of an ex- 
cellent quality. 
Roselle's quarries, in Freedom, are in the same strata. These stone 
are the most strongly impregnated with bituminous matter, of any seen 
in the district. Near Roselle's quarries, is the oil spring abeady de- 
scribed. 
Mc Clure's quarries, one mile west of Franklinville, furnish a fine 
grained bluish sandstone. 
Half a mile west of Cadiz, a quarry has furnished a few cubic yards, 
of an olive and greyish sandstone. The layers are thin, but in all five 
feet thick, with a thinner layer of fossils, separating each two of the 
strata. A heavy deposit of shale overlies the whole.
