of from two to three miles. Many favorable situations occur for the 
extraction of building stone of an excellent and durable nature. This 
rock varies in colour from a light to dark blue, is of a granular texture, 
sandy, and emits a bituminous odor on percussion. It occurs in lay- 
ers, of from one to three feet in thickness, having a horizontal posi- 
tion, and an elevated and dry situation. We noticed two quarries near 
the line of the Sodus canal now in progess, and which belong to the 
company constructing said canal. 
Uttoe's or Miner's quarry, lot 132 in Rose, is on the head waters of 
Sheldon's creek. The rock occurs in extensive layers, two or three feet 
thick, of a dark blue colour, granular texture, and highly bituminous. 
This quarry has furnished an approved stone, which was employed in 
the locks of the Erie canal, at Clyde. 
Henderson's quarry, lot 141 in Butler, affords large blocks of a build- 
ing stone, similar in all respects to that last mentioned. 
Roe's quarry, in Butler, furnishes a dark compact limestone, which 
is bituminous. It is employed in building, and also for the manufacture 
of lime, of which it affords an article of excellent quality. It is a mag- 
nesian limestone, and contains only a few fossils, among which we re- 
cognise Cytherina. 
A compact shell limestone which occurs near the Shakers' mill in 
Sodus, is quarried out as a marble, and used for ornamental purposes. 
It is so employed at Geneva. 
The range of sandstone in this county is narrow, not exceeding two 
miles in width, and lies immediately along the lake shore. It does not 
appear to be used for architectural purposes; indeed, it is too soft, slaty, 
and argillaceous, except m the town of Wolcott, where the upper lay- 
ers are hard, sUiceous, and occasionally pass into conglomerate or pud- 
ding stone. These upper layers have been quarried and used in the con- 
struction of furnaces, as at Wolcott. (See article Firestones, p. 324.) 
At the forge on Salmon creek, the sandstone contains abundance of the 
Fucoides Harlani. — (Conrad.) 
Gypsum. 
The range of gypseous rocks extends on both sides of the Erie canal, 
along the southern part of Wayne county, but generally lies too low for 
profitable exploration. At Clyde they meet gypsum in wells at the 
depth of 25 feet. Wells at Lyons have struck plaster at 40 feet, and 
also in Palmyra, at about the same depth.
