The total thickness of the section is 18 feet 7 inches. At the south 



side of the quarry, at the top, there is more shaly stone, which 

 answers for common, wall work only. 



There are several derricks in use, worked by horse power. One 

 steam pump raises the quarry water. The stone is carted to the 

 railroad and the canal. The product is largely used for house work, 

 canal and railroad bridge construction. The Waterloo stone can be 

 seen in the basement of the Protestant Episcopal and in the Roman 

 Catholic churches in Waterloo. 



The Corniferous limestone formation has been opened in small 

 quarries at Phelps Junction, in Gidding's quarry Canandaigua, and 

 at Hog Hollow in the town of Victor, all in Ontario county. They 

 do a local business. 



Leroy, Genesee County. — Two quarries are reported as opened 

 at Leroy for building stone. They are in the Upper Helderberg or 

 Corniferous limestone formation. The stone does for common, wall 

 work, and fills the local demand, but it is not exported to any ex- 

 tent. Some of the limestone which crops out north of the town, is 

 said to dress and polish well. 



The same limestone formation has been opened in a small quarry at 

 Caledonia, in Monroe county. 



Williamsville, Erie County. — Several quarries have been 

 opened at Williamsville, ten miles north-east of Buffalo. J. S. & F.
