130 Report on Building Stone of New York. 



Bennett's limestone quarry is west of the city. Only one to two 

 men are employed and the product is unimportant. 



The gray limestone of these Auburn quarries has been used largely 

 and effectively in the five beautiful church buildings ; in the city hall ; 

 in twenty-two store-houses ; in the buildings of the Auburn Theological 

 Seminary ; the State Arsenal and the State prison. They witness to 

 its beauty, both when fine dressed and as rock-face ashlar. 



Seneca Falls, Seneca County. — Small quarries, worked at in- 

 tervals and for local use only, are opened in the limestone along the 

 river at Seneca Falls. 



Waterloo, Seneca County. — Two quarries are opened and 

 worked near Waterloo. They are in the Corniferous limestone 

 formation.* 



John Emmett's quarry is on the Seneca canal, one mile west of the 

 town. A large space has been uncovered and quarried over. The 

 covering on the stone is from four to ten feet thick ; and the quarry 

 courses or beds of blue limestone are, from the top down, as follows : 

 24 inches, 12 inches, lCkinches, 18 inches, 7 inches, 8 inches, 8 inches, 

 26 inches, 16 inches, 12 inches, 15 inches, 18 inches, 9 inches, 18 inches 

 or 14 courses, which are quarried, and which have an aggregate 

 thickness of 17 feet, nearly. The drainage. of the quarry is into the 

 Seneca river. The stone has been used in canal-lock construction 

 and in churches in Geneva and Waterloo. The quarry was first 

 opened in 1842 . 



Loren Thomas's quarry is half a mile south of the town, and the 

 same distance from the N. Y. C. R. R. and the Erie canal. A large 

 area has here been worked over, having a length of 1,000 feet or more 

 from north to south. It has been worked for 60 years, having been 

 opened first by the father of the present owner. The top earth is 

 here from three to ten feet thick. The beds have a dip of 2° in a 

 southerly direction. They are divided by joints, or seams, which run 

 vertically, nearly west of north, at intervals of 30 feet or so apart, 

 and the second a few degrees south of east at about the same dis- 

 tance apart. These joints assist very materially in the working of 

 the quarry. A vertical section shows the following strata : 



1. Blue limestone ._ 25 inches. 



2. Blue limestone.. _ _ 12 inches. 



* The formation is locally known as the Seneca blue limestone, and is in the upper 

 part of the Corniferous or Upper Helderberg group.
