Report of the State Geologist. 



the quarry, is fifteen feet, making a total thickness of thirty-five feet. The 

 rock at the Young quarry is of about the same thickness. 



About 150 feet north of the Fogelsonger quarry, is another known as the 

 " Syndicate " quarry, owned by Louis Wild, Joseph Mayer and Henry Smith, 

 of Buffalo. At present the quarry is not worked. 



The Corniferous Limestone. This formation furnished the greater part 

 of the stone quarried within the county. The largest quarry interests are 

 located within the limits of the city of Buffalo, and comprise two districts. 

 The first includes the quarries near Main street, from the Almshouse to the 

 Buffalo Cement Works. These are at present idle with the exception of 

 the Grattan & Jennings quarry, which is selling a small quantity of stone. 

 The second district, locally known as " Jammerthal," includes the region on 

 both sides of Fillmore avenue, from LeRoy avenue to Delavan, and extending 

 east along LeRoy to Worcester place, and along Delavan avenue to Dutton. 

 The limestone is very cherty, and on that account hard to cut, but makes a 

 very strong and durable building material. The layers are from twelve to 

 twenty-four inches thick, and blocks can be obtained of almost any desired 

 size. For this reason the stone is well adapted for railroad bridges, footing 

 for piers and for other heavy work. It is also the principal material for cellar 

 and foundation work for buildings of all sorts. The greater part of the stone 

 quarried here is used in Buffalo and by the railroads which enter this city. 



Besides the quarries already mentioned, there is a small one belonging to 

 Cutter & Bailey near the New York Central railroad and Bailey avenue. 

 Another, from which a few cords have been taken during the past season, is 

 near the canal, just below the railroad bridge at the Front. 



The greater number of quarries within the county, and outside of the 

 city of Buffalo, are located near the southern edge of the Corniferous outcrop. 

 The limestone contains less chert and is somewhat thicker bedded. The fol- 

 lowing section of Martin Keiffer's quarry, near Depew, illustrates very well 

 the conditions which exist at that horizon. The quarry is situated near the 



north bank of Cayuga creek.
