LIMKSTONK 



The geographical distribution of the limestone formations in the 

 State and the general reference to the quarries for building stone, 

 which have been opened in them, were given on pages 20-22 of this 

 report. The arrangement of the detailed descriptions of the quarries 

 and quarry districts in the order of the geological series, that is, from 

 the Calciferous, up through the Chazy, Trenton, Niagara, Lower 

 Helderberg and Upper Helderberg, has the disadvantage of separat- 

 ing quarries, which belong together in their geographical and econ- 

 omic relations and of grouping some which are in no wke related, 

 excepting in their position in the same geological horizon. The 

 order of arrangement has been so modified in the following pages as 

 to bring together the quarries in their proper geographical divisions 

 and according to their geological position in these several divisions. 

 It is, therefore, a geographico-geological arrangement. And in it 

 the limestones of the Hudson-Champlain valley are described first ; 

 then, the Calciferous and Trenton limestones of the Mohawk valley ; 

 followed by the quarries in the belt of Trenton, which runs north- 

 west from the Mohawk to the St. Lawrence ; the limestones of the 

 Lower Helderberg formations in Schoharie, Otsego and Madison 

 counties come next ; the Upper Helderberg limestones of Onondaga, 

 Cayuga, Seneca, Ontario, Genesee and Erie counties follow ; and, 

 lastly, the Niagara limestone quarries of Monroe and Niagara 

 counties. 



Warwick, Orange County. — A blue, magnesian limestone is 

 quarried in the village of Warwick, on lands of Thos. Burt and others. 

 The quarries are in a hillside. The beds are ten inches to four feet 

 thick, and dip west-south-west. The stone is hard, strong and dura- 

 ble. It has been used for foundations largely, and to some extent for 

 dressed hou^e work in the town. The quarries are not constantly in 

 operation. 



Mapes Corner, Orange County. — A blue limestone is quarried 

 in Mt. Lookout, near Mapes Corner, in the town of Goshen, on lands
