Lime and Cement. 



Lime is produced throughout the State on the outcrops of the 

 Calciferous, Trenton, Niagara and Helderberg limestones. Some 

 of the chief localities are Glens Falls, Howe's Cave, Rochester, 

 Buffalo, Sing Sing, Pleasantville and Tuckahoe. Hydraulic 

 cement or water lime is chiefly produced from beds of hydraulic 

 limestone in the Water lime group at the base of the lower Helder- 

 berg. Rondout and Rosendale, Howe's Cave and the vicinity of 

 Sj^racuse are important commercially in this product. At Akron 

 and Buffalo much water lime is made, but from a lower formation, 

 probably the Salina Group. 



Portland cement is made from marl and clay at "Warner's near 

 Syracuse, and at Wayland, Steuben county; from lime and clay 

 near Glens Falls and at other points. 



Limestone for Flux. 



In the present depressed condition of the manufacture of iron 

 in New York, the production of limestone for flux is but a small 

 industry.
