Limestone 



New York State is abundantly supplied with limestone. In the 

 western and central parts of the State are the Onondaga and 

 Nia^gara formations ; in the northern section the crystalline limestones 

 of St Lawrence county; in the east the Helderberg limestones; and 

 in the southeast various crystalline hmestonies. These vary greatly 

 in purity and this variation makes it possible to obtain a stone suit- 

 able for almost any purpose. 



The stO'ue discussed under this heading, with the exception of 

 some crystaUine limestone used for flux or lime making, is all of 

 a niOincrystalline, massive character. The ston,e used so extensively 

 in Portland cement manufacture is not included in the tabulations. 



The total production of limestone for 1909, exclusive of that u^sed 

 in cement manufacture was valued at $3,300,383, a slight gain over 

 the value for 1908 which was $3,119,835. 



Among the counties Erie showed the largest production with 

 a total of $853,764, a large increase over the production of last 

 year. It was followed in descending order by Dutchess, Onondaga, 

 Genesee and Jefferson counties, all of which showed large gains 

 with the exception of Onondaga, whose production took a decided 

 drop. 



The production was distributed among the various products as 

 follows: crushed stone $1,744,314; building stone $217,109; lime 

 $452,874; furnace flux $434,311 ; other uses $451,775. All of these 

 took part in the general increase in production but the stone used 

 for building purposes which fell from $245,655 in 1908 to $217,109 

 in 1909. The lime made in connection with the products of the 

 Solvay Process Co. and the Union Carbide Co. is included under 

 " other uses."
