located in the vicinity of all branches of the New York Central rail- 

 road in the State of New York. This fact is due to the influence of 

 limestone belts in determining the jjliysical geography of the State and 

 consequently of the most available lines for the construction of 

 railroads. 



The lime industry is an intermittent one, there being only a few 

 localities where the business of making lime is followed throughout the 

 year. Of these, Sing Sing and Pleasantville in Westchester county, 

 Howe's Cave and Glens Falls are perhaps the most important from the 

 commercial standpoint. At innumerable localities, however, lime kilns 

 are operated intermittently to supply the local demand. The principal 

 manufactures of hydraulic cement are those of Rosendale near King- 

 ston on the Hudson. The industry at this locality is very large and 

 the product is of world-wide reputation. At Howe's Cave an hydraulic 

 cement of excellent quality is. manufactured. The manufacture of 

 Portland cement, which is essentially a combination of carbonate of 

 lime and clay, is an industry of some importance in New York State. 

 One of the principal manufactories is at Warners, Onondaga county.
