THE MINING AND QUARRY INDUSTRY 



135 



quarries have been opened at Mayfield and Northville, in Lewis 

 county near Port Leyden and in Franklin county at St Regis Falls. 

 Anorthosite has been quarried near Keeseville, Essex co., and at 

 West Chazy, Clinton co. The stone has a handsome chatoyant 

 appearance when polished, and is adapted for monumental and 

 decorative work.

The aggregate value of the products of the granite quarries in 

 the State amounted last year to $253,955. Building stone was the 

 largest item in the production, with a total valued at $139,414. 

 Among the other kinds represented with their values were: crushed 

 stone, $69,748; rubble and riprap, $30,125; monumenta^l ,stone,

 chester county alone made an output valued at $142,815, consisting 

 principally of building stone, crushed stone and rubble. The re- 

 mainder of the production was distributed among the following

Limestone 



The limestone quarries are the most important in New York State. 

 Compared with sandstone, which ranks second in value of output, 

 limestone is not specially prominent as a building material, but it 

 is more generally used for road metal and concrete. Its wide occur- 

 rence, in connection with its natural fitness for the purpose, has 

 favored the development of an extensive crushed stone trade that 

 covers nearly every section of the State. The manufacture of lime 

 also calls for a large part of the product. 



Among the geologic formations of the New York series, limestone 

 appears frequently. In the Precambric strata of the Adirondacks
