The limestone quarries are first in importance among the stone- 

 working industries of the State. Compared with sandstone, which 

 ranks second in value of output, limestone is not so extensively used 

 as a building material, but it finds more extensive employment for 

 road metal and concrete. Its wide occurrence, in connection with 

 natural fitness for the purpose, has favored the development of a 

 large crushed stone business that covers nearly every section of the 

 State. The manufacture of lime also calls for a large part of the 

 product. 



The noncrystalline limestones, which alone are considered under 

 this head, comprise a variety of rocks as regards their geological 

 occurrence and physical and chemical characters. They are distrib- 

 uted among the Cambric, Lower Siluric, Siluric and Devonic sys- 

 tems. In chemical composition they include every gradation from 

 practically pure lime carbonate to magnesian limestones and dolo- 

 mites and to silicious, aluminous or ferruginous types in which the
