Marble 



True marble, a crytalHne limestone, is fairly abundant in Xcw 

 York State, though its occurrence is limited to the metamorphic 

 regions, including the Adirondack region and the lower Hudson 

 valley. The industry is concentrated into three main areas : Gouver- 

 neur, St Lawrence co. ; South Dover, Dutchess co. ; and Tuckahoe, 

 Westchester co. Aside from these there are two firms producing 

 limestone which, as it is capable of taking a fine jxilish and is used 

 for interior decorations and for monumental work, is clas.sed as 

 marble in the trade. The quarries arc located near Plattsburg in 

 Clinton county, where a Chazy limestone is quarried, and at Glens 

 I'^alls, Warren co., where a fine grained Trenton limestone is pol- 

 ished and sold as black marble.
