Dark Marble Co. has been purchased by IMr Newton Aldrich and 

 will l>e enlarged, while the other large companies contemplate 

 increasing their output. 



At Plattsburg, Clinton co. the Rutland-Florence Marl>le Co. 

 during the year quarried a large amount of Chazy limestone which 

 was sold as marble for interior decorations. 



The black Trenton limestone of Glens Falls was also quarried 

 by one firm, Finch, Pruyn & Co. and sold in rough state for 



building stone. 



Production of marble 



Sandstone 

 Sandstone is more widely distributed over the State than any 

 other stone. Many large areas underlain by good sandstones, how- 

 ever, are not worked at present, because of the abundant supply of 

 better stone which can be cheaply obtained from the more exten- 

 sively developed areas. In western New York to the south of 

 Lake Ontario an extensive quarrying industry is carried on in the 

 Medina sandstone, the operations being confined mainly to Orleans 

 county. This stone is a medium grained, usually red stone, although 

 some white stone has been extracted. It has been used in a number 

 of important buildings and forms a beautiful and durable stone. It 

 has also a wide use in street work as paving blocks and curbing. 

 Quarries in the Medina formation have also been worked in Niag- 

 ara, Monroe, Wayne and Oswego counties. In the northern .\di- 

 rondack region, in Jefferson, St Lawrence and Franklin counties, 

 a large amount of sandstone of Potsdam age has been quarried 

 both as building stone and as flagging. The stone varies from pink 

 to gray and from a firm hard quartzite to a friable sandstone,^ The 

 main production at present comes from the vicinity of Burke in 

 Franklin county and consists chiefly of flagging, which is shipped 

 to Montreal and other Canadian cities.
