THE MINING AND QUARRY INDUSTRY I9II 



8; 



Gouverneur Marble Co., St Lawrence Marble Quarries, J. C. Cal-. 

 lahan & Sons, and the Northern New York Marble Co. 



The belt of metamorphosed limestones which extends from 

 Columbia county through Dutchess and Westchester to Manhattan 

 island contains in places a good grade of white and gray marble. 

 Quarries have been worked in the past at Ossining, Dobbs Ferry, 

 White Plains, Pleasantville, Tuckahoe, Greenport, and other places. 

 Tuckahoe has been a notable locality for white marble used in the 

 buildings of New York City. At present the only active quarries 

 worked for building stone are at South Dover. The South Dover 

 Marble Co. has been the chief producer of late years and has sup- 

 plied material for many of the large structures in New York, 

 Washington and other cities. The Dover White Marble Co. has 

 recently worked quarries in the same vicinity. The stone from this 

 locality possesses uniformity of grain and color and is undoubtedly 

 one of the best white marbles in this county. 



A mottled pink and gray marble suitable for interior decorations 

 is obtained from the Chazy formation at Plattsburg. The quarries 

 recently operated by the Rutland-Florence Marble Co. have been 

 acquired by the \^ermont Marble Co. 



Black marble — a fine-grained, compact, black variety of the 

 Trenton limestone — is quarried for ornamental purposes at Glens 

 Falls by Finch, Pruyn & Co. who ship the stone mainly in the 

 rough state. 



The production of marble in the State last year was valued at 

 $278,041, an amount considerably below that reported in any other 

 recent year. The value of the output in 1910 was $341,880. In 

 1908 it was $692,851 or more than double the output last year. 

 The falling off, as shown in the accompanying table, has been 

 mainly in the marble used for building purposes.
