236 BULLETIN OF THE NEW YORK STATE MUSEUM 



Sixth avenue and Thirty-second street, New York city ; 

 also the M. E. church in Sing Sing. 



Hastings, Westchester County. — The marble quarries near 

 Hastings produce a white, fine-crystalline, dolomitic stone. 

 They have been idle for many years. 



Sing Sing, Westchester County. — The crystalline limestone 

 east of the state prison and on the state property was for- 

 merly worked for marble ; and the prison buildings, and the 

 State Hall at Albany are built of stone which came from 

 these quarries. 



White limestone in the Dover Plains — Patterson valley, 

 has been opened at several points between Patterson on the 

 south and Dover Plains on the north, and a white marble 

 has been obtained and worked up largely for monumental 

 bases and grave-stones. The stone of these quarries is 

 bluish-white and fine-crystalline in texture and is readily 

 dressed. They have been idle for several years past. 



Towner's Four Corners, Putnam County. — The old quarry 

 at this locality was opened two years ago for stone to be used 

 in the construction of the Sodom dam. The stone is gray 

 and white, rather coarse-crystalline and contains many crys- 

 tals of white pyroxene scattered through the mass. The 

 friable and decomposed condition of the ledges near the 

 quarry leads to the belief that the stone is not very 

 durable. 



Gouverneur, St. Lawrence County. — At Gouverneur there 

 are three companies working marble quarries. The works 

 and quarries are located about one mile south-west of the 

 village and near the R., W. & O. R. R. line. There are 

 two leading varieties of stone obtained in these quarries ; 

 a light gray, at the top, and a dark blue, at the bottom. 

 The latter resembles, when dressed, some of the gray gran- 

 ites. Both varieties are coarse-crystalline in structure. A 

 specimen from the St. Lawrence Marble Company's quarry 

 was found to have a specific gravity of 2.756, equivalent to
