DESCRIPTIVE NOTES OF QUARRY DISTRICTS AND QUARRIES 235 



Masterton) was found to contain 30.63 percent of lime, and 

 20.77 P^^ cent of magnesia, and 0.91 per cent of Insoluble 

 matter. The specific gravity was 2.868, equivalent to 178 

 pounds per cubic foot. The absorption test Indicated 0.14 

 per cent of water absorbed. The loss In weight when acted 

 upon by sulphuric acid gas amounted to 0.25 per cent. 

 Freezing and thawing produced no apparent change. At 

 a high temperature the specimen was calcined and crumbled 

 at the touch. The Tuckahoe quarries have been worked 

 since 1820, and have produced a large aggregate of marble, 

 which has been put in large and expensive buildings in 

 cities along the Atlantic coast from Boston to New Orleans. 

 It is comparatively durable and resists the action of the 

 weather better than much of the Vermont and the foreign 

 marbles, which have been used in New York city. A 

 noticeable change from long exposure is a slight yellowish 

 shade of color, which can be seen in the U. S. Assay Office 

 building, Wall street, In the building of the National Shoe 

 and Leather Bank, and in the houses of the cardinal and 

 archbishop on Madison avenue. Some of the more promi- 

 nent structures in which Tuckahoe marble has been used 

 are the following : The U. S. Post-office, U. S. Naval 

 Observatory and the Soldiers' Home, Washington. D. C; 

 the City Hall, Brooklyn ; the Stewart buildings on Broad- 

 way and Fifth avenue, New York ; and the Sears building, 

 Vendome Hotel and Revere Bank In Boston."^ 



Pleasantville, Westchester County. — The Snowfiake Mar- 

 ble Company's quarry is one mile south-east of the village 

 of Pleasantville. This marble Is white and very coarse- 

 crystalline. It is much harder than the Vermont marbles 

 and does not compete with them for monumental work. 

 The chemical analysis shows it to be a dolomitic limestone or 

 marble. Examples of its use are : St. Patrick's R. C. Cathe- 

 dral, Fifth avenue, and the Union Dime Savings building, 



* For other examples of Tuckahoe marble see tabular statement in this report of 

 stone used in New York city.
