Two large quarries (60, 61) in the Stoekbridge limestone have 



long been worked near Ossining, part of the product being 



shipped for use as flux and part being burned into lime. These 



quarries are worked by Henry Marks and the Sing Sing lime 



CO., respectively. Analyses^ of the rock follow.

Oscawana, Westchester co. Tat's quarry (65) is located about 2 

 miles northeast of Oscawana station. Very little stone has 

 been taken out and the opening is not at present worked. The 

 product is a very white and very fine grained marble. The 

 quarry could not be closely examined when visited, as the open- 

 ing was filled with water, but if blocks of large size can be ob- 

 tained the product should be readily marketable, as the quality 

 is excellent, so far as color and grain are concerned. 



Bedford, Westchester co. Several small quarries (62) east and 

 northeast of Bedford in the Stoekbridge limestone, were for- 

 merly w^orked, the product being burned into lime for local use. 



Armonk, Westchester co. Quarries just north of the Connecti- 

 cut line were formerly worked rather extensively, all the pro- 

 duct being burned into lime. 



Golden's Bridge, Westchester co. Todd's quarry (64) is situated 

 about 3 miles east of Golden's bridge. It is a small quarry, in 

 a rather highly contorted limestone, and has not been worked 

 for the past 10 years. The stone does not appear to be fit for 

 cutting, though a mill is located near the opening. 



Marble has been quarried at Patterson and Towners (66), Put- 

 nam CO.; but the product was not large and the quarries have 

 been idle for some years.
