Washington county 1 

 The limestone areas of this county, though not extensive, 

 include some of the purest linn found in the state. One 



narrow belt extends from Middlefalls to North Argyle, a second 

 :.• Adamsville and extends northward past the eastern 

 Ann and Whitehall to the Vermont boundary. A 

 tlnr lies on the boundary between New York and Vermont 



I along the Rutland branch of the Delaware and Hudson rail- 

 L The rock has been extensively quarried at Smiths Basin 

 of Fair Haven. 

 At Smiths Basin the Keenan lime company has several quar- 

 ries in the ridge to the east of the railroad. The rock is mostly 

 dark gray to bluish black, fine grained and moderately hard. Its 

 massive character has been somewhat destroyed in places by the 

 shearing and folding to which the rock has been subjected, and 

 the upper beds are shaly and silicious, still the lower ones are 

 very pure. The company has four limekilns of continuous type. 

 !M~iich of the rock has also been shipped to Troy both for use as 

 a flux in blast furnaces and also for lime in Bessemer converters. 

 The following analyses will serve well to show the composition 

 of the stone.
