78 Report on Building Stone of New York. 



from other districts, and not even our best granites, are as strong to 

 resist transverse pressure or strain. Tests (comparative) show that it 

 is fully three times as strong, in this way of resistance, as granite, 

 marble, Ohio sandstone and Connecticut and New Jersey brown- 

 stones. To resist compression it is not much superior to these sand- 

 stones, and not equal to the best granites. And its strength against 

 transverse strains tits it for lintels, sills, caps, and water tables espe- 

 cially. The use for house-trimming material is increasing as com- 

 pared with Avhat is sold for nagging and curbing or for street work. 

 And the mills in the district are increasing their product from year 

 to year. The output of blue-stone in 1887 is estimated at 6,500,000 

 feet.* 



Monroe, Orange Countf. — Quarries for flag-stone are opened 

 on the southern end of Skunnemunk mountain, near the Seven 

 Springs Mountain House, and three miles north-west of Monroe. 

 The strata are thin and lie nearly horizontal. The stone is gray, 

 coarsegrained and rather hard and brittle and there are too many thin 

 beds. The quarries are no longer worked, excepting to meet the 

 occasional wants of the neighboring country. 



Hunter's Land, Schoharie County. — Blue-stone for flagging is 

 quarried at several places in the vicinity of Hunter's Land, south. 

 east and east of Middleburgh. The quarries are in side hills, and the 

 strata lie nearly horizontal, and they are in the Hamilton formation. 

 Their output is carted to Middleburgh, whence it is shipped by rail 

 to Albany, Troy and cities in the eastern States. This group of 

 quarries may be considered as a part of the blue-stone district, 

 although not in the Hudson river belt. The formation is the same, 

 and the stone are similar in appearance and texture, and they are only 

 separated by the narrow divide between the* watersheds of the 

 Mohawk and the Hudson rivers. 



Small quarries for flagging for local uses have been opened at 

 Eminence, a few miles south-west of Middleburgh. 



Oxford, Chenango County. — The quarry of F. G. Clarke & 

 Sons is north-west of Oxford village, on the west side of the Che- 

 nango valley, and at an elevation of 150 feet above the railroad. The 

 rock is covered by from 25 to 30 feet of drift earth, in which are 

 large, imbedded boulders. The opening is on the west side of and
