known as bluestone and though the term, in its original significance, 

 referred to the Ulster county stone, it is now generally used in a 

 much broader sense. 



In eastern New York, the Devonic rocks involved in the sand- 

 stone area are represented by beds of coarse sedimentation, quite 

 uniform in lithologic features, extending from the Hamilton to 

 the Catskill, and quarries are operated in all the formations. In 

 passing westward into central and western New York, the Hamil- 

 ton is represented mostly by shales with a few beds of limestone.. 

 In the eastern section a large number of quarries have been opened 

 in southern Greene and the northern portion of Ulster counties. 

 These quarries are located but a short distance west of the Hudson 

 river. Most of the product is shipped by water from Catskill, 

 Greene co. and Saugerties and Kingston, Ulster co. Another im- 

 portant district comprises Sullivan, Delaware and Broome coun- 

 ties,- and the chief shipping points are Walton, Hancock, Lordville, 

 Hale Eddy and Fishs Eddy, Delaware co. ; Rockland, Livingston 

 Manor and Long Eddy, Sullivan co. ; and Deposit, Broome co. 

 The product is shipped mostly by the Erie and the Ontario & 

 Western Railroads. 



In central and western New York, the bluestone quarries are 

 confined to the Portage and Chemung groups, with the most im- 

 portant ones in the Portage. 



The quarries along Cayuga and Seneca lakes are in the Cashaqua 

 division of the Portage, and include a line of quarries extending 

 . from Ovid Center to Taughannock Falls. The quarries at Ithaca 

 are in the Ithaca formation and those around Norwich are of the 

 same horizon. The quarries in the vicinity of Warsaw in Wyoming 

 county are in the High Point sandstone, a still higher division of 

 the Portage. To this same horizon belong the quarries just east of 

 Elmira, Horseheads and at Pine Valley. In western New York a 

 number of quarries have been opened in the Chemung formation 

 and include those to the south of Elmira and most of the quarries 

 in Allegany, Cattaraugus and Chautauqua counties. 



Production of sandstone 



The total value of the sandstone quarried in New York last year 

 was $2,043,960. This is an increase of $147,263 over 1904. The 

 output was distributed among 35 counties with an aggregate of over 

 400 producers. Classified as to uses the total was distributed as 

 follows: building stone, rough, $279,72$ ; building stone, dressed, 

 $250,757; curbing, $543,002; flagging, $486,911; paving blocks,
