BLUESTONE AND OTHER SANDSTONES 



99 



beds are nearly horizontal and divided by vertical joints, which 

 run north and south and east and west, but are rough and 

 irregular. The product is flag, which is sold locally and also 

 shipped abroad by way of the Erie and Delaware, Lackawanna 

 and Western railroads. 



Dansville, Livingston co. 

 Only one quarry is worked at Dansville, that of Jacob Schub- 

 mehl, which is on the south end of hill which forms the eastern 

 boundary of the valley in which Dansville lies. It is 2\ miles 

 southwest of the town above the Delaware, Lackawanna and 

 Western railroad. The quarry face is 000 feet long, in an east 

 and west direction, and 50 feet high. The top is of shale 15 feet 

 thick, and beneath it shale and stone are interstratified. The 

 stone is light gray and fine grained. In the lower courses the 

 stone has a greenish tinge. The beds average 2-J- feet in thick- 

 ness. There is an abundance of reeds or splitting planes in the 

 stone. The product is chiefly rough foundation work, and the 

 market a local one. 



Hornellsville, Steuben co. 



Two quarries are being worked at Hornellsville. James May's 

 quarry is If miles south of the town on a hillside, 100 feet above 

 the valley. Two openings, 7 rods apart, on the same ledge, are 

 being worked. A vertical section shows 10 feet of clay and 

 broken rock, and 20 feet of stone. The stone is fine grained and 

 bluish gray in color. The bed dips to the southwest gently. The 

 stone is divided by vertical joints running n. 50 e. and s. 40 w. 

 The stone is susceptible to disintegration if quarried during cold 

 weather. The product is chiefly common building stone for local 

 consumption. Two to three men are employed during the year. 



Joseph S. Cobb's quarry is in the same range as May's, and the 

 stone is very similar. The face of the quarry is 900 feet long and 

 50 feet high at the back. There are 8 feet of stripping of clay, 

 25 feet of light blue sandstone (which is used for rough work) and 

 12 feet of blue gray stone. The lower bed is used for cut stone, 

 and the trimmings in the Bryant & Park schoolhouse at Hor- 

 nellsville are from this quarry. As the ledge is worked into the
