60 Report on Building Stone of New York. 



The stripping of drift- earth and some imbedded angular masses of 

 sandstone is thin. The stone of this quarry has a light red color, and 

 is fine-grained. It is worked into paving blocks * and into building 

 material. A side track at the quarry affords convenient facilities for 

 loading directly from the quarry. 



The quarry of Timothy O'Brien is three-quarters of a mile east of 

 the Holley station, and on the south side of the railroad track, and also 

 of the Erie canal. It was opened in 1881. About three acres has 

 here been worked over. The stripping consists of drift earth, largely 

 made up of fragments and masses of broken sandstone. The beds 

 of stone here, as in the Gorman & Slack quarry, are horizontal. A 

 marked feature is a system of joints, which runs east and west, and 

 dips steeply north, and 15 to 20 feet apart. A second system, 

 not so commonly observed, runs south, and in a more irregular 

 course and dip. The total thickness of the rock quarried ranges from 

 7 to 15 feet, and the bottom rock is a coarse-granular, dark-brown 

 sandstone, which is very hard and breaks hackly. Underneath this 

 bottom rock is a red sandstone bed known as u red horse." The 

 quarry water has to be raised four feet to the level of the out- 

 flowing ditches which carry it off north to the canal. The product 

 is mainly paving blocks, with some stone for building purposes. 

 The stone is sold in the rough for crosswalks, curbing and general 

 building work. Much of it goes to Rochester ; some to Buffalo. A 

 large force of men is here employed for about seven months in the 

 year, or until the beginning of freezing weather. 



One mile south of Holley an old quarry, known as the 4< cider 

 mill quarry," has been reopened the past season by Hiram Joslyn, of 

 Holley. 



Hulberton, Orleans County. — The Hulberton group of quarries 

 are located on the north side of, and close to the Erie canal. Begin- 

 ning at the east, the first opening is that of Sturaker & Sullivan. 

 This quarry was first opened in 1884. The stripping on the stone 

 consists of earth and broken stone, a few feet thick. The workable 

 beds together are 10 feet thick, and at the bottom is a dark, brownish- 

 red, coarse-granular sandstone. The quarry runs about 250 feet in 

 length, parallel to the canal. One system of joints runs east and 

 west, vertically. The others run in an irregular course. Some of the 

 beds are obliquely laminated, and at the bottom, on the east side, 



*The paving blocks made in these quarries are, iii pail, sold with the product of 

 the Albion quarries, and are known as Medina paving blocks.
