QUARTZYTES AND SANDSTONES. 63 



The Goodrich & Clark Stone Company's quarry- is the next 

 one, £oing eastward, and is about half way between the canal and the 

 railroad. It was opened three years ago. The excavation is about 

 350 feet long, from east to west, and 300 feet wide. The stripping 

 consists of sandy earth, from 3 to 10 feet thick, and imbedded in it there 

 is some broken stone. This quarry has been worked to a depth of 

 about 18 feet. The beds dip to the south at a very low angle. The 

 joints run east and west generally or south 85° west, and are from 12 

 30 feet apart. A second system runs north and south, and dips 

 steeply eastward. At the south side the beds are thin. On the north 

 they are thicker, up to four feet. The stone is red in color, fine-grained r 

 with some greenish-grey laminae on the bedding planes, or what may 

 be termed sap edges. They are usually less than a quarter of an inch 

 thick. Some of the beds show a striped, laminated structure. Some 

 are marked by cross bedding, while others are entirely homogeneous in 

 texture. The stone can be split readily in planes parallel to the bed- 

 ding. The upper sides are generally smooth, true and faintly 

 lined as if wind had drifted sand over the original surfaces. And 

 these surfaces are good for platforms and flagging-stone. The water 

 of the quarry passes into a sewer at the bottom of the quarry, and 

 goes north under the canal. Some of the stone is sold for common 

 rubble work. A part of the inferior or poorer grade is split into 

 paving blocks ; the best is used for building stone or paving blocks. 

 The stone is carted to the canal and shipped by boat to destination. 



Albion Stone Company's Quarry. — This property embraces 

 the old Sickles quarry, and what is known as the Sullivan quarry. 

 It was first opened thirty years ago. The present company has 

 connected these quarries by its working ; and the present exca- 

 vation is now nearly 2,000 feet long, from east to west. At the west 

 end the quarry has advanced quite to the railroad line. The total 

 area worked over is approximately estimated at eight acres. The 

 stripping at the west end consists of earth and thin, shaly rock, having 

 a thickness of 10 feet. Eastward the shale disappears, and the earth 

 alone averages 10 feet thick. It is of a red, sandy nature, and is 

 readily removed. On the west this quarry approaches within a few 

 rods the east line of the Goodrich & Clark Company's quarry, but it 

 extends much further to the south. The beds vary in thickness, 

 thinning out wedge-like, as others come in to replace them. So also 

 the stone varies in character from point to point, even in the same
