quarry is equipped with liand derrick and siphon. Three men 

 are employed throughout the year. The product is chiefly flag- 

 stone, which is sold to the Ulster bluestone co. at Maiden. 



Con Harvey, Quarryville. This quarry is south of the preced- 

 ing. The bed of stone is 10 feet thick, with an overburden of 

 20 to 30 feet, 15 feet of which is rock, the balance clay. The 

 stone is of the best blue color, fine grained and full of reeds, 

 which will not weather open if stone is split to 20" to 24'' 

 thickness. No heads are found in this quarry, but the Side 

 seams are very regular, 3 to 9 feet apart. 



The top part of this bed is grayer and harder than the lower 

 lifts, which are soft and blue. All the stone, however, works 

 well in the mill. The product is almost entirely " rock." Four 

 to five men are employed all the year. The equipment con- 

 sists of a steam pump to handle the rain water, and that issuing 

 from springs in the quarrj^ Some very large stones have been 

 taken from the quarry, one slab being 9 inches thick and 17 feet 

 by 16 feet in area. 



Alfonso Carnright, Quarryville. This quarry is on the same 

 ledge as Harvey's and just south of it. The bed of stone is the 

 same, but the top is 35 feet thick. The gray sandstone noted 

 under Sterrett's quarry shows here in the top. These two 

 quarries are known as the " Michigan " quarries. The ledge is 

 owned by the Ulster bluestone co. of Maiden, which buys all 

 the stone. There is only one lift in the bed, but the reeds are so 

 frequent that the stone is easily split. 



These quarries were very valuable at one time and have pro- 

 duced a large amount of stone, but now the top is very heavy 

 for the bed, and only skilful quarrying makes it possible to oper- 

 ate them profitably. 



The rock is hauled 4 miles to Maiden at a cost of 20^ of the 

 value of each load. The prices paid vary from 3c to 5c an inch 

 of thickness per square foot. Carnright employs four or five 

 men throughout the year. 



South of and below the Michigan ledge is the Quarryville 

 ledge, which has been opened for over a mile in a north and 

 south direction. This was the great ledge of the district at one
