and one on the left bank of the outlet. The latter quarry is 

 that of the Jamestown shale paving brick co. This quarry was 

 originally opened for building stone, but the amount of shale 

 became so great that the brick works were built to dispose of 

 it. Now the quarrying of the stone for building is a minor 

 affair. The ledge opened is 62 feet thick. The upper 25 feet 

 are of shale and thin layers of stone, all of which is used for 

 making brick. Below occurs the stone for building purposes. 

 The stone is bluish, fine grained, and hard. The vertical joints 

 are at irregular distances apart. 



The systems run n. 30 w. and s. 55 w., the first being vertical, 

 the second pitching steeply to the northwest. The lifts vary 

 from 6'' to 14''. The product includes common building stone 

 and cut work. It is sold in Jamestown for |6 to |7 a coTd. 



The quarries on the right bank of the outlet are at irregular 

 intervals, the distance from the first to the last being about 

 f of a mile. They have been worked extensively at one time, 

 but are small producers now. The maximum hight of face 

 exposed is 65 feet. Below the top 5 feet of earth, stone and 

 shale are interbedded. The upper courses produce only com- 

 mon building stone, while the lower beds are thicker, of better 

 color and grain, and are cut for house trimmings for local 

 market. No machinery of any kind is in use, but three of the 

 openings are provided with hand derricks. 



Watts Flats, Chautauqua co. 



No quarries are in operation here. 



North Clymer, Chautauqua co. 



Two quarries on the same ledge have been worked J mile 

 east of the railroad station. The bed of stone is 20 feet thick, 

 but the top 4 feet are too rough for good stone. Above the 

 bed are 3 feet of earth. The lifts vary from 1 foot to 3J feet. 

 The bed dips gently to the northeast. The stone is light gray 

 and fine grained, and liable to weather badlj^ The quarries are 

 owned by P. J. Keed and B. P. Smith, but have not been worked 

 for three seasons. 



This stone has been used for bridge abutments in Buffalo and 

 on the Buffalo, Rochester and Pittsburg railroad.
