at Falling Spring. They are some of the largest in the 

 county. The beds from which the lime is obtained are the 

 lower beds of the limestone shale in No. VI. These beds 

 are almost barren except the coral bed which is as largely 

 developed here as at Garber' s quarry and the corals are more 

 silicified. They occur in the highest bed in the quarry, and 

 good specimens may be obtained from a small hole in the 

 field to the southeast. 



The Oriskany sandstone (VII) crops out at the turn of the 

 road north of the quarry and again on the other side of the 

 field belonging to John Berry. Between these two lies a 

 tongue of the Devonian slates and the Marcellus ore. See 

 Plate XI, page 158, Fig. 2. 



These two lines of Oriskany sandstone come from the 

 road from New Bloomfield to Rattlesnake hill, returning 

 rom Ayl's lime quarry and the camp ground. 



Smith' 's quarry and red ochre diggings. 



At this point is shown the meeting of three different 

 groups : — Marcellus limestone and lower ore ; Oriskany 

 sandstone ; and Lower Helderberg limestone. 



In the quarry occur the Coralline beds of the sandstone 

 shales, with Trematopoia, dipping southtoest, and a few 

 yards further up the road northeast. Between the quarry 

 and the corner of the road maybe found in the bank traces 

 of the Meristella bed, but not well exposed. 



The Oriskany betrays itself almost exactly at the turn in 

 the road, and following it is a bed of red iron ochre from 

 which many tons have been taken and ground down for paint, 

 which is said to be of good quality. The seam varies from 

 one to three feet in thickness and has been followed along 

 the crop for about 80 or 100 feet, but no attempt is now 

 made to mine it. 



Next to this is a feeble show of the Marcellus limestone. 

 In the field below some of this which has been thrown out 

 from a small tunnel run about 25 feet in the search for ore. 



Oriskany sandstone; Marcellus andLower Hamilton shales. 



These beds require little notice. They make no con-
