tercalated between them is a somewhat shaly layer with abundant 

 corals. 



Schoharie creek sections. On the west side of Schoharie creek, 

 besides the well known exposure south of the creek bridge, the 

 Cobleskill is exposed at Clark's cave, % m ^ e north of the bridge. 

 At this point the Lorraine shales are well shown, and the contact 

 with the Salina shales can be seen. There is another exposure of 

 the Cobleskill on the east side of West mountain, at the stronti- 

 anite mine 1 mile north of Clark's cave. Farther along on the 

 northeast point of the mountain the rock is shaly. and collecting 

 is good. Still farther along, nearly opposite Central Bridge, there 

 is a similar exposure with fossils. From this point to Howes 

 Cave there are no good exposures on the mountain side, and the 

 dip soon brings it below the surface when a lower level is reached. 



Howes Cace. The Howes Cave section is well known, and 

 from this point the formation is somewhat obscured for some 

 distance to the north, but. at a point 1 mile below and V2 m il e 

 from the highway leading to Central Bridge, there is exposed in 

 the creek bed the Cobleskill together with the Salina shales 

 and the Lorraine beneath. This section is one of the best 

 at which to observe the contact between the different formations. 

 Beyond this station and nearly west of Central Bridge, on the 

 farm of Mr Tarr. there occur very large boulders of Cobleskill 

 arranged in nearly a straight line, from which corals may be had 

 in large numbers. A mile and a half farther north from this 

 point the limestone outcrops by the roadside at the house of 

 Eugene Maxwell. The overlying rock has been removed by 

 erosion, and considerable of the upper surface of the Cobleskill 

 is exposed at this point, and on the read to Grovenor's Corners, 

 where frequent exposures are seen, specially near the house on the 

 Judson Grovenor farm and at several points on the farm of 

 Sol Dewey. 



Grovenor s Corners. At Grovenor's Corners there is a fine ex- 

 posure, and this outcrop continues at intervals for nearly a mile 

 on the road to Carlisle. 



Carlisle. One mile northwest of Carlisle is the last good 

 exposure of the Cobleskill on the way to Sharon Springs, but 

 there are several points where its presence can be detected and
