REPORT OF THE STATE PALEONTOLOGIST I9O3 353 



at Napanoch. The presence here of Leptaenisca adnas- 

 c e n s Hall & Clarke is indicative of the New Scotland age of 

 these beds. 



In passing northward from Ellenville the first outcrop favor- 

 able for the examination of the Cobleskill is on the land of 

 Joseph Chipp ^ mile north from Kerhonkson. The rock is 

 shown in the base of an old quarry on the left of the highway- 

 leading to Accord. The locality is not favorable for collecting 

 but the following fossils were obtained.

cedens Schuchert 



2 Atr5'pa reticularis Lmw^ 



3 Orthothetes interstriatus Hall 



4 Spirifer corallinensis Grahau

The Rondout is not well shown in this section. About i6 

 feet of Manlius limestone is exposed in the quarry of Lincoln 

 McConnell on the opposite side of the highway. The combined 

 thickness of the Rondout and Manlius at this place is 70 feet. 



One of the most favorable localities for the examination of 

 the Decker Ferry and Cobleskill formations is in the cut of the 

 recently constructed Kingston branch of the Ontario & Western 

 Railroad, ^ mile southwest from Accord. The railroad passes 

 in succession over the formations, from the shales underlying 

 the Decker Ferry to the Coeymans limestone which is exposed 

 near the station at Accord, but only the shales, the Decker Ferry 

 and the Cobleskill are shown in the cut. The shales which are 

 exposed in this cut are considered to be of Salina age and are 

 exposed for a thickness of 18 feet. The beds are soft, argillace- 

 ous with bands of mineral matter and so far as known without fossils. 



The Decker Ferry formation is 12 feet thick and in layers 

 which are quite massive. The basal layer is arenaceous and 

 gradually changes and becomes more calcareous above. The 

 formation is fossiliferous throughout. The red crystalline lime- 

 stone which forms such a conspicuous layer in the Nearpass sec- 

 tion has not been observed here, and whether its absence is due 

 to thinning out or failing through overlap of the succeeding 

 deposits, in which case only the upper part of the Decker Ferry
