K35 Dense blue limestone with two small chert bands, each in 



the lower portion of a very fossiliferous layer. The fossils are 



almost wholly specimens of Spirifer mnrchisoni Castel- 



nau. Upper Oriskany 3^ feet 



K36 Strata concealed. Upper Oriskany 8 feet 



K37 Dense, blue limestone. Upper Oriskany 2^^ feet 



K38 Dense blue limestone, exceedingly fossiliferous. Upper 



Oriskany 6 inches

K40 Blue limestone. The middle and upper parts are specially 

 fossiliferous. Tentaculites elongatus Hall is by far the 

 most noticeable fossil here. Upper Oriskany 2 feet

K41 Esopus strata including the portion covered by the swamp 

 between the Oriskany and the Esopus 550 feet 



The gross structure of the Esopus is shown in figure 7. 



K42 A dark arenaceous shale, cleaving into slate pencillike 

 pieces. Fossils, owing to the great development of cleavage, are 

 exceedingly rare. The only species identified was Coelospira 

 acutiplicata (Conrad) , several specimens of which were 

 found. This fossil-bearing horizon represents merely an inch or two 

 of rock on the uppermost surface of the Esopus ; for when followed 

 southeastward, not a single fossil could be found though prolonged 

 search was made for that purpose. Onondaga 1-2 inches 



K43 The 29 feet of strata which are concealed beneath the Erie 

 Railroad here outcrop almost a quarter of a mile to the southwest 

 along the eastern side of the railroad tracks. The only fossil identi-
