fossils obtained. But within 3 miles of Sharon Springs no ex- 

 posures have been noted. 



Sharon springs and Cherrij Valley. At Sharon Springs and 

 the section north of Cherry Valley it is clearly evident that there 

 is no limestone between the Lorraine shales and the so called 

 Salina shales above. Westward from Cherry Valley and extend- 

 ing into Herkimer county the Salina shales rest directly on the 

 Clinton formation showing that there can be no Niagara present 

 in this section. 



2 Altamont. In the Helderberg at Altamont. there is a space 

 occupied by an impure limestone which may be referred to the 

 Rondont. This limestone rests on the Lorraine shales. The same 

 condition exists at the Indian Ladder. At South Bethlehem the 

 Rondont is somewhat thicker and it is said would make cement. 

 The contact with the Lorraine shales was seen at this point. 



A short distance south of New Salem there is a thin layer of 

 sandstone lying on the Lorraine shales and below the Rondout. 

 The sandstone contains iron pyrites, and Professor Prosser has 

 provisionally referred it to the Clinton. It may now properly be 

 included in the Rondout. 



Catskill. In the region southwest from Catskill are found 

 the remains of corals and some brachiopods below the Rondout 

 beds, and often the corals are directly on the Lorraine shales, 

 which at this point appear to be conformable with the overlying 

 rocks. South, near West Camp, at the end of a syncline extend- 

 ing from the Catskill region, there is exposed in both limbs of 

 the syncline, about 3 feet of the Wilbur limestone. At this 

 station a number of L e p t a e n a rhomboidalis were 

 found. From West Camp south through Saugerties one can 

 only hope to find the Cobleskill in the limbs of the anticline, 

 which passes from some distance west of West Camp through 

 Saugerties and finally into the Kingston region. The western 

 limb of this syncline was not examined, but the eastern limb 

 in the section about Saugerties is eroded, and only the higher 

 formations can be seen. At Glasco there is a somewhat ob- 

 scure outcrop, but farther south, beyond Lake Katrine and 

 near East Kingston, there is a fine exposure. About 2 feet 

 from the bottom there is a thin layer crowded with A t r y p a 

 reticularis. From this point the limb of the anticline 

 is either obscured by the Champlain clays of the Hudson valley 

 or eroded. At the Newark Lime and Cement Works the Wilbur 

 is shown at several points. Several less important outcrops 

 occur at Wilbur and Eddyville. Outcrops are also found across 

 the Rondout creek opposite Wilbur. These relations hold good
