 0* At the top of the High point cliff there is 27 feet 37=722 



of Pentamerus limestone, and a little to the 

 south 10 feet more is shown. This limestone 

 forms the top of the terrace, which extends 

 nearly one mile to the south of the cliff before 

 the shaly limestone is reached, but, on account 

 of the heavy dip, it is not possible to give its 

 entire thickness. 

 (C 5 On the partly covered slope south and west of the Penta- 

 merus terrace are occasional ledges of the thicker layers of the 

 shaly limestone and outcrops of the very much weathered and 



decomposed calcareous shales. These shales contain abundant 

 fossils, and frequently on the surface of the slope many nearly 

 perfect shells may be found. A hasty collection from such an 

 exposure gave the following species:
