Section D 



This section begins 15 rods northeast of section C, or 34 rods 

 northeast of Pflaum's spring in the large Bennett quarry. 



Di Dense, compact, dark blue almost black limestone. A finely 

 grained variety alternates with one rather coarsely grained in beds

Section D 



from I to 6 inches thick, separated by almost black shale seams; 

 these latter vary in thickness from a fraction of an inch to an inch 

 and are very irregular ; the thinner ones at times even present an 

 appearance similar to cranial sutures. The thicker ones are not so 

 irregular but are rather as though molded over little hillocks. These 

 shale seams are often separated from the rock above and below by 

 calcite seams, the crystallization of which is vertical to the bedding 

 plane; at times even the laminae of the shale are farther separated 

 thus. There are quite coarsely grained layers, specially toward the 

 upper part of this locality; these are usually only i to 3 inches in 

 thickness ; the last one of these occurs about 2 feet below the base of 



the Favosites bed 20 feet 



The following is a more detailed subdivision of the above from, 

 the 1)ase upward.
