XVIII J)' 2 . A little farther up the creek are falls, some twenty feet 

 high, and a gorge, the sides of which are thirty feet or more in height. These 

 shales are much coarser than those of I) 1 , and contain fossils of large size, as 

 Spirifer grcmulosus (Con.), Hall, and large Lamellibranchs are common. 

 Alternating with the coarse arenaceous shales are somewhat calcareous layers 

 and these thick strata form the falls. The following species were collected:

The lithologic appearance of these, shales agrees w ith that of the upper 

 Hamilton formation while the fauna is distinctively Hamilton, so that these 

 shales unquestionably belong t<> the Hamilton formation.
