It is remarkable, too, to notice the difference in paleontological condi- 

 tions between the two principal quarries, Gard's and Bierley's. The 

 former contains a considerable number of genera belonging to five or six 

 classes; the latter many genera and species, but all representatives of one 

 class, viz., crinoidea, which has not a single representative at Grard's 

 quarries. The following is a list representing the grand divisions, 

 .Brachiopoda, Gasteropoda, Cephalopoda, Crustacea and Corals, found afc 

 Gard's, near Greenville:
