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 Gard’s 
quarries. The following is a list representing the grand divisions, 
Brachiopoda, Gasteropeda, Cephalopoda, Crustacea and Corals, found at 
Gard’s, near Greenville:
