936 GEOLOGY OF OHIO. 
EK. AMES LIMESTONE, 
Two analyses of this excellent limestone are given. The first sample 
was taken from the stock pile of Ogden Furnace, and the second from the 
outcrop of the stratum on the land of L. D. Linscott, Trimble township, 
Athens county. The analyses fairly represent this stratum. It is cer- 
tainly the purest in composition of the limestones of the Hocking Valley: .

F. CORNIFEROUS LIMESTONE. 
Two analyses of the Columbus or Corniferous Limestone are introduced 
here. Thesamples were both taken from Smith and Price’s quarries, two 
miles west of the city, and from the particular course called the “smooth 
rock.” The first analysis represents the best grade of the limestone, 
and shows this variety to be equal in purity to any limestone of the 
State. The second sample represents courses that lie at a lower level in 
the quarry: 
“smooth rock.” 
Same quarries, but lower 
layer.
