Near Cynthiana, where the variegated variety above referred to 
occurs, there is also found a very white, fine-grained variety, and the 
following analysis shows this to be very nearly of the same composition as 
that above, without the oxides of iron:

The Waverly brownstone quarries lie at a horizon about 40 or 50 
feet above the Waverly stone, or Berea grit, in its southward extension. 
They lie very near the horizon of the famous Buena Vista stone of 
Scioto county. A number of the best stone fronts at Columbus, -Ohio, 
have been constructed from the product of these quarries. The stone 
is brown only on the outcrop; when found a few feet under cover it 
assumes a dark blue color and loses its value as an ornamental stone. 
The blue variety contains a large amount of soluble iron protoxide 
which produces a bad discoloration on exposure to the atmosphere. 
The following analysis made by Professor Wormley for the Report on 
the Geological Survey of Ohio shows the composition of the Waverly 
brownstone : :
