their greater accessibility, it has come to pass in all of the larger quarries 
that the supply of the first variety is much more limited than formerly. 
The blue stone when laid in masonry undergoes a change of color in its 
exposed portions similar in kind to that which the outer portions of the 
native beds have already passed through. 
There is also in the Waverly system a large amount of stone of a yel- 
lowish cast, which deepens by exposure ; but this, though equally durable 
is less sought for the better class of buildings. y 
On the western side of the county especially, though not strictly con- 
fined to this region, these same courses are beautifully variegated with 
bands of red, yellow, and brown. This variety is shown in its best state 
near Cynthiana, and whenever railroad transportation shall be furnished 
to this region, it may be counted certain that the admirable qualities of 
this, stone will be in demand for ornamental architecture. This varie- 
gated sandstone happens to have a constitution that fits it for use as 
erindstones, for which it is in considerable local demand. 
There is also in the same locality, viz., near Cynthiana, a very white 
and fine-grained representative of the quarry courses, which, among 
other uses, has been in limited demand for gravestones. The whiteness 
of the stone has more than once suggested it as a glass-making rock, but 
the subjoined analysis shows that the property in question is due to the 
absence of oxides of iron, and that in reality the sandstone is not of the 
highest degree of purity. ! 
The specimen in question was taken from the quarries of John Traber, 
Hsq., on the western edge of Shepherd’s Mountain :

The principal defects which the Waverly stone exhibits in its applica- 
tion as a building stone are the following: 
a. Some varieties of it are too tender for the uses to which they are 
put. For the exposed courses of buildings, for steps, or flaggings, such 
varieties are ill adapted. | 
b. Many representatives of the Waverly stone are unable to endure 
_ the action of the atmosphore. When exposed to the weather a process © 
of exfoliation begins, which, though it advances very slowly, results in 
the destruction of the stone.
