pretty rapidly from Cincinnati Furnace to Raysville (77 feet), and the
rocks dip in the opposite direction; hence there may be more than one
hundred and fifty feet of these rocks. In the fine grained blue Waverly
sandstone at the base of the conglomerate group, I find Producta semireticulata, Orthis Michelini, Rhynchonella Sageriana, a Myalina, and several
other undetermined species of fossils. The lower fifty feet of the conglomerate group, or more properly beds of passage, greatly resemble the
fifty feet seen in a cut on the Columbus and Hocking Valley Railroad, on
the farm of James Francisco, Marion township, Hocking county, of which
I give a section elsewhere.
In passing from the coal measures in Hocking county down to the
Waverly, we find in place of the coarser rocks at Cincinnati Furnace, a
group of comparatively fine grained buff colored sandstone, one hundred
and thirty-three and a half feet thick. These rocks contain marine
plants, Syirophyton, cauda-galli, &c.; Producta, 3 species; Rhynchonella,
Orthis, &c. Below this group which I have called, for convenience of
designation, the Logan Sandstone, are eighty-five feet of alternate fine
grained Waverly-like seams and conglomerate. The fine grained sandstone is often blue and rich in fucoids after the manner of the Ohio river
Waverly. Beside the marine plants are Producta; Chonetes; Syringothyris,
typa; Orthis, &c. Below this conglomerate group we find the coarse
sandstone and conglomerate which form the chief Waverly in the hills in
the Hocking Valley. The Waverly is found to be entirely changed in its
lithological character. It is always coarse with the single exception of
twelve feet of fine grained rock seen at the base of the hills near Sugar
Grove, Fairfield county. Often it contains pebbles of the size of a hickory nut. At Mount Pleasant, a bold hill near Lancaster, some two hundred feet high (by estimate), there is a bluff exposure on the south-western side. The rock here varies in no respect from a common coal measure
conglomerate. It ranges all the way from a hard compact sandstone to a
coarse conglomerate filled with quartz pebbles. In color it ranges from
white through various shades of yellow to dark ochre and even to lively
brick red. Generally, however, it is a coarse yellow loose grained sandrock.
There is much false bedding, and an exact section would be impossible.
In many places the face of the cliff presents a curiously honey-combed
appearance from unequal disintegration by weathering. The typical
Waverly look was nowhere seen. If a layer of fine grained Waverlylike stone seen between Sugar Grove and the mouth of Clear creek,
continues to the north-west, its place would be in this hill. The Lancaster stone is quarried for building purposes, and the new court house now
in process of erection at Lancaster, is being built of it.
Four miles below Lancaster, in Berne township, the Waverly sandrock
