sometimes preserving their original calcareous shell. Farther 
north, on the east side of the creek, a hole dug in the side of 
the hill (locality 2) showed a more massive and more ferrugi- 
nous rock, many crinoid beads, belonging to the Middle and 
Upper Clinton. No good section is exposed. 
Sharpsville.—Seventeen anda half miles slightly east of south 
of Wilmington, and about three miles a little north of east of 
Lynchburg; in the northwest corner of Highland county. The 
section starts at the east and west road, about two-thirds of at 
mile north of Sharpsville, near the house of Wm. Alexander, 
Nearly opposite the house, on the south side of the road, is a 
quarry opened up into the Dayton limestone (locality 3). The 
base of the Dayton limestone here contains Favosites favosus, 
both the large and small varieties according to Rominger, a 
branching compound coral, crinoid stems, and a few other fos- 
sils, more or less frequently. Immediately under the Dayton 
limestone is found the deep red ferruginous Clinton. This is best 
exposed in the little streamlet southeast of the quarry. Eastward 
along this stream (locality 4) the top of the ferruginous Clinton 
presents a lithological characteristic difficult to describe, except 
that it is a sort of consolidated marl of peculiar color. This 
marl surface contains a number of fossils characteristic of the 
so-called Beavertown marl, overlying the Clinton south of Day- 
ton and also south of the Soldiers’ Home. These are Raphis- 
toma affine, Cyclora alta, Loxonema subulatum? one of the 
small Tellinomyas, Orthis biforata, Orthis elegantula, Orthoceras 
inceptum, and Calymene vogdesi. Of these fossils the Raphis- 
toma and Orthoceras were also found in the ferruginous Clinton 
at Todd’s Fork. The present locality is the most southeastern 
exposure, containing the Beavertown marl fauna, so far known. 
This ferruginous rock is about two feet thick, and is underlaid 
by a pinkish rock containing many crinoid stems, Platyceras 
(Platystoma) niagarense, the small Soldiers’ Home form, and 
Orthis elegantula, corals, and Rhinopora verrucosa. This pink- 
ish Clinton is well shown in the field east of the house of Daniel 
Sharp, along the more southern parts of the streamlet above
