the thickness usually assigned to the Clinton in its southeastern 
exposures. 
Rocky Fork.—On the pike leading to Belfast, one and a-half 
miles from Hillsborough. At the bridge, on the south side of 
the stream, the top of the Clinton is shown, underlying the Day- 
ton limestone. East of the bridge, the east bank of the stream 
gives good exposures. Only a hasty observation was made. 
The fossils found, such as Orthis elegantula, were not conclu- 
sive. The strongly ferruginous character of the rock, especially 
an o6litic iron layer thinly interstratified at one place, in connec- 
tion with its position beneath the Dayton limestone, sufficiently 
identified it. The writer failed to trace the Clinton eastward 
along Rocky Fork, but on the contrary found evidence of chert 
beds belonging to horizons quite a distance above Dayton lime- 
stone, at the lowest exposures next seen on going up stream. 
In this chert Encrinurus ornatus, Hall, was well shown in one 
case. An associated rock contained abundant Meristellas, much 
shorter than Meristella cylindrica, as seen in full-sized cabinet 
specimens from Hillsborough. Bisher’s dam is only a short dis- 
tance down stream from the bridge, and no very good reason can 
be seen there why the Clinton should not continue to be exposed 
for some distance down the stream. Unfortunately the writer 
had not the time to search in this direction. 
Belfast—Thirty-four miles southeast of the Todd’s Fork 
locality, and 17 miles southeast of Sharpsville. 
I. The Wilham Haigh Farm section —Going north along the 
road through Belfast, about half a mile from the center of the 
village, and then taking the first road going westward, a little 
stream, crossing the road, is soon reached. Following this 
stream southward, the Dayton limestone is found exposed in the 
creek bed, within a short distance of the road (locality 10). 
Continuing down stream the following very characteristic section 
is exposed. Beneath the Dayton limestone is the ferruginous 
crinoidal Clinton, containing Lepteena rhomboidalis, Phanopora 
multifida, and Rhinopora verrucosa. Within 200 feet of the 
road the ferruginous layer is conglomeritic, the pebbles being
