ton, but now inhabited by E. D. Miars. Nearly opposite, but a 
little down stream, a few stray pebbles were found in the Clinton. 
In order to satisfy myself that I was dealing with genuine 
pebbles and not with concretions, accidental layers of peculiar 
character, or rolled stromatoporoids, it was necessary to break 
open most of these. But on the south side of the stream occur 
two pebbles whose character would be acknowledged by any 
geologist, the larger one being 7% inches long, 534 inches broad, 
and 1¥% inches thick. Since the chief value of these pebbles 
lies in the fact that they are zm sztu, they were indicated by a 
mark pointing towards them, and it is hoped the pebbles will 
not be removed by visiting geologists. Pebbles were very scarce 
in the Clinton, only about six pebbles were found whose character 
was unequivocal. They were evidently derived from the Clinton 
layers immediately beneath. Following the stream southwards, 
nothing of special interest occurs until we reach the well-known 
Todd’s Fork section, described in an earlier paper. It is on the 
north side of the stream, about three hundred feet east of the 
bridge, by which the Quaker Centre pike crosses the fork. Here 
the terruginous, red-brown, odlitic, fossiliferous Clinton is well 
developed at the top of the section, these characters disappear- 
ing on going downward in the section, so that six feet below the 
top the rock is pinkish in color and has but few fossils. The 
Clinton section is here 18 feet. The lower two-thirds is light 
pink in color, and contains few recognizable fossils, although on 
closer examination the rock is seen to be a mass of crinoidal 
fragments, consisting especially of pieces of the narrow stem of 
some crinoid. Associated with the ferruginous layer is some of 
the purple tinted rock already mentioned. In it was founda 
thin pebble, consisting of the iron-stained limestone found imme- 
diately below. Allof the pebbles found in the Clinton of Todd’s © 
Fork resemble the Clinton rock lithologically. In the pinkish 
rock, forming the lower two-thirds of the Clinton, evidences of 
stratification are in places rather common; at a few places a sort 
of cross-bedding was noticed. This can be seen at the Todd’s 
Fork section just mentioned, and also up stream a short distance
