CLINTON CONGLOMERATES AND WAVE MARKS. 185 
The first two species named clearly identify the rock from 
which these pebbles were derived as ‘Clinton, a fact already 
manifest from a consideration of the lithological features of the 
pebbles, to those thoroughly acquainted with the Clinton. 
Ellenville section Ellenville lies about four and a half miles 
east of Belfast, farther on along the same road which leads to 
the Elk Run section. In loose boulders of the Clinton good 
specimens of Strophomena patenta, Aspidopora parmula and 
other characteristic Clinton fossils were seen. The section 
here described begins about half a mile south of Ellenville, 
along the east side of the pike, where the Dayton limestone of 
excellent quality with courses 12 inches and more in thickness is 
exposed at several localities, usually east of the culverts where 
streamlets cross the pike (localities 21 and 22). Underneath 
the Dayton limestone is found the deep red sandy Clinton, and 
below this the ferruginous and at times odlitic Clinton, but no 
pebbles were seen. About a mile south of Ellenville after cross- 
ing a somewhat larger culvert, and where the pike ascends a 
somewhat steep hill, the Dayton limestone is exposed in the 
woods (locality 23) at some distance east of the pike and at a 
fair elevation. Tracing it eastward, it seems to rise in altitude. 
Along the pike (locality 24) the Clinton is well exposed. It is 
often well cross-bedded and in different directions. Ascending 
the hill, quite a thickness is well shown. Reaching the top of the 
hill, a little streamlet, descending rapidly to the middle fork of 
Brush creek, again well displays the Middle and Upper Clinton 
(locality 25). It is deeply red in color, of a sandy type, and 
frequently cross-bedded, but does not show, where examined, any 
pebbles. At the creek, a short distance below the point of entrance 
of the little streamlet just mentioned, the base of the Clinton is well 
exposed (locality 26). About eight feet of the Clinton are seen, 
containing cherty concretions in nodules and along vertical cracks, 
and showing the so-called shelly layers mentioned in connection 
with the Smart section near Belfast, and also some very siliceous but 
not exactly cherty layers. Meristella umbonata was found here.
