If the Pennsylvanian should be drawn at the base
of these sandy- argillaceous li and shales both here
and in the Catskills. * See below, and Monte page
I did not see a trace of a Hastroid here today
nor has anyone ever found me. They certainly are not from
the Drapanocella limestone paper, and those gotten by
Drillis must come from either the shale below or the
argillaceous li. beneath.
Beneath the argillaceous li. comes in the dark-
Hue shales of the Carey. What their relations are here
with the Judd fault cannot be determined because of
the Chretone Fault. There is a part thickness of
Carey here to judge by the valley on the 7th side of
Limestone Ridge. Here is at least 100 feet of Carey.
Over the Drapanocella Limestone is the Clinton
Shale reported to have a thickness of 3000 feet. It has
ferruginous sandstones.
Ballis' various Drapanocella series sections show
that the sedimentation is very variable. This is in har-
mony with the fact of the beginning of a new period and
one of very rapid deposition.
* In the Benayan horizon I got large Pateclostium, Northen-
ia, one cut end, and saw two others that I thought were
Camptophyllum Torquium (small about 3 times in diameter).
