D. This should be the Waldron
Shale... The lower 1 3/4 ft, consist of
shaly limestone with fossils. A-
nery thin the large Pynch mella
Stricklandi.
Above this lie 6 ft. of Clay with num-
erous specimens of the flat limons.
This layer is an one fossiliferous
east of Pegram 1/2 miles. See parts
next page,
E. This is a very fine building rock
and should be equivalent to the
Simisville limestone, stratigraphi-
cally.
Phosphate rock abound in Lingulae,
Mr Finbee + Blee's Hollow the following
section, found. Brown phosphatic
rock 3 in, at base/ 6 in of fissile
Black Shale / 9 inches of dark phos-
phate rock with Lingulae. Plenty
of Black Shale with earthy layers
intercalated at various levels,
A cherty bed about 1 foot thick
occurs about 10 feet from base of
Waverly.
The Black Shale presently goes un-
der cover a short distance W.
of the bridge, it dips strongly
S.W. as to get to the water's
edge, a quarter of mile south of the
bridge. Coming to the same place
the lower limignus are quickly brought
up in spring E,

About 1/2 miles E of Pegram Sta.
on N. side of RR is bridge of S arm
Walker, A short distance West of same
a road leads SW through the woods
to Harpeth river. Another road
runs along the north bank of this
river, and following this road
Eastward, the following section
is found at the end of the cliffs,
near the point where the road
leaves both the cliffs and the river.
Black Shale
14 miles phospatic rock
28 ft. limestone = Simsville L. C.
12 1/2 ft of clay + claysl, Waldron B
Fossils
4th p.foll.
21 1/2 ft. Laurel limestone, A
51 feet down to river's edge
not exposed. See
next section.
A. Pizginnus gemmiformis occurs
below the Waldron shale bed.
B. The lower part of the Waldron
shale is more like a clayey limons
+ is very fossiliferous. The upper
part is pure Clays, The very top
is not exposed. Exposed at:
C. The Simsville limestone is 20 ft
thicker here than 2 1/2 miles west-
ward at the bridge W of Pegram.
