The following is a list of the plant remains collected from the fos-
siliferous portion of the above section: -

Araucaria bladenensis Berry. Cunninghamites elegans (Corda) Endl.
Chondrophyllum Nordenskioldi Heer. Malapoenna horrellensis Berry.

In the southern part of Johnston County, at Bentonville, and on
the side of the valley of Stone Creek where it is crossed by the Smith-
field and Wilmington wagon road, there have been observed a few poor
exposures of white to yellow sand with lenses and laminw of drab,
purple, and chocolate clay, which are believed to form a weathered
phase of the Black Creek formation. eee

Exposures of the Black Creek formation occur in the bluffs of Neuse
River from Blackmans Bluff, 11714 miles above New Bern, in Wayne
County, to Whiteley Creek Landing, 60 miles above New Bern. From
the first-named point to the A. C. L. Railroad bridge southwest of
Goldsboro the formation rests unconformably upon the undulating
surface of the Patuxent formation, which at the latter point passes
finally below water level. It is overlain unconformably by Pleistocene

_ terrace deposits and by several basin-like occurrences of Eocene strata.
‘Below Whiteley Oreek Landing the beds are believed to pass conform-
ably beneath the overlying Peedee formation. (See sketch map of
Neuse River, Fig. 4, p. 96.)

In descending the river from Smithfield the first high land observed
approaching close to the river banks was at Blackmans Bluff. Here
the Black Oreek formation was first seen. The lower 20 feet of the
section was exposed at the time, the water being 4 or 5 feet above

normal.
