At Sykes Landing, 74 miles above Wilmington, left bank, a section
similar to the preceding is exposed, from which the following fossil
plants were collected:

Araucaria bladenensis Berry.
Chondrophyllum Nordenskioldi Heer. 2

Cunninghamites elegans (Corda) Endl.
Cephalotaxospermum carolineanum Berry.

Near the site of an old mill one-fourth mile northeast of Sykes Land-
ing, on land owned by ©. S. Bradshaw, a few shell prints were obtained
from fragments of sandstone which according to the owner were dug
from a rock layer closely underlying the surface in the immediate
vicinity of the mill. This rock is probably a lens in the Black Creek
formation. The forms include Glycymeris (?), Cardiwm sp., Tellini-
mera (?), ete. (U.S. G.S. Loc. No. 5355.)

The next interesting exposure observed was at Big Bend, where the
following strata appear: '
