We then ventured about 7 miles further S.E.
across Upper Cretaceous farm lands when there
was a little rise in the country, making the basal
Chidway - Erone. There was a perceptible dip over
and on these sandy beds that had an abundance
of large flint concretions. Another mile S.E. brought
us to the gate of J. O. Caldwell's farm, and then
it was 2 or 3 miles to the N.N.W. to the fossiliferous Bridgway.
What one saw here was less than
10 feet of Bridgway are highly fossiliferous. Below
in 5-6 feet to river level was Greenish - Haed clay soft
caly reflect with Venericardia in small nests
and large aggregations (those about one foot thick) that
occasionally made a hardened layer (took one large lump).
Most of the shells are double valved and far more

and probably held in place by a tireous. With these

feet, and one collecting was out of the central gneiss.
Here seem many kinds of gastropods and smaller
bivalves along with several species of cup brachials.
The clay was so wet and soft that I do not if
