mily. Then crossed over to the
north in a small quarry and
there found the Springfield Cliff,
a dark blue sandy limestone, it
in layers of mainly 8 in layers and
one 2 ft layer. I could see no
fossils in these beds at all.
These are overlain by 10 ft of
sand rock holding some chert,
all fossils are rolled and
crystallized. For [illegible]
calcite. Mr. Lacy calls
it the jopple bed.
Above this should be the
Pentamerus bed but nowhere
could I see it exposed. They
cut in the ocean a qualt upon
it and in opening the street
they open the layers holding
Pentamurus oblong us.
