Graham, Texas.
Tuesday March 21- 1922.
A bright morning.
Started out alone on foot for the places
in the Dayland shale to the south east
of Graham about 1/2 miles. Found no fossils
at either of the four places in this vicinity.
Then looked up the A. B. Sant locality
on the west side of Salt Creek at the dam
of the Graham crater works. The fossiliferous
Dayland shale is here high up the hill
side and so little is exposed as to yield
almost no fossils. This is probably due to
taking out the rock when building the dam.
At least no one will make a good collection
here. It is nowhere equal to the one collec-
ted from yesterday.
At the dam the Sunlight limestone is a
very muddy limestone - one hardly can call it
a limestone - is about one foot thick and just
above it in the shale occur the fossils.
Above the shale is a very thin sandstone
