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
