Graham, Young Co., Texas. Monday March 20-1922. Another cool but bright spring day. Before starting called on Mr. B. Cheney, the local oil geologist. He says he has cammities and will get them in one. Says they are not rare, but are rather limited to thin zones. Then with Bean went 8 miles S.-E. of Graham on North Mineral Wells Road. Collected here in the overlying Jacksonboro limestone, which Cheney says is 130' above the Canyon Series. The species are different here but did not get as large a lot as hoped for. Fragments of the cordiforms (Plate- cores group seen indicating these z. putamen. In the afternoon collected about 1 1/2 miles N.-W of Graham. One small area that has often been picked over. The horizon is the Weland shale.
