Many small fossils areather only the lower beds and lie in lown ground. I had no time to collect it. Keyte has a lot of it and if necessary get him to loan one a collecting. The fossils show clearly that these Lower Sap- tank strata are of the regular Pennsylvanian and out of the earlier time within, and certainly not at all of the Bend-Morrow-Drabannocka Time. As I see our Charites most likely but rather the Cretomemi lians. I am wondering if the time may be early Canyon. It is certain as late Wolfcamp Shawn. The folding of these Tresnus-Hinfe-Hagmond strata their age may falls in Bridle Pennsylvanian Time. In later work, What the relation is to the Upper Sapbank, Blan- hard says cannot be determined at this place since there is none here on any of the Per- Mian series. They are angularly related to the Comanchian basal sands and than the loney series, but the exact age I do not know (Prof Edmons) Then entered south west to Wolfcamps where This is my locality collected from two feet after these ammonites, or all collected and minute. do not occur in the Wilfcamp but in the Upper Sapbank, in blue shales. Left but few fossils although Keyte said he had at least 10 specimens of ammonites. It hailed and rained at 4P.M. and we are concluded to go back to Alpine. On road from Marathon to Saptank one turns to the same locality m at 11.6 miles out of Marathon; have a mild mill to S.
