Marathon, Texas, March 21-1924, Friday With the old dilapidated Ford and the boy Lauffen went about 18 miles northwest to the junction of the Brad Canyon into the Lillian canyon. Here on the southeast side of a four mile ridge occurs some 25' or a thick reddish limestone about 64' but thick of the Permian (Basil formation) of Uddins Section #1-4. Here occur large Permian Fusulinids, some of which must be an inch long and nearly one-quarter inch thick. Also some large Lob- tidus but no Rickettsiaenia. One layer of pelitic limestone in relation with Ammonites. One can carve one's initials into the rock with the hammer, but as they weather out the oilicity, and as not good pencil marks they are to be seen by the thousands. Looked about 5 hours to get them, and I think have a representative lot. One sees almost no other fossils.
