Wednesday, November 5 New York. Called on Professor Berkeley and Mr. Hoeren at Columbia University. Berkeley says that the Cretaceous monoculites of Oklahoma are one of the best examples of metamorphism upon a volcanic ash beds. The ash appears to be metamorphosed from tuffs to this the alteration is too gradual to make certain. Mr. Hoeren showed me his very large scale map mapping One Comanche county. In the southeast corner occur the older rocks for Cambrian of the monoculites. The folds run east and west and the thrusting appears to be to the north. Further away the folds trend N.E.- S.W. To the north and northwest him finds the Starly and then the Jaedford. The Bradford like cherts lie about in the center of the Starly and trend N.E. and S.W. Hoeren says that these were folded at one time and in middle Pennsylvanian Time. As he has no Pennsylvanian strata in his area this statement is based on general knowledge. The Jaedford is folded as it is the youngest formation in his area. The Comanche outcrops in the south. Hoeren wants me to use Shannon to call
