Every place seen today in the so-called Lower [illegible] turns out to be Lower Baptau, with decided suggestions of the Upper Baptau. It is still several miles W. to the peak ore of the Pennian and plenty of room for the whole of the Baptau, but as well in the Tennes-Dimple if it is another series which I may much doubt. All the forms reported by Baker in Heddens' Report of the Glen Out are Lower Baptau species, as there is no break between Lower and Upper Baptaw and as both are equally folded it follows that the Time of Out-molding is after Baptau time. To obtain we will collect Griefcamp traps and study the relations of the Baptaw to the Griefcamp. The great break between the Pennsylvanian and the Permian comes in above the Upper Baptau, but what is Griefcamp?
