The lower part of this series east of the creek shows fish remains. The coral clambrecid Crus galli occurs in this bed. At various levels corals occur in the rock. They are more common near the top. At the top of the well stratified series profound concretary masses of chert with spirifer with radiating plications & eteise, Derwilum and corals such as Cystiphyllum Dervinia form it. Total thickness measured 17 feet with the chert in the upper 2 feet. Massive strata, weathering dark brown externally, interior it has the appearance of irregularly angular fragments embedded in a cement. The stone does present sharply defined stratification plane, or rather no stratification at all could be observed so that it had a very volcanic appearance, but it enclosed the same corals as those found in the bedded rocks immediately below. Thickness 8 1/2 feet. Continuing this aspect of the Devonian rock, the total thickness of the Deruvian here is about 6 + 1 + 9 + 17 + 8 1/2 = 42 feet Overlying the Deruvian is the Black shale, the source of the alum spring water. In the black shale about 15 feet above its base occur thin calcareous layers with Discret Singula. The "volcanic looking" phase of the Deruvian does not make its appearance along the creek and the exposures are confined to the south west corner of the field. I started by being alert to make of it but it is probably only a very massive bed.
