The sea again come in and laid down a land buried when channels were worn through ② into ③. The sea again come in and laid down the Birmingham clays without marine life but at all places this is healed at the top. It filled in the hollows quicker and eventually are was a flat limestone bed running of again but river from micaceous sandstone. At one time Ragnmund thought he had 20 or more coal sequences but became alarmed and gave up.
