VII.—The Shell-beds of Moel Tryfaen

Abstract

The idea that the well-known shell-bearing sands of Moel Tryfaen indicate a submergence to the depth at which they are found, cannot perhaps be yet said to be, in the language of Mr. Dugald Bell, “a day-dream of the past,” though it is fast becoming so. Towards this result there must be two stages—disbelief in the submergence, and belief in something else. As to the first, Sir A. Ramsay wrote—“He must be a bold man who could see the shellbeds at Moel Tryfaen and deny that the sea had been there.”
