In no part of England is there more striking evidence of this movement than in the coast district of Norfolk and Suffolk. The old land surface which went down and was re-elevated nearly to its former level, is well known in these parts as the Forest Bed, which now forms the bottom of the sea at a short distance from the shore from Cromer to Kessingland. It appears as the lowest stratum of the cliff at Kessingland, and at other places on our coast. It is also disclosed in inland pits from which some of its most marvellous relics have been extracted. That the surface of this bed was once above water and covered with terrestrial vegetation, like that on which we now have our being, is proved by the stumps of trees which have been found fixed upright in it, as they were when alive and growing. A specimen of these old tree stumps is to be seen in the Norwich Museum. It is on this old land surface and more or less embedded in it, that the relics of an older world are buried, which so frequently make their appearance in the trawl nets of our fishermen,—the teeth and bones of Elephants, the Rhinoceros, Hippopotamus, and other animals, which now belong to the fauna of countries far away to the south. This old land surface has been covered with some hundred or more feet of sand, clay, and gravel deposited upon it during the process of subsidence, and which after the re-elevation of the Island formed the surface soil of a great part of Suffolk and Norfolk. The process of subsidence and re-elevation was probably extremely slow, producing an alteration of about two feet in a hundred years. An elevatory movement of this kind has been known to have taken place in recent times in the northern regions, and is said to be still going on in Finland. How many thousands of years ago this movement took place is a matter for geologists to discuss, the important point that we have to bear in mind is that from the time this movement ceased all the alterations which have taken place are due to causes still in operation and acting in the same manner now as then. What was done by the sea in carving out the surface into hill and valley during the process of elevation we know not, but Mr. Edwards is probably right in holding that when the upward movement ceased the contour of the surface, as regards highlands and lowlands, hills and valleys, was very much what it is now. In considering the effect of the natural forces still in operation during the many thousands of years during which they have been at work, it is necessary to bear in mind that the level of the sea has all along remained the same, except so far as it is varied by the rise and fall of the tide, and by the exceptional exaggerations of tidal movement caused by the wind.
