Not illustrated. 1882 Excerpt: ... in one direction, for the coast curves, and we can trace the horizon, both southward and westward. Further evidence of the regularity of the rise and fall of the land, is the way in which the different deposits thin out as they are traced westward. In that direction the Chalk rises, and the marine appear to overlap the fresh-water beds against the rising land. The lower portion of the " Forest-bed," which contains most of the large mammals and a very littoral marine fauna, is also overlapped; and the Rev. 0. Fisher is probably correct in stating that it only extends a short distance west of Lower Sherringham. This view accounts without difficulty for the absence of the fresh-water and estuarine beds in the neighbourhood of Norwich, for that district was probably above water and covered by fir forests during the formation of the Cromer "Forest-bed." The most important feature in the physical geography of the period was undoubtedly the large "Forest-bed" river; and if the direction of the flow of this river can be traced, we have the key by which the general structure of the country can be made out. With a view to decide this question, the old river gravels haye been carefully examined, for they must have been derived from the land over which the river flowed. These gravels commonly contain fully 40 per cent, of stones other than flint; and after a study ot the Glacial gravels and Boulder Clay stones, it is at once clear that they must have come from quite different districts. The proportions of the different rocks in 500 stones over an inch in diameterj obtained at Bacton was: --Little-worn flints----141 Pebbles of light-coloured fine-grained quartzite 125 " fliut----101 " vein quartz--54 Quart.
