of Shingle in all Britain is on the west side of the River Aide in Suffolk reaching north-east to Aldeburgh, and it is still increasing at lts south-west end. It is one of exceptional interest, since it shows m great perfection a peculiarity which is not common to Shingle-beaches : the arrangement of shingle in long sweeoing and parrallel ridges or ' fulls,' as though furrowed by some gigantic plougb. This formation may be studied with profit at also Dungeness, Orfordness and Felixstow. But the beaches of our east coast stand in strong contrast to those of the south in their composition : that of Felixstow is of the local pebbles of Flint denved, not directly from the chalk in which it was formed but, from Red Crag capping the Clav cliffs and from surfacewashings, and Gravels of later age than the Crag which have come from the north. After flints, in number, come pebbles of milkv Quart? which also have come from the north, possibiy Norway. If those lying basking on the beach trouble to turn over handfuls of pebbles, they will find a most surprising wealth for, besides pebbles of Chalcedony or Agate and beautiful C.arnelians whicb have drifted, like the Agate, down the coast from east Scotland there will be others of black or green red-veined Jasper, pebbles ol fine wine-red or purple stone often veined with quar.z whicb have travelled apparently from Scandinavia. Mixed with them are great numbers of chocolate-coloured pebbles that have a remarkable historv : briefly, thev are known as 'Cement Stones ' that used to be dredged from the sea-bottom and ground into cement ai Harwicb ; they were formed ages aeo when the sea was here throwing up the' old shell-banks of the Ked and Coralline Crags on to a floor of London-clay, which was at that time strewn with enormous quantities of Whale-bones specifically now extinct. All over this part of Suffolk the Craä is underlam by these nodules of clay, hardened by phosphate of lime, together with innumeranle bones and teeth, forming what is known as the Suffolk Bone-bed or Nodule-bed; and hundreds of tons of them have been manufactured into manure known as ' superphosphate.' Locally these nodules are termed Loprolites under the mistaken notion that such bits of Clay were
