STRATA OF HORDWELL CLIFF. 167 



westward of a ravine that is situated half a mile 

 from the village of Milford. It is about ten or 

 twelve feet above high- water mark, and extends 

 many yards along the cliff.'* The freshwater beds 

 continue as far as Beacon Bunny, and in the upper 

 part of that ravine, beneath the alluvial gravel, 

 there is a bed of fluvio-marine sand, containing an 

 intermixture of estuary and fluviatile shells, which 

 may be traced to the eastward under the fresh- 

 water marl, to about 300 yards from Mead-end, 

 where it disappears beneath the shingle of the 

 beach.f This is succeeded by fine white siliceous 

 sand, like that at the base of Headon Hill, form- 

 ing a stratum from 60 to 100 feet thick. The 

 London clay series next appears, and extends 

 through Barton and High Cliffs. The upper por- 

 tion of the beds consists of sandy clay of a dark 

 green colour, like that at the base of the cliff in 

 Alum Bay (marked b in lign. 11), and abounds in 

 marine shells ; beneath are layers of septaria. 



The strata at Hordwell Cliff are regarded by 

 Mr. Lyell as the equivalents of the lacustrine beds 

 which form the coast from Yarmouth to Gurnet 

 Point, where the strata lose the character of an 

 indurated calcareous marl, and are not unfre-
