DESCRIPTION OF THE PLATES. 25 



section, 200 feet high, of the Upper Chalk, with 

 numerous layers of flint, the strata being highly in- 

 clined. At the base of the projecting cliff is the entrance 

 to a large cavern, formed by the continued action of the 

 surge on the chalk rock. 



PL XI.- — View of the Cliffs from beyond Compton 

 Chine to Brook Point, as seen from near the 

 base of afton down. 



The foreground is part of the southern slope of Afton 

 Down, and consists of the flinty chalk. The pathway 

 winds over the brow, and leads to Compton Chine, down 

 which a rude foot-track conducts to the beach. The 

 strata at this point are the cretaceous ferruginous 

 sands, which emerge from beneath the Gait on the west, 

 and are succeeded on the east by the Wealden deposits ; 

 but the face of the cliffs along the westernmost part of 

 Compton Bay is not seen in this sketch. The strata 

 forming the cliffs, shown in this view, are the sands, 

 clays, and shelly limestones of the Wealden. 



The first point of land jutting into the sea, and ter- 

 minating in ledges or reefs, is the western boundary of 

 Brook Bay ; at the base of the cliff* is the fossil forest 

 of the Wealden. The limits of Brook Bay are shown 

 by the head-land beyond, which is the eastern point. 

 The farthest land on the shore is the cliff near Black- 

 gang Chine. Saint Catherine's Hill rises in the remote 

 distance.
