bounded by cliffs, and on the farther side was the fishing 

 village of Clifftown, nestling at the foot of a deep ravine 

 up which ran the road along which our return journey 

 must be taken. 



Following the line of cliffs, we found that the basalt 

 came to an end about 100 yards beyond the point, and 

 was replaced by the chalk, which was again saccharoid 

 near the junction. 



Many caves had been drilled in the base of the 

 chalk cliffs, and most of these lay on lines of jointing, as 

 the cracks which traverse the rock at right angles to the 

 bedding planes are called. 



In one or two instances the waves had drilled 

 tunnels through a small headland, thus forming a natural 

 arch, and in others the crown of such an arch had fallen, 

 leaving its outer buttress standing as a detached 

 pinnacle of rock now surrounded by the rising tide. 

 Stacks of this description were to be seen at intervals 

 all along this part of the coast, and they bore witness to 

 the enormous destruction of the coast-line by the action 

 of the waves (Plate III.). 



As we penetrated farther into the bay we found that 

 there was no longer a raised-beach platform such as 

 that on Black Point, but that the shingle beach lay 

 against the foot of the cliff, only the storm beach being 

 now above the water as it was high tide. Travelling 

 over the shingle was somewhat arduous, and we therefore 

 waited for the ebb of the tide, the interval being pro- 

 fitably occupied by an examination of the cliff face. 



Near its base the cliff showed many signs of the 

 battering which it had suffered from the shingle being 

 flung against it during storms. The shingle here con-
