RAISED BEACHES, CLIFF AND RUBBLE HEADS. 235 



I am seriously inclined to associate these clay deposits 

 with the clay of the " heads." They are alike in colour and 

 consistency, and occur in the same order, for I have traced 

 the margin of the Forest bed (13 feet thick), on the north- 

 west edge to its connection with the overlying uppermost 

 layer of the " head." The clays in some places show a distinct 

 stratification. You will see that my views have recently 

 enlarged and that I am now obliged to admit that the evi- 

 dence of submergence for the whole island has gained such 

 strength as to oblige me to believe in such submergence. I 

 shall, in a few words, place my conclusions and the evidence 

 for such submergence before you. 



CONCLUSIONS. 



That the beaches and heads prove that the island has 

 been completely submerged during the " recent " period. 



Evidences : — The beaches and their remains at all levels. 

 The association of the clays with the remains 



of the beaches. 

 The evidence of stratification in the clays. 

 The presence of the clays at the highest 

 levels. 

 For the purpose of to-night's paper I confine myself to 

 this conclusion. I am perfectly willing to admit that there 

 exists ,a strong amount of contrary evidence, in fact, it was 

 the presence of that contra-evidence which prevented my 

 coming to my present conclusion long ago. I thought the 

 apparent want of stratification in the lower portions of the 

 head unanswerable, but I have given the matter careful 

 examination in the field during the last year, and I now am 

 forced to the conclusions I have placed before you.
