SUBMERGED FORESTS, AND RAISED SEA-BEACHES. 



Sir, — In the Quarterly Journal of the Geological Society for 

 February, page 4, Mr. Wynne says that peat and timber trees 

 are found beneath the Youghal Strand. In accounting for this 

 he goes into the old error of the necessity of a '' subsidence of the 

 land." Mr. Wynne says : " At some time (about the close of the 



Glacial period perhaps) the land became depressed — it 



may be generally — as such evidences are common round the shores of 

 Ireland as well as parts of England, but whether generally or 

 locally, the land here sank to a depth of more than 90, perhaps 100 

 feet, or even more. Subsequently, to this depression of 90 or 100 

 feet the land rose again." Mr. Wynne further says that, " On the 

 landward side of the beach the low ground is covered with peat 



The water from the low boggy ground is conveyed through 



the beach by the usual contrivance of tidal floodgates or sluices, so 

 that there is reason to believe that the peat on land and that beneath 

 the bay are at the same level, and connected under the beach ; and 

 that the sea, by throwing the beach up, has banked itself out from a 

 considerable portion of the low ground." 



This is the precise description which I have given in Rain and 

 Rivers of our English so-called " submerged forests." They are all 

 choked up estuaries, and Mr. Wynne and every one else must see
