CHAPTER XIII. 



THE RIVER VALLEYS OF SOUTH-WEST IRELAND : THE 

 VALLEY OF THE WEALD, AND THE FIORD OF 



KILLARY HARBOUR continued. 



FROM the description in the last chapter of Killary 

 Harbour, and the different kinds of estuary deposits, 

 it is evident there are no proofs that the flats in the 

 County Cork below the 350 feet contour-line were 

 formed by the rivers flowing in them, while it 

 appears highly probable they may be old estuary 

 bottoms, as the gravels associated with them are at 

 certain elevations in all the different valleys, as if 

 due to one universal agent, such as the sea. In some 

 of these flats the work of rivers is apparent; these 

 having cut passages here and there, and afterwards 

 filled up the channels, or perhaps left them as irre- 

 gular trenches after they had taken new courses. 



From S.W. Cork we now proceed to the valley 

 of the Weald, which has been put forward as one 

 of the great proofs of enormous subeerial denuda- 

 tion. We will specially refer to Messrs Foster and
