general testimony of old inhabitants, the channel of the river has 

 become both wider and deeper during the last twenty or thirty

 of a lake, and thus accounting for the tradition.

 hiatus between the Pentamerus Knightii-limestone and the overlying, 

 so-called Devonian. 



The Eev. H. H. Winwoob and Mr. J. E. Mare also spoke.
