Discussion. 



Dr. H. E. Mill said that he was much interested in the Author's 

 observations, especially those on Hayeswater. He wished that there 

 were facilities in the meeting-room for optically projecting photo- 

 graphs, as a photograph he had taken from the top of High Street 

 showed the glacial accumulations in the narrow valley very 

 distinctly. As Mr. Marr had found every tarn that he examined 

 to be held in by a barrier of drift, it seemed very likely that most, 

 if not all, of the larger lakes would be found to owe their origin to 

 the same cause. In this connexion it was worth mentioning that 

 Prof. W. M. Davis, of Harvard, considered, from the configuration 

 of the larger lake-basins in the district, that they were produced in 

 drift-blocked valleys. 



The Atjthoe thanked Dr. Mill for his remarks. He observed 

 that even if Hayeswater were abnormally deep for mountain-tarns, 

 there was sufficient drift to block it. He had already written 

 a paper on the origin of the larger lakes of Lakeland, and submitted 

 it to another Society.
