loess in the typical regions was its wide extension in homogeneous 

 sheets ; and it seemed hardly advisable to apply the term specifically 

 to a small isolated patch, such as that described. The Author's 

 attempt at a general classification of the Drifts on the basis of the 

 Durham sections deserved consideration, but was necessarily of 

 limited value, like the many previous attempts of this kind. The 

 speaker's experience had been that the sharp boundaries observable 

 .among the East- Coast Drifts in several localities, though often 

 traceable for some distance, always faded out sooner or later, and 

 were not confined to any particular horizon.
