Mr. Buckingham also contributes a photograph of the cliffs of 

 St. Margaret's Bay before the great rock-fall of January 1905, and 

 several others taken after that fall. 



At my request Mr. Hodson, of Loughborough, kindly took a large 

 series of beautiful photographs of the Blackbrook Valley in Charnwood 

 Forest. This valley is of exceptional interest, because it is the unique 

 example in the Forest of a Triassic valley out of which the Triassic material 

 has been almost completely scooped. It therefore differs in landscape 

 character from any other valley in the Forest, and indeed in the eastern 

 part of England ; but its special features have now been lost, as it is 

 submerged under the reservoir of the Loughborough waterworks con- 

 structed by Mr. Hodson. Unhappily Mr. Hodson died shortly afterhe 

 had completed this work, and his many contributions to the collection 

 will be much treasured. . 



A serious loss to the Committee is caused by the death of one of its 

 most active members, Mr. W. Jerome Harrison, who may be styled the 

 pioneer of geological photography and also of systematic photographic 

 survey work. The collection contains some hundreds of specimens of his 

 work, and the Committee still hold a considerable series of photographs 

 in Suffolk, which only need indexing to be incorporated in the collection. 

 It was at the York meeting of the Association that Mr. Harrison 

 brought before the Conference of Delegates an important paper on ' The 

 Desirability of Promoting County Photographic Surveys,' one outcome of 

 which has been the attempt to collect and exhibit a set of scientific 

 photographs each year illustrating the district in which the Association 

 meets. An admirable example of such a collection was exhibited at 

 Ppblin during the current meeting,
