studying and mapping the vegetation 
of Delamere Forest, Cheshire ; and 
Professor R. H. Yapp is continuing^ 
his experimental studies on the eco- 
logy of Wicken Fen, Cambridgeshire. 
Pictorial records or photographs 
of natural monuments are much to be 
desired, and the British Association 
Geological Photographs' Committee, 
the British Association Botanical 
Photographs' Committee are already 
at work on these lines. Besides this, 
the Central Committee for the Survey 
and Study of British Vegetation collects 
photographic prints showing features 
of ecological interest and illustrating 
definite members of plant associations. 
These collections, at present, are lodged 
at University College, London, and 
duplicate collections are deposited at
