168 Botanical Photographs. 
Broads, and continued across the end of the (largely grown-up) 
Broad itself, soundings, and samples of the bottom-vegetation being 
taken every few feet. Facilities were most kindly given by the local 
landowner for carrying out this survey. Other sections were taken 
from high tide-mark across the dunes, shewing the gradual change 
in the flora from “ white ” to “grey” dunes. 
The surveying was done on tracings taken from the 0500 
Ordnance Survey Maps. This large scale was found necessary to 
shew the local variations of the vegetation. 
Though considerably less was actually accomplished than had 
been planned, the expedition may be said to have been very 
successful. Some interesting data were obtained, and there is no 
doubt that the main object, to bring the members of the party into 
intimate contact with these extensive and practically untouched 
“ plant-communities ” was fully realised. It is intended to continue 
the work in the future, as opportunity offers. 
BOTANICAL PHOTOGRAPHS. 
Mr. Alfred W. Dennis, of 45, Park Street, Stoke 
Newington, has a collection of photographs of British Plants in the 
form of lantern slides, to which he is adding as opportunity offers. 
Most of them are very successful portraits. In the case of trees a 
flowering and fruiting shoot has usually been photographed, while 
the small plants are taken in their entirety. The price is one 
shilling each.
