Survey and Study of British Vegetation. 25 
scheme of colours for representing the British plant-associations 
should be deferred for the present, pending further experience and 
consultation. 
Photographs. A collection of photographic prints of vegetation 
should be made, each print to illustrate a definite association or 
feature of an association, or a definite plant form characteristic of 
an association. The quality of the negative from which prints are 
accepted should reach a high standard. There should be no limit of 
size up to whole plate. Prints should be sent in unmounted and 
accompanied by a detailed explanation. The collection will be 
mounted on cards, properly arranged and indexed, will be kept in a 
definite place to be decided on later and will be available for 
reference. 
At the next meeting of the Committee, which will probably be 
held in March, 1905, the provisional resolutions and constitution of 
the Committee will come up for confirmation. It is also proposed 
to consider at that meeting a scheme of terminology of the units of 
vegetation, which can be communicated to the International 
Botanical Congress to be held at Vienna in June, 1905. 
It may be of interest to make a short statement of the progress 
which has actually been made up to the present time with the work 
of survey and mapping.
