The British Vegetation Committee. 
who circulated an excellent programme several months before, so 
that members were able to make the arrangements necessary for 
attendance. There was also a day’s excursion over the Wicklow 
mountains during the Dublin meeting. At Cambridge the Committee 
business was followed by two days in the open, one in the “ Oxlip ” 
woods on the chalky boulder clay, and the adjoining dry oak woods 
on the Lower Greensand, near Gamlingay, to the west of Cambridge, 
the other on the heaths near Mildenhall in West Suffolk. Here 
again the local arrangements were carefully made some time 
beforehand. The advantages of such excursions, where leaders 
familiar with the vegetation take the stranger to the district over 
typical plant-formations, are obvious. 
In July, 1908, one of the members of the Committee joined 
Professor Schroter’s excursion through the Swiss Alps, and a 
proposal was then made to arrange an international excursion in 
the British Isles. The idea was heartily welcomed by Professor 
Schroter, of Zurich, Professor Flahault, of Montpellier, Dr. 
Ostenfeld, of Copenhagen, and other continental plant-geographers. 
It is hoped to arrange this excursion in August, 1911, and the 
Committee would like, if possible, to extend at least a partial 
hospitality to visitors, if funds can be secured for the purpose. 
Committee Business. 
The business at the meetings has mainly centred in one or 
two matters relating to standardisation of observations, and the 
effect of resolutions adopted may be briefly summarised. 
Publication of Maps. The need for uniformity in scale and 
colouring of the published maps relating to “ primary surveys ” 
of vegetation has been felt by the Committee since its formation, 
but the publication of memoirs by different Societies has made 
such uniformity difficult to secure. An important experiment in 
publication is now being made. A map of the Peak District of 
Derbyshire, comprising two one-inch-to-the-mile sheets (new series), 
with a memoir by Dr. C. E. Moss (Cambridge) is now being 
prepared for publication, the map being printed at the Ordnance 
Survey Office. It is hoped that this may become a permanent 
means of publication, and so remove the hindrances to publication 
of primary surveys which have hampered the Committee’s work 
during the last few years. In order to maintain a uniform standard 
in the memoirs published in this way, the Committee will appoint 
annually a “ Primary Survey Publication Sub-Committee,” whose
