THE BRITISH VEGETATION COMMITTEE’S EXCURSION 
TO THE WEST OF IRELAND. 
rpHE excursion of the Central Committee for the Survey and 
Study of British Vegetation, organised and conducted by Mr. 
R. Lloyd Praeger, and lasting from August 27th to September 1st, 
was by far the largest and longest yet attempted. It was attended 
by seven members, F. J. Lewis, C. E. Moss, R. Lloyd Praeger, 
A. G. Tansley, F. E. Weiss, T. W. Woodhead and R. H. Yapp, and 
by four visitors, Mr. Adamson, Professor F. O. Bower, Mr. F. T. 
Brooks and Professor W. E. Praeger (Kalamazoo, Michigan). The 
members were greatly indebted to their leader, whose admirable 
arrangements and knowledge of the country and its botany enabled 
the party to spend the available time to the best advantage. 
The two areas investigated were the low-lying bogs and some 
of the hills of Connemara (County Galway), and the carboniferous 
limestone region on the borders of Galway and Clare. 
Connemara. 
Connemara is a country of barren hills of metamorphic rock 
enclosing great stretches of nearly flat bogland, not many feet above 
sea level, interspersed with innumerable lakelets. The party spent 
a long day in the southern part of the most extensive area of this
