Survey and Study of British Vegetation. 
Areas under Survey. Messrs. Lloyd Praeger and Pethybridge, 
Co. Dublin (Ireland); Mr. Hardy (Scotland), west of Forfar, Fife 
and Perthshire, and northwards; Mr. Rankin, Lancashire west 
of the Pennines, and Hampshire ; Mr. Lewis, extension of West¬ 
moreland area, westwards and northwards ; Mr. Moss, Cheshire 
and Derbyshire; Dr. W. G. Smith, Yorkshire Clevelands, Wensley- 
dale and Swaledale ; in addition some work is being done in North 
and South Wales, and in Aberdeenshire. It will be seen that con¬ 
siderable progress has been and is being made in this effort to 
obtain a systematic acquaintance with British vegetation, and to 
reduce it to a form in which comparisons can be made between 
regions widely apart. Gaps are still numerous, however, even in 
the mountain and moorland country, while considerable areas of 
of ecological interest are untouched, and will probably remain so 
unless undertaken by fresh workers. 
Ecological Study of Vegetation. The above mentioned surveys 
of wide areas carried out on a comparatively small scale and affor¬ 
ding only a primary analysis of the vegetation, ought to be supple¬ 
mented by work of a more detailed character. This is also being 
undertaken. Mr. T. W. Woodhead recently communicated some 
of his results to the Linnean Society (December 15th, 1904). Mr. 
Woodhead has devoted himself principally to the survey and study 
of woodland areas in South-West Yorkshire. The mapping is done 
on the ordnance survey maps of six inches and twenty-five inches 
to the mile, and all kinds of data bearing on the vegetation has been 
collected. The biological laboratory at the Technical College, 
H uddersfield, is available and suitably equipped for ecological research 
and is within easy reach of the woodlands. In the woods themselves 
convenient huts have been placed at the disposal of workers for the 
purpose of research, and every facility has been granted by the owners 
and by a neighbouring resident to those desirous of making experi¬ 
ments and observations on the spot. Mr. Woodhead is thus doing 
pioneer work in this department so far as this country is concerned. 
Mr. Tansley has also begun mapping work on a similar scale in 
Kent. The Committee is desirous of promotiug this more 
detailed survey and study side by side with the mapping of large 
and more uniform areas, and will be glad to give further 
information. 
Communications may be addressed to the Secretary of the 
Committee, Dr. W. G. Smith, The University, Leeds.
