YORKSHIRE NATURALISTS' UNION. 
the routes were arranged so that as much as possible of the 
escarpments and the moorland plateau, including Black Hamble- 
ton, could be traversed. The results were most satisfactory, as 
the district is especially suited for showing within a short distance, 
the chief features of the vegetation of north-east Yorkshire. 
During the year the Convener and Mr. Elgee have carried the 
map survey of north-east Yorkshire almost to a finish, although 
some time must elapse before it can be published. A short 
account with a \ egetation map on a small scale is included by 
Mr. Cotsworth, York, in a publication on the district. 
Dr. Woodhead reports that the survey he is carrying out in 
Upper Wharf edale, has made good progress during the year. 
A new map and memoir by Dr. C. E. Moss (Cambridge), on 
the vegetation of the Pennines of south-west Yorkshire and north 
Derbyshire is in preparation, and will be issued by the Board of 
Agriculture. 
" The Naturalist " for 1908 contains two papers relating to 
Botanical Surveys : — Dr. Woodhead gave an account of " Plant 
Geography and Ecology in Switzerland " (May and June 1908), 
which will enable botanists to see how important a part these 
branches play in the Botany of Switzerland. Mr. Mackinder's 
address (March 1908), contains references which indicate the 
important place which geographers give to botanical surveys. 
Another interesting piece of work is that of Mr S. Margerison, on 
" The Vegetation of some Disused Quarries," now appearing in 
the Bradford Scientific Journal. 
In conclusion, 1 would like to add a personal note, expressing 
my regret that my removal to Edinburgh will mean a less active 
service to this Committee. It was in many ways a charge handed 
over to my care by the Y.N.U., and I may candidly admit that 
it has served as an important aid to my own work. Yet I trust 
that the botanists of the Union, especially the younger race, will 
feel that the botanical surveyor's point of view has added new 
interest to out-door observations, and to systematic botany, 
which is the foundation of all open-air botany
