60 Yorkshire Naturalists’ Union: Annual Report, 1910. 
Excellent use was made of the Yorkshire Naturalist’s Union 
excursions to further the study of vegetation in Yorkshire, and 
much interesting work was done on the Sphagnum bogs in North- 
West Yorkshire, an account of which was given by Drs. Smith 
and Woodhead in “ The Naturalist ’’ for August. The excursion 
to Kirby Moorside provided a good opportunity for studying some 
of the calcareous dales in that district, as well as the curious 
vegetation of Spaunton Moor. The local knowledge of Mr. Slater 
proved of great service in the study of the vegetation of the dales 
in the neighbourhood of Helmsley. It is hoped that an account 
of this interesting area will soon be forthcoming. 
The joint excursion to Scunthorpe with the Lincolnshire 
Naturalists’ Union enabled the Rev. E. A. Woodruffe-Peacock 
to bring out admirably the changes in the flora of the neighbouring 
moors within recent years, and the Rev. W. Fowler furnished a 
list of characteristic species found in 1854 for comparison with 
those still existing. 
The meeting of the British Association this year at Sheffield 
provided an opportunity for Messrs. Bentley and Snelgrove 
to write a capital account of the more interesting features of the 
flora of the neighbourhood. This was published in the “* Hand- 
book,” and illustrated with excellent photographs of the more 
important types of vegetation.
