4 6 Yorkshire Naturalists * Union : Annual Report, 1921. 
Union is not neglecting the problems of plant distribution ; evidence 
is accumulating as to the response of vegetation to soil acidity, and the 
natural sequence of vegetation, which in due course may be expected 
to form a basis for broad generalisation. 
Mr. Wallis’ appeal for a closer co-operation between entomologists 
and botanists, and Dr. Pearsall’s vision of the animal Kingdom being 
involved in ecological studies, indicate the progress of thought within 
the Union ; Mr. Ben Morley’s timely reminder that work on these lines 
has been in progress for many years only emphasises the advantage that 
may be expected if team work can supplement individual effort. 
The secretaries, past and present, are to be congratulated on their 
choice of reporters for the field meetings. 
Mycology (A. E. Peck) : — At the York Excursion (August Bank 
Holiday) the Section was represented by F. A. Mason and A. E. Peck. 
For Report see The Naturalist, October, 1921 (No. 777), with photo- 
graph of Claviceps purpurea Tub, the Ergot of Rye, by E. A. Mason. 
The Mycological Meeting at Castle Howard, October ist-6th, was 
attended by 20 members and friends. A Report will appear in The 
Naturalist. W. N. Cheesman reports finding Coprinus picaceus in Stainer 
Wood, Selby, on October 13th, 1921, which is, I think, only the third 
record for the County. 
Bryological Committee (F. Haxby) : — The work done through 
the past year has shown up well. Weisia curvirostvis C.M. var. 
scabra Lindb. has been found by Mr. Wilson near Sedbergh. Mr. 
Cheetham brought in Bartramia Halleriana Hedw. from Ribblehead 
(Lune drainage). Some advance has been made with regard to our 
knowledge of distribution of many of the smaller of our true mosses . 
Mr. J. A. Wheldon’s ‘ Key to the Harpidioid Hypna,’ and Mr. J. R. 
Simpson’s ‘The Moss Flora of Hagg Wood,’ appeared in The Naturalist 
during the year. Observation is needed as to what effect the hot summer 
has had on the fruiting, etc., of mosses generally. 
GEOLOGICAL SECTION. 
J. Holmes reports ' The zoning of the Millstone Grits has been 
continued during the past year. Members of the Carboniferous Rocks 
Committee attended successful excursions arranged by the Leeds Geo- 
logical Association to Otley and Silsden. Early in the year bads in the 
Worth Valley, near Oxenhope, and at the head of Crimsworth Dean, 
were examined with good results. Marine shales have been noted and 
fossils collected at Marchup, in Wharf edale, at Eastburn, Thwaites and 
Parkwood, near Keighley, in Airedale. The Skipton, Huddersfield and 
Sheffield districts have been re-visited. The shales at Rough Lea on 
the south side of Pendle Hill have also been examined. 
Yorkshire Glacial Committee (J. W. Stather) : — 
Brandesburton, Holderness. — The conspicuous mound half a mile 
south-west of the village, known as Coney garth Hill, has recently been 
extensively quarried by the Beverley Corporation, and fine typical 
sections in morainic gravels and sands are now exposed. 
Cottingham. — A large new quarry in late glacial or post-glacial gravels 
has been opened about half way between this village and Dunswell. 
The cutting into the quarry dips from the road in an easterly direction, 
to a depth of about 16 feet, and the following section is exposed : — - 
1. — Top soil ... ... ... ... ... 1 foot. 
2. — -Irregular clay band ... ... ... 1 to 2 feet. 
3. — Gravel and sand, the gravel consisting \ 
chiefly of waterworn chalk and angular ! 8 feet 
flints, pebbles of sandstone and other j 
rocks being not uncommon ... . . . j 
4. — Sand with carbon streaks (base not seen) 5 feet.
