THE YORKSHIRE NATURALISTS’ UNION 
AT WITHERNSEA., 
Ow the occasion of this year’s visit to the coast-line, Withernsea 
being the centre of operations, the Union were much indebted in 
every way to their Hull members, both as regards the assistance 
they rendered to the Secretaries in making the preliminary arrange- 
ments and as regards their taking a full share in the excursion 
itself. The excursion was planned for the investigation of that 
portion of the Holderness coast which extends from Sand-le-Mere 
southward to Dimlington High Land. The day being Bank Holiday 
Monday, the 1st of August, and there being but one way of access 
to the district, all members had to mingle at Hull and its suburban 
stations with many thousands of day trippers travelling by a number 
of relief trains which did not stop at intermediate stations. One 
unexpected result of this was that it was found impracticable to 
carry out the arrangements for a party to investigate the woods at 
Old Winestead, it being impossible to ascertain in the crowded 
Stations at Hull either what members wished to join that party or 
which of the trains was the ordinary one which was to stop at 
Winestead station. 
On arrival at Withernsea station the other two parties which 
had been arranged set off after a short delay. One of these was 
as customary the geological one, and was in charge of Mr. Alfred 
Harker, M.A., F.G.S., who conducted his followers southward to 
Holmpton, and thence along the cliff to Dimlington, returning 
from thence to Withernsea along the beach, the tide being favourable, 
low water being at 2 p.m. A small party of naturalists followed 
them at a respectful distance and on the return accompanied them 
for a portion of the distance. Both of these parties were alike 
interested in the sections of the lacustrine beds shown in the cliffs 
of Boulder Clay, evidencing the former existence of a chain of lakes 
of which Hornsea Mere is now the only one left, and in which, 
thousand of years old as they are, are to be found in great profusion 
the shells of various freshwater mollusca and the remains of fish 
of species now to be found alive in that Mere. 
The second main party, consisting of botanists, conchologists, 
and entomologists, under the energetic leadership of Messrs. F. W. 
Fierke and T. Petch, B.A., of Hull, and Mr. Charles Waterfall, 
of Welton, went northward in the direction of Tunstall, and was 
strong and numerous. They worked along the top of the cliff 
as far as Sand-le-Mere, and then dredged the Keyingham Drain 
Oct. 1892.
