NATURALISTS AT BARTON-ON-HUMBER. 
THE members of the Yorkshire Naturalists’ Union, with the 
members of the Lincolnshire Naturalists’ Union, investigated 
that section of the North Lincolnshire shore between South 
Ferriby and Barton-on-Humber, on Saturday, July rst. 
On arriving at Barton the party divided into sections, 
according to the nature of their respective investigations, 
and joined again at the close of their day’s work to record 
the results. The geologists had the guidance of Messrs. T. 
Sheppard and J. W. Stather. 
They were particularly fortunate in seeing a recent exposure 
of considerable importance. This occurred on the bank of the 
estuary near South Ferriby Hall, and showed a part of the 
original pre-glacial bed of the Humber, recently made visible 
by a change in the course of the river. Another interesting 
feature was an exposure in Neocomian or Kimeridge Clay, 
which had recently been discovered by the secretary of the 
Union. This occurred quite close to the previously-mentioned 
section, and the large cake-like nodules which occur in the 
clay were all similarly striated on their upper surfaces. A 
number of Belemnites and other fossils, almost identical with 
those found in the Speeton clay in Filey Bay, were secured. 
The party also secured, from the chalk, teeth of two species of 
shark (Ptychodus and Lamna) ; vertebre, and other bones of 
fishes, sea-urchins (Dziscotdea cylindrica), and various Brachio- 
pods, etc. 
The botanists had for their leaders, the veteran, the Rev. 
Canon W. Fowler (Winterton), and Mr. J. F. Robinson (Hull). 
The old chalk quarries, the woods, and the Humber mud- 
flats proved to be charming botanical gardens, and the party 
saw the Bee orchis flowering in one of its few favourite localities. 
The teasel was also quite common-—doubtless a survival from 
the time when this plant was grown for use in the Bradford 
stuff works. For mycology, Messrs. W. N. Cheesman (Selby), 
and C. Crossland (Halifax), were responsible. This section 
continued its work over the week-end. 
The Fungi collected and brought to the meeting were few, 
but Mr. Crossland and Mr. Cheesman, who remained at Barton 
till Monday, had good success at the Blow-Wells and Ferriby 
Chalk Quarry. Crepidotus Ralfsit, not before recorded for 
the county, was found on decaying wood in the quarry, and 
about thirty other species on the way to and from, or at, the 
Blow-Wells, including Omphalia gracillima,.Pholiota precox, 
Soppittiella sebacea, Dasyschypha virginea, and D. fugiens, Pert- 
conta byssotdes, Stemonitis fusca, and Lycogala epidendrum. 
For general entomology Mr. C. W. Mason (Barton) was 
responsible, but the weather was not favourable for his depart-
