authority of the then keeper. Personally, I never saw Herons tackle 
such large fish. Our picture gives a characteristic view of the ponds 
with the Gulls standing on the branches of a dead tree. We are 
indebted to the kindness of Mr. Frederick Boyes, of Beverley, for 
leave to reproduce this view from a negative taken by Mr. Johnson 
C. Swailes, of the same town. 
After seeing the birds the large party broke up into sections for 
field work, Mr. John Beaulah, of Raventhorpe, leading the con- 
chologists to the most productive ground; Mr. Charles S. Holgate, 
of Low Risby, the entomologists ; Mr. F. M. Burton, the geologists ; 
Mr. John Cordeaux, the vertebrate zoologists ; and the Lincolnshire 
Secretary the botanists. 
Mr. John Cordeaux, M.B.O.U., on behalf of the Vertebrate 
Section, writes:—From the fact that the members of the two Unions 
were not allowed to visit the most favourable localities for seeing 
the rarer birds and wild fowl, very few species were observed during 
the day. The visit to the gullery at Twigmoor afforded much pleasure 
to the assembled naturalists. Immense numbers of the Black-headed 
Gull were found nesting around the ponds, and these on the 
approach of the visitors rose in one vast flock, the winnowings of 
thousands of wings together resembling the sound of many waters 
or the distant roar of a waterfall. When alighting hundreds perched 
for the time on the neighbouring trees. Most of the eggs were in 
an advanced stage of incubation—in some nests the tiny down-clad 
chicks had only just emerged from the egg. Numbers of young; 
from a day or two to a fortnight old, were wandering in groups along 
the margin of the pond or afloat on the water. On the chief pond 
were some Coots and Waterhen, but no Sheldrake were seen, 
although several pairs were nesting in the neighbourhood. On 
Manton Common several Wheatears were seen, also a few Stock- 
doves and some thievish Daws; these latter, like the Stockdove 
and Wheatear, also nesting in the rabbit burrows. During the day, 
but chiefly in the Manby Woods, the Nightingale, Garden Warbler, 
Blackcap, Redstart, Wood Wren, Willow Wren, Chiffchaff, Common 
and Lesser Whitethroats were seen or heard. 
The Appleby, Broughton, Manton, Raventhorpe, Scawby, and 
Twigmoor woods, commons, ponds, ‘ flashes,’ bogs, ‘ damp spots,’ 
and ditches are, when the number and rarity of some of the species 
are taken into account, the richest botanical ground in Lincolnshire ; 
and have been the happy hunting-ground of botanists for over 4 
hundred years. The following is a concise list of thé rare species 
to be found on the ground west of Brigg figured in our map, and of 
which proof specimens are in the British Museum or Lincolnshire
