208 Field Meetings, 1907. 
below and beds of a large oyster, Ostrea flabelloides, are very 
frequently met with. 
Both of these beds, the Kellaways Rock and the Oxford Clay, 
are covered, in this neighbourhood, for the most part witha sheet 
of boulder clay, and in places with gravel and drift deposits. 
‘The former being the result of the Ice age, and the latter of rains, 
rivers, and water-flows. Exposures however occur at Welton on 
the east of the village beyond a narrow band of alluvial drift 
which here intersects the Cornbrash. 
One more word as to the position of Welton. The village lies 
on the Great Oolite limestone which extends north and south, but, 
on the north it is covered in parts by an outlying mass of boulder 
clay. On the west it is bounded by a narrow exposure of the 
Upper Estuarine beds,—beyond which, further to the west, comes 
the great mass of the Lincolnshire lmestone, which supplies the’ 
village with water,—while a narrow band of Cornbrash, which, 
near the village, is intersected by alluvial drift, skirts it on the 
east. 
The Fifty-fifth Field Meeting was held at IRBY-ON- 
HUMBER, on June 20th. Waggonettes conveyed the members 
from Grimsby Station to Irby, and in an area of a mile the ground 
was sufficiently interesting to keep the party busy for the day, 
Mr. C. B. Parker a local worker gave his services as conductor, 
such services being indeed valuable, coming from one who knew 
the ground thoroughly. Descending the ‘t Dales,”’ good exposures 
of the chalk were seen from which Mr. C. S. Carter collected 
fossils which he recognised as Rhynconella cuvieri, R. rudensis, 
Cyphosoma Sp. Spine, Terebratula and Inoceramus, Sp., ‘erebra- 
tula gracilis and Holaster planus. J.ower down the dale was seen 
a fine gorge or Fiord of Glacial times and an interesting chalk 
hill known as Rush hill which is capped with gravel, containing 
pebbles of several ignaeous rocks. 
The Botanical report is given by Rev. E. Adrian Woodruffe- 
Peacock as follows.
