YORKSHIRE GEOLOGICAL SOCIETIES. 
(1) Transactions of the Hull Geological Society, Vol. VI., part 
4, for the years 1910-21. Edited by T. Sheppard, M.Sc., F.G.S., Huli,. 
1922, with reproductions of nine photographs and numerous illustrations, 
(2) Transactions of the Leeds Geological Association, Part 
XVIII. (1913-20), published April, 1922, with six photographic repro- 
ductions and many other illustrations. 
The activities of the Huli and Leeds Societies were naturally affected, 
by the war, but the members succeeded in doing good work. The papers 
are mainly concerning local deposits, but many of the results are of far 
more than local interest. 
The Transactions of the Hull Society open with a paper by the Editor 
on Early Humber Geography. In this, Mr. Sheppard, with a happy 
combination of geological, geographical and historical knowledge, 
criticises J. R. Boyle’s ‘ Lost Towns of the Humber,’ and argues that 
certain places, now destroyed, which Boyle regarded as being in the- 
Humber, were really outside it, and that any great amount of erosion 
inside is unlikely. 
Messrs. Crofts and Pawley describe ‘ Sections made during the ex- 
cavation of the King George Dock, Hull.’ These are generally similar 
to those of the Alexandra Dock, previously described. Details of the' 
shell-bed and peat connected with the warp, and of the underlying glacial 
deposits consisting of boulder clays with intercalated sands and gravels,, 
are given . 
A paper on ‘ New Sections near Melton, North Ferriby, Yorks.,’ by W_ 
5. Bisat, is of much interest. The glacial beds are stated to be marginal 
deposits of the North Sea ice-sheet. A bore was sunk down to the Upper 
Lias. It shewed some very remarkable occurrences, including the 
presence of a true Carstone (the first record of this in Yorkshire), absence 
of the Speeton and Kimmeridge Clays, and development of the Ampthill 
Clay type of Corallian strata. 
Under ‘ Notes of Excursions,’ We find record of a boulder from the 
Holderness coast, which Dr. Milthers, of the Danish Geological Survey, 
recognises as Dalecarlian Gronklitt porphyrite. 
Mr. J. W. Stather records ‘ A new section in the Oolites and Glacial 
Deposits near South Cave.’ A chalky rubble, with no far -travelled, 
boulders, rests on an uneven surface of Millepore oolite in situ. Above 
the rubble is a mass of displaced Millepore oolite (with possible Lias 
Clay beneath). This mass is 300 feet long and 12 feet thick in places, 
and must have been carried over the rubble by a transporting agent, 
presumably glacial. Mr. Stather proposes later to describe thus very" 
complex section in greater detail. 
There follows another paper by Mr. Sheppard, ‘ Hull’s Water Supply,” 
giving record of a boring at Dunswell, between Hull and Beverley. It 
passed through about 13 feet of superficial deposits, 23 feet of glacial 
accumulations, and 7 to 8 feet of flinty gravel resting on comminuted 
chalk, which itself reposed upon solid chalk. 
A list of lectures and papers from 1910 to 1921 gives ample proof o£ 
the activity and varied interests of the Society. 
The Leeds Transactions contain four papers and abstract of a fifth.. 
This abstract has some useful notes on ‘ Creeps,’ by Mr. H. Preston. 
One of the papers, ‘ Peat Problems,’ by Miss E. D. Whitaker, treats of 
Peat from the scientific and commercial standpoints. The subject might 
with advantage have been treated more fully. There are some original 
observations on a deposit at Harwood Dale Bog, in North-east Yorkshire,, 
and on peat-ash. The other papers are concerned with Coal Measures- 
and Millstone Grit in and near Leeds. The first paper, by Dr. Gilligan,. 
describes a bore hole at Mean wood through Lower Coal Measures and 
Rough Rock into the second grit.. A photographic plate shews samples
