738 REPORT—1899. 
scarp of the chalk downs. Its range in other directions is unknown, and awaits 
further investigation. To the south of this anticline the palzozoic floor is 
probably composed of pre-coal-measure rocks. If, however, the coal measures do 
occur, they are buried under such great thicknesses of superincumbent rock— 
largely sands and loams full of water—that it will be difficult to work them. 
We know now by experiment not only where to seek, but also where it is 
advisable not to seek for the coal measures. The difficult problem of the buried 
coal measures in South-eastern England, now being worked out by private enter- 
prise, is likely to add greatly to the resources of this country, as it has already 
added to the wealth of geological Inowledge.

— 3, Note ona Boring through the Chalk and Gault near Dieppe. 
By A. J. JuKes-Browne, L.A., F.GS. 
The following particulars of a boring for water made at Puys, near Dieppe, in 
1898, have been communicated to me by Messrs. Le Grand & Sutcliff, the site of 
the boring being about 45 feet above the sea, and not more than 50 yards from 
high-water mark.

The ‘chalk without flints’ will correspond to our Lower and Middle Chalk, 
and must include chalk which, on the English side, generally contains a few flints. 
The two metres of greensand and sandy clay at the base of this is probably what 
is generally known in England as Chloritic Marl, the zone of Stawronema Cartert, 
which is 15 feet thick at Folkestone, but less beneath Dover. 
No sandy beds referable to ‘Upper Greensand’ are recorded, and the Gault 
seems to be entirely represented by clay, as at Folkestone and Dover. The black 
sand with pyrites should doubtless be regarded as the basement bed of the Gault, 
but the clean quartzose sand below is probably the equivalent of the highest part 
of the Vectian or Lower Greensand. 
A good supply of water was found in these sands, rising to 12 feet above the 
surface of the ground. 
From this boring it would appear that the Folkestone and Wissant facies of 
the Gault extends southward as far as Dieppe, a distance of about 52 miles.

Staffordshire, and its bearing on concealed Coal-fields. By Watcot

[Communicated by permission of the Director-General of the Geological Survey.] 
There is every reason to believe that in the near future the supplies of coal 
lying beneath the Red Rocks of the Midland counties will have to be relied upon 
to meet the increasing demand. 
Workable seams of coal have been met with at reasonable depths beneath the 
Red Rocks surrounding the South Staffordshire coalfield, but there remain large 
areas lying between the known coalfields of Shropshire, North Staffordshire, and 
Nottinghamshire, which have not at present been explored. Within this region,
