The water must come from the Lower Greensand. 
J. Manseren referred to a bill promoted by the Croydon 
Corporation in his address, ‘‘The Law and Allocation of Under- 
ground Water,” at the Engineering Conference of the Institution 
of Civil Engineers.*

H. W. Moncxrron described ‘‘some Gravels of the Bagshot 
District.”+ This tract includes contiguous parts of Berkshire, 
of Hampshire, and of Surrey, and is therefore of interest to 
Surrey geologists. 
The presence of large blocks of greywether-sandstone in gravel 
of Chobham Ridges and of other places is treated of at length, 
and this is an analogous occurrence to that of the blocks of 
pudding-stone in gravel around Croydon, the stones in both 
cases being for the most part the relic of some old Tertiary beds, 
though the author thinks that some are consolidated gravel. 
The Farnham Gravels are also noticed, and are taken to be 
all River Gravels, although on the Geological Survey map some 
of the patches are classed simply as Hill Gravel of doubtful age.| 
. The author’s conclusion is that there is ‘‘ no evidence of the 
presence of the sea in this district during the Drift period,” but 
that there is ‘‘ ample evidence of ice-action, and this evidence is 
more or less present in the gravel of all levels,” and that the 
gravel ‘“‘ practically coincides in age with the duration of the 
_ Glacial Period.”’ 
A. BE. Saurer’s paper, ‘‘Pebbly and other Gravels in Southern 
England,’’} refers to Surrey, under the headings High Level or 
_Early Drifts (pp. 266, 267); Lower Plateau and Glacial Drifts 
(pp. 271-274); The River Drifts (pp. 275, 276). 
T. Lereuron, in an account of an ‘‘ Excursion to Godalming,’’§ 
continued his work on the Lower Greensand, noting sections of 
Bargate Stone and Pebble Beds, and of clay. He objects to the 
Fullers’ earth of Nutfield, &c., being classed as Sandgate Beds. 
A report of an ‘‘ Excursion to Kingswood and Walton-on-the- 
Hill,’’|| describes cuttings on the Chipstead Valley Railway, 
which show various Drift beds over Thanet Sand and Chalk, as 
well as a very irregular piped junction of Thanet and Chalk. 
The gravel of the Heath is also noticed. 
A short note of an ‘‘ Excursion to Upper Warlingham and 
Worms Heath,’ alludes to the Valley Gravel at the former
