The following notes are furnished by Mr. C. Reid: — 
Marly chalk is seen near Alciston, and in the escarpment south¬ 
west of that place there is an exposure of massive whitish chalk 
surmounted by the Belemnite Marl. At Wilmington the central 
part of the Lower Chalk appears to change its character, and 
to become a massive firm grey chalk, which forms a distinct 
feature along the escarpment, sometimes more conspicuous than 
that of the Mel bourn Rock above. This facies continues eastward 
to Eastbourne. 
Close to Folkington Church there is a pit in this massive grey 
chalk, and 300 yards to the north-west pink chalk is seen in the 
road. About 50 feet of the same massive chalk is well shown in the 
Ocklynge Chalk Pits, and Chalk Marl can be seen in the road below. 
The Belemnite Marl is seen in the chalk pits at Ash, and also 
near Willingdon, near Southfields above the Grove, below Butts 
Down, and in the chalk pits above Jas Combe. As the base of the 
Chalk is also exposed near Willingdon, the difference between the 
heights of these exposures, as shown on the six-inch maps, gives 
about 200 feet as the approximate thickness of the Lower Chalk. 
This estimate of the thickness of the Lower Chalk is confirmed 
by two borings made at the Star Brewery in Old Eastbourne, the 
site being about 50 yards from the church, and not far below the 
horizon of the Belemnite Marl. The older boring was made by Mr. 
R. B. Paten, of St. Albans, and is said to have traversed 202 feet of 
Chalk and Chalk Marl. A second boring was made in 1896, and 
we are indebted to the Rev. W. R. Andrews, for the following 
particulars obtained on the spot: — 
ft. 
Chalk --------- 200 
Greensand and rock.47 
Gault clays -------- 261 
Greensand at - 508 
B.—The Coast Section . 
We now come to the coast section, where a good and clear exposure 
of the Lower Chalk might be expected. This, however, is unfortu¬ 
nately not the case, for the cliffs between Eastbourne and Beachy 
Head are broken by landslips, and show also signs of much squeezing 
and faulting, so that it is impossible to take a continuous section. 
Before the sea wall was built below the Wish Tower there was a 
good section of the lowest beds, and the following account of it has 
been communicated by the late Rev. H. E. Maddock, who lived for 
some years at Eastbourne, and collected largely from the Lower 
Chalk:- 
ft 
Chalk with green coated phosphatic nodules (Cast Bed) - 6 to S 
Chalk Marl with Am. [bcliloenbachia] varvans and 
“ Brachiclites ” at the base - about 30 
Chloritic Marl with phosphate nodules - about 4.1
