THE CRETACEOUS ROCKS OF BRITAIN. 
here is in its natural order ; most of the higher beds seemed to me 
to be slipping over the lower ones. . . . The central part seemed 
fairly solid and continuous. I give the following section for what 
it may be worth : — 
Feet. 
Rubbly chalk and soil with marked indications of the 
Belemnite marls at the base- ------ 2-3 
Face obscured by talus, chalk appeared broken up [and has 
probably slipped] - - - - - - - 10-12 
Hard roughish chalk, weathering into platy pieces, thin marl 
bands -----------3 
leather soft marly pink chalk - - - - - - - 
Hard rough chalk, with green-grey marl bands 5 
Totternhoe Stone.— Hard grey chalk, rather nodular, with 
green-coated nodules at the base (fossils) - - - - Ij 
About 27 
The marly pink band is seen again in Uncleby Dale, but there is 
no clear section. 
The Totternhoe Stone and some of the overlying chalk is 
exposed in the slipped mass at Leavening above the Chalk Marl 
(see p. 229). The details given by Mr. Hill are as follow : — 
ft. 
Chalk rubble, much broken up- - - - - - 6 
Whitish chalk, not hard, much broken, but apparently in 
place, irregularly bedded, with strongly marked buff- 
coloured bands of marl - -- -- -- 9 
Whiter chalk, less marly than hard. 2 |- 
Grey Bed .—Hard grey nodular chalk, clearly distinguishable 
from that above and below -------2

No pink-coloured chalk was seen here, but a yard or two beyond 
the point where the section ends, rubble of pink chalk is seen; its 
exact position in the section, however, was not determinable. Pink 
chalk overlying greyish chalk is also seen about a quarter of a mile 
east of Swinham. 
Mr. Hill thinks that the thickness of the Of. splicer icus zone 
in this district is about 35 feet, but there is no means of measuring 
exactly. Eastward, along the northern brow of the Wolds, it 
becomes thicker, and a fairly good section of it is exposed in the 
side of the combe west of Canton Hall. The succession is given 
as follows: — 
Middle Chalk, zone of Inoc. mytiloides , -

/-one or | only intervals ------
