220 W. Keeping and C. S. Middlemiss—Sections at Cave. 
Fossils are not abundant, but Terebratula semiglobosa, and portions 
of Inoceramus occur, and Belemnites minimus is common, especially in 
the nodular beds. : | 
Above this comes the Grey and Lower White Chalk of the usual 
characters, but about 380 ft. above the true Red Chalk there is a 
pink band of about a foot thick resembling those at Speeton and 
Louth, Lincolnshire. A few irregular pale-coloured flints occur in 
the Lower Chalk, and the joint surfaces are in many places black- 
ened by a deposit of manganese. Thin bands of Fullers Earth occur 
in the Lower Chalk. A remarkable set of beds of an argillaceous 
and carbonaceous character oceurs in the White Chalk 25 ft. above 
the Pink Chalk above mentioned. The total thickness is about 8 ft., 
consisting of three divisions, the lowest being a pale yellow lami- 
nated and jointed marl (1 ft.), the upper zone a similar rock usually 
greenish or brown in colour (1ft. 3in.), and the central band a dark 
carbonaceous shale or black coaly shale with fragments of plants. 
We now propose briefly to notice one or two other exposures of 
the Kelloway Rock seen between Market Weighton and the Humber. 
The first and only exposure along the escarpment south of the 
railway cutting is a sand pit by the road-side at South Cave. It 
is about 10 ft. high and embraces the uppermost 10 ft. of the unfos- 
siliferous sands, crowned with a thin portion of the upper hard 
fossiliferous bed. The sands are, if anything, slightly more irony 
than in the cutting, and though indications of concretionary action 
are present, no nodules occur. These sands were formerly supposed 
to be Lower Greensand, from their great similarity to those of that 
age in Lincolnshire. 
South of this point the Kelloway Rock is not found, and the well- 
marked ridge comes to an end with a slight trend to the south-east, 
indicating that here with a change of strike the beds are completely 
overlapped by the Cretaceous series. 
In an opposite direction, north of the railway cutting, and across the 
valley in which Drewton lies, the position of the Kelloway Rock is 
shown by a well-marked ridge, and there is a slight exposure of the 
pale sands with concretions in a field some few yards below the 
house called ‘“‘ Kettlethorpe”’ on the Ordnance Map. 
Beyond Kettlethorpe the line of outcrop follows the road to 
Market Weighton for about two miles, and then runs easterly, forming 
a V-shaped curve, owing to the wide valley in which Newbald lies 
having been excavated across the strike. The return curve shows 
a quarry in the Kelloway Rock under the hill-side north of the town. 
The base of this quarry is of interest, inasmuch as it exposes 
lower beds than we have hitherto met with. At the top is about 
5 ft. of the usual red-brown rock full of the usual fossils; below 
that 20 ft. of the pale sands with incipient concretions, and a few 
well-formed ones in the upper part, but without the singularly pure 
development below of the micaceous well-jointed sand rock. Beneath 
these about 5 or 6 ft. of the rock becomes gradually more clayey, 
and an iron staining again sets in, giving the rock a pale-brown 
colour. Here too the rock becomes fossiliterous, though few of the 
fossils are well preserved.
