173 
long, with a varying depth of bottom, from 4 feet to 12 feet, consist- 
ing of numerous pockets. This was filled in all round the edge of the 
pockets with black material, clayey soil, and flints partially cemented, 
having a yellow tinge ; streaks of stratified chalk gravel and flints, 
were visible, in places, running across the face, and the whole was 
covered with two or more feet of rain-wash. 
At the next cutting but one from Euthorpe, distant about f mile, 
the grey chalk put in its appearance in a slight cutting, 5 feet, on 
the right hand side. Here a dark-coloured band of marly matter, 
one foot thick, in the form of an arc of a circle, depressed in the 
centre to the line of rails, and extending for over 30 yards, was 
visible, followed by gTey chalk, 3 feet, and a second concentric band 
of grey marl one foot thick. It is probable that this represents the 
zone of BelemnitelJ/jL plena, which divides the middle from the lower 
chalk. The same upper bed was represented in the next cutting on 
the left, only darker in colour, and contorted. The lower marl was 
absent. 
The railway next crosses a slight valley. On the left a well was 
sunk in the bottom, cutting tlirough Red Chalk some wa)' down ; 
whilst, on the right, 50 yards distant, there is a slight cutting in Red 
Chalk, evidently the Hunstanton limestone, showing a fault of some 
60 or 70 feet. ^Ir. G. "VV. Lamplugh tells me that he noticed a 
yellow baud below this red chalk, which may be taken to represent 
the 6 inch bed of Neocomian to be seen at Acklam Brow, and which 
I described in my paper on the Red Chalk, communicated in 1878, 
in a section at Warter Brickyard, as one foot of orange-coloured 
clay," between the Red Chalk and Lias. 
From this point to Market Weighton the beds consist of Lower 
Lias ; all else is absent. 
The next cutting, opposite to Mr. Leighton's house at Good- 
manham, presents a curious section, which I give in detail : —
