VOL. XIV. (3) HOLOCENE DEPOSITS 197 
pebbles ; whilst in the other pit, in the same field, coarse 
sand predominates. 
In the west bank of the river, due west of the Barley 
Mow Inn, Alluvium was visible resting upon low-level 
gravel; whilst at the entrance of the Clifton Hampden 
lock, it rested upon shell marl, and this latter upon the 
gravel. Similar phenomena were observed in the left 
bank of the weir-stream some 800 yards west-south-west 
of Long Wittenham Church. About 300 yards to the 
north of Appleford Church is a gravelly arenaceous 
deposit, crowded with shells and capped by dark brown 
Alluvium. At the base of the Alluvium, vertebrate re- 
mains—of existing species—were obtained, and with them 
was much charred wood. 
In this section the Alluvium rests upon the gravelly 
shelly deposit, and no shell marl—as regards lithic struc- 
ture—was observed. It is difficult to correlate Holocene 
deposits: all that can be said is that it occurred imme- 
diately below the Alluvium, and that in the original section 
shell marl occupied that position.
