HARMER : FIELD EXCURSION TO CROMER, ETC. 
alluded to (PL XLVII.) was examined, the identity of the boulder- 
clay to that of Pakefield being apparent to everyone.* A short 
stay was made at a well-known section at Tharston Furze Hill, 
near Forncett, which shows the fine white micaceous sands of 
tlie Crag (there unfossiliferous), with pebbh^ gravel overlying 
them, resting on the undisturbed surface of the Chalk ; Chalky 
Boulder-clay on Middle Glacial sand occurs in the immediate 
vicinity. A large Xeocomian boulder was noticed by the road- 
side near this pit. 
From Tharston the party was driven to Wymondham, on the 
old turnpike from Norwich to London, and eight miles S.W. 
from the former, where some extensive excavations in " Cannon 
Shot " gravel, like that of Mousehold Heath (PI. XLVI.), were 
examined. At Wymondham, however, ?.nd in the surrounding 
district, these gravels rest upon Chalky Boulder-clay. They 
are almost entirely composed of flint, but in a heap of rejectamenta 
one or two small boulders of dolerite, quartzite, and Carboniferouf> 
Limestone, and one of rhomb-porphyry, were found. 
Taking the old coach road to Norwich, a slight detour was 
made to Cringleford, a picturesque village on the river Yare, 
for the purpose of examining the writer's collection of Miocene 
and Pliocene fossils. At this spot, moreover, evidence of the 
existence of Chalky Boulder-clay beneath the alluvium and the 
paloBolithic gravels of the shallow valley of the Yare, and of the 
occupation of the latter by ice, during the L^pper Glacial period, 
was pointed out. 
Here the excursion terminated, and the writer took leave 
of his Yorkshire friends, who had proved themselves the most 
pleasant of comrades and the most courteous of critics. 
Forsan et haec olim meminisse juvahit. 
* Sections of boulder-clay of similar character to that of Forncett 
and Pakefield occur in the region intervening between these two places.
