CKOMER FOKEST-BED, 
beds half-a-mile north-west of Mundesley Church, to Mundesley 
village, an almost continuous section has been examined, though 
the whole of the cliff is never free from talus at one time, as 
landslips occur immediately the buttresses are washed away. 
About 200 yards from the first exposure there was the section 
shown in Fig. 40,

3. Bedded blue loam, full of moss and seeds; Salix polaris, 
Betula liana. 
4. Blue loam mixed with gravelly sand, filling an eroded 
hollow; Succinea. 
j- 5. Laminated clay. 
In the Cromer Memoir horizons 8 and 4 were referred to the 
Upper Freshwater Bed^ but the discovery that they contain 
leaves of the Arctic willows and birches proves that tlie correlation 
was erroneous. The Upper Freshwater Bed is probably entirely 
missing between the Chalk bluffs at Trimingham and the stream 
at Mundesley. 
About a quarter of a mile to the south-east of the point 
where the strata shown in Fig. 40 were observed, the Forest-bed 
is full of derivative cakes of peat from the Lower Freshwater 
Bed, and also proves its estuarine origin by occasional seams of 
mussels. The lithological character of the Forest-bed changes con¬ 
tinually ; but as these variations are only such as occur in most 
estuarine beds, it is unnecessary to give all the details. Three 
furlongs north-west of the Coast Guard Station, Mundesley, the 
base of the cliff is a mass of laminated clay with thin seams of 
sand; but within 70 yards it has entirely changed, by the 
gradual thinning out of the clays, to false-bedded sand. This 
variable character in the strata continues to Mundesley, where on 
the foreshore, in beds rarely uncovered, many mammalian bones 
have been found, including three jaws of Trogontherium, now 
in Mr. Fitch’s collection. The beds in the cliff yield com¬ 
paratively few specimens. 
The relations of the different deposits at Mundesley are some¬ 
what difficult to make out. Great care is also needed to prevent 
confusion of the fossils from the different freshwater deposits;
