296 Deposits containing Flint Implements . [July? 
Great Western Railway. It generally, if not always, rests 
upon an irregular surface of the beds below it, and contains 
stones derived from some other source. 
Op the south side of the Waveney, at Syleham, there are 
good sections on both sides of the turnpike, and these exhibit 
similar false-bedded sands and gravels, which are, however, 
covered by the upper boulder clay instead of by “ trail.” 
Fig. 2 shows a section exposed on the south side of the 
turnpike. A little further west, on the north side of the 
turnpike, is another gravel-pit, showing a similar succession, 
but with the beds of sand and gravel strongly false-bedded. 
In all these sections small pebbles of chalk are very abun- 
dant in the lowest beds. The most remarkable feature in 
the Upper Boulder Clay is the numerous angular patches of 
material quite different from the matrix of brown clay. The 
angular patches of red sand are very peculiar, and difficult 
to explain.

Fig. 2.— Brown boulder clay, with many whole flints, and with angular patches of red 
sand (b), marly clay with small stones (a), and red boulder clay (c). 3. Sands and 
subangular flint, gravel with rounded pebble of quartz, and (in the lowest seams) 
of chalk. 
In a large gravel-pit a little north of Oakley Church 
there is a long section exposed, and in it the Upper Boulder 
Clay, similar to that shown in Fig. 2, at one end of the pit, 
gradually changes into a sandy loam with stones and angular 
patches of sand, not to be distinguished from the deposit 
named “ trail ” in Fig. 1. 
At Hoxne itself, on the east side of Gold Brook, there is a 
gravel pit showing seams of gravel and sand exactly similar 
to that at Syleham, but surmounted by sandy “trail” 
instead of by boulder clay. The gravel is not to be distin- 
guished from the other, being composed like it of sub-angular 
hint pebbles with rounded ones of quartz and quartzite, and 
with many small pebbles of chalk in the lowest seams. 
Notwithstanding this great similarity, Mr. Prestwich consi- 
ders the beds at Hoxne to have been formed by river action
