found the implements, and they are now very seldom met 
with, — so seldom that none of the men working at the clay- 
pit when I was there had ever seen one. 
To the west of the road, in the pit that has been opened 
in Sir Edward Kerrison’s park, a section of the beds has 
been exposed at the point marked E in general section, as 
shown in Fig. 8. The most remarkable feature in the 
section is the occurrence of the upper clay, 2 in sedtion, 
containing angular patches of red sand, like that seen in 
the “ upper boulder clay ” of other parts of the distridt. I 
cannot help thinking that if this sedtion had been open when 
Prof. Prestwich examined the deposits he would have been

Fig. 8.— 1. Sandy “ trail” with flints graduating downwards into sand, filling pipes in 
clay below. 2. Unstratified yellow clay, containing isolated angular patches of 
reddish sand. 3. Whitish sand with a few scattered pebbles, sometimes changing 
into reddish sand, like that of the patches in the clay above. 4. Yellowish brown 
clay (“ red brick earth ”), unstratified at top and graduating downwards into lami- 
nated calcareous clay. 
led to modify his opinion respecting the relation of the depo- 
sits to the glacial period. I myself believe this clay to be 
the upper boulder clay, and the sand with pebbles below it 
to be the “ middle glacial sands and gravels.” 
To trace the “ red brick earth, 5 ’ 4 in section, down towards 
the lower boulder clay, I set some men to work, and had a 
shaft sunk — at the point marked B in general section — to a 
depth of 1 7 feet from the top of the surface soil, and obtained 
the section shown in Fig. 9. The most noticeable feature in 
this section is the thickening out of the false-bedded sands 
and gravels, their resemblance to the middle glacial series, 
and the absence of the “white brick earth,” 7 in section. 
In a pit a little east of this, Prof. Prestwich and Mr. John 
Evans found a flint implement in the gravel bed, 3 in 
section.
