(/.) Brick-yard f mile S. of junction with the 



Eoman road. 



13 feet Loam, mottled, yellow red and brown (similar 

 to that seen in road cutting about 2 miles E.) with 

 intercalated patches of white and yellow sand ; pas- 

 sing down into 



1 foot, dark brown very tenacious Clay, which encloses 

 many angular and rolled flints with green-coating, 

 and rests on an uneven surface of (exposed about 9 feet) 

 Chalk with flints, in layers 5 or 6 feet apart, and 

 dipping 3 to S. 7 E. 



Grey sand occurs just S. of this pit (p. 27) and overlies 

 the loam.

 About 4 feet (not bottomed). Pale grey sand, very clean

 probably indicates a change' at no great depth to a de- 

 posit of loam or clay.)
