 of the sections dealt with in this paper.

Thiclcness in feet. 

 Brown clayey- soil, containing a few flints and drift-stones,' 

 passing down into structureless clay, j)robably ' creep,' with an 

 occasional stone : passing down into — 

 Disturbed and rearranged pale grey-blue Gault, mostly or wholly^ 

 'creep,' blocky and joint\', with crumbl}' structure and no clear f 

 bedding: some strong fresh slicken-planes : more or less 'race' t 

 throughout, plentiful towards tbe base. J 



This material cuts out the bedded Gault (4) at the west side 

 of the section. 



4. Darker greyish-blue Gault, with platy structure and bedding,"^ 

 somewhat disturbed : the uppermost 6 inches paler, with brown 

 rusty weathering and much ' race ' ; lower part, green-mottled in 

 places : ' Belemnites minimus ' and obscure traces of other fossils. 



4 a. Basal layer of gritt}' Gault, 2 to 3 inches thick at the eastern end, 

 but thins on the rising slope westwards : sprinkled with small 

 pebbles, up to half an inch in diameter : red streak at the base 

 where resting on iron-pan. 



3. Iron-grit breccia, ochreous ; with tabular liver-coloured iron-pan^ 

 1 to Ig inches thick, uneven and wrinkled, fairlj' continuous at 

 the top and in irregular lenticles below ; associated with worn 

 lumps and slabs of ironstone, lenticles of pebbly glauconitic 

 loam, pale decomposed calcrete-patches with obscure traces of |> 

 fossils, etc., as in Nine Acre and Miletree pits. Upper surface 

 of iron-pan worn and abraded, with patches of pebbly glauconitic 

 grit in the hollows; and similar material, more coarseh^ pebbly, 

 (3 a) at the base of breccia in eroded hollows of underlying beds.^ 

 A smooth polished cuboidal block of chert, 3 x 3 x 2 inches, 

 embedded in the glauconitic grit, was found at + , but no other 

 pebble more than an inch in diameter was seen. 

 Evenl3'-bedded streaky and mottled ashy-grey silts and silty'^ 

 loams, with ferruginous streaks ; towards the western end, a f 

 1- to 2-inch streak of rather dark glauconitic sand : uneven sui'- T 

 faces of erosion both at the top and the bottom : resting sharply J 

 on — 

 Silver sand, mostly white and of medium grain ; with some thin 

 tabular lenticles of imperfectly-developed concretionary iron- 

 stone, passing in places into hard liver-coloured stone : worked 



A sump sunk to 10 feet below the floor of the pit shows similar, 

 but rather finer, sand with a few streaks, up to half an inch 

 thick, of fine greasy-textured grey clay, which are wrinkled and 

 twisted like the iron-pan in (3).
