 Z. Clayey soil, with a few flints, etc., passing down into — 1 to 2

 4 ' creep,' with an occasional flint in the upper part : some 'race ' : >• 2 to 4 

 penetrated by tree-roots. J 



4, Dark greyish-blue Gault, weathered, but showing bedding in the^ 

 deeper sections, with a weathered ferruginous brownish band, [ 

 about 1 foot thick, in the upper part : ' Belemnites minimus ' ^ to 6 

 and obscure traces of shells : some brown-coated phosphatic ' j 

 nodules : ' race ' in places : passing down into — J 



4 a (in hollows only). Dark gritty clay, with polished lydites, etc."^ 



(up to \ inch in diameter), becoming plentiful downwards : > to 2 

 passing into — } 



3 b (in hollows only). Gritty green sand-loam, with mottled sand}'^ 

 patches : contains a few rough grittj-^ phosphatic nodules, ex- j 

 ternally gre}', and occasional worn slabs of iron-grit : patches of ^ to 2 

 calcareous induration : becomes mixed with ironstone-breccia | 

 downwards. J 



3. Ironstone-breccia and undulating tabular iron-pan, the ' pan,' an"^ 

 inch or two thick, more or less continuous over the rises between j 

 the hollows, but broken up into short lenticles and subangular | 

 partly-worn fragments in the hollows, and set in a matrix of J> i to f 

 ochreous loam with small patches of soft decomposed phos- j 

 phatic limestone and with (in fig. 7 only) occasional rough j 

 giitty phosphatic nodules. J 



3a (in fig. 7). Dirty loamj^ greensand with concretionary induration,") 



partly calcareous, partly phosphatic ; resting sharply with >■ about 1 

 an uneven base on — j 



1. Sands, white, or onlj' slightly lemon-stained, under the hollow in 

 fig. 7, but elsewhere irregularly indurated at the top for a foot or 

 two into bosses or tabular masses of hard liver-coloured iron-grit 

 (1 x), sometimes a quartzite ; the sands around and below these 

 masses are usually stained brown, orange, or buff". 



The Gault in these sections is not thick enough to show any 

 portion in an unweathered condition ; segregations of ' race ' are 

 present in it in places throughout, and tree-roots along the line of 

 the field-fence penetrate it, and sometimes reach into the underlying 

 breccia- series. The upper 3 or 4 feet is massive and structure- 

 less, with an occasional flint or other stone in it, but does not 

 present the aspect of a true boulder-clay, and is probably for the 

 greater part 'creep '-material from the adjacent slopes. Where the 

 Gault is shallow, it is affected by * creep ' to its base ; but in 

 the deeper sections stratification makes its appearance in the lower 

 part, and the lowest layers are charged with smooth bright grains 

 of grit and lydite, this gritty clay (4a) being comparatively thick 

 within the little basins, but thinning away on their slopes. The 

 underlying ferruginous breccia and its associated gritty greensand- 

 loams, variable in detail but well-characterized as a whole, have 

 partly filled the hollows of a ver}'- uneven sea-floor on which the 

 irregular ferricrete masses at the top of the Sands have formed up- 

 standing crags like that seen in the old Garside's pit (fig. 4, p. 11). 

 The scouring away of the unconsolidated material from among the 

 indurated tables has in some places left undercut gutters a foot 

 or two deep between the crags, like those commonly seen on any
