Vol. 51.] GREENSAND OE EAST SURREY. 115 



The southern face of the same pit shows 16 feet of blue Fullers 

 Earth below the series of beds last mentioned. Beyond the next field 

 to the east are the Park Works, where the Fuller's Earth is worked 

 at the surface on the 400-foot contour. This is the pit referred to 

 by Meyer and Whitaker, and in the lane to the south is the section 

 mentioned by Meyer and Topley. The ' layers of sandstone ' of 

 Meyer I have already said are chert-beds, but I can add nothing to 

 that author's description of the underlying Pebble-beds, which are 

 well shown now ar. the junction of Handy Lane. For Meyer's next 

 beds ' light ash-coloured and ferruginous sands becoming slightly 

 argillaceous as they descend, 50 to 100 feet,' I can give the following 

 section (somewhat imperfect owing to the unsatisfactory condition 

 of the cutting) : — 



Mottled buff sands, becoming clayey below, sand usually 

 fine. 



Layer of sandy chert 6 inches to 1 in. 



Buff clayey sands. 



White and grey glauconitic sandstone, with dark clayey 

 inclusions ; not calcareous so far as observed, but pos- 

 sibly belonging to the Kentish Eag. [Kentish Kag of 

 Meyer] (a). 



The last are the lowest beds seen in this lane, but where last 

 exposed they are still 100 to 130 feet from the top of the Atherfield 

 Clay, which lies between 200 and 230 feet below the Pebble-beds. 



In this series of sections I describe everything between the 

 Pebble-bed at the base of the Folkestones and the lower Pebble-beds, 

 both inclusive, as Local Group 1, and hold that they are practically 

 on the same horizon as the Bargate Beds of Godalniing, thus 

 in part agreeing with Meyer. The sands below appear to me to 

 belong to Local Group 4, possibly containing a northerly thinning 

 of deeper-water beds, formerly laid down to the south. 



At the farther end (east) of the village of Nuffield another hollow 

 lane, termed on the 6-inch map Cooper's Hill, runs south, parallel 

 to the one last described. Top of the section about 460 O.D., dip K, 



White speckled cherty sandstone, with occasional sugges- 

 tions of marked chert-layers, becoming rubbly near the 

 surface 6 feet seen. 



Olive-white pebble sandstone (pebbles with usual Bargate 



character), a well-marked bed .' 4 feet. 



Pebble-beds — sands, hardened in places, much false- 

 bedded, and containing layers of characteristic Bargate 

 pebbles in sandy matrix — in places highly glauconitic 

 layers, with few or no pebbles 10 to 12 feet. 



Coarse false-bedded sands (Sandgate Beds of Meyer x ) ; at 

 the top they differ little from the finer Pebble-beds, 

 except that they are more uniform, are mottled red- 



and- white in colour, and do not contain pebbles About 20 feet 



seen. 



Lower down this lane false-bedded ironsands are seen in several 

 places ; they become finer and slightly clayey below, these cha- 

 racters generally increasing downward. The beds of Local Group 4
