contour ; while a short distance south, at Woodhatch, the Ather- 

 rield Clay crops out in two places a little below the 300-foot contour. 

 The levels of the two exposures of the cherts here give these beds 

 a dip to north of 1 in 12 (quite a normal dip) ; and, calculating 

 from that, we must have at least 160 feet of beds below, before 

 reaching the top of the Atherfield Clay. 



Quite apart from their intrinsic resemblance, the position of the 

 Reigate Pebble-beds in the Lower Greensand approximates so 

 closely to that of the Pebble-beds in the west, that there is no 

 doubt in my mind as to their lying on the same horizon. To the 

 south of Reigate Park, in Park Road, at 360 O.D., between 40 and 

 50 feet below the chert-beds in the series, ironsands with scattered 

 small pebbles of the usual kind are seen ; these sands are false- 

 bedded, and have layers of Carstone. These are the beds of Local 

 Group 4, and no doubt lie near the horizon of the section at 

 Trumpetshill. 



The next series of sections claiming attention is upon Redhill 

 Common. At the northern end of the large upper pit there is the 

 following section : — 



Fuller's Earth (with a thick bed of ironstone in it) 4 feet seen. 



Irony clay-beds, with Carstone and pebbles (lydites, quartz, 



etc.) 1 foot 6 in. 



Drab-coloured sands passing into olive-brown sandstone 

 (not calcareous, otherwise resembling Bargate Stone), 



pebbly throughout , 2 feet. 



passing into 



Pebble-bed ; hard loamy sand or soft sandstone, giving a 

 wall-like section with larger pebbles (lydites, quartz, 

 etc.), pebbles of brown clay, and clayey pipings of con- 

 temporaneous origin ; light drab in colour, but some- 

 times stained with iron, the lower 6 inches usually so ; 



with occasional layers hardened into Carstone 2 feet. 



passing into 



Glauconitic sands, coarse and false-bedded and with layers 

 of Carstone, with small pebbles as usual (lydites, quartz, 



etc.) 2 feet seen. 



[Dip N. ; all the beds vary somewhat in composition horizontally.] 



All the beds below the Fuller's Earth may be described as 

 ' Bargate '-like, but are without calcareous matter. Although 

 there is no chert here between the Pebble-beds and the Puller's 

 Earth, it is obvious that these are the same beds as those seen in 

 Pell Street, Reigate. The beds just tabled can be followed south- 

 wards along the pit as sections occur, they run out in succession at 

 the surface, and in the high section at the south end of the pit are 

 seen to be underlain by coarse, false-bedded, buff sands and grits, 

 with the usual pebbles and layers of Carstone (full 30 feet seen). 

 These beds are again underlain by beds of brilliant crimson-mottled 

 sands, which appear to be peculiar to this locality and may have 

 given it its appropriate name. These sands very much suggest a 

 lacustrine origin. 



Immediately south of, and below, the pit just described, there is 

 another pit on the high road to Brighton in which the coarse, false- 

 bedded, buff sands overlying the compacter crimson-mottled sands
