8 GEOLOGICAL STRUCTURE 



great Wealden denudation as the Malm Rock or 

 the Chalk above it. Everywhere, in short, whether 

 in the parish of Harting, or in that of Buriton on the 

 west, and of Elstead on the east, it yields grass and 

 trees only, and is scarcely ever turned into arable 

 land. In short, the outline of the Gault is everywhere 

 marked as enclosed between the grey Malm Rock 

 above it and the yellow and white sands on which it 

 lies. Fine specimens of the meadows on this formation 

 are those of Down Park ; and it is by this same clay 

 that the adjacent large ponds, the property of Lady 

 Fetherstonhaugh, are held up. The woodlands called 

 the Severalls are also on it. Houses are rarely built 

 on the Gault ; and if people value good health, and 

 eschew rheumatism, they would never live on this re- 

 tentive clay, which is only suitable for fattening bullocks 

 and raising oaks. 



Though rare in this parish, fossils occur in great 

 abundance elsewhere in the Gault, and notably at 

 Folkestone, where the Ammonites dentatus, which I 

 have found in West Sussex, is associated with Plicatula 

 pectenoides, Inoceramus concentricus, I. sulcatus, Cu- 

 cullaea fibrosa, Nucula pectinata, Dentalium decus- 

 satum, Rostellaria carinata, Natica Gaultina, Ammo- 

 nites splendens, A. tuberculatus, A. interruptus, and 

 Hamites intermedius. 



The junction of the Gault with the upper beds of 

 the Lower Greensand is admirably exposed at the 

 Kilns to the right of the road that runs between 

 Down Park and the Ryefield Farm, where the contact 

 of clay and sand has led to the manufacture of bricks. 

 There the sands, both ferruginous and pure white, 

 rise up from beneath the Gault to form the beautiful 

 low hills called West Heath, the most northern 

 portion of the Up Park estate, and distant from the 

 mansion upwards of three miles. A very instructive 

 section of these sands is exhibited on the side of the 

 road as you advance to the valley of the Rother;
