STRATA AT POUNCEFORD. 2^7 
tertiary series, that they could not, by the inspec- 
tion of hand specimens, be distinguished. 
4. Calciferous grit, like that of Tilgate ; with 
bluish grey limestone. Contains abundance of 
Equisetum Lyellii. 
5, Shale and clay. 
(i. Limestone, with cyclades ; like the “Greys” 
of Asburnham. 
The sketch, p. 226., represents a “ horse, or 
fault, near the above section. 
In the strata at Swife’s farm, w^ere collected, ver- 
tebrm and ribs of saurians, and turtles ; teeth of 
crocodile, scales of fishes, and a great number of 
Equiseta Lyellii, sphenopterites, and traces of 
other ferns. Shells of the genera cyclas (the most 
common), psammobia, mytilus, melanopsis, palu- 
dina, &c. 
I shall now proceed to mention some other 
interesting localities of the harder varieties of 
grit, limestone, and ironstone, whose geological 
position is not at present satisfactorily determined ; 
but which appear to belong to the inferior group 
of the Wealden, rather than to the upper strata. 
Pit-wood Quarry near Cross-in-hand This 
quarry lies in a valley to the right of the road 
leading to Burwash, and exhibits the following 
section : — 
1. Soft fawn-coloured sandstone, 22 feet. 
2. Argillaceous beds, with an intermixture of 
sand, and thin laminm of marl or clay. 
3. Compact stone, exceedingly hard, in many 
parts highly ferruginous ; a single layer, two feet 
thick : it is etnployed to repair the roads. This
