26 IRON SAND FORMATION. 



2. Grey sand about 6 or 8 inches thick, containing minute 



fragments of charred wood. 



3. Sandy marl two feet thick. 



4. Sand and sandstone highly ferruginous. 



5. White sand and sandstone. 



On the southern slope of Horsted hill the sand is covered by a bed 

 of peat, six feet tliick, which extends over several fields, and is cut for 

 domestic purposes. 



The wells in the neighbourhood are about sixty feet deep, and have 

 a constant supply of good water. 



Proceeding northward, the sandstone presents a bolder outline, and 

 rocks of considerable magnitude protrude through the soil on both sides 

 of the road. The strata are from three to six feet thick, and are separated 

 from each other, by thin layers of soft sandstone shale ; their incHnation 

 is towards the south-west except in a few instances, where a contrary 

 direction is observable. 



In the immediate vicinity of Uckfield, grey sandstone rocks of low 

 elevation are very numerous. Their summits are rounded and covered 

 for the most part with coppices and underwood; but their sides are bare, 

 and exhibit evident traces of diluvian action. 



Near " The Kocks," the seat of Mrs. Jackson, about half a mile west 

 of Uckfield, a group of sandstone rocks occurs, under circumstances of 

 considerable beauty and picturesque effect. The path that leads to this 

 interesting spot lies to the right of the road, and, by a circuitous route, 

 conducts the spectator to the centre of a wood, when a beautiful lake, 

 nearly surrounded by rocks, suddenly opens to the view. The cliffs, over- 

 hanging the water, are from twenty to thirty feet high, and are sur- 

 mounted by forest trees and underwood. In some places the rocks are 

 nearly perpendicular; in others they descend with a gentle slope to the 

 water's edge, the declivity being covered by a luxuriant vegetation. On 

 the northern margin, a projecting point of high rock is perforated by a 

 natural archway, that has been enlarged by art, and this leads to a recess 

 in the sandstone on a level with the bosom of the lake. From this point
