county of Sussex. The iron-sand only just appears at the south- 

 eastern corner of this division. 



The eastern portion of this division lies in the valley of the Med- 

 way, and is drained by a considerable branch of that river, which rises 

 in the parishes of Godstone and Home, and, passing through the parish 

 of Lingfield, quits Surrey, and enters Kent. The remainder of the 

 division is drained by the various tributaries to the Mole, which river 

 falls into the Thames. 



4. Northern Division. 



The northern division has the river Thames, from Kingston to Wey- 

 bridge, for its northern boundary, and thence for its western the canal 

 to Newark Mill ; the south, by Ockham Common to Cobham Court, 

 and the river Mole to Leatherhead. The turnpike-road thence through 

 Epsom and Ewell to Kingston constitutes the eastern boundary; the 

 ai'ea occupying about sixty-one square miles. 



The principal feature of this district is the London clay, portions of 

 which are covered with the Bagshot sand, as in the vicinity of King- 

 ston, Esher, and the western side, where it attains considerable eleva- 

 tion, as at St. George's Hill. 



This division is drained by the rivers Wey and Mole. 



5. Central Division. 



The central division has a portion of its northern boundary defined 

 by the turnpike-road from Epsom to Leatherhead, and the remainder 

 by the river Mole, thence to Cobham Court, and continued onwards 

 by Newark Abbey to the river Wey, the latter constituting the western 

 boundary to its junction with the Reading and Reigate Railway at 

 Shalford, whence the Railway to Reigate forms the southern, and the 

 turnpike-road thence to Epsom the western, boundaries. The area 

 is about eighty-seven square miles. 



This division is principally occupied by the chalk, which constitutes 

 the entire breadth of its eastern boundary, and gradually narrows 

 towards Guildford. The surface, where not altered by cultivation, is 

 covered with a short, verdant turf. The whole range presents to the 

 south a bold escarpment, from which some magnificent views are ob- 

 tained over the weald. That portion of the greensand which runs 

 along the southern boundary rises in considerable elevations ; and at 

 St. Martha's the sand rises with such rapidity, that it equals or out- 

 tops the chalk. The north-west portion of this division is covered 

 with the London clay.
