53. THE HOG'S BACK. 



This remarkable formation consists of a narrow chalk ridge, seven or 

 eight miles in length, running from the break in the chain at Guildford 

 due west towards Farnham. The plateau above does not exceed a few 

 hundred feet in width ; the slopes on either side are cultivated, with 

 occasionally intervening patches of down on the left flank. The Farnham 

 road traversed the ridge from end to end, but the ascent from Guildford 

 being extremely steep, it has been disused, and a new one constructed 

 which ascends the northern flank by an easy gradient, and merges into the 

 old route a mile or two further on. North of the Hog's Back are the sandy 

 heaths and ridges about Pirbright and Bagshot ; south of it are those of 

 the Weald, similar in character, however differing from a geological point 

 of view. The main ridge on this side, at an average distance from the 

 downs of six or seven miles, attains at Hind Head Common an altitude of 

 one thousand feet. Near Puttenham, on one side of the Hog's Back, is an 

 extensive chalk-pit ; on the other, Wanborough Wood. An isolated 

 conical hill, called Crookesbury Hill, distant one mile from the western 

 extremity, and to the south of it, is a prominent object in the landscape. 

 The flora is that of the chalk district, generally ; the drainage, to the 

 Wey.
