Wealden District and the Bas Boulonnais. 7 



section formed by the cliff" exhibits the beds of Hastings sand dipping apparently 

 towards the west, their real mean dip being about two points west of south. This 

 dip is continued to St. Leonards, where it takes the opposite direction. In a newly- 

 cut road in the direction of greatest dip, about a mile west of that place, the incli- 

 nation of the beds was far more distinctly exhibited than in the face of the cliff", 

 the direction of which is not far from that of the strike. This reverse dip is 

 distinctly continued to a point south-east of Bexhill, where the south-westerly dip 

 is again resumed, and a little farther to the west the beds are brought for a short 

 space into nearly a vertical position. The disturbance has produced a fault, the 

 magnitude of which is too great to be determined by the section of the cliff", which 

 does not exceed 20 or oO feet in height. At some distance beyond the fault, the 

 gentle dip of the beds (in a direction about S.S.W.) is again resumed. I did not 

 extend the examination further. 



A range of low hill is represented on the Ordnance Map, running from Bexhill 

 to Ninfield. It was difficult to detect distinct evidence of structure along this 

 ridge ; but I obtained what I considered to be a satisfactory observation, which 

 gave the north-easterly dip about a mile and a half north-west of Bexhill. I was 

 thus led to conclude that the line of elevation, which doubtless accompanies this 

 range for at least two or three miles from the sea, passes along its southern 

 side after passing to the north of Bexhill. I could detect no trace of it near 

 Ninfield. 



Hurstmonceaux Line. — A low range of hill similar to that last mentioned, and in 

 a direction parallel to it. passes to the north of Hurstmonceaux Park. The part 

 called Windmill Hill is distinctly anticlinal. There can be no doubt that a line of 

 elevation coincides with the general direction of the hill. 



Transverse Fractures of the Hastings Line. — About half-way between Battle and 

 Hastings the new road has been cut through High Beach Hill, and exhibits a tine 

 section of a great disturbance, produced by a transverse fracture which has given 

 a local anticlinal arrangement to the beds, and formed a short transverse anticlinal 

 line. The hill and transverse valley on the north of it, by the top of which the 

 road passes, have evidently originated in this cross dislocation. 



The new road above mentioned runs, nearly in a direct line, from High Beach 

 Hill to Hastings, and aff"ords the evidence of another transverse fracture along the 

 valley immediately on the west of Silver Hill. There appears to be an enormous 

 fault, as indicated by the two portions of what is I think unquestionably the same 



tion. The existence of such variations is not more certain than that the general dip is somewhat to the 

 east of north, as stated by Dr. Mantell himself to be the case, at the place just mentioned. The structure 

 of the Brightling ridge is in fact remarkably distinct.
