anticlinal line quite up to that place, to the north of which a distinct system of 

 lines commences. 



Brightling and Battle Lines. — Brightling Down is one of the highest points in 

 this part of the country, its height being stated to be 646 feet. The anticlinal line 

 passes through its summit, where it is extremely well defined, the dip both on the 

 north and south being A^ery considerable. It extends westward through the northern 

 extremity of Heathfield Park, beyond which I could detect no distinct evidence 

 of its continuation. To the eastward it does not appear to be distinctly continued 

 beyond the village of Brightling, which is situated on the extremity of that part of 

 the range of hill. Immediately on the south of Brightling Hill is another on which 

 Dallington is situated, and which is continued more or less distinctly to Battle. 

 This line however is not anticlinal immediately to the south of Brightling Down, 

 nor is the Brightling line transferred to it, where this subordinate range passes 

 farther east than the Brighthng one ; for I distinctly ascertained the general dip 

 to be to the south, on the north side of the Dallington range, about Darvel Beach 

 and in Limekiln Wood. 



Further to the east, we obtain an instructive section along the new road from 

 Battle to St. John's Cross, which runs nearly in a straight hne between those places. 

 Immediately to the north of Battle, the hill on which the windmills stand is shown 

 by the new cuttings to be strongly anticlinal. The direction of the anticlinal line 

 appeared to coincide with that of the hill, and to be two points to the south of east 

 (E.S.E.). It is not continued far to the east, nor to the west. 1 conceive it to 

 be independent both of the Hastings and Brightling lines. Proceeding northward 

 towards St. John's Cross, we recognize a synclinal line in crossing the valley and 

 small stream about a mile and a half from Battle ; and another at a point of the 

 road east of Mountfield. The exact position of the anticlinal between them is not 

 very distinctly marked, but must be very nearly as indicated on the map. North 

 of the last-mentioned synchnal line the beds rise rapidly up to St. John's Cross, 

 on the north of which they appear to descend very gradually to the river at 

 Robertsbridge, thus forming a third anticlinal line between Battle and that 

 place. Of the two northernmost I had no means of determining the exact direc- 

 tions. 



On the west of the new road above mentioned, the dip is said to be very irre- 

 gular, and the country much dislocated. The irregularity is probably more appa- 

 rent than real, as far as regards the positions of the lines of elevation. There is 

 scarcely any irregularity in the dip along the new road, which affords an almost 

 continuous section from Battle to St. John's Cross, though the existence of 

 great irregularity might have been inferred from merely insulated observations 

 along that section. Still we might reasonably expect some irregularity about the
