8. Wadhurst Line.—This line runs by Wadhurst and Hawks- 
hurst, to the south-west of which place it is lost. It also ranges 
westerly along the ridge between Wadhurst and Mark Cross. 
4. Crowborough Line.—Crowborough Beacon stands on what must ~ 
be regarded as the great central ridge of the district. The anticlinal 
line runs near the Beacon and is continued westerly to the north 
of Balcombe. No traces of it: however are distinguishable beyond 
Horsham. 
5. Cuckfield Line.—This line: extends parallel to that last described, 
and immediately to the north of Cuckfield. It is not to be traced far to 
the west of that place. To the east it iscontinued across the Brighton 
railway, where it was very distinctly exhibited in the new cuttings. 
6. Frant Line-—At Lamberhurst this line is distinctly marked. 
It proceeds westward along Frant Hill, where its evidence, however, 
is not very distinct. It appears to be lost entirely not far to the west . 
of Frant. 
7. Bidborough and Brenchley Line.—Bidborough Hill is onuiea by 
a strong flexure of the beds by which the Hastings sand is brought 
up from beneath the Weald clay. Brenchley Hill is formed in the 
same manner, but presents a more distinct anticlinal arrangement. 
These hills are separated by a wide transverse valley of denudation, 
but there can be little doubt, it is conceived, that they belong to the 
same line of elevation. The dislocation is also continued westward, 
but with less distinctness, across the Medway. 
All these lines preserve a remarkable parallelism with each other 
and with the curved central avis of the district. 
The author also describes several transverse valleys of the central 
portion of the district, and states the evidence on which he believes 
them to have originated in transverse dislocations. 
8. Greenhurst Line.—This line has been described by Mr. Martin, 
by whom it was first detected. It is distinctly marked from a 
point south-west of Pulborough, whence it runs not far from and 
parallel to the chalk escarpment, till it strikes into the chall at 
Piecomb. Its continuation westward is not very distinct, but east- 
ward it is strongly defined at Lewes. Several remarkable transverse 
valleys across the greensand ridge are also found in the south- 
western part of the district, and present evidence of haying originated 
in transverse dislocations. ‘Their directions are as neatly: as possible 
perpendicular to that of the Greenhurst line. 
9. Line from Farnham to Seven Ouks.—This line runs parallel to 
the chalk escarpment of the North Downs and near to it. Itisa 
line of flexure, with a great dip to the north, but without the cor- 
responding dip to the south necessary to form an anticlinal arrange- 
ment, except in one or two localities. Towards the west it runs 
immediately at the foot of the Hog’s Back with a dip, which, near its 
western extremity, amounts to 70 or 80 degrees. Near Guildford 
it passes by the foot of the hill on which Margaret’s chapel stands. 
. To the east it passes south of Dorking and Reigate to the summit of 
Tilburstow Hill. Itis afterwards continued by Limpsfield to the east 
of Seven Oaks, as formerly described by Dr. Fitton. At some points
