PALMOZOIC DISTRICTS OF WEST SOMERSET, 633 
From Dutvrrron Sration to Dunster (fig. 1). 
Dulverton Station is situated upon the junction between the 
Culm-measures and Pilton slates. Towards Brushford, Pilton fossils 
were obtained in nearly vertical slates, passing insensibly into the 
Culm-measures in the railway-cuttings. The well-marked feature 
of Hulverton Hill (to the south of the railway) is formed by the 
- characteristic Culm-measure rocks, which, along a line nearly east 
and west from Coddon Hill (south of Barnstaple) form here and 
there bold hog-backed or conical hills, notably at Swimbridge. 
These beds are easily distinguishable by their baked appearance, 
whitish, buff, or dark-grey colour, and frequent chertoid texture ; 
they consist of thick shales or thin fine-grained grits in tabular 
layers, so intersected by even joints as to afford a valuable road- 
metal without further fracture. In a quarry on Hulverton Hill the 
Coddon beds dip 8. 10 E. at 80°. To the north of the railway, 
to the east of Brushford, grey Pilton slates, vertical, and striking as 
at Hulverton Hill, are exposed in a quarry, from which Prof. Phillips 
obtained many of his best specimens. 
By the highroad to Dulverton, at a mile from the station, bluish- 
grey slates, with thin even beds of limestone and grit, containing 
quartz, dip 8. at from 45° to 65°. In Pixton Park a southerly dip of 
45° was obtained near the gatehouse, where the grey slates strike 
parallel with the Culm rocks of Hulverton Hill. A little north- 
ward of Combe Farm, so far as meagre surface evidence may be re- 
lied upon, a band of buff or brownish grits, either belonging to the 
Cucullea-zone or occurring above it in the Pilton beds, crosses the 
highroad, forming the crest of an anticline; for towards Dulverton 
the Pilton beds dip N. at 75°, and near the bridge across the Barle 
N. 30° W. at 20°. 
Just above Dulverton church the grey slates suddenly give place 
to lilac-red slates and grits, so characteristic of the upper part of 
the Pickwell Down division, which is further evidenced by features 
and surface indications as far north as Court Down. ‘This junction 
is evidently a fault, both from dissimilarity in amount and direction 
exhibited by the dips on either side of it, and from the absence of 
the Cucullwa-grits and olive slates (forming together the Baggy 
Beds, or Lower part of the Pilton series). Proceeding eastward to 
Hele Bridge, further evidence of the fault is furnished by a deve- 
loped continuation of the grit band before noticed near Combe Farm. 
The beds are exposed in Pixton Park, near a gate-house, and dip 
N.W. at 55°. Immediately on the north of the highroad they end 
off sharply against the Pickwell Down division. From Hele Bridge 
northward to Barlynch Abbey, where it is exposed in quarries, 
the Pickwell* series is amply evidenced by characteristic surface- 
stones, vegetation, and form of ground. ‘To the north of the Abbey 
a quarry about 25 feet in height exposes light grey or greenish and 
faint reddish grits with red markings in places, dipping 8. 15° E., 
with undulations, at an average angle of 45°. A cleavage structure
