538 A. CHAMPERNOWNE AND W. A. E. USSHER ON THE 
slaty beds intercalated, dip E. at from 5° to 20°, and at Tivington 
N.E. at 30°. 
The valley between Grabbist Hill and Luckham is occupied by 
red sands, breccias, and marls of the Triassi¢ series, in part con- 
cealed by alluvia. The relations of the Triassic beds in an area in 
which they may be expected to present much local lithological 
variation, and where they would naturally attenuate, notwithstand- 
ing very high dips, throw hardly any light upon the disturbances 
affecting the older rocks; but a much more careful study of the 
latter than we were able to make would no doubt clear up much 
that is ambiguous in the relations of the Trias, and show whether 
beds of Pre-Keuper age had been deposited in the area to the west 
of Williton, as lithological similarities seem to suggest. 
From Luckham to Stoke Pero the surface is strewn with frag- 
ments of grit. At about half a mile east from Cloutsham coarse red 
and lilac quartzose grits are exposed, dipping E. 25° S. at 10°. 
In the stream between Cloutsham and Bagley siliceous grits dip 
eastward at 20°. Near Cloutsham and Brackslade no dips are ob- 
tainable; red and brown grit-stones are scattered over the surface. 
Near Stoke Pero a south-easterly dip of 23° was obtained in red 
and brown grits. The grits in this neighbourhood approach rather 
to the Hangman than the Foreland type; so that the sharp bend in 
the stream to the north of Cloutsham may be due to a dislocation 
bringing up Foreland beds to the north. 
By the road from Stoke Pero towards Bendles Barrows siliceous 
grit-stones of the Hangman type are strewn over the surface. 
On ascending the opposite slope of the valley to the west of Stoke 
Pero a thick head of brown grit-stones conceals the rock. At the 
head of a stream-gorge, at about half a mile south of Wilmotsham, 
buff slaty grit gives a surface-dip 8. 30° EK. at about 15°. By the 
road southward from Pool, where the bend is shown on the map (to 
the N.E. of Bendles Barrows), a section 5 feet deep exposes greenish 
slaty grits or thick slates, apparently vertical and striking N.E., 
terminally curved. 
Westward of Bendles Barrows, in and by the road over Lucott 
Hill, at a few chains south of the stream, grey slaty beds are inter- 
calated in red and coarse brown grits, dipping 8.W. at from 20° to 
40°. As their strike coincides in direction with that of the greenish 
slates on the other side of Bendles Barrows before mentioned, we 
have here the evidence of intercalation of slaty materials with grits 
of the Hangman series which is so well shown in the cliff-face of 
the Little Hangman Hill, on the North-Devon coast. 
On the southern slope of Lucott Hill a northerly surface-dip was 
obtained in slaty grits; at the road-junction on the hill greenish 
and red grits and slaty beds seem to dip 8. 10° W. 
From Lucott Hill (fig. 3) we struck into the East-Lynn valley at a 
point due west of the bottom of the word “Zucott” on the map, where 
we observed hard thick-bedded greyish siliceous grits of the Hangman 
series dipping southward at from 20° to 25°. Proceeding down the 
valley, at about ten chains from the above, a south-easterly dip of
