FDLLONIAN : BRIDPORT. 235 
are not continuous, so that while we have positive evidence of 
clayey beds above the Inferior Oolite and beneath the Forest 
Marble, we have no section to show the entire sequence. It is not 
right under these circumstances to deny the persistence of the 
Fuller's Earth Rock, although it is just possible it may have 
tapered away or have been overlapped by the Forest Marble. 
For some distance inland we find no distinct bed of Fuller's 
Earth Rock, for it has not been traced on the Geological Survey 
Map beyond a tract of ground between South Perrot and 
Mosterton : thence over the greater part of the country to the 
south and south-east, towards Bridport, the Cretaceous rocks 
overlap the Forest Marble and rest directly on the Fullonian Bed^. 
The "Fuller's Earth clay" was opened up in the railway- 
cutting near Smokeham, south of Powerstock station, and a 
number of fossils (now in the Dorchester Museum), were obtained 
from the beds : but the cutting is obscured. By Wicker Farm, 
nearer to Toller Porcorum, the beds have been exposed in the 
railway-cutting : here they consist of bluish-grey slightly calcareous 
clay, and this is burnt (with " slack " or small coal) for ballast, 
that is used on the railway. At an adjoining kiln, the clay is 
used for the manufacture of bricks and drain-pipes. The following 
fossils were collected by Mr. J. Rhodes and myself at this 
locality : 
Tooth of Saurian. 
Ammonites. 
Belemnites parallelus. 
Avicula costata. 
Miinsteri. 
Cardium ? 
Lima. 
Modiola Lonsdalei. 
Nucula variabilis. 
Ostrea acumitiata. 
Sowerbyi ? 
Posidonomya. 
Serpula tetragona. 
Rhynchonella varians. 
Waldheimia ornithocephala. 
These beds most probably belong to the Lower Fuller's Earth 
clay, as the same group of fossils occurs in the L,wer beds that 
are exposed above the Inferior Oolite in the railway-cutting 
west of Crewkerne station. At that locality Avicula cchinata and 
fragments of Pecten occur, in addition to a number of the species 
above noted. Sections are to be seen here and there in the 
brickyard west of Crewkerne station, and in that at High Cross 
Hill, between Haselbury and East Chinnock. Here we have 
grey clay with a good many nodules of "race," due probably to 
the decay of fossils ; but Belemnites are preserved. (See Fig. 35, 
p. 69.) ' 
Sherborne to East Cranmore. 
Passing eastwards from Crewkerne, we come to the best 
development of the Fullonian series in this country. From 
Thorntbrd near Sherborne to the neighbourhood of Bruton, the 
Lower and Upper Fuller's Earth clays are separated by a mass 
of Fuller's Earth Kock, which forms a well-marked escarpment. 
The Lower Fuller's Earth clay with an occasional band of 
earthy limestone, may be seen resting on the Inferior Oolite, and 
faulted against it, in the railway-cutting east of Bradford Abbas.
