342 LOWER OOLITIC ROCKS OF ENGLAND : 
purposes and road-metal, and occasionally for lime-burning 
(shown to a depth of 10 feet, but probably nearly 20 feet thick). 
At the base there is a considerable thickness of clays and lime- 
stone-shales with thin bands of shell-limestone, resting on the 
Rhi/nchoncUa-bed. With the exception of Ostrca and Rhyn- 
chonella, fossils are abundant only in this basement-bed. The 
stone-beds are well shown in a scarp that extends above West 
Bexington towards Swyre, and there are quarries at Cogdon, 
Bredy, North Hill, and Bothenhampton. 
At Bothenhampton the shelly limestones have been largely 
worked for a long period, and the hill-side to the south of the 
village is scarred with old pits. Here the stone has been pro- 
cured, along the dip-slope : for the beds are inclined northwards 
towards the village, where they are faulted against the Middle 
Lias. This fault is a continuation of that seen in the cliff east of 
Eype mouth, where the downthrow must be at least 425 feet. 
(See Fig. 41, p. 52, of the Memoir on the Lias.) 
The quarries at Bothenhampton afford some of the best sections 
of the Forest Marble in this country. The sections show the 
following beds : 
FT. IN. 
f Brown clay aud soil - - 5 to 6 
Bluish-grey iron-stained and marly 
clays, with " race," lamince of sandy 
limestone, and thin flags of blue 
shelly limestone - - - 14 
Bluish-grey oolitic shell-limestone ; 
false-bedded and with ochreous 
Mar-Li 
" 
nodules, lignite, and impersistent 
clay-seams. Fossils with purplish 
tinges, including Oyprina loweana, 
Lima duplicata, L. cardiiformis, 
Pecten annulaius, P. lens, P. vagans, 
Ostrea Sowerbyi, and fragments of 
Apiocrimis ParJcinso7ii - 6 
Alternations of blue marly clay and 
shell-limestone, with lignite - 5 
The clays above the mass of limestones are somewhat disturbed 
in places, owing to their slipping along the dip-slope. 
The junction with the basement beds of the Cornbrash was to 
be seen in a lane-cutting south of Bothenhampton church, where 
grey earthy limestones and marls with Avicula echinata, &c., rest 
on a thin series of flaggy shell-limestones and clays that form the 
upper part of the Forest Marble. 
The Forest Marble is well shown in the West Cliff* between 
Bridport Harbour and Eype mouth, overlying the Fullonian for- 
mation or Fuller's Earth, ami occupying a basin-shaped depression 
in that deposit. The junction with the Fuller's Earth is here 
marked by a band of hard fissile white marl, 2 ft. 6 in. to 3 feet 
in thickness, which forms a prominent band in the cliff. Above 
come 8 to 10 feet of bluish-yellow marl, with a layer of hard 
fissile white marl in places : these beds may be included with the 
Fuller's Earth. The next bed is n hard sandy marl, stained
