OF THE BATH-DOCLT1NG DISTRICT. 



405 



The section in the railway-cutting west of Mells-Road Station is 

 described below, but it is by no means easy to determine the limits 

 of the several subdivisions. Almost the complete sequence for this 

 district is visible. The strata are arranged in a gentle syncline, 

 and the clayey nature of the soil in the middle of the (horizontal) 

 section shows that the Inferior Oolite has only just been removed. 

 Below the Inferior Oolite about 4 feet of Liassic clay is visible ; and, 

 since this clay throws out springs, it will be understood that it is 

 not very sandy. South of this section the Oolite gives rise to a 

 very level tract.

All the quarries between Mells and Radstock are now abandoned. 

 About half a mile east of Lentney Farm, by the side of the Radstock 

 road, are two quarries showing much the same section. In that 

 on the east side, the Doulting Stone and Anabacia-Jjiraestones have 

 been worked somewhat extensively. ' The beds are more pebbly 

 than usual ; the upper surfaces are bored, and have, in many cases, 

 oysters adhering to them. Quartz-pebbles are not infrequent, some 

 measuring as much as an inch in length. The following fossils 

 were collected: — Ostreasip., Lima (Limea) diiplicata, Sow., Trichites, 

 Pecien (Syncyclonema) demissus, Phillips, Trigonia sp. indet., Serpula 

 cf. Umax, Goldf ., Pseudomelania, Berenicea (on a fragment of a shell), 

 Acanthothyris spinosa, Ehynchonella hampenensis, and Anabaeia com- 

 planata. Altogether the beds exposed measure about 25 feet. 



Near some cottages by the side of the road at Huish the Anabacia- 

 Limestones are more typically developed again. 



1 This section lies between the two bridges west of the station.
