Langport Beds. Sun-Bed. 



Bed 14 is the ' Blue Clog '—No. 14 of the Windmill-Hill section 

 at Butleigh (p. 38). Thence upwards to Bed 31 the sequence is 

 the same as that which is exposed at Windmill Hill, with the 

 differences in thickness noted in square brackets in the Windmill- 

 Hill record. 



In the Cary-B ridge cutting these Lower Liassic beds are affected 

 by a slight overthrust-fault, and are placed in juxtaposition with the 

 Cotham and Langport Beds. Here the Cotham Marble (4 inches) 

 was discovered in situ, and it exhibited that incipiently-conglomeratic 

 facies which has earned for it the name of ' false Cotham '} 



(B) The Sparkford Hill Area. 



(i) Introduction. — North of Queen's Camel, near Sparkford, is 

 a stretch of elevated ground bearing the names of Sparkford Hill 

 and Camel Hill. Prom the general geology it is obvious that this 

 inlier owes its genesis to anticlinal folding and subsequent faulting : 

 the anticline being doubtless a continuation of that to which 

 I referred when dealing with Blue Anchor Point and the Polden 

 Hills. 



The inlier is cut through by the Great Western Railway, and 

 when the line was made a very fine section was exposed. 



(ii) Stratigraphical Details. 



Sparkford Hill railway-cutting. — This fine section is 

 now, however, mostly overgrown ; fortunately, it was described in 



1 For the guidance of future observers, it may be as well to state that, when 

 the banks of the deep cuttings on this line had been smoothed down, rerl sandy 

 material was frequently spread over the sides. From a distance, this led one 

 to think that the cutting was wholly in the red marls, instead of in a variety 

 of deposits (Rhsetic or Liassic, or both).
