exposed inland. This is due to (1) the eastward extension of 

 Weston Woods, for over a mile and a half; and (2) the absence 

 of exposures to the north of the track which runs along the crest of 

 Milton Hill. Nevertheless, conclusive evidence of the easterly 

 extension of the Spring-Cove lava has been obtained by other 

 workers, and, as will be seen, this agrees with my own determina- 

 tion of the stratigraphical features of the Upper Syringothyris- 

 Eeds. 



Fossiliferous limestones, included in the upper 300 feet of the 

 zone, are exposed in a continuous series of quarries and hillside 

 exposures, lying approximately on a line of strike, and extending 

 from the Town Quarry, above Weston, eastward to the slopes 

 under Worle Tower. Proceeding eastward, the exposures of this 

 series are as follows : — - 



(1; The Town Quarry. 



(2) A small quarry about 100 yards east of the Town Quarry. 



(3) Numerous exposures along the north side of Cecil Road. 



(4) A small quarry in the woods, above Eastfield Park. 



(5) A disused quarry on the edge of* the woods, a little west of Ashcombe 



Wood. 



(6) Milton Quarry. 



(7) Four quarries near the road leading from Milton up to Miltonhill ; 



two of these lie on the right of the road, and two on the left. 



(8) A quarry on Milton Hill. This lies on the top of the hill, about 



300 yards along the track leading from Miltonhill to Worle Tower, 

 and just above Ranscombe House. 



(9) A series of hillside exposures and small disused quarries, extending 



from Milton Hill to the slopes south of Worle Tower. 



Along the hill above Weston, the strike of the beds is approxi- 

 mately east and west, but in the neighbourhood of Milton Hill it 

 has shifted to within a few degrees of north-east and south-west. 

 Consequently, as we proceed eastward, higher and higher parts of 

 the series overlap each other against the fault (which runs a little 

 north of east), and the lower beds of the series do not extend far 

 beyond the quarry on Milton Hill. 



In this connection we come to some interesting conclusions with 

 regard to the easterly extension of the Spring-Cove igneous rocks. 

 It is evident that the lava, which occurs low down in the Syringo- 

 thyris-Zone, cannot extend east of Milton Hill ; and this conclusion 

 is fully borne out by the observations of those geologists who have 

 paid special attention to the igneous rocks. 1 



The easternmost exposure of the Syringothyris-~Beds, which 

 shows beds very near the top of the zone, occurs in the lane leading 

 from W T orle Tower to the road. 



The fault can be located near the sharp bend in this lane, about 

 280 yards E. 20° S. of Worle Tower. Upper Syringothyris-Beds 

 lie south-west of this point, while Upper Seminula-Beds appear 

 immediately to the north-east.
