IV. — On a Section op Midble and Upper Lias Rocks near 

 Evercreech, Somerset. 

 By L. EicHARDSON, F.G.S. 



DURING a brief survey of the Inferior Oolite in the neiglibour- 

 liood of Doulting, Somerset, in 1905, 1 visited a disused quarry 

 on the hill a mile and a half north of Evercreech, and situated where 

 the boundary-line between the Inferior Oolite and Midford Sands is 

 shown on the Geological Survey Map, Sheet xix. I was surprised to 

 find that instead of the somewhat massive rock exposed in the quarry 

 being Inferior Oolite, it was Marlstone, capped with Upper Lias 

 clays and limestones. Since the section is becoming rapidly over- 

 grown, it appears desirable to record the details obtained for the 

 benefit of those who will survey the district in the future for the 

 New Series Maps.
