MENDIP NOTES. 179 



Concerning this locality, I will only transcribe the note I 

 made on the spot. " In an orchard np on side of hill, much 

 overgrown with bracken and some furze, many fragments of 

 red sandstone or quartzite. Many of them very hard like 

 Millstone Grit ; some of them with rusty spots like the Mill- 

 stone Grit near the dilapidated buildings West of the lane 

 from Easton to Priddy, near the Ebbor Valley, some softer 

 and more like Old Red Sandstone. In a field below, cattle 

 pond, sides of which have very hard Red Sandstone like Mill- 

 stone Grit. On the whole I am inclined to regard this as 

 Millstone Grit not Old Red Sandstone. The relation to other 

 rocks not clear."

I have been desirous of obtaining satisfactory data for 

 estimating the thickness of the various subdivisions of the 

 Lower Carboniferous series of deposits in the Mendip area, 

 and have collected a considerable body of observations. 



It has been mentioned above that there seems some doubt 

 whether the Upper Transition Beds (Upper Limestone 

 Shales) of the Avon Section are represented as such in the 

 Mendip area. 



The Lower Transition Beds are, however, well represented, 

 and contain the equivalent of the Biyozoa Bed of the Clifton 

 Avon Section. They may be measured with fair accuracy 

 at Burrington Combe, where it is al^o possible to estimate 

 the thickness of the Lower or Encrinital Limestone, and the 

 equivalent of the Gully Oolite of the Clifton Section. It 

 may be possible also to estimate the thickness of the Lower 

 Transition Beds in the railway cutting between Binegar and 

 Maesbury, near the latter station (misspelt Masbury by the 

 G.W.R.). The lower limit is there, however, obscured, and 

 I have not, as yet, calculated out the thickness.
