On a Rhetie Section at Luckington, and Additional Notes on the 
Vobster Quarry. By Rey. H. H. Winwoop, M.A., F.G.S. 
(Read 12th February, 1890.) 
During the past autumn it has been my custom to make a 
weekly expedition, with a geological friend, Professor Lloyd 
Morgan, to examine some of the interesting problems, still 
awaiting solution, afforded by our beautiful neighbourhood. 
On one of the fine days, which at that time of the year 
especially make out-door life so enjoyable, our object was to 
re-visit the Vobster district, and to see whether recent quarrying 
or other works had in any way thrown additional light on those 
complicated disturbances which have employed the pen and 
taxed the imagination of so many geologists to explain. We 
were fortunate in being accompanied on this particular day by 
Mr. McMutrtrie, whose researches in the Radstock Coal Field are 
so well known, and the results of which have been so admirably 
given in various papers contributed by him to our ‘‘ Proceedings.” 
After detraining at Mells Station, we followed the tramway to 
Upper Vobster quarry, and found that Mr. Batey, the proprietor 
of those fine workable beds of Limestone, had done much of late 
to clear up several points, hitherto obscure (but of this more 
anon). Leaving this quarry for the time, we passed the Newbury 
and Mackintosh pits, and whilst looking about for any exposures of 
Limestone, or other rocks in the adjoining fields, dropped into 
“Black Lane” (situated on the line of fault running N. and 
§., and joining the great overlap fault nearer Radstock), and 
followed it up to the well-known section of Limestone lying to 
the East of Luckington Farm. These two quarries—Upper 
Vobster and Luckington—have been rendered classical by past 
descriptions. When seen at a little distance off, the section 
“there exposed appears to be Carboniferous Limestone, with black 
shales resting on its exposed surface. These latter, froma cursory
