CLENT HILLS BRECCIA.* 
BY W. WICKHAM KING. 
Much lias been written about the Breccias bounding the Mid¬ 
land Coal Fields, but your attention is directed this evening to the 
Clent Hills Breccia. It covers Wyclibury Hill about 750ft., Clent 
Hill 997ft., Walton Hill 1,036ft., and Bomsley Hill 930ft., which 
go to form the hills known collectively as the Clent Hills. Having 
the advantage of living at the foot of Wyclibury. some three years 
since, I thought I could not do better than try to throw some 
light on the difficult problem of what rocks these measures com¬ 
prised, and thereby endeavour to ascertain by what agency they 
were here deposited. Some new facts have been ascertained which 
it is a pleasure to have an opportunity of communicating to you, 
but much more wants to be done. I hope some members will be 
sufficiently interested to do some field work themselves on these 
hills. 
The only papers which deal directly with these hills are Pro¬ 
fessor Ramsay’s paper in the “Geological Quarterly Journal,” Vol. 
II., p. 185; Dr. Buckland’s paper, “Geological Journal,” Vol. XI.. 
p. 130; Hull’s “Triassic and Permian Rocks,” and Beete Jukes’ 
“ South Staffordshire Coal Field.” 
The Breccia is truly sedimentary and stratified, as seen by the 
photograph of section behind a house at Adam’s Hill, Clent, where 
the dip is west.f Within a few hundred yards west of this point 
the Breccias are overlaid by the Bunter pebble bed, which lies 
along the western side of Clent Hill and the west and south 
sides of Walton Hill. It is composed nearly entirely of an aggre¬ 
gation of angular and subangular fragments of several different 
kinds of rocks, which go to form a great thickness of detritus, and 
the whole mass and many of the fragments are throughout very
