CLENT HILLS BRECCIA.

Permian and Carboniferous Sandstone. I cannot speak with any 
certainty on this point, in connection with Romsley, having been 
there so few times. I always find the largest rocks are Rhyolitic 
ash, and are on the western sides of the hills, the largest being on 
the north-west of Clent and on the west of Walton at Highfield 
Coppice. At Highfield Coppice the whole hillside is covered with 
many blocks of more than ordinary size, and is well worth a visit. 
A comparison of hand specimens of igneous rocks collected at the 
Lickey and at Nuneaton with those collected on these hills shows a 
similarity. I do not venture to state anything more definite than 
this, pending a microscopic examination. If any member would 
like to examine any of the Clent Hill rocks, I should be only 
too glad to supply any number of specimens, and give every 
assistance in my power. # 
So that we can properly consider how these Breccias were 
formed, it is necessary to shortly introduce the Abberley Hill 
Breccia. The Dudley and Midland Geological Society this year 
paid a visit to the large quarry shown in the frontispiece. At this 
meeting a quantity of pieces of fossiliferous rock were found. 
I am unable to give you a list of all the fossils, but they include a 
Patella and Clionetes in pieces of rock belonging to the Upper 
Ludlow passage bed to the Old Red Sandstone. There are also 
quantities of Upper Ludlow Limestone and shale and Old Red 
Sandstone, which are the local rocks. The fossiliferous rocks 
were chiefly in one layer, about 6in. thick, mixed with ash, 
and I followed it for 20ft. to 30ft. There is also a very 
large boulder of ash, 2ft. 6in. by 1ft. 6in. The rocks are 
much more rounded than those on Clent. I could not find 
a single piece of Llandovery. The matrix is very hard, and the 
Breccia is stratified. Many of the stratified rocks show on the 
partially decomposed surface very deep indentations, which 
correspond exactly with the projections on the surrounding stones. 
These facts show a great dissimilarity from Clent, and that the 
*Mr. W. J. Harrison, jun., has very kindly undertaken to examine the 
igneous rocks, and it is hoped at some future time to give the result.
