There are many sections of Upper Silurian rocks 
exposed near to the Corve Dale road; yet, as I have 
examined them but slightly, I cannot say what may be 
found there. I have no doubt but that they contain 
their usual fossil remains. 
The turnpike road from Siefton, for some miles north¬ 
ward, runs nearly in the junction of the Old Red and 
Upper Ludlow ; and I should think that a diligent 
search would probably find the Tin Mill shale and the 
Ludlow bone bed exposed in several places. Near 
Tugford and Abdon are several bands of cornstone, 
which are quarried in many places ; and on the Brown 
Clee Hill are several old coal mines, not now worked. 
All this district has received but little attention from 
geologists.

All along the summit of Norton’s Camp is a very a 
grand section of Aymestry limestone ; it is in general 1 
very unfossiliferous; the best locality is a little distance 5 
above Onibury Cottage, where it has been very exten- ( 
sively quarried. 
A very interesting geological trip is up the side of 11 
the Onny river, commencing at Strefford’s Bridge, which ; 
is about one mile from Craven Arms station. A short J 
distance above the bridge, in the bed of the river, the 1 
Wenlock shale is exposed; and when the water is low, 
some very good specimens of Phacops longicaudatus can 81 
be procured. In the field immediately above the Cheney 01 
Longville foot-bridge, is the celebrated Onny section. - 
a most interesting one, as the junction of the Upper 
and Lower Silurian occurs here; the bottom beds of ' J 
the Wenlock (called the Purple Shale), the Pentamerus •
