or so-called Lower Silurian system of Shelve and Meadowtovvn. The great double 

 fault bounding the Caradoc range can be followed by the eye far to the north-east 

 and south-west of Caradoc itself, for between its jaws lie all the main hills of 

 the country, Wartle, Knowle, Ragleth, Caradoc, the Lawley, the Wrekin, and 

 many others. Looking eastwards from the Caradoc, towards the Clee Hills, we 

 'have a much simpler structure of country. The Ordovician, the Silurian, the 

 Old Red Sandstone, the Coal formation repose one over the other, bed over bed, 

 turning the weather worn edges of their component sheets, like the steps of a 

 giant stairway, towards the observer on the Caradoc itself. The bottom 

 bed of the Ordovician of the Caradoc, or the so-called Caradoc formation, 

 is the Hoar Edge Grit which forms the great mass of the Hoar Edge itself. 

 As we come southwards towards the Caradoc it is cut off by the great faults 

 in the valley. On the Hoar Edge Grit rests the group of beds which are 

 known as the Harnage Shales, which form most of the deep valley between 

 the Hoar Edge and the Enchmarsh scarp, and slope down the valley to the 

 farmhouse of the Cwm. The Enchmarsh and Chatwall ridge is formed of the 

 Chatwall or Horderley Sandstone, and can be followed by the eye continuously 

 from Enchmarsh to Cardington Heights and the Battle Stone. On the Chatwall 

 Sandstone rest the Longville Flags, which fill up all the country east to Cardington 

 village. Beyond the village we find the Trinucleus Shales, coming out from under 

 the Llandovery beds which lie at the base of the Wenlook Shale, and constitute 

 the lowest formation of the overlying Silurian System.
