Murckisoris Silurian System. 31 



western parts of Worcestershire the New Red System begins 

 to expand ; and conglomerates, such as those described, 

 are partially underlaid by soft red sandstone, both on the 

 eastern flanks of Walsgrave hill, near the Hundred House, 

 and at the termination of the Abberley Ridge. Thence 

 to the north, the boundary line of the New Red Sandstone 

 comes in contact with the stiff clays and flagstones of 

 the Old Red, but within two miles of Bewdley it begins 

 to flank the coal measures ; and other examples of the an- 

 gular, coarse, and trappean conglomerate, or breccia, occur, 

 the fragments of trap having been derived, it is presumed, 

 from Stugbury hill. A similar rock is found at Wars Hill, 

 on the left bank of the Severn, also rising up on the 

 edge of the lower New Red, where it is bounded by the 

 Old Red Sandstone, the conglomerate being interposed 

 between the intrusive rock and the soft sandstone of Kid- 

 derminster! The same conglomerate, subordinate to, and 

 winding through masses of thick bedded sandstone, are 

 instructively displayed at Winterdine, near Bewdley, and 

 contain fragments of coal measure, grits, and concretionary 

 trap, both of which rocks being in site adjacent to the con- 

 glomerate, are of angular forms, whilst the quartz and peb- 

 bles of older rocks, which have been transported from 

 greater distance, are rounded. These strata are uncon- 

 formable to the adjoining sandstone and grits of the coal 

 measures, and pass beneath the Red Sandstone which forms 

 the cliffs on the left bank of the Severn, and ranges to the 

 town of Kidderminster. 



" We may therefore proceed to the consideration of the 

 structure of these tracts where natural sections exposing a 

 full development of the lower members of the system, exhibit, 

 besides the calcareous and other conglomerates before describ- 

 ed, the Lower New Red Sandstone as a great and distinct 

 subjacent formation of sandstone, marl, and shale, with subor- 

 dinate courses of impure concretionary limestone, the whole 

 passing down gradually into the carboniferous system."
