DESCRIPTION OF THE SECTIONS.

to the productive coal-field, through a large development of Millstone Grit. To the north-east 

 the section passes, first across the trap and broken coal-measures of Kinlet, and thence through 

 a poor coal-field, which as it approaches the banks of the Severn, sinks conformably beneath 

 the Lower New Red Sandstone of Chelmarsh, Higley, Alveley, &c. See pp. 60, 113, 117, 

 121, J31. 



Fig. 2. Section atBewdley, to show the unconformable relations of New Red Sandstone to the car- 

 boniferous grits of the Forest of Wyre. See pp. 54, 134. 



Fig. 3. From the hills north of Shatterford to Kidderminster, showing a central, elevated trough of 

 Old Red Sandstone with cornstone. A dyke of trap appears at Shatterford, throwing off the 

 coal upon its eastern flank. Lower New Red Sandstone overlies the coal conformably on the 

 north, whilst other and superior members of the New Red System, flank and dip away from 

 the Old Red Sandstone to the south, in ^conformable positions. See pp. 54, 137, 178. 



Fig. 4. Repetition of the phenomena seen at the eastern end of f. 1., showing passage of coal-mea- 

 sures into Lower New Red Sandstone, with courses of impure limestone (Borle Brook.). See 

 p. 60. 



Fig. 5. Faults producing a conical mass of Carboniferous Limestone at the escarpment south of the 



Cornbrook coal-field of the Clee Hills. See p. 120. 

 Fig. 6. General Section across the Clee Hills, showing on the south an ascending series from the 

 Old Red Sandstone with cornstone, through the Carboniferous Limestone and Millstone grit, 

 to the productive coal-field. Basalt rises through the centre of these hills, capping the coai of 

 Cornbrook and the Old Red Sandstone of Titterstone Clee. In the Brown Clee Hills the Old 

 Red Sandstone (with zones of Cornstone), supports the coal-measures without the intervention 

 of Carboniferous Limestone ; the Millstone grit or " hill rock " being alone interposed. The 

 Old Red Sandstone is thrown up between the Clee Barf and Abdon Barf. The minor faults 

 in the Clee Barf are not given, but those of Abdon Barf being upcasts towards the basaltic 

 summit, are noticed. 



Fig. 7- Section across the Knowlbury coal-basin (Titterstone Clee Hill), showing the dislocations 

 by which it has been thrown into the form of a basin. The sudden expansion of the coal 

 between certain faults is a remarkable phenomenon. See pp. 114, 117- 



Fig. 8. The relations of the coal and basalt at the Hoar Edge, (Titterstone Clee), and a cone of trap 

 with dislocated coal-measures discovered in sinking a trial shaft. See pp. 113, 128. 



Fig. 9. Relations of Coal-measures and Lower New Red Sandstone on the banks of the Severn, at 

 Higley and Stanley, showing an upcast fault of the former near the river, and a further eleva- 

 tion of Old Red Sandstone on the west. (N.B. The Higley grindstone in the Lower New Red 

 was formerly supposed to be Old Red Sandstone.) See pp. 133. 



Fig. 10. Showing a thin zone of coal-measures north of Newent, interposed between the Old and 

 New Red Sandstone. See p. 153. 



Fig. 11. Great upcast of Old Red Sandstone in Fan-sir-gaer (Caermarthen-fans), to 800 feet above 

 its level in the adjacent hill of Carreg-ogof. The line of fault runs nearly from north to south . 

 See p. 165, and Map. 



Fig. 12. Repetition of upcast similar to phenomena in f. 11., but to a less extent ; the Carboni- 

 ferous Limestone not being removed on the side elevated. See pp. 157, 165. 

 Fig. 13. Fault in the Old Red Sandstone near Lydney, Gloucestershire. 



Fig. 14. General section across the Oswestry coal-field, from the Lower New Red Sandstone of 

 the plains of Shropshire, to the mountains of Lower Silurian Rocks near Llansylin. The faults
