DESCRIPTION OF THE SECTIONS. 



Fig. 5. Section across the Hayes near the south-western end of the Dudley coal-field, exposing a 

 narrow ridge of Ludlow Rocks, including beds of limestone, flanked by highly inclined coal 

 measures. See p. 483. 



Fig. 6. Section to prove, that as the 10-yard coal ranges up to the southern limit of the coal-field 

 and is lost by a fault only, there is every reason to conclude, that the same thick coal will be 

 found at a lower level beneath the Lower New Red Sandstone and beyond the fault. The ex- 

 tent of the fault is of course hypothetical. See p. 506. 



Fig. 7« From the trap of Lickey Beacon on the west and by north, across the Lower Lickey quartz 

 ridge on the east and by south -, showing how the altered Caradoc Sandstone, and an overlying 

 band of impure limestone, pass beneath a thin course of coal, and the latter under the Lower 

 New Red Sandstone. See pp. 57, 492 et seq. 



Fig. 8. From the hill south of Lickey Beacon, on which Lord Plymouth's monument is placed, to 

 the Lower Lickey quartz ridge, to show a dip of the quartz rock directly the reverse of that in 

 fig. 7* (a parallel distant half a mile only). The Lower New Red Sandstone at its junction 

 with the quartz rock shows symptoms of having been partially disturbed, as in PI. 36. figs. 5 

 and *]. 



(In figs. 7 and 8, the numerous joints transverse to the laminae of deposit which characterize 

 the quartz rock are indicated by dotted lines.) See pp. 57, 492 et seq. 

 Fig. 9. Nucleus of trap (compact felspar rock) between Kendal End and Barnt Green, marking 

 the termination of the Lower Lickey Ridge, and explaining that the quartz rock here, as at the 

 Caradoc and Wrekin, (PI. 29. f. 11. and PI. 31. f. 4.) is a Lower Silurian Sandstone altered by 

 volcanic action. See p. 495.
