fragments, though still fairly angular, as a rule do not exceed 

 2 inches in length, and there is very much marl. 



North and south of Buckpool are good sections of the breccia 

 in stream-courses, where 90 per cent, of the material is less 

 than 1 inch square. The proportion of marl is very large. Tlie 

 largest rock-fragment that I have seen is 9 inches long, and very 

 much rounded. Pieces more than 3 or 4 inches long, however, are 

 exceptional, and are generally much worn. Several bands of breccia- 

 sandstone are interstratified with the breccia. 



At Buckpool the exposed thickness of the breccia and intercalated 

 sandstones is about 150 feet. The marls 0^ crop out, and thus the 

 thickness can be measured. 



At Cient Hill, as already stated (p. 112), the Llandovery sandstone- 

 fragments, embedded in the breccia, are very common, large (up 

 to 15 inches long) and angular, while fragments of the same rock 

 are in that part of the Stour Valley district which lies north of 

 Chawnhill exceedingly rare, small (2 inches long) and rounded. 



In the Baggeridge-Sedgley area there is a little hill, | mile south- 

 west of Sandyfields, the top of which is an outlier, 1 X | furlong 

 in extent, of breccia-sandstone (20 to 30 feet thick), like that 

 in the north-west of the Envilie district. The trappoid breccia has 

 ceased to exist. Therefore, when the coarse Clent Hills breccia is 

 followed northward for 8 miles, it is seen to become gradually 

 finer, ultimately passing into sandstone. 



2c. The Warley-Barr District. (PI. XII.) 



It now remains to deal with the north-eastern branch of the 

 Middle and Tipper Permian rocks that occur on the eastern side 

 of the coalfield. This district, from south to north, is 8 miles long, 

 ranging from Quinton to Great Barr. It may be regarded as made 

 up of three areas : — 



(i) The Warley area at the southern end, commencing at 

 Qainton, about 2 miles north of the breccia at Ley Hill, Northfield, 

 and extending for more than 2 miles to beyond Langley. It is 

 nearly a mile broad, from east to west. The Middle and Upper 

 Permian rocks of this area are faulted against the Carboniferous on 

 the west, and the Bunter conglomerate rests unconformably upon 

 them on the east. 



(ii) The Handsworth area lies north of this, and is situated 

 about the centre of the district as a whole. 



(iii) The Barr area is at the extreme north of the main 

 district. 



The Middle Permian of the "Warley-Barr District. 



(i) The Warley area. — Two calcareous zones may be followed 

 in this area, continuously from Brand Hall to Langley, a distance of 

 1| mile. The lower and westernmost zone, which I provisionally
