"Vol. 69.] SERIES OF THE SOUTH STAFFORDSHIRE COALFIELD. 445 



The red beds seen near Jlley Mill have already been assigned to 

 the Hasbury Group (p. 444). Grey and olive-coloured shales and 

 sandstones follow these in ascending sequence in the Illey stream- 

 courses. The ' coaly beds ' have not been located by me, unless 

 these be identical with thin Coal-Measure binds recently exposed 

 in a roadside-cutting at Lower Illey. In this exposure a sharp but 

 low anticlinal fold is seen, and the binds are overlain by massive, 

 ■ coarse, brown grits. Similar grits are found at Cooper's Wood, 

 farther east, where they overlie thin shaly sandstones from.which 

 I obtained an impression of ? Pecopteris. In Kettle's Wood the 

 grits pass beneath bright-red marls belonging to the Keele Series. 



The true base of the Illey Group would appear to be certain grey, 

 yellow, or blue clays and shales containing earthy Spirorbis Lime- 

 stone, and seen immediately above Illey Mill. Clay-land extends 

 from this point north-eastwards to near the Lappal Tunnel, and 

 north-westwards towards The Grange. 



In the Stour Glen, west of the last-named point, and reaching 

 as far west as TJffmoor Wood, pale-blue or yellow clay is strongly 

 in evidence. In Uffmoor Wood a thin coal appears in the bed of 

 • a stream, but this has not been found elsewhere. Still farther 

 west the whole group disappears beneath the bright-red clays of 

 the Keele Series. 



I have not traced the upper boundary of the group between the 

 Gypsy's Tent and Lower Illey, the line laid down by Jukes, Ramsay, 

 and Hull having been accepted for the present. 



There remains to be noticed the remarkable exposure of bright- 

 red sandstones found on Quarry Hill, south of Hasbury, and 

 formerly mapped as Permian strata. These beds yield good 

 bailding-stone, and have been extensively quarried. They are red 

 in external appearance only, since the blocks obtained from them 

 are either red, variegated, or creamy brown. Bright-red marl is 

 found in the rock-crevices, together with crystalline calcite. The 

 rock-partings are formed of dull-red marl mingled with coal-dust 

 and white ash, or wholly of transported coaly material, in which 

 case they appear as coal-seams a few inches thick. Rounded lumps 

 of coal, of lignite, of red and yellow ochreous material likewise 

 occur, together with rolled pith-casts of Catamites and other Coal- 

 Measure fossils. 



At the base of the new quarry a lenticular bed of dark, tough, 

 calcareous sandstone occurs. Quite recently a slab of this rock was 

 raised, to the under side of which pale-blue clay was found ad- 

 hering, and I was informed that clay of this kind underlies the 

 whole quarry. It was stated that on the northern side it was but 

 an inch or two thick, though it was 15 inches thick in the south- 

 eastern corner. The beds dip at 15° to 20° south-south-eastwards. 

 The slope of the hill, however, is greater still, with the result 

 that the clay reappears in the valley below, where it is widely 

 exposed, as already shown. 



It is, therefore, clear that the beds seen in these quarries are
