If miles from the second and nearly 300 feet vertically above it,^ 

 and both of them were about five miles from the third. The following 

 is an abstract of my notes : — 



(1) Near the top of Style Cop. The pit is on two levels. The face 

 of the upper one, about 7 feet high,^ showed a mass of pebbles 

 embedded in sand, generally uniform, but with local indications of 

 false-bedding and one or two horizontal streaks of sand. That of the 

 lower pit (practically continuing the other and about the same vertical 

 height) displayed alternating bands of pebbles (the thickest, with an 

 intermittent sand-parting, being about 3 ft. 6 in.) and false-bedded 

 sands witb occasional stones. The pebbles throughout range up to 

 about 4 inches in diameter, but the majority are considerably below 

 this. The flatter specimens usually lie witb their longer axes 

 horizontal. Commonly there is plenty of interstitial sand, amounting 

 perhaps to one-third of the whole mass, the larger pebbles as a rule 

 not touching one another. 



(2) Pits near Baland's Pool : («) N'ear the Waterworks. Section about 

 18 feet in height; practically continuous gravel, sand-bands being 

 almost absent : stones varying from small to large, the latter in a few 

 cases exceeding 6 inches in diameter. False-bedding of coarse and fine 

 gravel, or ' pockets,' two or three feet across, of small stones, with 

 little iiaterstitial sand, occur in places, but the latter are quite local, 

 and, except in them, there is plenty of a rather muddy-looking sand 

 between the stones. — (h) By the side of the Rugeley and Cannock 

 railway. A cutting, perhaps 200 yards from end to end, and over 

 40 feet in the highest part, its base being concealed by talus. At the 

 top is a continuous mass of pebbly gravel, about 5 yards thick ; 

 beneath it, for about 8 yards, is a gravel similar, but interrupted 

 by sand-bands, sometimes extending horizontally for dozens of yards 

 and attaining a maximum thickness of about 4 feet. There is plenty 

 of sand among the pebbles. The whole mass has a conspicuous 

 ' horizontal ' aspect, and very closely resembles some of the old river 

 gravels in the outer zones of the Alps. 



(3) Pits on Satnall Hills, northern side of the Eugeley and Stafford 

 road : («) Nevett's pit.^ Yertical section at highest point more than 

 30 feet. At the top is a thick bed of gravel, with occasional thin 

 bands of sand. Below that is a well-defined band of the latter 

 (maximum thickness about half a yard). Then come about 5 feet of 

 well-bedded, rather sandy gravel, resting on another sand-band, nearly 

 2 feet in greatest thickness, and under it about 7 feet of gravel 

 (pebbles as a rule under 3 inches), generally conspicuously false- 

 bedded, but less so in the last foot, after which another thick bed of 

 gravel, with larger pebbles and more or less definitely horizontal 



1 The height of Style Cop is 721 feet (the pit is slightly lower). The road by the ■ 

 Waterworks, a few feet below the second pit, is 418 feet above sea-level. I should 

 estimate the altitude of the Satnall Hills pits to be about the same. 



2 The measurements throughout these notes are only estimates. It would not 

 always have been possible to apply a tape, and as the weather was cold it was, not 

 worth risking a chill for the sake of a useless precision. 



^ In this pit my nephew, (now) Lieut. F. G-. C. Wetherall, found that fossiliferous 

 pieces of Carboniferous Limestone were less rare than usual.
