Still farther south, what is probably the Brock Hall Coal was worked at Earnwood 

 and the Birch. The Main Sulphur Coal should crop farther west, somewhere in the 

 position assigned to it upon the map (text-fig. l) ; but little 

 or nothing is known of it till we reach Winwoods and 

 Kingswood, where it was worked at a depth of about 25 

 yards. The ^n'roWn's-limestone must have been passed 

 through in the shafts, as pieces of the stone are to be seen 

 at the pit-mouths. 



The seams worked at Baveney Wood were sweet coals ; 

 and it is significant that they are said to have shown signs 

 of having deteriorated in number and thickness as compared 

 with their development at Harcott and Billingsley. A coal 

 cut through by the Birmingham aqueduct at Silligrove was 

 said to be a sweet coal, and Mr Daniel Jones noted a coal- 

 crop, which he believed to belong to the Sweet Coal Measures, 

 in a cutting on the Tenbury railway opposite Furnace Mill. 

 These outcrops may be a southerly extension of the Sweet 

 Coals of Baveney Wood. Still farther south, in the Dowles 

 Valley region, no such sweet coals are known ; and their 

 absence may be due to their having become unworkable or 

 to their having thinned out completely, as is suggested in 

 the diagram forming text-fig. 3. 



East of Winwoods and Kingswood, the Main Sulphur Coal 

 was worked below the Spirorbis -limestone by pits at Button 

 Oak, from which point its outcrop is apparently shifted 

 northward by a fault, and what is believed to be this coal 

 is exposed in a cutting on the Severn Valley railway a few 

 yards south of Arley Station. It then crosses the Severn 

 and runs through Eymore Wood to Shatterford, the outcrop 

 being marked by numerous old pits. At Shatterford it 

 was worked at a depth of 176 yards; but a deep sinking, 

 carried down below the sulphur coals in 1850-60, though 

 it proved a great thickness of measures, failed to prove 

 any sweet coals worth getting. It was probably the 

 Main Sulphur Coal that was worked in pits and drifts 

 east of Brettels. Beyond this point nothing is known of 

 it ; but it presumably turns round the end of the Trimpley 

 anticline and is then cut off by the faulted margin of the 

 Keele Beds. 



In the Mamble region the Main Sulphur Coal, which 

 appears to be represented by two seams separated by about
