examination of the fossil plants collected while sinking 
through these rocks at the Sandwell Park trial boring ne 
West Bromwich, and in the sinking of the shaft of the 
Hamstead Colliery, Great Barr, near Birmingham—that 
this series is not Permian but belongs to the Upper Coal- 
Measures. It had previously been conjectured that these 
rocks were of Coal-Measure age by Messrs Meacham and 
Insley.t_ The fossil plants collected at the above two work- 
ings will be referred to later on.’ 
The occurrence, therefore, of a small coal seam in the shaft 
at Bullock’s Farm, near Spon Lane, South Staffordshire, is 
not at all unusual, when it is shown that the strata passed 
through are Upper Coal-Measures and not Permian, as 
originally supposed.* 
Passing on to North Staffordshire, in the Potteries Coal 
Field, we again meet with these red shales, ironstones, and 
coals containing Upper Coal-Measure plants. A higher 
series of rocks, supposed to be Permian, overlies them. There 
is no break between the two series, and it seems highly prob- 
able that the whole are Upper Coal-Measures. There is no 
character, lithological or otherwise, so far as I know, by 
‘which they can be separated. 
Carrying our investigations still farther north, into 
Lancashire, we find red shales and sandstones forming the 
Upper Coal-Measures of the Lancashire Coal Field. 
In Yorkshire we likewise find, at Conisborough Pottery, 
what are most probably, if not certainly, Upper Coal- 
Measures, represented by red shales. This has been assigned 
to them as their probable age by Professor A. H. Green and 
Mr R. Russell.* 
It is seen then, that these red shales and associated sand-

also been pointed out to me that these ches have been coloured as Coal- 
Measures in the map which accompanies the 2nd edition of H. M. Wood-

Messrs Goodchild and Woodward.
