are exposed, and though the section is abnormal, the measures being 
much compressed and brought exceedingly close together, it is a 
highly interesting one. Above the Flint and Clod-coal we see the 
‘Best’ Coal, ‘Game,’ ‘'Two-foot,’ and ‘Lower Sulphur’ Coals; and 
above the last, the ‘Penny-stone’ Iron-measure, capped by a bed 
of sandstone, which has been employed in building the bridges, &c. 
on the railway. In a brickfield about 100 yards to the north still 
higher strata are exposed, viz., Red Brick-clay, 8 feet; White 
Clay, 12 feet ; Mottled Clay, solid below, sandy above, with, nodules 
encrusted with iron (‘snake heads’), and then the true * Sulphur’ 
Coal, or ‘ Stinkers,’ usually found, as here, 9 or 10 yards above the 
« Penny-measure? Thus in a walk of little more than a mile we 
may see in open sections the whole of the Lower Coal-measures and 
a portion of the Upper. 
For a detailed account of the Shropshire Coal-field, the estuarine 
character of its strata, and its peculiar fossils, including several 
species of Insects and of the Limulus or King-crab, the reader is 
referred to Prestwich (Trans. Geol. Soc. 2nd ser. vol. v.), Hull, and 
the Publications of the Geological Survey.
