68 is very local, being only fouundfound [sic] between Darlaston and Wolverhampton in sufficient quantity to be worth working. At Parkfields, south of Wolverhampton, the whole measure is 19 feet 2nbinches thick, with 11 bands of ironstone in it, but elsewhere, even when it occurs, it is rarely more than 2 to 4 feet in thickness.

The following are a few selected sections of this group of beds:—

(Vert. Sects., sheet 16, No. 8.)

If we proceed, from the district thus characterised, farther south, we find one or both of the ironstones quickly disappearing, and the total thickness of the beds diminishing sometimes to only 8 feet. At Highfields for instance, although there is still ironstone, the beds between the Fire-clay and Bottom coals are only two measures of clunch, with ironstone balls, each 4 feet thick.
