The next coal there below this Stinking coal is a coal which we shall afterwards prove to be the top of the New Mine.

There can be little doubt that the beds containing ironstone which come above this Sulphur coal are the representatives of those just described as the Pennystones and New Mine ironstones, and that the coal No. 13 is the true Heathen coal; while the beds numbered 9, 10, and 11 are probably the little Gubbin ironstone and coal, as it makes its appearance at Bentley; and coal No. 7 is the Bind coal which comes in at Bentley with the same thickness, but associated with ironstone.

23. Beds between the Sulphur and Xew mine coals.—In the Priestfield colliery between Bilston and Wolverhampton there is in one pit 99 feet of binds and rock in this position, and in all the adjoining collieries there are 70 feet or 80 feet of the same materials, the sandstone predominating and passing under the name of the New-mine-coal rock, or the Twenty-yard rock. This mass of rock is variably split up with rock -binds and peldon, sometimes with clunch. There is often above it a bed of fire-clay or of clunch a few feet in thickness, supporting the Sulphur coal, but that is frequently absent, and that coal rests directly on the sandstone. Going north towards Bentley the thickness of these measures diminishes to about 30 feet or 40 feet. Going south from Bilston they are still 70 feet at Highficlds, consisting of rock and peldon; but at Deepfields there is only 5 feet of fire-clay and 40 of binds, and at Tipton Green but 15 feet of rock, which at Foxyards
