We will leave the attempt to trace these beds south and west of Dudley till after the description of the Fire-clay coal. Going north from the district already described, (north of Willenhall that is,) we find these beds to have a more constant character than elsewhere, always preserving a thickness of more than 20 feet, and consisting of alternations of rock, fire-clay, and clunch, as the three following sections will show:—
