Now if with that section we contrast the following one, found in sinking the new Baremoor pit, we shall at once see the whole amount of the change:—

This 9-foot coal was then worked, and it was said to thin out in every direction by the gradual bending down of its roof, till it was no longer worth following. The shaft having been continued into the Whitestone measures without finding any more Thick coal, and the two Heathen coals having been found lying regularly below, they then proceeded to drive gate-roads (or galleries) from the surrounding excavations in the undiminished Thick coal towards this new Baremoor shaft. In so doing they discovered the nature of the mass of interposed sandstone; and in the year 1849 they had already worked round three sides of it, and thus partially proved its extent.^[2] They found it to be an oval cake of
