Book excerpt: Excerpt from The Mining Magazine, Vol. 2: Devoted to Mines, Mining Operations, Metallurgy, &C., &C.; From January to June, 1854 In Shropshire, from the nature of the coals and ironstones, their roofs and other peculiarities, the most perfect instances of what is termed long work may probably be found. Seams of considerable thickness are there worked in one long wall of great extent. The roads or ways of the mine are maintained by the rebuilding or stowing of those portions of the seam which are of no value, or of the fallen roof. These roads are carried to the face of the works in the whole coal, in directions radiating from the shafts to which the mineral has to be brought, and they pro gress as those works become more distant.
