_St. George’s Pottery Works._--These works were established by their present proprietor, Mr. D. W. Barker, formerly of Frome in Somersetshire, in 1869, for the manufacture of rustic ware, terra-cotta, and patent bricks--the latter being the main production of the establishment. The works are situated on Gregory’s Bank, close to the canal, on the north side of Worcester, where they occupy a large area of ground. The kilns were erected from the designs of the patentees, Hoffman and Licht, of Berlin and Dantzic, and the machinery by the patentees, Bradley and Craven, of Wakefield. As these are said to be among the best constructed of modern brick and terra-cotta works, I quote the following particulars:-- “The kiln consists of a long railway-tunnel-shaped passage, forming a long annular channel or ring. This ring is divided into twelve compartments, which may be made to communicate or to be separated from each other by the raising or lowering of a partition or damper. To each compartment there is an entrance-doorway, which can be closed with temporary brickwork. Flues lead from the bed of each compartment to the central smoke-chamber, which communicates by a main flue with the chimney. The state and progress of the fire can be at any time easily seen through the apertures on the top, down which the fuel is passed; and as the draught is under perfect control, the heat can be at once raised or lowered as may be required. The low temperature at which the gases leave the kiln is indicated by the fact that a high chimney for getting up the draught is required. There is thus a perpetual current, so to say, of bricks, which is brought slowly to revolve against, and in the contrary direction to, a perpetually revolving draught. In the green stage of the bricks they thus come in contact with air at a comparatively low temperature, and then gradually advance towards higher temperatures until they are at last burnt. Each stack of bricks to be burnt is, therefore, most ingeniously made to combine successively--(1) the functions of a grate with bars; (2) of a Leimen’s regenerator, for heating the air to be burnt; (3) of a drying-room for themselves when green; and (4) of a cooling-room for themselves when burnt. It is impossible not to enjoy the examination of such an exemplification of the dominion of mind over matter. Each day one chamber is emptied of its burnt and cooled-down bricks, and another chamber is filled with green goods. Any repairs can also be at once done to any one of the chambers as it gets emptied in its turn. In every process of treating clay or marl, with a view to drying it in the open air or to burning it, it is absolutely necessary to carry out these operations gradually at the risk of cracking and splitting the goods. This kiln, from its very gradual action and absence of
