The results of these experiments have been illustrated in an extensive series of specimens of the clays or plastic slates of Great Britain presented by Mr. Geo. Maw, F.S.A., to the Government Museum of Practical Geology, in Jermyn Street, and printed in the supplement to the catalogue by Sir H. De La Beche and Mr. Trenham Reeks. In 1857, after all these years of patient labours, the manufacture was commenced on a commercial scale, which for several years barely paid its expenses; but from that time to the present continual additions have been made to the works to meet the increasing demand for their productions. In 1871 supplementary works were commenced at the Tuckies, about two miles from the Benthall works, celebrated as the spot where the late Lord Dundonald carried on his experiments in the manufacture of coal-gas.
