Two other marks, the one a _D_ surmounted by a crown, and the other an anchor, similarly surmounted, are said to have denoted respectively the articles made at this period at Derby and at Chelsea (Figs. 59 to 63). Now and then the first of these is met with in connection with the anchor (Fig. 63). [Illustration: Figs. 62 to 67.] The most usual mark is that of the letter D, with crossed swords, dots, and crown, of which several varieties occur. Sometimes the initial is the writing letter _D_, and sometimes a Roman capital D, and the crown also varies according to the caprice of the painter. Figs. 64 to 67 show some of the varieties. [Illustration: Fig. 68.] A variety of this, in which a _D_ and a _K_ are conjoined, denotes the period when the works, in their later days, were carried on by Duesbury and Kean. It was, however, only very sparsely used. For some years, at all events up to about 1825 or 1830, Mr. Bloor continued to use the old mark of the Duesburys--the crown, cross daggers with dots, and D beneath--but about that period discontinued it, and adopted instead a mark with his own name (Fig. 68). It is well to note, that down to the discontinuance of the old mark, it had invariably been done with the pencil, _by hand_, but that those adopted by Mr. Bloor were _printed_ ones. The first printed mark I believe to be Fig. 69, and somewhat later the same was used, but slightly larger in size (Fig. 71). Other marks are shown on the engravings. Figs. 74 and 75 have an old English [Illustration: D] surmounted by a crown; another (Fig. 76) a crown, with a riband bearing the word DERBY in Roman capitals beneath it. [Illustration: Figs. 69 to 73.] [Illustration: Figs. 74 to 78.] Other marks, said to have been for one purpose or other--of course as imitations--used at Derby, are the following:-- [Illustration: Figs. 79 to 84.]
