The marks used at Caughley and Coalport have been very few, but they are very important, and require careful attention at the hands of the collector. In my account of the Worcester works I have given several varieties of the _crescent_ as a mark of that establishment, and have also stated that it was used at Caughley. I believe the first mark used at Caughley to have been the crescent alone, and that it was, as I have before stated, intended to have the signification of a C for Caughley, and that its connection with the Worcester works may, in a great measure, be traced to the fact of the goods on which it appears being printed, not at that city, but at Caughley. I have seen examples of this mark on undoubted Worcester body, and also on equally undoubted Caughley make, bearing precisely the same printed patterns. The following are some of the varieties of the crescent occurring on Caughley specimens, and show pretty clearly its transition from a common “half-moon” (I have often heard it called “half-moon china”) to the finished and engraved C. [Illustration: C C’ C C c Figs. 588 to 592.] Another mark said to have been used at Caughley, but of which at present I have met with no example, is the accompanying, [Illustration: Fig. 593.] which is very similar to the mark ascribed to the Leeds manufactory. Another distinctive mark of the Salopian works was the capital letter S, of which the following are varieties:-- [Illustration: S S Sx S^x So S S Figs. 594 to 600.] When the S was introduced it is difficult to say; but, at all events, it appears on the dated example alluded to above in 1776, and it was used at the same time as the C for a considerable period. On many of the engraved plates still in existence, indeed, both the C and the S occur, and this leads me to suspect that the one was used to mark the goods sent to Caughley to be printed, and the other those made and printed for their own market. I have seen precisely similar articles in pattern, bearing each of these letters. Occasionally the S and crossed daggers occur. [Illustration: Vol.I. PLATE III. ORIGINAL COPPER-PLATES--CAUGHLEY AND COALPORT. (The letters C and S are the marks alluded to on page 270; they here occur side by side on the original copper-plate.)] Another circumstance is also worthy of note. On two mugs printed from the same engraved plate, which I have seen, the one bears the S, and the other the accompanying curious mark (Fig. 598), which is evidently of the same character as the examples of assimilated Chinese ones, which are occasionally ascribed to Worcester, but which are in reality, I believe, those of Caughley. Of these I give the following as examples; many of these are disguised figures. [Illustration: Figs. 601 to 606.] Following the C and S, two _impressed_ marks, bearing the word “Salopian,” were used. These are as follows:-- [Illustration: Figs. 607 and 608.]
