The works at Chelsea were not finally discontinued until the year 1784, when they were destroyed by Mr. Duesbury, the kilns and every part of the work pulled down, and what was available sent down to Derby. The removal of the kilns, and the work of demolition, was entrusted to Robert Boyer, the painter, &c., the old and faithful servant whose name appears in the “weekly bills” above given; and when his work was done he removed to Derby at twenty-five shillings per week in place of a guinea, with house rent free, and fire as heretofore.[16] It is also worthy of remark that Mr. Duesbury purchased the Bow business, and owned the pottery at Pedlar’s Acre, at Lambeth, the rents of which he assigned in 1781. [Illustration: Fig. 46.] Periodical sales of stock were held in London by Mr. Duesbury, and judging by the catalogues of “Sales by Auction” by Messrs. Christie and Ansell, of Pall Mall, and “Sales by Candle,” by Mr. Hunter, the articles sent up for the purpose were excellent examples of the manufacture, and just such as were likely to be sought after by the traders--the “chinamen” of London. The descriptions of the goods were of much the same character as in the “list” referred to, with this addition, that in the late catalogues the price (the trade price possibly) was attached to each article. I have by me the priced catalogues of several years’ sales, and it is highly interesting to examine them, and to see the prices the different articles realised at the sales. They give, perhaps, one of the best insights into the porcelain trade of that period of anything I have seen. A few items, taken at random, from some of these catalogues, will be useful to the collector. The “Catalogue of an elegant and extensive assortment of Derby and Chelsea Porcelaine” for sale on May 10th, 1781, and four following days, has a long and full title-page, and occupies thirty-two octavo pages. The company were invited to this sale by cards, of which the following is a copy:-- “At Mess^{rs} Christie and Ansell’s great Room, next _Cumberland House, Pall Mall_, will be sold by Auction on _Tuesday_ next, the 7th of _May_ 1782, and the Four following Days, an elegant and extensive Assortment of the DERBY and CHELSEA PORCELAIN, consisting of TABLE and DESERT SERVICES, TEA and COFFEE EQUIPAGES, BISCUIT ORNAMENTS, &c., &c. “To be viewed on _Saturday_ the 4th of _May_, and till the Sale (Sunday excepted), which will begin each Day at 12 o’clock. “N.B.--Mr. _Duesbury_ flatters himself the Produce of his Manufactory this Year will be found far superior to any Thing he has ever yet exhibited, and therefore humbly hopes he shall experience the wonted generous Countenance of the Nobility, and his Friends in general, whose Patronage (with the highest Sense of Gratitude) he will be ever studious to deserve.”
