MOSCOW.--In 1830 some porcelain was made at Moscow by A. Popoff, a piece of which is in the South Kensington Museum, marked with his name in Russian characters. There seems also to have been porcelain made at Moscow by M. Gulena, of which little is known. His mark was the initial letters of Fabrica Gospodina, and his own name, in Russian characters. [Illustration] POLAND.--At Korzec, in Poland, in 1803, a Frenchman named Mérault, from Sèvres, made porcelain for a few years, probably in small quantity; and a mark upon some pieces of his is a triangle containing an eye. CHAPTER XVII. POTTERY AND PORCELAIN IN THE UNITED STATES. The First Porcelain made here.--Bonnin and Morris.--Franklin Institute.--William Ellis Tucker.--Tucker and Hemphill.--Thomas Tucker.--General Tyndale.--Porcelain of T. C. Smith and Sons.--Early Advertisements.--Josiah Wedgwood.--Lord Sheffield's Report.--Alexander Hamilton's Report.--History of Norwich.--Samuel Dennis, New Haven.--Isaac Hanford, Hartford.--Gallatin's Report.--The "Washington Pitchers."--Lyman and Fenton, Vermont.--Rouse and Turner, New Jersey.--Potteries at Trenton.--In Ohio.--The Centennial Exhibition. Doubts have been expressed whether PORCELAIN was made in the United States as early as 1770; though there was no question as to the existence of the true china-clays, and that Wedgwood and other potters in England knew of them and had used them. More, they were fearful that they would be put to use in this country, to the injury of their trade. The investigations of Charles Henry Hart, Esq., of Philadelphia, seem to remove the doubt as to the making of porcelain in that city as early as 1769 or 1770. Looking over the newspapers, he finds, under date of December 29, 1769, an advertisement as follows: "NEW CHINA-WARE.--Notwithstanding the various difficulties and disadvantages which usually attend the introduction of any important manufacture into a new country, the proprietors of the china-works now erecting in Southwark have the pleasure to acquaint the public that they have proved to a certainty that the clays of America are productive of as good PORCELAIN as any heretofore manufactured at the famous factory in Bow, near London," etc. Subsequently other advertisements appeared for apprentices, etc., signed by G. Bonnin and G. A. Morris. This would seem conclusive. Mr. Hart also states that some specimens of the work then made are deposited in the Franklin Institute of his city. It is not likely that the work reached a commercial success, or that it was long continued. Subsequently porcelain was made and decorated in that city by Messrs. Tucker and Hemphill, as will clearly appear from the following communications. Mr. Thomas Tucker prepared for the Historical Society of Pennsylvania, in 1868, this brief statement:
