In addition to this I give a communication from General Hector Tyndale, which adds confirmation to the above: "About the years 1760 to 1770 potteries were established in the United States--notably at Philadelphia--of which few records now remain. But they attracted the attention of the English potters, as may be seen by a letter from Josiah Wedgwood (page 367, Meteyard's 'Life of Wedgwood,' London, 1865), wherein he expressed apprehension of the effect of these upon British 'trade and prosperity.' "Porcelain-works, to which Mr. Elliott alludes, were established in Philadelphia (corner of Schuylkill Sixth and Chestnut Streets) about the year 1830, Judge Hemphill being among the most prominent of the founders of them. The wares made were of very good, and, in some respects, of excellent qualities. The products were white and decorated table and tea services, and decorative wares. The 'body' was very good, being hard, dense, tough, and translucent, quite vitreous, with sharp and clear ring, and withstanding great and rapid changes of temperature. In appearance it somewhat resembled the French (Limoges) porcelain of that day, and, in durability and use, that of Berlin, and quite equal to either. The glaze was good, and well adapted to receive colors. The forms were copies of the French and English of the time, and these were almost always bad. The ornamentation was generally poorly copied from the English or French, or, if original, was decidedly worse. English, French, and German artisans were imported, but whatever skill these may have had was soon lost, owing perhaps to the want of comparative and competitive productions, and also to the want of taste among the general buyers and the public. So far as ornament was concerned, and a knowledge of æsthetic rules or a prevailing _sense_ of beauty and fitness were involved, this attempt at manufacture was premature. These works continued, with a diminishing success, for several years; and the founders, who lost much money in the establishment, deserve much credit for their serious and wellnigh successful effort. "At present there are porcelain-works near New York--at Greenpoint, and perhaps elsewhere--making very good and enduring wares, of excellent 'body' and glaze, but of coarse and inartistic form and ornament." The porcelain-factory last spoken of is that of T. C. Smith and Sons, which, at the Centennial Exhibition, made a creditable display. Through the courtesy of Mr. Prime, editor of the "Hand-Book of the New York Museum of Art," I am able to give some extracts essential to this brief history:
