Many secret processes are employed to impart an appearance of age to the wood and to the metal mountings. The cruder methods are to eat off the sharper edges of the metal mountings by means of acid, and to discolour the newer surfaces by the aid of tobacco juice, both of which are not difficult to detect. The steady manufacture of these finer pieces goes on in France, and it has been found that the foggy atmosphere of London is especially useful in producing the effect of age upon the finer work, consequently many forged pieces are shipped to London to be stored in order to ripen until considered fit for the American market, where so many forgeries have been planted. The reward is great, and even considering the amount of trouble bestowed upon such pieces and the excellence of the artistic work where the highest skilled labour is employed, the profit is enormous. The parvenu buys his Louis XIV. or Louis XV. suite, and pays an immense sum for pieces which are stated to have come from some French nobleman's chateau, whose name must not be divulged, and so the interesting deal is brought to a successful termination. [Illustration: "MADE-UP" BUFFET. The middle portion, consisting of the two drawers and three panelled cupboards above, is genuine old carved oak. The stand, with the finely turned legs and rails, and the whole of the upper portion, is modern.] As an object-lesson as to the truth of the above remarks, the Wallace Collection contains a modern French copy in facsimile, by Dasson, of the celebrated "Bureau du Roi" of the Louis XV. period, the original being in the Louvre. The original is fully described in the chapter on Louis XV. style, and it is not too much to assert that ninety-nine per cent. of the visitors to the Collection could not say that this copy was not an old French specimen of over a century and a quarter ago, and the remaining one, unless he happened to be an expert, would not question its genuineness.
