This instrument, as well as the two previously shown, belong to the collection of musical instruments given by Mrs. Crosby Brown to the Metropolitan Museum, New York. [Illustration: Figure 84. ORGAN IN ST. MICHAEL'S CHURCH, CHARLESTON, S. C.] This crude instrument bears testimony to years of patient endeavour. Like so many old and valuable treasures this one was harboured many years for sentimental reasons only, and because it had been given to an only daughter by her father. The story of the discovery of its value came about as follows, as told in a letter by Signor Martelli, to whose mother the piano belonged. "For the sake of economy during the time that Florence was the capital of Italy, we rented the first floor of our house, No. 3, Via del Melarancio, and occupied the second floor. In 1872 Signora Martelli (my mother) again changed her apartments from the second to the first floor, and at the moment the transfer of our furniture was taking place from one floor to the other, Prof. Cosimo Conti, a scholar and intimate friend of ours, came to visit us. The professor, who was in close correspondence with Cavaliere L. Puliti, who was spending a great deal of his time in trying to discover the origin of the piano, discovered on it to his great surprise an inscription which attested that it had been made by Bartolomeo Christofori. He immediately informed Cavaliere L. Puliti of this fact, and he came at once to examine it. Then it was ascertained that it was one of the rarest and most valuable pianos in existence. We sent at once for a tuner and had it put into good condition." The piano was bought by Signora Martelli's father, about 1819, from the Grand Ducal Palace at Siena, at an auction sale, held by order of the Minister of the Household, of all such things as he considered worthless and of no use. The piano was shuffled out of the Ducal Palace, much as some of our interesting relics have been shuffled out of the White House, and offered at auction.[1] [Footnote 1: The writer has seen a very beautiful carved and gilt round mirror, once the property of Dolly Madison, which was bought at a sale of White House furniture for twenty-five dollars.] The Christofori piano has a case of cedar, which is painted black on the outside. It stands on three clumsy turned legs. The keys are light-wood naturals and black sharps. The ivory knobs on the side blocks may be withdrawn, and the action removed from the case. There are two strings to each note, and the length of the instrument is seven feet seven and a half inches. It is three feet three inches wide at the front and nine and a half inches deep.
