4th. A collection of plaster casts of all the best works of sculpture, particularly of the antique. Correct casts of the Elgin marbles are sold by the British Museum at a very reasonable price, and in this case would doubtless be presented to the institution. 5th. A collection of Paintings. This is the most difficult part of the project, yet practicable. Masterpieces of the art only should be admitted, but historical authenticity disregarded. The works of the great masters have been so closely imitated, that there are no certain marks of authenticity, where the history of the picture cannot be traced. (See Spooner's Dictionary of Painters, etc., Introduction, and Table of Imitators.) Half the pictures in foreign collections cannot be authenticated, and many of those which are, are not the best productions of the master, nor worthy of the places they occupy. (See Mrs. Jameson's Hand-Book to the Public Galleries in and near London; also the Catalogues of the various Public Galleries of Europe.) Therefore, instead of paying 5,000 or 10,000 guineas for an authenticated piece by a certain master, as is sometimes done in Europe, competent and _true_ men should be appointed to select capital works, executed in the style of the great masters. Many such can be had in this country as well as in Europe, at moderate prices. 6th. The Institution should be located in New York, as the most convenient place, and as the great centre of commerce, where artists could most readily dispose of their works. For this favor, the city would doubtless donate the ground, and her citizens make liberal contributions. The edifice should be built fire-proof, and three stories high--the upper with a skylight, for the gallery of paintings. Such an institution need not be very expensive; yet it would afford the elements for the instruction and accomplishment of the painter, the engraver, the sculptor, the architect, the connoisseur, the archaeologist, and the public at large; it would be the means of awakening and developing the sleeping genius of many men, to the honor, glory, and advantage of their country, which, without it, must sleep on forever. See vol. ii., pp. 149 and 155, and vol. iii., p. 265 of this work. INDEX. Advantages of the Cultivation of the Fine Arts to a Country, i, 6; Sir M. A.
