The Managers of the Fair invite all Merchants, Manufacturers, and Artisans to contribute of their wares to its stores, giving such goods as they make or deal in--such goods as are made profitable to them by the prosperity of the country which our soldiers are fighting to maintain. Painters and Sculptors, who have done so much for the honor of their country, all who are connected with the Fine Arts, either as creators, as dealers, or possessors of Art Treasures, are asked to send their contributions for _exhibition_ or _sale_. Farmers are invited to bring to the Fair gifts from their barns, stalls, dairies, and poultry yards. Publishers and Booksellers are confidently looked to for aid. A _Second-hand Book Stall_ will be attached to this Department, to which contributions are asked from the shelves of those who are cumbered with duplicate copies, or who have books which they no longer use. Connected with this Department will be a table for the exposition and sale of valuable Autographs. On the Musicians, Musical Instrument Makers, and Music Dealers, the Managers confidently rely for a worthy representation of the beautiful art of which they are ministers, by the giving of Musical Performances and of instruments and music for sale. The Managers and Artists of the various Theatres are invited to set apart one evening during the Fair, the performances on which shall be for the benefit of the fund. It is hoped that the Public Schools and Public Institutions of a benevolent character may contribute in some fitting manner to the Fair. It is also hoped, from the well-known patriotism of the Fire Department and the Police, that they will bear an honorable and conspicuous part in this life-preserving and humane undertaking. A Department of Arms and Trophies will be established, to which not only arms and flags captured in the present war, but all articles of this kind having a historic or intrinsic interest, will be acceptable contributions, either for sale or exhibition. An Old Curiosity Shop will afford all who have interesting relics of the past in their possession an opportunity to enable others to share the pleasure of examining them. Valuable contributions have been already received in this department. Let it be clearly stated whether articles of this kind are for sale or only for exhibition. A Newspaper will be published daily, which, in addition to the latest telegraphic news, will contain short and piquant articles upon the incidents of the day, and especially of the Fair. A Post Office will also be established. A Restaurant will be under the charge of an accomplished public caterer. It is intended that, so far as practicable, each city in the State desiring that its contributions shall be kept together, shall have a separate space set apart for them, and that each of these cities shall be represented in the General Committee of Management.
