The Authors' Reading at Sander's Theatre, in aid of the Longfellow Memorial Fund, on the evening of the poet's birthday, Feb. 27th, promises to offer an unusually attractive programme. The object for which the entertainment is to be held is so worthy of encouragement, and the interest in the matter is so great, that the affair cannot fail to be a success. Several well-known authors have shown their interest by offering to read selections from their own works. Among them are the following: Julia Ward Howe, Edward Everett Hale, Thomas Wentworth Higginson, William Winter, Louise Chandler Moulton, John Boyle O'Reilly, George Parsons Lathrop, Charles Follen Adams and Charlotte Fiske Bates.
