Mr. G.P. Putnam announces as in preparation for speedy publication a series of Manuals for popular reference, designed to compress into a compact form a comprehensive and accurate view of the subjects of general history, science, literature, biography, and the useful arts. They are to be prepared by authors of undoubted qualifications, on the basis of Maunder's and other recent compilations; and to be published in a style uniform with the "World's Progress." The office of a compiler and classifier in literature assumes a new importance, and has new claims upon the gratitude of the student, in these days when the life of a man is too short for him to make himself acquainted, from the original sources, with any one branch of knowledge. The same publisher also announces a "Life of Washington," by WASHINGTON IRVING; "The Monuments of Central and Western America," by FRANCIS L. HAWKS, D.D.; a "Commentary on Ecclesiastes," by MOSES STUART; and new works by Dr. MAYO, Author of "Kaloolah," by J. FENNIMORE COOPER, Hon. E.G. SQUIER, and the Author of "Rural Hours." The Opera has not had the success of last season, in spite of the addition of Signorina PARODI to the company of last year. Parodi is admitted to have a remarkably fine voice, and to be not without dramatic talent, although prone to exaggeration, but she is not generally thought equal to the claims set up for her, and, what is of more importance, she does not fill the house so well at two dollars and a half as was expected. Toward the end of her first series of performances at New York she drew quite large audiences, and made many admirers among persons of acknowledged taste. A project is on foot to build a very large Opera House near the site of the old one. The proprietors are in Paris, we believe, and they hope to join MARTI, the great Havana manager, with them. The undertaking is based on the supposition that in this country it is better to appeal to the many than the few. The basis is good, where the many have the taste to which to appeal; but an opera audience must be a steady one, and it remains to be seen whether a taste for the opera is yet sufficiently diffused here to insure large audiences always, at remunerating prices. The Havana company do not make their expenses on their summer visits, even at Castle Garden, but in the summer all that they receive is gain.
