Force, of Washington. The latter was the largest private library ever then brought together in the United States, but its chief value consisted in its possession of a very great proportion of the books relating to the settlement, history, topography, and politics of America, its 45,000 pamphlets, its files of early newspapers of the Revolution, its early printed books, and its rich assemblage of maps and manuscripts, many of the latter being original autographs of the highest historical interest, including military letters and papers of the period of the American Revolution. The Smithsonian library, the custody of which was accepted by Congress as a trust, is rich in scientific works in all the languages of Europe, and forms an extensive and appropriate supplement to the Library of Congress, the chief strength of which lies in jurisprudence, political science, history, and books relating to America. Yet no department of literature or science has been left unrepresented in its formation, and the fact has been kept steadily in view that the Library of the Government must become, sooner or later, a universal one. As the only library which is entitled to the benefit of the copyright law, by which copies of each publication for which the Government grants an exclusive right must be deposited in the National Library, this collection must become annually more important as an exponent of the growth of American literature. This wise provision of law prevents the dispersion or destruction of books that tend continually to disappear; a benefit to the cause of letters, the full value of which it requires slight reflection to estimate. This National Library now embraces 840,000 volumes, besides about 250,000 pamphlets. It is freely open, as a library of reference and reading, to the whole people; but the books are not permitted to be drawn out, except by Senators and Representatives and a few officials for use at the seat of government. Its new, commodious and beautiful building, which may fitly be called the book-palace of the American people, open day and evening to all comers, is a delight to the eye, and to the mind. * * * * *
