"It is precisely the book which ought to have a very wide sale in this country--a book which one needs to own rather than to read and lay aside. No common-school library or collection of books for young readers should be without it."--_The Churchman._ "These names are in themselves sufficient to guarantee adequacy of treatment and interest in the presentation, and it is safe to say that such succinct biographies of the complete portrait gallery of our Presidents, written with such unquestioned ability, have never before been published."--_Hartford Courant._ "Just the sort of book that the American who wishes to fix in his mind the varying phases of his country's history as it is woven on the warp of the administrations will find most useful. Everything is presented in a clear-cut way, and no pleasanter excursions into history can be found than a study of 'The Presidents of the United States.'"--_Philadelphia Press._ =The United States of America.= _A Study of the American Commonwealth, its Natural Resources, People, Industries, Manufactures, Commerce, and its Work in Literature, Science, Education, and Self-Government._ Edited by NATHANIEL S. SHALER, S. D., PROFESSOR OF GEOLOGY IN HARVARD UNIVERSITY. =In two volumes, royal 8vo. Maps, and 150 full-page Illustrations. Cloth, $10.00.= Every subject in this comprehensive work is timely, because it is of immediate interest to every American. Special attention, however, may be called to the account of "American Productive Industry," by the Hon. Edward Atkinson, with its array of immensely informing diagrams and tables; and also to "Industry and Finance," a succinct and logical presentation of the subject by Professor F. W. Taussig, of Harvard University. Both these eminent authorities deal with questions which are uppermost to-day. LIST OF CONTRIBUTORS.
