THE ICE AGE IN NORTH AMERICA, and its Bearings upon the Antiquity of Man. By G. FREDERICK WRIGHT, D. D., LL. D., F. G. S. A., Professor in Oberlin Theological Seminary; Assistant on the United States Geological Survey. With an appendix on "The Probable Cause of Glaciation," by WARREN UPHAM, F. G. S. A., Assistant on the Geological Surveys of New Hampshire, Minnesota, and the United States. New and enlarged edition. With 150 Maps and Illustrations. 8vo, 625 pages, and Index. Cloth, $5.00.

"Not a novel in all the list of this year's publications has in it any pages of more thrilling interest than can be found in this book by Professor Wright. There is nothing pedantic in the narrative, and the most serious themes and startling discoveries are treated with such charming naturalness and simplicity that boys and girls, as well as their seniors, will be attracted to the story, and find it difficult to lay it aside."—New York Journal of Commerce.

"One of the most absorbing and interesting of all the recent issues in the department of popular science."—Chicago Herald.

"Though his subject is a very deep one, his style is so very unaffected and perspicuous that even the unscientific reader can peruse it with intelligence and profit. In reading such a book we are led almost to wonder that so much that is scientific can be put in language so comparatively simple."—New York Observer.

"The author has seen with his own eyes the most important phenomena of the Ice age on this continent from Maine to Alaska. In the work itself, elementary description is combined with a broad, scientific, and philosophic method, without abandoning for a moment the purely scientific character. Professor Wright has contrived to give the whole a philosophical direction which lends interest and inspiration to it, and which in the chapters on Man and the Glacial Period rises to something like dramatic intensity."—The Independent.

"... To the great advance that has been made in late years in the accuracy and cheapness of processes of photographic reproduction is due a further signal advantage that Dr. Wright's work possesses over his predecessors'. He has thus been able to illustrate most of the natural phenomena to which he refers by views taken in the field, many of which have been generously loaned by the United States Geological Survey, in some cases from unpublished material; and he has admirably supplemented them by numerous maps and diagrams."—The Nation.

MAN AND THE GLACIAL PERIOD. By G. FREDERICK WRIGHT, D. D., LL. D., author of "The Ice Age in North America," "Logic of Christian Evidences," etc. International Scientific Series. With numerous Illustrations. 12mo. Cloth, $1.75.

"It may be described in a word as the best summary of scientific conclusions concerning the question of man's antiquity as affected by his known relations to geological time."—Philadelphia Press.

"The earlier chapters describing glacial action, and the traces of it in North America—especially the defining of its limits, such as the terminal moraine of the great movement itself—are of great interest and value. The maps and diagrams are of much assistance in enabling the reader to grasp the vast extent of the movement."—London Spectator.

HISTORY OF THE PEOPLE OF THE UNITED STATES, from the Revolution to the Civil War. By JOHN BACH McMASTER. To be completed in six volumes. Vols. I, II, III, and IV now ready. 8vo, cloth, gilt top, $2.50 each.

In the course of this narrative much is written of wars, conspiracies, and rebellions; of Presidents, of Congresses, of embassies, of treaties, of the ambition of political leaders, and of the rise of great parties in the nation. Yet the history of the people is the chief theme. At every stage of the splendid progress which separates the America of Washington and Adams from the America in which we live, it has been the author's purpose to describe the dress, the occupations, the amusements, the literary canons of the times; to note the changes of manners and morals; to trace the growth of that humane spirit which abolished punishment for debt, and reformed the discipline of prisons and of jails; to recount the manifold improvements which, in a thousand ways, have multiplied the conveniences of life and ministered to the happiness of our race; to describe the rise and progress of that long series of mechanical inventions and discoveries which is now the admiration of the world, and our just pride and boast; to tell how, under the benign influence of liberty and peace, there sprang up, in the course of a single century, a prosperity unparalleled in the annals of human affairs.

"The pledge given by Mr. McMaster, that 'the history of the people shall be the chief theme,' is punctiliously and satisfactorily fulfilled. He carries out his promise in a complete, vivid, and delightful way. We should add that the literary execution of the work is worthy of the indefatigable industry and unceasing vigilance with which the stores of historical material have been accumulated, weighed, and sifted. The cardinal qualities of style, lucidity, animation, and energy, are everywhere present. Seldom indeed has a book in which matter of substantial value has been so happily united to attractiveness of form been offered by an American author to his fellow-citizens."—New York Sun.

"To recount the marvelous progress of the American people, to describe their life, their literature, their occupations, their amusements, is Mr. McMaster's object. His theme is an important one, and we congratulate him on his success. It has rarely been our province to notice a book with so many excellences and so few defects."—New York Herald.

"Mr. McMaster at once shows his grasp of the various themes and his special capacity as a historian of the people. His aim is high, but he hits the mark."—New York Journal of Commerce.

"... The author's pages abound, too, with illustrations of the best kind of historical work, that of unearthing hidden sources of information and employing them, not after the modern style of historical writing, in a mere report, but with the true artistic method, in a well-digested narrative.... If Mr. McMaster finishes his work in the spirit and with the thoroughness and skill with which it has begun, it will take its place among the classics of American literature."—Christian Union.
