_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,

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
