Kautsky is the editor of the Neue Zeit, and is universally recognized as one of the ablest Socialist writers and thinkers in Europe. This book is in two parts. Part I., Reform and Revolution, explains the essential difference between the Socialist party and all reform parties. Part II., The Day After the Revolution, gives straightforward answers to the questions so often asked about what the Socialists would do if entrusted with the powers of government. 7. +Socialism, Utopian and Scientific.+ By Frederick Engels. Translated by Edward Aveling, D.Sc., with a Special Introduction by the Author. Cloth, 50 cents. This book ranks next to the Communist Manifesto as one of the best short statements in any language of the fundamental principles of Socialism. It is an essential part of every Socialist library, however small. 8. +Feuerbach: The Roots of the Socialist Philosophy.+ By Frederick Engels. Translated, with Critical Introduction, by Austin Lewis. Cloth, 50 cents. This book is a criticism on the works of a forgotten philosopher, but it is still of timely interest, since attempts are still being made to reintroduce dualist notions into the philosophy of Socialism. Austin Lewis contributes an interesting historical introduction. 9. +American Pauperism and the Abolition of Poverty.+ By Isador Ladoff, with a supplement, "Jesus or Mammon," by J. Felix. Cloth, 50 cents. A study of the last United States census, bringing out in bold relief the social contrasts that are purposely left obscure in the official documents. An arsenal of facts for Socialist writers and speakers. 10. +Britain for the British (America for the Americans.)+ By Robert Blatchford, with American Appendix by A. M. Simons. Cloth, 50 cents. A popular presentation of Socialism, in the same charming and simple style as the author's "Merrie England," but giving a far more adequate and scientific account of the subject. 11. +Manifesto of the Communist Party.+ By Karl Marx and Frederick Engels. Authorized English Translation: Edited and Annotated by Frederick Engels. Also included in the same volume, +No Compromise: No Political Trading.+ By Wilhelm Liebknecht. Translated by A. M. Simons and Marcus Hitch. Cloth, 50 cents. This manifesto, first published in 1848, is still recognized the world over as the clearest statement of the principles of the international Socialist party. It has been translated into the language of every country where capitalism exists, and it is being circulated more rapidly to-day than ever before. 12. +The Positive School of Criminology.+ By Enrico Ferri. Translated by Ernest Untermann. Cloth, 50 cents.
