This personal biography of Marx, by an intimate friend who was himself one of the foremost Socialists of Germany, gives a new insight into the beginnings of Socialism. Moreover, it is a charming book, as interesting as a novel, and will make an admirable introduction to heavier reading on Socialism. 2. +Collectivism and Industrial Evolution.+ By Emile Vandervelde, member of the Chamber of Deputies, Belgium. Translated by Charles H. Kerr. Cloth, 50 cents. The author is a Socialist member of the Belgian Parliament and is one of the ablest writers in the international Socialist movement. This book is, on the whole, the most satisfactory brief summary of the principles of Socialism that has yet been written. One distinctive feature of it is that it takes up the difficult questions of how the machinery of production could be acquired and how wages could be adjusted under a Socialist administration. 3. +The American Farmer: An Economic and Historical Study.+ By A. M. Simons. Cloth, 50 cents. "The American Farmer," in spite of its small size, is the largest contribution yet given to the agrarian literature of this country. The author, besides being a student of American social conditions, is thoroughly conversant with practical farming, and there is little doubt that the farmer who reads the work will have to admit that the conclusions are based on a real understanding of the difficulties of his struggle with the soil, with railroads, trusts and foreign competitors.--Chicago Tribune. 4. +The Last Days of the Ruskin Co-operative Association.+ By Isaac Broome. Cloth, illustrated, 50 cents. Socialism does not mean withdrawing from the class struggle and trying to set up a paradise on a small scale. If there are those who still think such a scheme practicable, they will find interesting facts in this book. 5. +The Origin of the Family, Private Property and the State.+ By Frederick Engels. Translated by Ernest Untermann. Cloth, 50 cents. This is one of the most important of the author's works, and although first published in 1884, was never accessible to English readers until our translation appeared in 1902. It contains practically everything necessary to the general reader in the voluminous work of Morgan, and it furthermore gives many additional facts and a coherent, scientific treatment of the whole subject. The book is of great propaganda value, in that it shows the folly of the popular idea that wealth and poverty always have existed and so may always be expected to continue. 6. +The Social Revolution.+ By Karl Kautsky. Translated by A. M. and May Wood Simons. Cloth, 50 cents.
