Chicago Conference on Trusts. Speeches, Debates, Resolutions, List of the Delegates, Committees, etc. Held September 13-16, 1899. Chicago : The Civic Federation of Chicago, 1900. These 626 pages contain very few facts, and fewer arguments, that were not previously familiar to everyone who had followed either academic or popular discussions of capitalistic tendencies. While the book cannot therefore be said to have added to known facts about trusts, it certainly does constitute a very valuable exhibit of the ways in which different types of our people are today thinking about them.

For this reason the book will soon be ancient history, but at the present moment it is well worth the atten- tion of all who are concerned with our social and political problems.

The idea which the book develops is that there is demand for a science of political power to be placed by the side of economic sci- ence (1). Compared with economic, scientific, aesthetic, or religious
