Book excerpt: “Mann’s book is timely, and its central theme, the role of legal, political, and scientific institutions in the utilization of water in Arizona, is appropriate. It is appropriate, moreover, for the greater region of California and the Southwest, where exist similar problems. . . . The Politics of Water in Arizona ranks along with Richard Cooley’s prize winning Politics and Conservation: The Decline of the Alaska Salmon as an outstanding contribution of a political science to the field of conservation and resource utilization.”—California Historical Society Quarterly
