The CoZwnbia R i v e r !7'reaty by John V. Krutilla; 211 pages; $7.50; Resources for the Future, Inc., The John Hopkins Press, Baltimore, Md.; 1967.

In producing the Columbia River Treaty--the Economics of an International River Basin Developnent, Dr. Krutilla rather consciously focuses the reader's attention to the need and desirability of integrating the disciplines of engineering and re- sources economics to better serve the public in the developnent of a given hydro- logic basin upon which political boundaries have been superimposed.

each dealing with a time phase in the development sequence an international as well as inter- state river.

The work has been divided into three parts, on the Columbia River,

Part I, titled Developnt of International Rivers, covers the physiography of the Columbia River basin and the pre-treaty state of developnent. Part I1 covers the treaty study and negotiation period of 1960-61, the IJC principles established and the criteria of project selection and equitable benefits. Part I11 analyzes the second phase of negotiations from 1961-64, cost comparisons and summary and conclu- sions of treaty results.

and while sane pieces of useful information may not have been available to the author at the time of publication, it is doubtful that inclusion of such would have materially altered the conclusions reached. The application of the analytical work and criteria might apply to both international rivers subject to development treaty and to interstate systems whose development for equitable benefits requires a compact.

this category by identifying the basic issues involving both engineering and economics exclusive of the political ramifications which ultimately might be superimposed.

The work represents nearly nine years of research and analysis,

The work should serve a useful purpose in resource developnent on rivers in to be resolved and the basic analyses

that nust be made by the decision-makers,
