This is a clear and thorough history of arbitration with an explanation of the current state of conciliation with some generally pacificist overtones and a desire to make practical the implementation of peaceful arbitration as opposed to armed combat for settling international disputes. The pamphlet provides a very clear, thoughtful, interesting and prescient inter-war reaction to conflict. Appendices include a list of books for further reading, Article 10 of the Geneva Protocol, 1924 and Article 36 of the Statues of the Permanent Court for International Justice.
