IN this important series of talks the Professor of International Relations in the University of London has described, from an exceptional expert knowledge, the workings of the diplomatic machine by which the relations between countries are manipulated, and especially the comparatively new instrument, the League of Nations. He now concludes his series by discussing the outlook for the future, and listeners who have heard his previous talks will await with interest his summing-up, especially now that on so many sides are heard the Jeremiahs predicting the date of the next world war.
