The volume into which Valentine Chirol has collected and republished his valuable series of articles about the Indian unrest is an important and very instructive contribution to the study of what is probably the most arduous problem in the politics of the British Empire. His comprehensive survey of the whole situation, the arrangement of evidence and array of facts, are not unlike what might have been found in the Report of a Commission appointed to investigate the causes and the state of affairs to which the troubles that have arisen in India may be ascribed.
