The author of this scholarly survey, one of a handful of Korean specialists, died in 1948; the manuscript was completed by his wife and Mr. Grey. The learning and insight which mark this book make it particularly valuable today when there is so little information on that unhappy and relatively unknown land. The principal flaw in the study is that lacking first hand or reliable information on North Korea the author felt obliged to rely (with the inevitable distorting effects) on the official handouts from that area and from Soviet sources.
