These lectures were delivered at the London School of Economics in May of the present year. They are largely based on experience gained in the work of the Percy Sladen Trust Expedition to Melanesia of 1908, and give a simplified record of social conditions which will be described in detail in the full account of the work of that expedition. A few small additions and modifications have been made since the lectures were given, some of these being due to suggestions made by Professor Westermarck and Dr. Malinowski in the discussions which followed the lectures. I am also indebted to Miss B. Freire-Marreco for allowing me to refer to unpublished material collected during her recent work among the Pueblo Indians of North America. W. H. R. Rivers.
