I made this study as a fellow of the Social Science Research Council and I wish to acknowledge my great indebtedness to the generosity of the Board of Fellowships of that body. For the training which prepared me to undertake this inquiry I have to thank Professor Franz Boas and Dr. Ruth F. Benedict. I owe a debt of gratitude to Professor A. R. Radcliffe-Brown of the University of Sydney who most kindly sponsored my field trip with the Australian research and governmental interests and also gave me much advice and help.
I have to thank my husband, Reo Fortune, for assistance in the formulation of my problem, for long months of co-operative effort in the field, for much of the ethnographic and textual material which underlies this study and for patient criticism of my results.
I am indebted to the Department of Home and Territories of the Commonwealth of Australia and to the Administration of the Mandated Territory of New Guinea for furthering my research whenever possible; most particularly I have to thank His Honour Judge J. M. Phillips and Mr. E. P. W. Chinnery, Government Anthropologist.
