IN April 1939 I received a fellowship from the Australian National Research Council to carry out nine months' field work among the Abelam tribe in the Sepik district of New Guinea. Since the village had its regular seasonal activities, I decided to remain another three months in order to make my work as complete as possible. I should like to take this opportunity to thank the Council and its officers for the assistance I received ; I am particularly indebted to Professor A. P. Elkin, Chairman of the Committee on Anthropology, for the help and encouragement which he has always extended to me in the course of my research. The area was suggested to me by Dr. Margaret Mead, who had studied the Arapesh on its northern boundary, and by Mr. Gregory Bateson, who had worked with the Iatmul, to the south-east on the Sepik River. With both these tribes the Abelam have cultural affinities, and my material therefore represents a further contribution to our knowledge of that district. To Dr. Mead and Mr. Bateson, I owe much for their helpful advice and the use of manuscripts, which suggested new avenues of approach while I was in the field. My work was made much easier by the ready co-operation and hospitality afforded me by members of the Administration, among whom I would like to mention His Honour Judge Phillips in Rabaul, Mr. G. Townsend, then District Officer at Wewak, and Messrs. K. Bridge, T. Ellis, J. Grant and I. Wood at Maprik. I am grateful for the many kindnesses I received from residents in the district Mr. and Mrs. W. Royal, Mr. and Mrs. Broadbent, Sister Stock, and Messrs. McKechnie, Curtin, Parer, Cecil, and Macgregor. I should like to thank Dr. H. Spencer-Roberts, then Medical Officer at Wewak, for the chance to visit many villages on the Sepik.
