because information recorded on tape for later transcription at the 

 Museum was accomplished in collaboration with the collectors, 

 Captain and Mrs. A. W. F. Fuller, Curator Force continued his 

 research interests that bear on the social organization, political 

 change, and native bead-money of the Palau Islands in Micronesia 

 (see Annual Report 1956, page 40). The first of several projected 

 manuscripts based on field work conducted in the Palaus from 1954 

 to 1956 was completed. 



Dr. Donald Collier, Curator of South American Archaeology and 

 Ethnology, worked on the analysis of data and collections gathered 

 in 1956 during the archaeological expedition to Peru. A radiocarbon 

 date of 342 B.C. ±80 years was obtained from the Lamont Geological 

 Observatory of Columbia University on a sample from a wooden 

 lintel in the hilltop fortress of Chanquillo in Casma Valley. This 

 places the stone fortifications in Casma in the same period as the 

 hilltop redoubts in Viru Valley to the north, which were studied in 

 1946 by the expedition to Peru. He continued to collaborate with 

 Dr. A. L. Kroeber, Research Associate in American Archaeology, in 

 preparation of a report on the Nazca culture of the south coast of 

 Peru. Throughout the year he carried out research on Mexican 

 archaeology in connection with reinstallation of Hall 8 (Ancient and 

 Modern Indians of Mexico and Central America). 



During the first part of the year Assistant Curator Rinaldo 

 collaborated with Chief Curator Martin in preparation of a report 

 on the excavations made during the summer of 1957. For his part 

 in this report Dr. Rinaldo made an analysis that indicates that the 

 source of some of the materials recovered might be assigned to the 

 Concho Complex, a specialized manifestation of the more widespread 

 Desert Culture (beginning of which is placed at about 9000 B.C.), 

 whereas the tools and accessories of the later cultures possessed 

 attributes of both those found in the Anasazi culture, located to the 

 north, and the Mogollon culture to the south. 



Phillip H. Lewis, Assistant Curator of Primitive Art, continued 

 to develop the Division of Primitive Art in both its research and 

 exhibition. In research the emphasis continued upon gathering 

 factual information about the distribution, variation, meaning, and 

 function of the art of primitive societies. Study of the Museum's 

 Melanesian collections, particularly those from New Ireland, and of 

 the African collections continued. 



Led by Allen S. Liss, Custodian of Collections, and Dr. Elaine 

 Bluhm, of the University of Illinois, excavation of the Anker site in 

 south Cook County was carried on in co-operation with the Illinois 

 Archaeological Survey as a joint project of this Museum and the
