in Pierre, S. Dak. This 16%th Plains Conference, now a regular sum- 

 mer event, and an adjunct of the annual autumnal Plains Conferences, 

 was devoted to discussions of basic technical problems arising from 

 current field activities. They centered principally around the se- 

 quences of cultural groupings in this area and the interrelationships 

 between the several cultural manifestations represented by excavated 

 materials. During the Thanksgiving weekend, members of the staff 

 participated in the 17th Plains Conference for Archeology, held in 

 Lincoln. On April 23, members of the staff took part in the Seven- 

 tieth Annual Meeting of the N'ebraska Academy of Sciences, held also 

 in Lincoln. 



Dr. Robert L. Stephenson, chief, devoted considerable time to 

 managing the office and laboratory in Lincoln and preparing plans 

 and budgets for the 1960 field season. He also worked on a summary 

 report of the Missouri Basin Salvage Program for the calendar years 

 1952-60, and on a complete revision of a large technical monograph, 

 "The Accokeek Creek Site : A Middle Atlantic Seaboard Culture Se- 

 quence," previously accepted as his doctoral dissertation at the Uni- 

 versity of Michigan. He began preparation of an article, "Adminis- 

 tration in Anthropology," and started preliminary analysis of the 

 materials he recovered from the excavations at the Sully site (39SL4) 

 in the Oahe Eeservoir in 1956 to 1958. He also continued writing on 

 the manuscript reporting the "Archeological Investigations in the 

 Whitney Reservoir, Texas." Throughout the year he served as chair- 

 man of the Missouri Basin Chronology Program. In July he served

 and during the Thanksgiving weekend served as general chairman for 

 the 17th Plains Conference held in Lincoln, Nebr. He was a panel dis-

 for the Recovery of Archeological Remains, held in Washington, D.C., 

 and on April 23, he attended the Seventieth Annual Meeting of the

 Ceramic Dichotomy" which was published in abstract in the Proceed-
