Marvin F. Kivett for the Nebraska State Historical Society as a part 

 of the Inter- Agency Archeological Salvage Program, gave a date of 

 660dzl50 years ago. Sample M-1080a^ charcoal from Feature 4 of 

 the Good Soldier site (39LM238) in the Big Bend Keservoir of South 

 Dakota, gave a date of 2,380±150 years ago. This sample was 

 excavated by Kobert W. Neuman of the Missouri Basin Project staff. 

 Sample M-1081^ charcoal from zone D of the Logan Creek site 

 (25BT3) in northeastern Nebraska, excavated by Marvin F. Kivett 

 for the Nebraska State Historical Society, gave a date of 7,250 ±300 

 years ago. Sample M-1082^ wood from a house post in a small long- 

 rectangular house (F. 2) of the Fay Tolton site (39ST11) in the 

 Oahe Eeservoir, gave a date of 860d=150 years ago. This sample was 

 excavated by Dr. Donald D. Hartle, then of the Missouri Basin Project 

 staff. An experiment in the decontamination of charcoal treated with 

 paraffin failed completely. A log, one end of which had been coated 

 with paraffin and the other end not so treated, had had the treated 

 end deparaffined and both sections were run for carbon- 14 analysis. 

 The two dates from the same piece of charred wood were several cen- 

 turies apart. 



The laboratory and office staff spent its full effort during the year 

 in processing specimen materials for study, photogTaphing and il- 

 lustrating specimens, preparing specimen records, and typing, filing, 

 and illustrating record and manuscript materials. Accomplishments 

 of the laboratory and office staff are listed in tables 1 and 2. 



The Missouri Basin Project staff archeologists and archeologists 

 of the National Park Service and cooperating States agencies working 

 in the Missouri Basin met on July 30 in a roundtable field conference 

 in Pierre, S. Dak. This lYi/^th Plains Conference, now a regular 

 summer event, and a supplement to the annual Thanksgiving Plains 

 Conference, was devoted to discussions of current fieldwork and 

 technical problems of field identifications. During the Thanksgiving 

 weekend, members of the staff participated in the 18th Plains Confer- 

 ence for Archeology, held in Norman, Okla. On April 14, members 

 of the staff participated in the seventy-first annual meeting of the 

 Nebraska Academy of Sciences in Lincoln. 



Dr. Robert L. Stephenson, Chief, devoted a large part of his time 

 during the year to managing the office and laboratory in Lincoln and 

 preparing plans and budgets for the 1961 field season. He compiled 

 a 7- volume summary of construction data and archeological work in 

 all the 789 named reservoir sites in the Missouri Basin for use in fu- 

 ture planning in the Lincoln office. He completed the revision of a 

 large technical monograph, "The Accokeek Creek Site: A Middle 

 Atlantic Seaboard Culture Sequence," previously accepted as his doc- 

 toral dissertation at the University of Michigan, and continued with 

 preliminary analysis of materials he recovered from the excavations
