In October a Missouri Basin Project team composed of J. J. Hoff- 

 man and Lee G. Madison joined Dr. Paul Sears of Yale University, 

 Dr. J. G. Ogden of Ohio Wesleyan University, and Dr. Harry A. 

 Tourtelot of the U.S. Geological Survey in a trip to collect fossil pollen 

 cores in the sandhills of northwestern Nebraska. The field trip was 

 a part of the chronology program and a part of a continuing program 

 of palynology designed to reconstruct prehistoric floral conditions 

 for a portion of the Missouri Basin. Cores were collected at several 

 of the fossil lakes in the area and will be analyzed by Dr. Ogden. 



Other chronology studies included a continuation of the dendro- 

 chronology section under the direction of Dr. Warren W. Caldwell, 

 with the volunteer assistance of Harry E. Weakly. The carbon-14 

 section continued to progress with the addition of 16 new dated 

 samples of vegetal material, tested by the laboratory of Isotopes, Inc., 

 of Westwood, N.J. Robert W. Neuman continued to be in charge 

 of this section of the program and submitted several samples for 

 dating to the new carbon-14: laboratory at the Smithsonian Institution 

 in Washington, D.C. In addition, two samples were sent to the Uni- 

 versity of Tesas for analysis in its carbon-14 laboratory. 



The laboratory and office staff of the Missouri Basin Project devoted 

 most of its full effort during the year to processing specimen materials 

 for study, photographing and illustrating specimens, preparing speci- 

 men records, and typing, filing, and illustrating record and manuscript 

 materials. The accomplishments of the laboratory and office staff are 

 listed in tables 1 and 2. 



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

 during the year to management of the overall Missouri Basin Project, 

 including the office and laboratory in Lincoln, the several field activi- 

 ties, and the preparation of plans and budgets. His individual arche- 

 ological research and report writing was minimal during the year, 

 but some further progress w^as made on the monograph "The Whitney 

 Reservoir, Texas" and on analyses of specimens from his excavations 

 at the Sully site (39SL4) in the Oahe Reservoir. He made final 

 revisions on his manuscript "The Accokeek Creek Site : A Middle At- 

 lantic Seaboard Culture Sequence" and submitted it to the University 

 of Michigan for publication. He also revised a paper he read at the 

 1962 meeting of the Society for American Archeology, entitled "Ad- 

 ministrative Problems of the River Basin Surveys," for publication in 

 American Antiquity. He continued to serve as chairman of the Mis- 

 souri Basin Chronology Program; as assistant editor of "Current 

 Research" in the Plains Area for American Antiquity; and, until 

 December 1, as associate editor of the Plaitis Anthropologist. On 

 December 1 he became editor of that journal. He also participated in
