SIXTY-SIXTH ANNUAL REPORT 21 



University of Nebraska and in October accompanied a group from that 

 institution on a trip to Signal Butte in western Nebraska for the 

 purpose of reexamining the early sites at that location. On the basis 

 of information obtained during the course of his work, he prepared 

 a paper "Early and Late Lithic Horizons in the Plains'' which was 

 presented before the Sixth Conference for Plains Archeology at Lincolu 

 in November. Mr. Bhss left the Kiver Basin Surveys staff on 

 January 8. 



In addition to the field work previously mentioned, Paul L. Cooper 

 in September accompanied Dr. Waldo R. Wedel, Dr. Gordon Baldwin 

 of the National Park Service, and Dr. J. O. Brew and Frederick 

 Johnson of the Committee for the Recovery of Archeological Remains, 

 on an inspection trip to Missouri Basin archeological sites in Wyoming, 

 Montana, North Dakota, South Dakota, and Nebraska. Throughout 

 the remainder of the year his activities were centered in the laboratory 

 at Lincoln. Until March 24 he was in charge of the Lincoln head- 

 quarters during such times as Dr. Wedel was in Washington, but from 

 that date until June 30 devoted most of his attention to analyzing 

 the data and specimens obtained during the field season and in the 

 preparation of reports. He wrote a summary of the work done at two 

 reservoirs in South Dakota, ''Recent Investigations in Fort Randall 

 and Oahe Reservoirs, South Dakota,'' which was published in Amer- 

 ican Antiquity, vol. 14, No. 4, April 1949. 



Robert B. Cumming, Jr., archeologist, continued to plan and super- 

 vise the laboratory procedures, as mentioned in an earlier paragraph, 

 and from March 24 until June 30 was in charge of the Lincoln office 

 when Dr. Wedel was not present at the laboratory. 



Following the summer field work Jack T. Hughes, archeologist, 

 spent the remainder of the year in the laboratory studying the data 

 and materials collected from the various reservoirs he had examined 

 and writing reports on the results of his work. He prepared a 

 memorandum on Cheyenne Basin archeology for the National Park 

 Service and completed an article, ' 'Investigations in Western South 

 Dakota and Northeastern Wyoming," which was published in 

 American Antiquity, vol. 14, No. 4, April 1949. He collaborated 

 with Dr. Theodore E. White in writing a manuscript ''The Long Site, 

 an Ancient Camp in Southwestern South Dakota." The latter is a 

 prehminary account of the archeology and physiography of one of the 

 most significant sites yet found in the Angostura Reservoir basin. 

 Hughes also prepared a paper, "Archeology and Environment in the 

 Western Great Plains," which he presented at the Sixth Conference 

 for Plains Archeology held in Lincoln in November. In addition he 

 wrote a paper, "An Experiment in Relative Dating of Archeological 

 Remains by Stream Terraces," which he read before the Anthropology
