SECRETARY’S REPORT 75 
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 Lincoln 
in November. Mr. Bliss left the River 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 
preliminary 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
