the materials recovered during the digging. Eecommendations were 

 made pertaining to the continuance of the investigations and improve- 

 ments in the handling and cataloging of specimens. 



In November Dr. Koberts went to Norman, Okla., to attend the 

 Plains Conference for Archeology and participate in discussions re- 

 lating to the history of the Indians in that general area. 



Early in April at Mule Creek, Wyo., Dr. Roberts made arrange- 

 ments for establishing a camp and starting a series of excavations in a 

 Paleo-Indian site — a cooperative project between the National Geo- 

 graphic Society and the Smithsonian Institution. Upon the comple- 

 tion of these activities he proceeded to Lawton, Okla., where he was 

 the principal speaker at the dedication of the Museum for the Great 

 Plains on April 9. Returning to the Washington office, he began 

 preparations for sending a field party to the site at Mule Creek and 

 in that connection left Washington early in Jmie for Lincoln, Nebr., 

 where he was joined by Dr. William M. Bass, who was to be the chief 

 field assistant, and several other members of the party. They picked 

 up two vehicles and field equipment and proceeded to Mule Creek to 

 set up camp, and on June 12 began excavations. Dr. Roberts re- 

 mained with the party until June 19. The party, however, continued 

 operations under Dr. Bass and was busy digging at the end of the fis- 

 cal year. As a result of the work up to that time an extensive deposit 

 of bison bones, probably representing an extinct species, and a number 

 of artifacts have been recovered. The site is one that dates about 

 9,000 years ago. 



Dr. Roberts completed a manuscript, "The Agate Basin Complex," 

 which is to be published in Mexico in a volume containing articles 

 about the Paleo-Indian. He also did the technical editing of a 

 series of seven reports on archeological excavations and studies in 

 three reservoir areas, to appear in Bulletin 185 of the Bureau of 

 American Etlmology. 



At the beginning of the fiscal year, Dr. Henry B. Collins, anthro- 

 pologist, was in Europe studying collections in the principal museums 

 and attending two international anthropological congresses. He 

 visited Lascaux and a number of other Paleolithic cave and rock shel- 

 ter sites in the Dordogne region of France and examined Megalithic 

 sites and monmnents in the Morbihan and Finistere districts of Brit- 

 tany. Dr. Collins attended the 34th International Congress of Ameri- 

 canists in Vienna, July 18-25, and the 6th International Congress of 

 Anthropological and Ethnological Sciences in Paris, July 30- 

 August 6. At the latter he presented a paper discussing the present 

 status of evidence bearing on the origin of Eskimo culture. 



Dr. Collins continued to participate in the activities of the Arctic 

 Institute of North Amercia as a member of its Board of Governors, 

 as a member of the Publications Committee that supervises prepara-
