SIXTIETH ANNUAL REPORT S 



for the purpose of making comparisons with other South American 

 languages and with a vicAv to discerning possible further linguistic 

 affiliations. In addition to this work, Dr. Harrington has also made 

 an extensive study of the grammar of the Jivaro language of South 

 America. 



At the beginning of the fiscal year Dr. Frank H. H. Koberts, Jr., 

 senior archeologist, was engaged in prospecting and testing an in- 

 teresting site in the Agate Basin, on a tributary of the Cheyenne 

 River between Lusk and Newcastle, in eastern Wyoming. Dr. Roberts 

 had been sent to make preliminary investigations at this location, 

 despite the general policy of no regular field work for the duration 

 of the war, because of the possibility that much information might 

 be lost as a result of erosive activities in the area and from disturb- 

 ance of the deposits by amateur collectors hunting for specimens. 

 The site gave evidence of having been the scene of a bison kill on the 

 edges of a marsh or meadow. Animal bones and artifacts were found 

 in a stratum that breaks out of the bank some 20 feet above the bottom 

 of an eroding gully. This layer is covered by an overburden that 

 deepens rapidly as it is followed back into the bank, and at a depth 

 of 4 feet, where the tests were terminated, was still continuing. All 

 the bones found, of which there w^ere many, proved to be modern 

 bison. Associated with these were projectile points, which, although 

 they suggest an affinity with the Collateral Yuma type — a form that 

 has been considered relatively early in the Plains area — nevertheless do 

 not have all the significant characteristics of that type. The points 

 have unhesitatingly been called Yuma by numerous people who 

 have examined them, and there is no question of their belonging 

 in that general category, although they should not be considered 

 classic forms. All the points found at the site are consistent in 

 pattern, yet have a considerable range in size. In the seventy- 

 some points or large and easily identified fragments found there, 

 no shouldered, barbed, or tanged forms appear. The material un- 

 questionably represents a cultural unit without intrusions from 

 other sources. Dr. Roberts dug 32 examples out of undisturbed 

 deposits. The remaining specimens are in the collections of local 

 residents, who picked them up as they weathered out of the gully 

 bank. Only a few end and side scrapers have been found, prob- 

 ably because of the fact that the camp proper has not yet been 

 located, but they are typical of those associated with the so-called 

 early hunting complexes. Geologic studies have not yet been made 

 of the deposits. They indicate some antiquity, but that they are 

 not as old as the age formerly postulated for Yuma remains is demon- 

 strated by the fact that the bison represented are all modern forms. 

 It is hoped that when present conditions are over, the site can be
