and jackrabbit. At some distance from the main diggings a portion 

 of a mammoth tusk, together with some small splinters from split 

 bones and some pieces of charcoal, was found in the same horizon as 

 the other material. There were no implements or stone flakes in 

 association with the tusk, and as a consequence it cannot be stated 

 definitely that the creature was killed by the people who hunted the 

 bison and other animals. There was nothing to indicate that the 

 tusk and bone splinters were rolled or washed into the location where 

 they were found. The edges are sharp and show no marks of abrasion. 

 Evidence from other places has demonstrated that Folsom Man preyed 

 on the mammoth, and it is possible that the dwellers at the Linden- 

 meier camp did likewise. The tusk at least shows that mammoth were 

 in the vicinity at approximately the same time as the Folsom men, 

 an occurrence previously suspected but for which there was no proof. 

 One of the main objectives of the expedition, the recovery of a human 

 skeleton, was not attained. Thus far not one bone attributable to man 

 has come from the excavations, and the physical characteristics of the 

 people are still unknown. 



The sites visited in Nebraska are located in the southwestern corner 

 of the State in Chase and Dundy Counties. All those seen by the 

 writer are "blow-outs/' places where constant action by strong winds 

 has swept away areas of surface soil exposing the underlying stratum 

 of harder, claylike earth. The artifacts — points, scrapers, knives — 

 are found lying on these exposed surfaces. Folsom type points occur- 

 ring there are quite like those from the Lindenmeier site. In addition 

 there are numerous long, narrow, thick-bodied points with a triangular 

 or oval cross-section that have been given the name Yuma. The latter 

 are a complicating factor in that their meaning is not clear. They may 

 belong to the Folsom series or be an indication of another complex. 

 They are found in association with Folsom material in some localities, 

 but in others they are not. Only a very small percent of the points 

 from the Lindenmeier site can be regarded as having Yuma character- 

 istics, and the majority of these come from higher levels. Hence for 

 that district they can be regarded, at most, as demonstrating a very 

 late contemporaneity between the two forms. Information, from the 

 Nebraska sites contributes little toward answering the relationship 

 question because no digging was done. 



On the strength of information from D. B. Hilton, of Sundance, 

 Wyo., the writer went to that place to investigate the finding of two 

 Yuma type points and a series of five bison skulls. The discoveries 

 came as the result of work on an earth dam across Sundance Creek 

 just east of the town. The points were at the bottom of the soil zone
