not possess. I cannot take time here to go into details of this 

 investigation, but will state one or two of the general conclu- 

 sions to which the investigation led, and will show you some 

 views of the implements mentioned, which can be referred 

 with great reasonableness to the agency of the Nebraska man, 

 or perhaps to a race that preceded the Loess man of Nebraska. 



1. The Kansas artifacts are of at least three different and 

 successive dates. The earlier, more rude implements were 

 taken as a basis for the making of new implements. 



2. Th oldest artifacts were older than the Kansan glacial 

 epoch, and were the only ones that received this descriptive 

 term, Paleoliths. 



3. From the Paleolithic stage to the Early Neolithic, or 

 Mesolithic, was a profound break in all the characters, mark- 

 ing a transition to a higher type. 



4. This higher type continued through a long period, evi- 

 dently through several minor fluctuations that produced gla- 

 cial epochs. 



5. The latest or Neolithic culture was an imperceptible 

 outgrowth of the Early Neolithic. 



Since the conclusion of this work on the Kansas specimens, 

 partial examinations of stone artifacts from several other 

 states have led to similar conclusions, which, however, have 

 not been published.
