Plate 31. 
This plate illustrates a form of a chipped implement which 
appears to have been used interchangeably as a dart point 
or as a knife. It has been called Da/ton or Dalton Point 
after the late Judge S. P. Dalton, former Chief Justice of 
the Missouri Supreme Court, who discovered and described 
the type site near Jefferson City, Missouri. It is sometimes 
called Da/ton Serrated, because of the serrations on the 
blade edges of many specimens. Plate 31E illustrates a 
typical example. Blades were resharpened by a beveling 
technique, which modern experiments have shown to be 
the best way to get maximum use. With the point up, the 
bevel usually slopes to the right, although there are occas- 
ional exceptions. Plate 31A is an example of such an ex- 
ception. All of the points illustrated in the top row of 
Plate 31, that is, A, B, C and D have been sharpened very 
little. The three illustrated in the bottom row (E, F, and G) 
have been sharpened so often that they can now serve 
best as drills or reamers. 
Dalton Points are most numerous in the central part of the 
Mississippi Valley. Similar forms bearing different names 
such as Meserve, Greenbrier and Hardaway are found to 
the west, south and east. 
Chapman (1975, p. 245) points out that Dalton Serrated 
has been found jn situ in the earliest levels of Graham 
Cave, Arnold Research Cave and Rogers Shelter in Missouri. 
Radiocarbon dates range from about 8500 to 6000 B.C., 
but use of this form may have persisted to as recent as 
5000 B.C. in some places. Daltons appear to represent a 
transition from the lanceolate, Clovis and Folsom points of 
the early Paleo-Indian hunters to the notched and stemmed 
forms of the later Archaic hunters and gatherers.
