Savannah, Georgia. 



U. Difl'ering from specimen 

 shown in figure 203, in having 

 the edges expand at the shoul- 

 ders iu a projection or point, 

 and varying more iu size, some 

 being small enough for arrow- 

 heads. All from Savannah 

 (including the example shown 

 in figure 205) are of smoother 

 finish than those from other 

 sections, and are usually 

 larger, ranging from 2^ to 4J

 ity with base straight or convex. Found also in western and central 

 North Carolina; Kanawha valley; South Carolina; eastern Tennessee; 

 Coosa valley and northeastern Alabama; Brown county, Illinois; north- 

 eastern, southeastern, and southwestern Arkansas; and southwestern 

 Georgia. 



F. Edge having a double curve, being convex toward the point, and 

 curving outward at the shoulders. Few of them are barbed, though 

 many have the shoulder much expanded. Base some- 

 times convex or concave, but more often straight; iu a 

 few it is somewhat pointed. In most of the smaller 

 specimens the base is notched, but of 

 these none are over 2h inches long. Stem 

 tapering or expanding, rarely straight. 

 A few have the base rubbed smooth and f^' 

 dull, or even polished (this feature ap- V 

 pears in other forms, as noted); it seems \, 

 to result from use as a knife or scraper, 

 but the implement as a whole does not 

 apijear to be adapted to such use. None 

 of them are over 3J inches long, except 

 fliLt d°ouWecu''rved a few from Savanuah ; all from there are 



e<ig«*- wide, but from other places the longer ion 



ones are all narrow. 



The specimens illustrated (figures 206 and 207) are from Madison 

 county, Alabama, and Kanawha valley, respectively. Others are from 

 northeastern Alabama and Coosa valley; eastern Tennessee; north- 

 western and southwestern Georgia and Savanuah; Kanawha valley ; 

 Catahoula parish, Louisiana; western and central North Carolina; 

 southwestern Illinois and Brown county in the same state; South 

 Carolina; southwestern Arkansas; and Miami valley, Ohio. 



G. Convex edges; sharp points; stem always long and tapering; 

 base somewhat pointed, or outline of whole stem forming a regular
