being so much as two inches in length, and varying from that size to 

 not more than half an inch. Nearly all 

 are very thin, though some of the nar- 

 rower ones may have a diamond or thick 

 lenticular section. Some are very slender, 

 so much so that they are usually classed 

 as perforators; others are equilateral. 

 Both the base and edges may be straight, 

 convex, or concave. A few have a shallow 

 notch in each edge just above the corner; 

 nearly all, however, have both base and

The groups and subdivisions which have been recognized among the 

 smaller chipped flint objects in the Bureau collection may be enumerated 

 as follows: 



A. Concave base. The concavity may vary from almost a straight 

 line to one-third the length of the flint. Usually symmetric, as in 

 figures 190 and 191, though sometimes one tang or barb, if it may be 

 called such, is longer than the other, as in figure 192. A very few 

 have beveled or serrated edges. 



1. Convex edges. The type, shown 

 in figure 190, is from Jefferson county, 

 Tennessee. Other specimens are 

 from eastern Tennessee ; Union county, 

 Mississippi; northwestern Georgia, 

 and Bibb county and Savannah in the 

 same state ; central and western North 

 Carolina; Miami and Scioto valleys 

 and central Ohio; Kanawha valley^

southwestern Arkansas. 

 2. Straight edges, as in the specimen illustrated in figure 191, from 

 Ouachita county, Arkansas. Similar specimens are found in north- 

 eastern and southwestern Arkansas; western and central North Caro- 

 lina; Kanawha valley ; eastern Wisconsin ; northwestern Georgia, and 

 Savannah; eastern Tennessee; South Carolina; south- 

 western Illinois; Union county, Mississippi; and north- 

 eastern Kentucky. 



3. Concave edges. This abundant form is illustrated 

 in figures 192 (Cherokee county, Georgia), 193 (Caldwell 

 connty, North Carolina), and 194 (Washington county, 

 Virginia). Other specimens are from northwestern 

 Georgia and Savannah; central and western North 

 Carolina; Kanawha valley; eastern Tennessee; northeastern Ken- 

 tucky; southwestern Arkansas ; South Carolina; Union county, Miss- 

 issippi; and Coosa valley, Alabama. This subdivision of group A is 

 abundant, as well as widely distributed.
