All forms are stemless and notchless, essentially triangular in out- 

 line, and have modifications in the specifications of basal and side 

 edges. In overall length they range from 40 mm. to 17 mm., with 

 thickness an ungoverned variable. 



Type 1. Straight base and straight sides. The ratio of the one to the 

 other determines both the length of the blade and the gen- 

 eral width of the point. 

 Type 2. Straight base and concave sides. 

 Type 3. Straight base and convex sides. 

 Type 4. Straight base and serrate straight sides. 

 Type 5. Straight base and serrate concave sides. 

 Type 6. Straight base and serrate convex sides. 

 Type 7. Straight base with one edge longer than the other. 

 Type 8. Concave base and concave sides. 



Subtype 8a. Concave base with sharply pointed barbs joined by 



concave sides. 

 Subtype 8b. Concave base with rounded barbs joined by concave 

 sides. 

 Type 9. Concave base and serrate concave sides. 



Subtype 9a. Concave base with sharply pointed barbs joined by 



serrated concave sides. 

 Subtype 9b. Concave base with rounded barbs joined by serrated 

 concave sides. 

 Type 10. Concave base with convex sides. 

 Type 11. Concave base with straight sides. 

 Type 12. Convex base with convex sides. 

 Type 13. Convex base with serrated convex sides. 

 Type 14. Convex base with concave sides. 

 Type 15. Embraces all asymmetrically sided forms. 



This classification is offered as an aid for convenience of description 

 in general terms, since there is much overlapping in form from one 

 to the other, so it must be accepted as is unless greater divisions are 

 to be made stressing every slight difference in form that is bound to 

 occur. 



Distribution is rather widespread throughout the East and South- 

 east wherever Late Woodland or Mississippian influences have been 

 felt. 



DISCUSSION 



The chippcd-stone artifacts in the John H. Kerr Reservoir Basin 

 present a gradient from some of the Paleo- American forms (or Early 

 Hunter) to the Late Woodland types, reflecting not only all degrees 

 of skill in the various chipping techniques but also in style and vari- 

 ation of form as well. This is best exemplified in projectile types, 

 scraper forms, burins, knives, choppers, and hand axes. Symmetry 

 and asymmetry of form may have been both deliberate and accidental. 

 Under the deliberate, can be listed, offhand, such forms as types 1 

 and 2 of the Sandia, Manzano, Pinto Basin, and Lake Mohave. Gen- 

 erally considered as accidental are such forms attributed to cutting
