 Handles. — Types. 



Differentiated by 



1. Number. 



2. Position on the vessel. 



(A) Body. 



(B) Neck. 



(C) Foot. 



(D) Combinations.

ABTICIiES IN STONE 



Chipped stone 

 I. Knives and projectile points. 



Larger ^5 cm. (2 inches) or more in length. 

 Smaller = less than 5 cm. (2 inches) in length. 

 Types. 



1. Without stem. 



( A ) Without secondary chipping ( =:flakes ) . 



(B) With secondary chipping. 

 (a) Pointed. 



{a') At one end. 

 Base concave. 

 Base straight. 

 Base convex. 

 Sides convex. 

 One side convex. 

 One side straight. 



(6') At both ends. 

 (6) Ends convex, 

 (c) More or less circular. 

 2. With stem. 



(A) Stem expanding from base — with or 

 without barbing. 



(a) Base concave. 



(5) Base straight, 

 (c) Base convex. 



(B) Stem with sides parallel — ^with or 

 without barbing. 



(a) Base concave. 



(6) Base straight, 

 (c) Base convex. 



(C) Stem contracting from base — ^with or 

 without barbing. 



(a) Base concave. 

 (6) Base straight, 

 (c) Base convex. 

 Note 1. The proportion of the length of 

 the base to its breadth should be observed. 



Note 2. The notches in barbed specimens 

 may be vertical, horizontal or with varying 

 diameter. 



Note 3. The angles formed by the faces 

 (i. e., "bevel") should be observed. 



II. Scrapers. 

 Types. 



1. With one or more scraping edges. 



2. Without or with notch (including circular). 



III. Perforators. 



Differentiated by 



1. Cross-section. 



(A) Roxmd. 



(B) Quadrangular or irregular. 



2. Stem. 



(A) Without stem. 



(B) With stem. 



{a) Stem expanding gradually. 

 ( 6 ) Stem expanding suddenly. 

 IV. Hammerstones. 

 Types. 



1. Spheroidal. 



2. Discoidal. 



(A) "Pitted." 



(B) Not "pitted." 



3. Elongated. 



(A) Grooved. 



(B) Not grooved. 



Note 1. Practical or ornamental serration 

 may be applied to many forms. 



Note 2. Combinations of the types may 

 appear in one specimen and any type may be 

 infinitely varied by individual caprice.
