pS. ?fo; I5T HOSTERMAN SITE — ^MILLEJR 193 



Cheyenne River were apparently identifiable with Arikara ceramics 

 as described by Strong (1940, pp. 368-369, 381). The Hosterman 

 site, situated about 40 miles upstream from the mouth of the Cheyenne 

 River, could fall well within the sphere of the Arikara settlement 

 pattern and hence one would expect to find to a certain extent com- 

 parable pottery forms and types of this group at the site. There is 

 close resemblance between the two. 



ARTIFACTS OTHER THAN POTTERY 



CHIPPED-STONE ARTIFACTS 



PEOJECTILE POINTS 



Six hundred fifty-nine projectile points, either whole or frag- 

 mentary, were recovered. Several varieties of stones were used in 

 their manufacture : quartzite, chalcedony, and chert. Two specimens 

 were made of obsidian. Nearly all are thin, and a number show a 

 primary scar on one face, whereas most were made by secondary chip- 

 ping of a small detached flake. The final shaping of the edges was 

 accomplished by flaking from both sides. Two hundred sixty-nine 

 were sufficiently complete to allow for classification. Flaking is neat 

 and rather delicate in most specimens, and since it proceeded from both 

 sides the resulting point is very symmetrical and slightly lenticular 

 in cross section. 



Most of the stone used in the manufacture of projectile points oc- 

 curs in the vicinity of the Hosterman site, in the riverbed or on the 

 terraces around the site. Some, like obsidian, had to be brought into 

 the area from other vicinities. 



The arrow points of the Hosterman site are small, light, and pres- 

 sure flaked. Four basic styles are represented as well as the inevitable 

 scattering of deviants. 



Group 1 (pi. 22, A) ; 62 specimens. — Triangular in shape with straight or slightly 

 convex edges ; sides are slightly longer than the base ; straight bases as a rule, 

 but there are some slightly concave or convex bases that occur rarely. 



Length: Mean of 14 mm., ranges from 13 mm. to 19 mm. 



Width: Mean of 13 mm., ranges from 9 mm. to 18 mm. 



Thickness: Mean of 3 mm., ranges from 2 mm. to 4 mm. 

 Gboup 2 (pi. 22, B) ; 112 specimens. — Isosceles triangular in shape with straight 

 or slightly concave edges ; straight or concave bases. Maximum width at 

 base. 



Length: Mean of 25 mm., ranges from 20 mm. to 29 mm. 



Width: Mean of 14 mm., ranges from 11 mm. to 17 mm. 



Thickness: Mean of 3 mm., ranges from 2 mm. to 6 mm. 

 Geoup 3 (pi. 23 A) ; 21 si)ecimens. — Triangular with straight or convex edges, 

 straight or convex bases. Maximum width at base. 



Length: Mean of 34 mm., ranges from 24 mm. to 43 mm. 



Width: Mean of 24 mm., ranges from 19 mm. to 29 mm.
