104 BUREAU OF AMERICAN ETHNOLOGY [Bull. 189 



FoBM : 



Lip: Flat. 



Rim: Straight, with the rim blending smoothly with the shoulder, of form 

 B (fig. 13). 

 Comments : This example may be a cord-impressed variety of the horizontally 

 incised, flaring rim sherds ( Group 2 ) . 



14. Cobd-Impeessed Rim, Example C (pi. 11, i). 

 Sample : 1 vessel. 



Paste and sueface finish : See Example A. 

 Decoration : 



Lip: Chevrons, composed of shallow, oblique tool Impressions on the interior 



and exterior. 

 Rim: Seven horizontally applied cord-impressed lines. 



Shoulder: Herringbone pattern, the only occurrence of this design in the 

 site sample. 

 Foem: 



Lip: Pointed. 



Rim: Straight to slightly recurved, of form D (fig. 13). 



Shoulder: Flat and sloping, with an angular break at the juncture with 



the body. 

 Size: The orifice measures 95 mm. in diameter. 

 Comments: This example may be another cord-impressed variety of the hori- 

 zontally incised vessels with flared rims (Group 2) . 



15. Coed-Impeessed Rim, Example D (pi. 11, c). 

 Sample: 1 vessel. 



Paste : 



Temper: Coarse grit. 



Texture: Rather crumbly, with loosely compacted clay. 

 Surface finish : Horizontally smoothed on interior and exterior. 

 Decoeation : 



Lip: Crosshatched. 



Rim: Five horizontally applied cord-impressed lines. 

 Form: 



Lip : Beveled down and out. 



Rim: Straight, of form J (fig. 13). 

 Comments : This rim does not closely resemble any previously described pottery. 



16. RiGGS Cross-Hatched Rims (pi. 12, d). 



The sample consists of five sherds from four vessels. The lip of one vessel 

 is carefully crosshatched, but the same design on the outer rim is irregularly 

 applied. The paste is coarse and the grit is large-grained. This single sherd 

 is from House 4, while the rest of them are from the surface. 



The other sherds are more carefully crosshatched, with oblique tool impressions 

 on the lips of two vessels, and a plain lip on the other vessel. The paste and tem- 

 per of these sherds is less coarse than that of the vessel from House 4. Each 

 of the sherds of this type is identical to examples as decribed from the Paul 

 Brave site (Wood and Woolworth, 1964), a component of the Thomas Riggs 

 Focus a few miles north on the Missouri River. 



17. Riggs Straight Rim (pi. 13,1). 



The 12 rims from the 9 vessels of this type are distinguishable from the other 

 sherds from the site in having (a) a coarse temper and a crumbly, granular 

 texture, (b) cross sections 8 to 14 mm. thick, as opposed to cross sections 4 to 

 8 mm. thick in the majority of rims, and (c) contorted cores, in contrast to the 

 more commonly laminated cores. Vertical rim projections occur on two rims.
