RIGGS WARE 



Riggs Plain Rim 

 (PL 3, 6, d-h; pi. 6,e) 



Sample: 619 rim sherds, representing about 381 vessels, and one restored ves- 

 sel. 

 Decobation : 



Lip: On 237 sherds there are oblique or vertical tool impressions on the lip 

 or on the outer edge of the lip. Circular and oval punctates and tool- 

 impressed crosshatched lines, as well as fingernail impressions, occur on 

 some lips (pi. 3, e-g). Three rims bear oblique cord-impressed lines, 

 and seven rims have closely spaced castellations (pi. 3, d). The remain- 

 ing rims have plain lips (pi. 3, fc) . 

 Rim: Plain, with some horizontal smoothing over grooved paddle impres- 

 sions. A few rims have horizontal paddle impressions unmodified by 

 smoothing. A single decorated rim is included in this type (fig. 1, c). 

 Shoulder: Sherds of 13 vessels are incised with various designs, most of 

 which are rectilinear. Four design motifs are present : 



(1) Incised chevrons of three or four lines alternate with a triangular 



"bear foot" element (fig. 1, a-h). The restored vessel bears this 

 design, executed by a stab-and-drag technique (pi. 6, e). 



(2) Incised "drooping corn stalks" or oblique incisions are superim- 



posed over horizontally incised lines (fig. 1, f-g). 



(3) Panels of opposed diagonals occur (fig. 2, &-c). 



(4) Sherds from two vessels have incised, concentric circles on the upper 



shoulder (fig. 2, <?). 

 Fobm: 



lAp: Round, pointed, or flat, depending upon the presence and type of deco- 

 ration. Thickness, 4 to 10 mm., averaging 6 mm. 

 Rim: Straight and vertical to somewhat outflared. Heights are 10 to 70 



mm., averaging about 35 mm. ; thickness, 5 to 12 mm., averaging 7 mm. 

 Size: The projected orifices of 12 rim sherds indicate diameters between 

 120 and 346 mm. :
