particles mixed into the clay. The surface is indented with deep 
punch marks executed at an angle with a blunt instrument. The 
closest analogy to this ware is the crushed rock ware from Ful- 
ton County described on page 48 of Rediscovering Illinois by 
Cole and Deuel. Thus far this ware has been found at only 
one site. 
Shell Tempered Pottery 
All of the above wares have grit tempering and generally a 
cord roughened surface. Differing from these wares in temper- 
ing and other considerations is the series of wares described be- 
low. These are shell tempered and generally have smoothed 
surfaces. 
Imperial Plain (B) 
This ware is shell tempered and has a smoothed brown to 
gray surface. The shell is crushed fine for smaller pots and 
coarse for large pots. The ware is harder (2.5-3) where the 
shell tempering is present but is soft (2-2.5) where the temper- 
ing has leached out. There are several pot shapes including 
water bottles, beakers (beanpots), large and small shallow and 
deep bowls, bowl forms with flaring rims, seed bowls, plate and 
olla or jar forms. Occasionally the ware had a red slip and thick 
sherds from large shallow bowls often have fabric impressed 
surface finishes. Handles (loop type) are present on olla or jat 
forms. Effigy flanges are occasionally found from shallow bowls. 
The only decorations discovered thus far are the red slip men- 
tioned above and etching after firing on the upper surface of the 
plate rims. The closest analogy to this ware is the “dull gray 
ware,” described on p. 49 of Rediscovering Illinois and St. Clair 
Plain. 
There appear to be subdivisions of this ware from the Her- 
rell Village (Location XII, Jv55). A comprehensive report will 
be issued after investigations are completed at this important 
site. 
St. Jo Polish Plain (Bz) 
This ware is thin and hard (3.5). The tempering is finely 
crushed shells. The texture is compact and the surface has a
