Thus far no Oneota pottery or Hopewellian pottery has been 
found in this area. The Middle Mississippi shell tempered 
pottery recently mentioned by Drs. Dellinger and Dickinson has 
limited similarity to our Imperial Plain ware but is probably 
considerably softer.! 
Effigy bottles, bowls with annular ring bases and tripod pots 
are absent. Ollas, or jars, bowls and water bottles are similar to 
East Arkansas forms. However, there is no indication of Deason- 
ville, Coles Creek or Marksville ceramic influence. The Plattin 
Clay Tempered ware from the Plattin aspect is certainly sug- 
gestive of southern influence according to Dr. James Griffin’s 
pottery analysis report. The presence of large numbers of sherds 
from the Kimmswick focus with red slipped surfaces is sug- 
gestive of the Arkansas River focus of Eastern Arkansas as- 
pect of Middle Mississippi phase. 
Our St. Jo Polish Plain is typical of the thin hard finely shell 
tempered ware from Cahokia where it is called Powell Polish 
ain. 
Both the Kimmswick and the Plattin focus have traits that 
can be linked with aspects of the Upper, Middle and Lower 
Mississippi phases. Those traits that are found mainly with one 
or more Upper Mississippi aspects include pipes for reed stems, 
pipes with projecting stems made of claystone, polished wedge 
shaped bone tools, arrowshaft straighteners and considerable 
variation in olla or jar size. Those traits that are commonly found 
with the Upper and Middle Mississippi phases include biconcave 
discoidals, polished celts without flaring bits, small isosceles 
projectile points finely chipped, cut shell disc beads perforated 
centrally, bone awls and needles, incising on shoulders of ollas 
or jars, lip flanges, more than one pottery ware, extended human 
burials with or without grave furniture and use of stone box 
graves. Those traits that are commonly found with the Middle
