Combed ware presented three small nodes to be followed by a larger 

 node early in the occupational range; a second and third sequence 

 of nodes appeared to be followed by a small node just before this ware 

 finally disappeared from the scene. Plain ware was not at all pre- 

 dictable in that it rises and falls in irregular pulsations gaining steadi- 

 ness shortly after the midpoint in the graph. Combing and textile- 

 impressed were the only wares on the upgrade, while fabric-marked, 

 plain, and combed wares gradually diminished in importance and 

 finally disappeared shortly before the basin was deserted and the 

 textile-impressed had gained complete control of the field.
