Abstract
This study essays to compare, and in some degree to supplement, pollen analyses thus far published for Illinois. Even though results of studies of fossil pollens seem very similar, each pollen profile is individual and varies in many details from all other profiles. For this reason, each new analysis is more than a repetition of what has already been studied and reported; it is a possible verification of these previous studies and a valuable supplement to the growing science of pollen analysis. It is hoped that the preliminary study of fossil diatom valves found in this deposit can be correlated with the fossil pollen record, and possibly reveal valuable additional data in the quest for information on the history of the pond and of climates of its vicinity.
