The main object of the present communication is to formulate, briefly, certain results which have been obtained in the course of recent attempts to parallel some of the geological terranes in the Mississippi Valley. The suggestions they offer appear to have a much more than local bearing, and to affect the stratigraphy of the entire region. They also have an important influence upon the whole problem of general correlation and, perhaps, also, even upon our present system of geological classification.
