Th e author has ventured, therefore, toother to depart from the common usage which subdivides geologydepart geology into a number of departments,mdash;dynamical, structural, physiographic, and historical,mdash;and to treat in immediatephysiographic, immediate connection with each geological process the land formsconnection forms and the rock structures which it has produced.
