"Geology is a science of such rapid growth that no apology is expected when from time to time a new textbookapology textbook is added to those already in the field. The presentis present work however is the outcome of the need of a text-book ofwork of very simple outline in which causes and their consequencesvery consequences should be knit together as closely as possible a needshould need long felt by the author in his teaching and perhaps bylong by other teachers also. Th e author has ventured therefore toother to depart from the common usage which subdivides geologydepart geology into a number of departments dynamical structural physiographic and historical and to treat in immediatephysiographic immediate connection with each geological process the land formsconnection forms and the rock structures which it has produced."
