The Elements of Geology

"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."
