PREFACE TO SIXTH EDITION

THis edition represents a thorough revision without essentially changing the basic organization and purpose of the book. In so doing the author has constantly kept in mind the necessity for presenting only enough descriptive facts, explanations, and discussions of interpretations to give the student a real foundation for a general understanding of the panorama of the ages as revealed in the rocks.

As heretofore, it is taken for granted that the student has a fair knowledge of the facts and principles of geology as usually taught in a first course in geology.

The Appendix contains simple outline classifications of plants and animals. Every student should, early in the course, be required to be reasonably familiar with the material there presented as a basis for gaining a proper understanding of the history and evolution of plants and animals.

Many hundreds of changes have been made in the printed text.

These range from very minor ones to others involving rewriting of numerous large and small sections, addition of new material in many places, and deletion of short and long statements in many other places.

Among the many new topics introduced in this edition are: The Grand Canyon of Arizona—A Lesson in Earth History; Collecting Fossils; Theory of Continental Drift; Diastrophism Through Geologic Time; The Earth's Interior; Trenton Group and Time; Raymond's idea of pre-Cambrian life; Franciscan Geosyncline; Cordilleran Geanticline;

Gulf Coast Geosyncline; Cordilleran Revolution; examples of Tertiary lakes; Ventura Basin; Faulut System of Western California; Geologic Effects of Glaciation; new theories on causes of the Ice Age; and Geologic History of the Sequoias.

More than 100 illustrations appearing in the fifth edition are not shown in the new edition. Many illustrations from earlier editions are retained because they still serve their purpose so well. Change, merely for the sake of change, has not been favored.

About go half-tone pictures appear for the first time. Also a number of the former pictures have been enlarged.
