Excerpt from Outlines of Geologic History, With Especial Reference to North America: A Series of Essays The essays in this volume were presented before Section E, of the American Association for the Advancement of Science, at the meeting in Baltimore in December, 1908. The original plan of the papers involved the formulation of the principles of correlation, as applied to the formations of different periods. This plan was conceived by Bailey Willis, then vice-president of Section E, and was carried out With much success. The several chapters have appeared in the J oumal of Geology, since their presentation at Baltimore. They present in broad outlines a summary of certain phases of existing knowledge of N orth American geology, and are now bound together in the belief that students of geology in this country and abroad will welcome them in this more convenient form. The paleogeo graphic maps by Mr. Willis form a valuable part of the volume. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
