SIX SALIENT POINTS. 



The new pedagogy of Physical Geography receives in this book its first 

 adequate presentation. 



Hence, this text meets the present requirements of high school and 

 college-entrance work perfectly and in full detail. 



Treatment adapted to the early years of the course the book will interest 

 pupils aged fourteen. 



Statements throughout are not "merely theoretical, but definitely concrete, 

 appropriately illustrated, and logically summarized. 



Topics cover "The Physical Environment of Man:" The Earth as a 

 Globe, the Ocean, the Air, and the Land in increasing proportion. 

 ' The exquisite half-tone illustrations far surpass in beauty, helpfulness, 

 and number anything before attempted. A most important and significant 

 feature. 



THE IDEAL COURSE AND GILBERT AND 



BRIGHAM'S BOOK. 



This book meets fully, in minute detail, and for the first time, all 

 the specifications set forth in the Report of the Committee on College 

 Entrance Requirements to the National Educational Association in 

 1899. It keeps accurately to the definition laid down ; it furnishes the 

 requisite kind and amount of instruction to train the observation and 

 to prepare for later special courses in science ; and it elevates physical 

 geography beyond cavil to the proper plane for a college-entrance 

 requirement, by organizing its content to its highest capacity as a 

 pedagogic discipline.
