 A Text-Book of Geology. 



By Professor ALBERT PERRY BRIGHAM, of Colgate Uni 

 versity. 477 Pages. 295 Illustrations. 12010. Cloth, $1.40. 



This superb text-book is the best account for secondary 

 schools of the earth's marvelous origin, of the processes that 

 brought the ordered world out of chaos, and of the phenomena 

 of geologic evolution considered dynamically, structurally, and 

 historically. The planet's life history is told with directness, 

 brevity, and pedagogic fitness. The text is supplemented with 

 295 exquisite photographic illustrations, many taken by Professor 

 Brigham for this work. An exceptional success in text-book 

 writing and text-book making.
