THE Bergen and Caldwell Botanies have been received with 

 enthusiasm by teachers the country over. They meet modern 

 teaching conditions, placing the emphasis on those aspects of 

 plant life that are particularly worth while for general knowledge. 

 They give definite treatment to plant diseases, bacteria and their 

 relation to gardening and to sanitation, forestry, plant breeding, 

 and the application of botanical facts to agriculture, horticul- 

 ture, and other industries. At the same time they furnish a thor- 

 ough and well-proportioned grounding in the science of botany. 



The text is written for beginning students and is always clear 

 and interesting. Technical terms are used sparingly and when 

 used are carefully explained. Throughout the authors empha- 

 size the dynamic side of botany. They do not treat the plant 

 primarily as a subject for dissection or for making preserved 

 specimens, but as an organism with a living to make under con- 

 ditions sometimes favorable and sometimes unfavorable. 



The illustrations are numerous, pertinent, and of unusual 

 technical and artistic excellence. They are from original draw- 

 ings and photographs prepared by naturalist-artists expressly 

 for these books. 



" Introduction to Botany" offers a distinctly elementary pres- 

 entation for shorter courses. " Practical Botany " contains an 

 abundance of material for a full year's work.
