 Practical Botany 



A study of plants as related to everyday 

 life, written from the point of view of the 

 pupil's interest and of pubUe needs rather than 

 that of the technical side of botany. The 350 

 illustrations really illustrate and supplement 

 the text, and in clearness of reproduction can 

 scarcely be improved upon. 



The Botany is usable under ordinary 

 school conditions, simple in organization and 

 style, practical in content, and illustrations, 

 and purpose, successful in actual use, and 

 approved by the great majority of the teachers 

 of the subject.
