IMPORTANT FEATURES OF THE BOOK 



Usableness. Both the authors have had much experience in teaching botany to 

 large classes of beginners, and both are primarily interested in having the science 

 so presented that it will be full of meaning to the largest number of pupils. 



Simplicity. Technical terms are employed only where the use of ordinary 

 language would multiply words or cause ambiguity. 



Attractiveness. Those aspects of botany are most emphasized which mean 

 much to intelligent young people who are not likely to pursue the science in a 

 detailed way after their formal education is completed. To secure this end the 

 authors have constantly tried to use the botanical content and manner of presen- 

 tation that will be of interest and educative value to beginners rather than to 

 consider the relations of the course to any botanical courses that may follow. 



Practical Quality. The student is not drilled in the details of the phenomena 

 of mitosis or taught much histology, but he learns a good deal about the way in 

 which plants lay the foundations for the world's supply of food, timber, and fuel, 

 and enough of plant structure is presented to make clear how functions are per- 

 formed. He is given a rational basis for that part of sanitation which rests upon 

 a knowledge of bacteria and other destructive organisms. 



Territorial Range. The types of plant life and the plant regions discussed 

 are not those of any small portion of the country, but cover a wide range, includ- 

 ing some tropical forms. 



Effective Illustrations. More than three hundred fifty illustrations are used, 

 most of them from original drawings or photographs that are prepared by 

 naturalist artists expressly for this book, and these illustrations are selected to 

 serve as organic studies that are presented in the text. Technically and artisti- 

 cally they are the best that have been presented in a school textbook in botany. 



Educative Value. In the belief that the educative value of science study will 

 be enhanced by constantly leading the student to see that it is worth while, the 

 authors have included much relating to industrial, agricultural, horticultural, 

 and other interests, into the conduct of which a knowledge of technical botany 

 largely enters. This has been done without neglecting the essentials for a clear 

 understanding of the elements of botany as a science.
