THIS textbook for secondary schools brings the study ot 

 botany into close touch with the practical business of 

 life by emphasizing its relations with agriculture, econo- 

 mics, aud sanitation. It meets the college entrance require- 

 ments. 



^ The subject has been simplified and popularized in order 

 to stimulate the interest and enlist the cooperation ot the 

 pupil. Technical language is used only as tar as is required 

 by scientific accuracy. The student is encouraged to acquaint 

 himself by observation and experiment with the structure and 

 activities of plants, and then to follow up his discoveries in 

 their practical bearings upon such of the common interests ot 

 our daily life as are especially atfected by them. 

 ^ Each topic is introduced, wherever practicable, by simple 

 experiments or other laboratory exercises, which require only 

 such materials as are familiar and easily obtainable. Among 

 the important and interesting matters, concerning which prac- 

 tical application is made, are the economic importance of seeds, 

 food tests, the life of seeds, composition of soils, tillage, for- 

 estry, influence of plants on the atmosphere, cross fertilization, 

 plant breeding, factors in the evolution of species, seedless 

 fruits and vegetables, influence on plants of temperature, 

 moisture, soil, light, air, and winds, zones of vegetation, the 

 economic importance of bacteria, sterilization, disinfection, 

 yeasts, and ferments.
