This book contains a great variety of experiments, over two hundred and 

 fifty in number, all of them simple and easily performed by the use of uten- 

 sils to be found in most homes or which can be procured in the ordinary 

 grocery or drug store, and the directions for the conduct of each experiment 

 are so simple and clear that they will tempt the young student on the farm to 

 try for their solution. These experiments have all been chosen because of their 

 practical character, and in all cases the application of the experiment is made 

 to farming, gardening, hygiene, sanitation, and to everyday life generally. 

 The experiments are so arranged that each one leads naturally to the one 

 next following, and the general order of topics is the one suggested by observ- 

 ing the growth of a plant. Especial attention is given in the book to certain 

 important topics hitherto neglected; for example, soil, bacteria, diseases of 

 plants, and plant-breeding. The central idea throughout the work has been 

 to select significant experiments; that is, those which illustrate fundamental 

 laws and far-reaching principles, and then to simplify the experiment to the 

 utmost. 



The illustrations, which number over two hundred and fifty, are all original 

 and interesting. 



" Numerous questions which young people ask about plants are best an- 

 swered by themselves, according to Professor W. J. V. Osterhout of the Uni- 

 versity of California. To put them in the way of doing this so far as possible 

 is the purpose, the author states, of a comprehensive and well-written book 

 which he has just given the public. The book is particularly well adapted to 

 the classroom, but the nature of its contents makes it of interest to everybody 

 who is interested in a detailed study of plant life. . . . The book is so pro- 

 fusely illustrated and the text of such an interesting nature that it is an educa- 

 tion in the development and behavior of plants, merely to read through the 

 volume." Suburban Life.
