PARAGRAPHS FOR THE TEACHER ' 



(Revised for second edition.) 



THIS book is made for the pupil : " Lessons with 

 Plants" was made to supplement the work of the 

 teacher. 



There are four general subjects in this book : the 

 nature of the plant itself; the relation of the plant 

 to its surroundings; histological studies; determination 

 of the kinds of plants. From the pedagogical point 

 of view, the third is the least important: the writer 

 has inserted it because so many schools want it. Each 

 of the subjects is practically distinct, so that the 

 teacher may begin where he will. Few schools will 

 desire to pursue all the four parts 



The notes in small type at the ends of the chap- 

 ters are intended as suggestions and to supply infor- 

 mation to teachers: they are not necessarily for class 

 use. The explanation of karyokinesis, for example, on 

 page 239, is intended to answer frequent inquiries 

 from teachers; it is not to be taught to beginners. 

 The main object of the "Notes," however, is to sug- 

 gest experiments and corollary observations. 



The schools and the teachers are not ready for 

 the text -book which presents the subject from the 

 view -point of botanical science. Perhaps it is better
