PREFACE. 



THE purpose of this book is to supply a course 

 of reading calculated to awaken the interest of the 

 pupil in the study of the life and habits of plants. 

 It is not to be judged as a complete work in itself, 

 but as a series of articles bearing on the subjects 

 of the lessons described in " Outlines of Lessons in 

 Botany." 1 



Four of the articles, Nos. II., III., XIII., and XV., 

 have been written especially for this Reader. Three 

 articles are translated from " Pflanzenleben," 2 and two 

 others owe much of their matter to the same book, 

 which is a very charming popular account of the most 

 recent discoveries in the physiology of plants. The 

 other chapters are from various sources. 



Sachs' "Lectures on the Physiology of Plants" 3 has 

 supplied several interesting notes, and is an invalu- 

 able work to the teacher who wishes to become more 

 acquainted with this fascinating new field of study.
