PREFACE 



THE series of nature study lessons furnished in this 

 book was worked out in the class room and in out- 

 door excursions with children. 



Most of the lessons are studies of plant and animal 

 life as it presents itself in one locality; but the ob- 

 jects studied are found in most temperate regions, 

 and the lessons can be modified to suit almost any 

 region of the United States. 



The method of treatment is also somewhat fully 

 indicated by questions and answers. These work 

 out more fully the plan for primary grades outlined 

 in the "Special Method in Elementary Science," 

 which also contains full references to the best books 

 and helps for primary grades. 



Many of these lessons were originally published 

 as a part of the first edition of the " Special Method 

 in Elementary Science." But the series of lessons 

 is now enlarged and published separately.
