PREFACE 



In presenting this volume, the author is aware that there 

 are several excellent books, dealing with one phase or another 

 of tree life, already before the public. It is believed, how- 

 ever, that there is still need for an all-round book, adapted 

 to the beginner, which gives in a brief and not too technical 

 way the most important facts concerning the identification, 

 structure and uses of our more common trees, and which 

 considers their habits, enemies and care both when grow- 

 ing alone and when growing in groups or forests. 



In the chapters on the identification of trees, the aim 

 has been to bring before the student only such characters 

 and facts as shall help him to distinguish the tree readily 

 dining all seasons of the year. Special stress is laid in each 

 case on the most striking peculiarities. Possible confusion 

 with other trees of similar appearance is prevented as far 

 as possible through comparisons with trees of like form or 

 habit. 



Only such information is given concerning the structure 

 and requirements of trees as will enable the reader better 

 to understand the subsequent chapters. In the second half 

 of the book, practical application is made of the student's 

 general knowledge thus acquired, and he is acquainted with 

 the fundamental principles of planting, care, forestry, wood 

 identification and nature study. 



The author recognizes the vastness of the field he is 

 attempting to cover and the impossibility of even touching,
