PREFACE 



THIS book has been written to assist in impressing upon 

 the young the value of our forests and to give them some 

 appreciation of what is being done, as well as of what must 

 yet be done, in order to preserve them. It is not a hand- 

 book on forestry, but contains interesting information 

 which, it is hoped, will tend to create a healthy public 

 opinion regarding the use and care of trees. 



While the book is really the expression of that apprecia- 

 tion of trees which comes only from long and intimate 

 acquaintance, yet the literature on the subject has been 

 freely used, and the author wishes to acknowledge the help 

 received from the following : Sargent's " Manual of the 

 Trees of North America " ; Britton's " North American 

 Trees " ; Fernow's " Care of Trees " ; Britton and Brown's 

 "Illustrated Flora of the Northern States and Canada"; 

 "Gray's New Manual of Botany" by Robinson and Fer- 

 nald ; Rydberg's "Flora of the Rocky Mountains and Ad- 

 jacent Plains "; Coulter and Nelson's "Rocky Mountain 

 Flora" ; and Macoun's "Catalogue of Canadian Plants." 



Very particular mention should also be made of the many 

 excellent publications of the Forestry Branch of the Depart- 

 ment of the Interior; and special thanks are due to Mr. 

 R. H. Campbell, Director of Forestry, for valuable sugges- 

 tions and assistance, as well as for a very careful and sug- 

 gestive reading of the proof sheets by the staff of the 

 Forestry Branch.
