FOREWORD 



When this little book was prepared, four years ago, its 

 primary purpose was to meet the needs of landscape garden- 

 ers; but I entertained a hope that the provision of a simple 

 workable method of naming the usual woody plants met with 

 in our northern climate might gratify a universal wish to 

 know the names of such things, and indirectly stimulate a 

 real knowledge of one part of nature by the many nature 

 lovers who find it difficult to obtain an introduction to many 

 of the friends of their rambles. The need of a new issue is 

 a gratifying indication that my hope that it might prove 

 useful was not ill founded. In the present edition, correction 

 has been made of such errors as have come to my notice, and 

 the scope of the book has been enlarged by inclusion of a few 

 additional types; but the purpose of keeping it within com- 

 pact bounds has been adhered to. While the keys might have 

 been based more exclusively on characters patent to the un- 

 aided eye and obvious to the untrained understanding, they 

 are based still on characters intended to make close observa- 

 tion necessary and to give a correct understanding of the 

 general morphology of plants.
