8 HAND-BOOK OF TREE-PLANTING. 



so called, or even to go over the catalogue of 

 trees indigenous to this country, more than four 

 hundred in number, but treats only of a limited 

 class and such as have a recognized economic 

 value that commends them to the attention of 

 any who are desirous of planting for use and 

 profit. 



But while this is the author's special object, 

 he has endeavored to treat the subject in such 

 a manner as will make the work a proper guide 

 to the tree-planter, whoever he may be, or what- 

 ever may be his object in planting. The laws of 

 growth and the conditions of success in planting 

 are essentially the same, whether one plants a 

 forest or a single tree, whether he plants for use 

 or for ornament. Economic considerations may 

 lead to a variation of treatment in some re- 

 spects. These are easily specified, but the gen- 

 eral principles which govern all cases alike re- 

 main the same. 



It has seemed to the author that he might 

 best meet the demands of the subject by casting 

 what he has to say in the form of answers to the 

 specific questions Why to plant? Where to 

 plant? What to plant? and How to plant?
