A PROGRAM FOR SAVING TREES 9 



executed. And we need skilled arboricultural 

 workmen in every city and town. 



The purpose of this book is to help all of these 

 groups to do a kind of work which has to be done, 

 and done well, in carrying out effectively each of 

 the three provisions of our arboricultural pro- 

 gram the prevention and treatment of wounds 

 and the physical repair of trees. It aims to 

 lay before the tree owner, or the man who is 

 responsible for the welfare of trees, the informa- 

 tion he needs for undertaking this kind of work 

 himself, and which he needs no less if he is to hire, 

 intelligently, men to do the work for him. It is 

 also intended to serve as a handbook for those who 

 now practice, or may take up, the work of tree 

 repair as a profession.
