PREFACE 



THE reasons for writing this book are : (i) that 

 no work of a similar kind has been published ; 

 (2) that numerous inquiries as to the treat- 

 ment of tree wounds and diseases suggest that 

 such a book is required ; and (3) the writer's 

 knowledge of the subject, the result of many 

 years' practical work and observation, has caused 

 him to relate his experiences in the matter. 



The book, too, has been written by special 

 request, and an apology is due for its non- 

 appearance three years ago, as arranged. Un- 

 foreseen circumstances, however, prevented this 



being done.
