INTRODUCTION iii 



ters with any readers who will be so good as to 

 give him the benefit of their ideas and their ex- 

 perience in the field of tree repair. 



Some readers, to whom this book is an intro- 

 duction to the work it describes, may at times feel 

 that its directions are too general, and its state- 

 ments too often qualified. A brief practical ex- 

 perience will show them the necessity for a certain 

 degree of generality. No two trees are alike. In 

 order that directions may not be misleading, they 

 must often leave much to the judgment of the 

 operator. 



To make the book of positive practical value 

 the author has overcome the extreme delicacy of 

 so many writers in glossing over the names of man- 

 facturers and their products. It is his honest con- 

 viction that in giving the results of his experience 

 that his statements should be put in the most 

 straightforward manner possible, without the con- 

 cealment of a single detail that may be valuable or 

 helpful to his readers. He has no logs to roll but 

 merely the desire to educate. 



During the preparation of the book the writer 

 has received valuable help from many people. 

 Mr. M. H. Horvath of Cleveland, landscape 

 architect and consulting forester, and Mr. John 

 Boddy, city forester of Cleveland, have answered 

 many enquiries, and Mr. Boddy has furnished the 

 originals of several photographic illustrations.
