JOHN DAVEY 

 The Father of Tree Surgery 



WHAT is the physical condition of your trees 

 — those splentlid monuments of the genera- 

 tions that have gone before? Are you sure they 

 contain no hidden defects which, if left alone, will 

 speedily destroy them? Have you ever considered 

 that if you lose your trees by failure to protect 

 them and preserve their lives, it will not be pos- 

 sible to replace them, in their present grandeur, 

 within your lifetime, or in that of your children, or 

 even, in many cases, in that of your grand-children? 



When you have considered 

 these points with the serious- 

 ness they deserve, and have 

 decided to have the health of 

 your trees looked after, con- 

 sider well, also, whether their 

 ills shall be treated by expert 

 tree-surgeons or by novices — 

 by the man who originated 

 tree-surgery and those whom 

 he has adequately trained, or 

 by amateurs who lack both 

 knowledge and experience.
