"OHN DAVEY is the "father of tree surgery." His right to the title 

 has been fully and widely recognized. Great educational institu- 

 tions have given it the weight of their indorsement, and leading 

 magazines have confirmed it a//<?r searching investigations. 

 The tree surgery with which the name of John Davey is so inseparably con- 

 nected, however, is a scie^ice, to be practiced only by trained men. There is a 

 type of tree treatment to be encountered here and there which has no right to be 

 called tree surgery — it would better be described as tree butchery. 

 The Davey tree experts exclusively practice the science of tree surgery as discovered and 

 reduced to concrete form in the life work among tiie trees of John Davej-. Thej^ are given 

 a thoroKffh and ris^id training in the Davey Institute of Tree Surgery, at Kent, Ohio — the 

 only school of the kind in the world. 



Many c?-imes against the trees are committed in the name of tree surgery. Even as the devil stole 

 the livery of heaven to advance his selfish ends, tree butchers are masquerading as tree surgeons. 

 Once in a while the lure of gold tempts a Davey man from his allegiance to his profession, and he 

 falls to the depths of connection with the mal-practitioners of tree surgerj'. 



The scientific basis of tree surgery as John Davey teaches it stands as an undisputed fact. The 

 character of the instruction in its theory and practice given in the Davey Institute of Tree Surgery 

 has been investigated and approved by high authorities. The permanent efficiency of the work of 

 the Davey tree experts has been demonstrated conclusively in the most radical tests. 



Ample and conclusive proof of these assertions will be cheerfully furnished by The Davey Tree 

 Expert Company. For your own protection and for the trees' own sakes, demand equally 

 complete credentials from others. Ask them in what school of tree surE^erythexr workmen 

 were trained, and to produce evidence that their work has stood the test of years. 



Above all, beware of the man who claims to be a graduate of the Davey Institute of 

 Tree Surgery, but not now connected with the Davey Tree Expert Company. Get his 

 story of why he left us, and let us give you our story of why he did. Learn of the 

 obligations our men assume when they enter our school and our employ — and then 

 decide whether you will be safe in hiring a man who has broken his contract with us.
