Four typical examples of per- 

 fect healing 



Showing how Nature 

 unfailingly responds to 

 the scientific methods 

 of Davey Tree Surgeons 



INJATURE responds 

 to the Tree Sur- 

 geon's art by healing 

 over the filling — // 

 the work has been 

 properly done. Tne 

 rapidity of the 

 healing depends on 

 the size of the cavity 

 and the vitality of the 

 tree. Illustrated here 

 are four typical examples of perfect 

 healing following Davey Tree Sur- 

 gery. They are merely representa- 

 tive of the many thousands of suc- 

 cessful cases handled by the Davey 

 organization in the past generation. 



Photograph No. 1 shows a tree at 

 theChristian Herald Children's Home, 

 Nyack, N. Y. This tree had a split- 

 ting and badly decayed crotch, requir- 

 ing a filling from the top of the crotch 

 almost down to the ground. Note 

 how the bark has completely healed 

 over the filling in about four years. 



Photograph No. 2 was taken on 

 the estate of John D. Archbold, 

 Tarrytown, N. Y., and shows a tree 

 with a filling in the side of the trunk. 

 Almost healed over in about six 

 years. 



Photograph No. 3 illustrates a tree 

 on the estate of the late Julius French, 



Wickliffe, Ohio. Filling at the base 

 of the trunk with about five years' 

 healing. 



Photograph No. 4 — A tree at Kent, 

 Ohio, treated by the students of the 

 Davey Institute, class of 1913. Show- 

 ing about two years' healing; coun- 

 tersunk boltheads completely healed 

 over. Filling in the crotch and on 

 one limb partly healed over. 



To be perfect, Tree Surgery must 

 embody the three following principles: 

 All decay must be removed and fur- 

 ther decay prevented. The cavity 

 must be so prepared that the filling 

 will remain permanently in place. 

 All foreign matter must be excluded, 

 especially water. It is difficult to 

 say which is most important. They 

 are inter-dependent. If the operator 

 fails in one he fails entirely. These 

 principles embody both science 



and mechanics. A 

 Tree Surgeon must be 

 trained in mind and 

 in hand. He must 

 have both knowledge 

 and skill. A man who 

 has only theoretical 

 knowledge fails miser- 

 ably. An unscientific 

 operator works with- 

 out understanding.
