Are you fooling 
yourself about 
your trees? 
ARE you making the dangerous mis- 
take about tree surgery that was 
made by the owner of the tree 
shown herewith? (Small photograph No. 
1 betow.) Read the following facts — 
they may prove a revelation. 
The owner of the tree shown here thought 
that Tree Surgery was merely a matter 
of patching cavities with cement — some- 
thing which almost any clever fellov 
could do. 
The result to his trees was costly and 
disappointing. Davey Tree Surgeons 
found that this tree (Photo. 1), which 
the owner thought had been saved, was 
in a really critical condition, disease and 
decay continuing unchecked behind the 
fillings. The entire work had to be torn 
out and done again — done right. Photo- 
graphs Nos. 1 , 2, 3 and 4 — a typical 
tree — tell the story. (See descriptive 
matter under photographs.) 
Tree Surgery a Specialized Science 
Tree owners sometimes confuse Tree 
Surgery with Forestry. These two pro- 
fessions are as widely separated as den- 
tistry and medicine. 
The Forester is trained to deal with 
trees in the mass, culturjng them pri- 
marily for lumber suppl>-. As Bernard 
E. Fernow, Dean of Faculty of Forestry, 
University of Toronto, puts it: "The 
forester grows trees }iot to be preserved, 
but to be harvested." 
The Tree Surgeon, on the contrary, is 
interested in the individual tree; to pro- 
long its life is his sole aim. He knows 
little or nothing about forestry and is 
entirely unequipped in training and ex- 
perience to cope with its problems. 
Forestry is a worthy profession doing 
a great economic work. But to entrust 
the saving of your priceless specimen 
trees to a Forester is certain to result 
in disaster. 
For real Tree Surgery, there is only 
one safe place to go — to Davey Tree 
Surgeons. 
Davey Tree Surgery Is Safe 
Sdfc — because it is time-proved, its record 
of successful performance for thousands 
of estate owners spanning a generation. 
Safe — because no Davey Tree Surgeon i? 
allowed ai.y responsibility until he has 
conclusively demonstrated his fitness. He 
must have served his full course of thor- 
ough, practical training and scientific 
study in the Davey Institute of Tree 
Surgerv — a school, the only one of its 
kind in the world, which we conduct for 
the specific purpose of drilling our men 
according to Davey methods and Davey 
ideaU. 
Safe — because Davey Tree Surgery has 
been endorsed as best by the United 
States Government, after exhaustive offi- 
cial investigation. 
Safe — because Davey Tree Surgeons are 
picked men. thoroughly trained, conscien- 
tious, intelligent, courteous, in love with 
their work. 
Safe — because the Davey Company is a 
successful and responsible house, amply 
able to make good in every instance and 
not needing, for the sake of temporary 
existence, to sacrifice in the slightest de- 
cree its high standards.

No. 1. This tree had 
started to decay. The 
owner saw this, but did 
not realize that it re- 
quired scientific treat- 
ment. So he allowed 
an untrained man to 
"patch the holes" with 
cement. This "patch- 
ing" was worse than 
useless it was positively 
harmful. 
No. 2. The cement 
patch. s were removed by 
Davey Tref Surgeons, 
and there was revealed 
an appalling condition 
of disease and decay. 
The tree had become a 
mere shell, liable to 
crash to pieces in any 
severe storm. 
.No. 3. Davey Tree 
surgeons removed every 
particle of decay, dis- 
infected the entire cavity 
to destroy the existing 
disease, thoroughly wat r- 
proofed the inside, cut 
watfr sheds to exc'ud.' 
moisture and carefully 
braced the shell me- 
chanically. 
No. 4. Here is the finished re- 
sult of science plus skill. The 
strength of the tree, destroyed by 
decay, has been restored by me- 
chanically perfect Davey methods. 
The filling was put in by sections 
to permit the normal sway of the 
tree without cracking the filling. 
The new bark is growing over the 
••dges of the filling and in time 
will cover it entirely. This tree 
is now in perfect health — perma- 
nently saved — responding gloriously 
'0 the marvelous skill of Davey 
Tree Surgeons who know how and 
why.
