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 below.) Read the following facts — 
they may prove a revelation. 
The owner of the tree shown here tliought 
that Tree Surgery was merely a matter 
of patchint; cavities witli cement — some- 
thing which almost any clever fellov 
could do. 
The result to his trees was costly and 
disappointing. Davey Tree Surgeons 
found that ihis 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 he torn 
out and done again— f/o«(; right. Photo- 
graphs Xos. 1. 2, i and 4 — a typical 
tree — tell the story. cSee descriptive 
matter under photographs.) 
Tree Surgery a Specialized Science 
Tree owners sometimes contuse 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, culturing them pri- 
marily for lumber supply. As Bernard 
E. Fernow, Deati of Faculty of Forestry, 
L'niversity of Toronto, puts it: "The 
forester grows trees iiot 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 know;s 
little or nothing about forestry and is 
entirely unequipped in training and ex- 
perience to cope w'ith 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 
Safe- — 'because it is tiTiie-proved, its iccord 
of succe;-sful performance for thousands 
of estate owners spanning a generation. 
Safe — because no Davey' Tree Surgeon is 
allowed any 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 
I he specific purpose of drilling our men 
according to Davey methods and Davey 
i<leal>. 
Safe — because Davey Tree Surgery has 
been endorsed as best by the United 
States Government, after e.xhaustive offi- 
cial investigation. 
Safe — because Davey Tree Surgeons are 
flicked 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- 
gree its high standards.

No. 1. This tree bad 
started to decay. The 
owner saw this, hut did 
not realize that it re- 
([uired scientific treat- 
ment. So he allowed 
an untrained man to 
■'patfh the hole-s" with 
cement. This "pateh- 
jng" was worse than 
useless it was positively 
harmful. 
.No. 2. The ciment 
patches were removed by 
Davey Tree Surgeons, 
and Iliere was revealed 
an appalling condition 
of disease and decay. 
The tree had l>ecome a 
mere shell, liable to 
crash to pieees in any 
severe .storm. 
No. 3. Davey Tree 
Surgeons removed every 
partieie of decay, dis- 
infected the entire cavity 
to destroy the existing 
disease, thoroughly water- 
proofed the inside, cut 
water sheds to exctud' 
moisture and carefully 
braced the shell me- 
chanieally. 
-Nil. 4. Here is the finished re- 
sult of science plus skill. The 
strength of the tree, destroyed by 
decay, has been restored by me- 
chanirally perfect Davey methods. 
The filling was put in by sections 
to permit the normal sway of the 
tree without cracking the filling, 
"he new bark is growing over the 
fdges of the filling and in time 
will cover it entirely. This tree 
is now in perfect b-alth — perma- 
nently saved — responding gloriously 
to the marvelous skill of Davey 
Tree Sui^ons who know how and 
^vhy.
