Five typical letters 
from hundreds by 
satisfied Davey 
clients 
Mr. Geo. M. Verity, Pres. 
The American Rolling 
Mill Co., Middletown, 
Ohio. 
"The work wliirh your men 
did on my premises has everj' 
evidi'tice of being first class in 
everj' respect." 
Mr. T. W. Snow. Pres. 
T. W. Snow Construc- 
tion Co., Chicago, III. 
"The work which you did at 
ray place sLx or seven years 
ago is so satisfactory that I 
have not found it necessary to 
do anything more. Every tree 
you treated, including the 
worst ones, have since that 
time made new and beautiful 
trees. ' " 
Mr. Edward Holbrook. 
President, The Gor- 
ham Co., New York 
City. 
"I wish to express the satis- 
faction we have had in your 
work. The work has been done 
in a thorough manner anil your 
foreman and his assistants are 
entitled to great credit." 
Mr. Wm. H. Grafflin, 
Falston Manor, Glen- 
coe, Baltimore Co., 
Md. 
"The work done at my place 
has b:en done in a very satis- 
factory way and you are for- 
tunate in having such efficient 
and industrious emp'oyecs, a 
refreshing i xperience in th"s ■ 
days of carelessness and shirk- 
ing." 
Mrs. Chas. G. Weld, 
Brookline, Mass. 
"I am very much pleased with 
the result of your work on my 
trees. . . From their 
present appearance I do not see 
why they should not last many 
years longer, whereas last year 
we had grave doubts as to 
their living." 
THE tree is a living organism; it breathes, assimilates food, has a real circulation. 
Its normal condition is health, but it is subject to disease and decay just as any 
other living thing. 
As with one's body or one's teeth, the tree responds only to that treatment which is in 
scientific accordance with Nature's laws. 
The physician, the surgeon, or the dentist requires years of patient study, plus the 
intuitive skill born of ripe experience, before he is equipped to obtain successful results. 
This is also exactly true in Tree Surgery. However, in Tree Surgery, scientific accuracy 
is not enough, think of the terrific windstorm with its bending and twisting! You 
will then realize that Tree Surgery must be mechanicall)- perfect to withstand it. The 
mechanical princi])les and methods of bracing emplo}-ed b}- a real Tree Surgeon would 
amaze vou. 
Trees cannot be "patched" like barn doors. Men 
without long training and experience cannot 
save them. Tree Surgery is a science unto 
itself — a science demanding highly specialized 
knowledge and remarkable skill for its success- 
ful application. 
Facts little understood 
Because the facts set forth above have not been 
understood, great injury has been done to thou- 
sands of trees everywhere and a vast amount 
of money has been wasted in disastrous tree 
"patching." 
It has been the fault of nobody in particular. 
Tree owners simply have not realized the de- 
gree of scientific knowledge and mechanical 
skill required in the permanent saving of 
trees. And "tree patchers" — the men who have 
been doing the faulty and dangerous work — 
are in many cases conscientious enough, but 
ignorant of the facts and lacking in skill. 
P/.oto^rap'i No. I illustrates a typic I case of tree 
"ijatchiiig." To the ui-.trained eye this work prob- 
ably looks good, but a Davey Tree Surgeon saw at 
a glance that the conditions were bad. Growths of 
fundus disease appeared along the edges of the filling 
and on the bark between the large and small fillings. 
Photograph No. 2 shows the filling taken out. 
Nearly every principle of the science of Tree Surgery 
had been violated — the rough decay only had been 
removed; the cavity had not been disinfected; the 
condition of decay behind this crude cement patch 
was actually appalling, and the filling had only been 
in tvvo or three months; no bracing of any kind had 
been u=ed; no means Ind been provided to exclude 
niotsture; the large filling had been put in as a solid 
ma=^, inakinff no allowance for the sway of the tree. 
P^ctcjaph No. 3 slfows all decay removed by a 
I )a\cv Tree Surgeon; the cavity thoroughly disin- 
fected and waterproofed; the mechanical bracing 
partly in place; the watersheds cut to exclude mois- 
ture. 
Plotograph No. 4 shows the Davey filling com 
pie ted, put in sectionally to i>ermit swaying without 
breaking the filling. This tree has since stood through 
many <^evere storms in iierfect condition. New bark 
i*^ now growing over the filling along the edges. 
The tree has been saved permanently!
