Dear Mr. Davey: 
Please accept my sincere thanks for your 
most illuminating letter of October 3rd. 
Having read it, I find it easy to understand 
both how and why within a decade the 
Davey organization, from a “mere hand¬ 
ful,” has come to number upwards of three 
hundred intelligent, industrious, skillful 
workmen. 
Your story, interesting in itself, is most 
admirably told, though in its telling it 
appears to me that you have failed to 
mention the one element without which 
the “perfected methods, high type men and 
organization ideal” would not have come 
into being. That unnamed element I sus¬ 
pect to have been Davey, who first con¬ 
ceived the ideal, then determined the 
methods and later found and inspired with 
some part of his own enthusiasm the men 
who are actually carrying out the work. 
Shortly after receiving your letter I read, 
it to the department heads of the General 
Railway Signal Company,while at luncheon, 
and the interesting discussion that followed 
led me to show the letter to some of my busi¬ 
ness friends who are at the head of com¬ 
panies employing a great many men. In 
each such instance I have been asked for a 
copy of the letter—in order that they may 
have their men read and profit by it. 
I have not yet furnished such copies, 
though I would like to do so, believing that 
your story cannot fail to serve as an inspi¬ 
ration for both employers and employes who 
may be be privileged to read it. 
Will you have the goodness to write me 
at my home address whether I have your 
consent to make and send out to my 
business friends such copies? 
Sincerely yours, 
W. W. Salmon.

probably the most trying task con¬ 
fronted by a Tree Surgeon. The 
filling is subjected to tremendous 
twisting and strain; it must not 
only be held firmly in place by the 
most expert mechanical bracing, 
but it must also allow for the nor¬ 
mal sway of the tree. The section¬ 
al filling method aids wonderfully 
in this accomplishment, but cor¬ 
rect mechanical bracing is ultra- 
important. 
See the iron band around the 
trunk. The tree was splitting 
apart and a “tree patcher” tried 
to save it. Temporarily it pre¬ 
vented a catastrophe, but the 
band was strangling the bark. 
The real trouble, which was the 
decay on the inside, had received 
no attention whatever and the 
condition was growing rapidly 
worse. 
Davey Tree Surgeons got at 
the real trouble. They first tied 
the branches together with ropes 
to prevent accident while operat¬ 
ing. The decay was removed to 
the last particle, the inside of the 
cavity was thoroughly sterilized 
and waterproofed. The mechan¬ 
ical bracing employed demon¬ 
strates the finished skill and com¬ 
plete mastery of Davey Tree 
Surgeons. 
From Mr. T. De Witt Cuyler, Director 
Pennsylvania Railroad Co., 
Philadelphia, Pa. 
“Your work has been entirely satisfactory 
and I do not hesitate to recommend your com¬ 
pany to anyone who may desire similar work.” 
From Mr. Samuel G. Allen, Pres. 
Franklin Railway Supply Co., 
New York. 
“The work of your representatives on my 
place at Fair Haven is exceedingly satisfactory. 
I found your foreman not only a very capable 
operator but a very courteous and polite little 
gentleman." 
From Mr. Henry A Everett, Pres. 
Northern Ohio Traction and Light Co., 
Cleveland, Ohio. 
“It is now six years since you first treated 
my trees at Willoughby and I am more than 
satisfied with results.”
