Five typical letters 



from hundreds by 



satisfied Davey 



clients 



Mr. Geo. M. Verity, Pres. 

 The American Rolling 

 Mill Co., Middletown, 

 Oliio. 



"The work which your 

 men did on m.v prem- 

 ises has every evidence 

 of beinp: tirst class in 

 every respect." 

 Mr. T. W. Snow, Pres. 

 T. W. Snow Construc- 

 tion Co., Chicago, 111. 

 "The worl; which you 

 (lid at my place six 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- 

 bam Co., New York 

 City. 

 "I wish to express the 

 satisfaction we have had 

 in your work. The work 

 has been done in a thor- 

 ough manner and your 

 foreman and his assist- 

 ants are entitled to 

 great credit." 

 Mr. Wm. H. Grafflin, 

 Falston .Manor, Glen- 

 coe, Baltimore Co., Md. 

 **The work done at my 

 place has been done in 

 a very satisfactory way 

 and you are fortunate 

 in having such efflclent 

 and industrious em- 

 ployees, a refreshing 

 experience in these days 

 of carelessness and 

 shirking." 



Mrs. Cbag. 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 llv- 



A crude renipnt patch — inelTeotive and injurious 



Cement patch removed — showing extensive and 

 neglected decay 



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 treat- 

 ment 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, scien- 

 tific accuracy is not enough. Think of the terrific windstorm with its bend- 

 ing and twisting! You will then realize that Tree Surgery must be mechani- 

 cally perfect to withstand it. The mechanical principles and methods of 

 bracing employed by a real Tree Surgeon would amaze you 



Trees cannot be "patoned" like barn doors. 

 Men without long training and experience can- 

 not save them. Tree Surgery is a science unto 

 itself — a science demanding highly specialized 

 knowledge and remarkable skill for its success- 

 fulfill 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. 



Photograpli No. 1 illustrates a typical case of tree 

 "patching." To the untrained eye this work proba- 

 bly looks good, but a Pavey Tree Surgeon saw at a 

 glance that the conditions were bad. Growths of 

 fungus disease appeared along the edges of the fill- 

 ing and on the bark between the large and small 

 fillings. 



Photograph No. 2 shows the fllllng taken out. Nearly 

 every principle of the science of Tree Surgery had 

 been violated — the rough decay onlv had been re- 

 Tnoved; the cavity had not been disinfected: the con- 

 dition of decay behind this crude cement patch was 

 actually appalling, and the filling had only been In 

 two or three months; no bracing of any "kind had 

 been used; no means had been provided' to exclude 

 moisture; the large filling had been put in as a 

 solid mass, making no allowance for the sway of the 

 tree. 



Photograph No. 3 shows all decay removed by a 

 Davey Tree Surgeon; the cavity thoroughly disin- 

 fected and waterproofed; the mechanical bracing 

 partly in place; the watersheds cut to exclude mois- 

 ture. 



Photograph No. 4 shows the Davev filling completed 

 put in sectionally to permit swaying without break- 

 ing the filling. This tree has since stood through 

 many severe storms in perfect condition. New bark 

 IS now growing over the filling along the edges. The 

 tree has been saved permanently!
