A GRE^T WORK 



IN WHICH ^LL SHOULD 



The Tree Doctor was first published with a view of correcting "Tree 

 Troubles" in Cleveland, O. It has practically revolutionized tree culture 

 in that city. It is the photographic work that makes it affectual. Since 

 its appearance, the author of the work has been called in all directions to 

 inspect trees, and now makes the alarming declaration that not more than 

 ten per cent of trees are sound ! To help arouse the country to the serious- 

 ness of the situation, he has invested in a stereoptican lantern, and, by the 

 use of some 200 photographs, is enabled to let people " SEE" what is the 

 trouble. Nothing in the lecture field has proved so educational. It should 

 be presented as fast as possible all over this broad land. Those desiring the 

 lecture, should communicate with John Davey, Kent, O., in order to arrange 

 for dates, etc. 



The following letter is a sample of the many favorable testimonials 

 given. 



SHARON, PA., FEB. igth, 1904. 

 To Whom it may Concern : 



At the request of the Civic Committee of the Sharon Board of Trade 

 Mr. John Davey, author of " The Tree Doctor" gave a stereoptican lecture 

 in the Presbyterian Church, Sharon, Pa. on the evening of January 21, 1904, 

 showing in an excellent manner on canvas the destructive way in which our 

 trees are being butchered and also the means for remending the trouble 

 and thereby preserving their life and beauty. Mi. Davey's lecture was 

 repeated the following evening for the special instruction of the school 

 children. 



We most heartily commend Mr. Davey in his laudable effort to 

 awaken public sentiment for the better preservation of trees and shrubbery 

 and believe that by a more general dissemination of the information given 

 in his lecture and also contained in his book "The Tree Doctor" that pub- 

 lic spirited citizens everywhere will be glad to see that their trees have 

 better care in the future than they seem to have had in the past.
