INTRODUCTION. 



is/to 



The original Tree Doctor, notwithstanding its crude form, 

 started a revolution in tree culture in the United States and 

 Canada. Since the first edition has been exhausted, urgent calls 

 have come for a second. In answer to these demands, I have re- 

 vised the work and now issue -it with the following improve- 

 ments : 



First 213 photographs, all of the finest quality. 



Second Photographs generally explained by notes contiguous 



to them. 

 Third Tree surgery described and illustrated in few and simple 



words. 

 Fourth "Pear Blight" and other "Blights" not^a disease, but 



the result of injuries, the source of disease. 

 Fifth Cause of "Peach Yellows" The far-removal of trees 



from their native environments. 

 Sixth Grape culture made simple. 

 Seventh A splendid collection of flower photographs. The 



way to grow them. 



Eighth Special illustrations of vines. How to procure them. 

 Ninth Native forests, their destruction, the significance, 



remedies. 



Tenth K elation between trees, birds and insects. 

 Eleventh Numerous photographs illustrating "stiff" and "free" 



landscaping. 

 Twelfth Twenty formulas for the destruction of insects. 



This work is sent forth with a fervent prayer for Heaven's 

 blessing on it, and an appeal to all to help in planting and caring 

 for trees in the country that was once pre-eminently "The Land 

 of Forests."
