For this, the thirteenth address and fourteenth meeting, the subject 

 of Forest Entomology in America has lieen chosen for at least two 

 reasons: (1) It deals with a different phase of the science, and (2) it is 

 a subject which will be taken up as a special feature of the work of 

 the Division of Entomology, United States Department of Agricul- 

 ture, after July 1, 1902. 



The primar}^ object will be to discuss some features of the study of 

 forest insects in America in a way which may be of service to the 

 student and yoiuig investigator, rather than to attempt to consider 

 the deeper problems for those of 3'ou who are alread}^ specialists in 

 other branches of entomology. 



While forest entomology has received more attention in some Euro- 

 pean countries, especially Germany, than has any other branch of the 

 science — and forest officials there are required to have special training 

 in the study of insect enemies and methods of combating them — it has 

 been comparatively neglected in America. Indeed, it has only been 

 within recent years that a sufficient need has been recognized to justify 

 giving it special attention. Great monumental works like those of 

 Ratze))urg of Germany, published in 1839-181:1:, together with the 

 rapid advancement at that time in systematic forest management and 

 government control of forests throughout Europe, inspired a great 

 interest in the su])ject, and led to a realization of the practical impor- 

 tance of a knowledge of insect enemies of trees in the successful man- 

 agement and protection of the forests. Therefore a knowledge of 

 forest entomology was early recognized in Germany as one of the 

 important features in the training of forest students and forest ofli-
