For this, the thii'teenth address and fourteenth meeting, the subject 

 of Forest Entomology in America has been 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 primary object will be to discuss some features of the study of 

 forest insects in America in a wa}- which may be of service to the 

 student and young investigator, rather than to attempt to consider 

 the deeper problems for those of you who are already specialists in 

 other branches of entomology. 



While forest entomology has received more attention in some Euro- 

 pean countries, especialh' 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 

 Ratzeburg of Germany, published in 1839-1844, 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 subject, 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 offi-
