The new facts determined during recent investigations in Caiitornia, 

 Oregon, Wasiiington, and Idaiio relating to the habits of the destruc- 

 ti\'e enemies of the redwood, Monterey pine, Western yellow pine, 

 sugar pine, Jeffer}' pine, shore pine, mountain pine, and lodgepole 

 pine, and the Western hemlock, Douglas spruce, Englemann spruce, 

 several species of fir, the Western larch, and Western cedars, have made 

 available a fund of information which will be of special service in 

 future studies of the enemies of the principal forest trees of the West- 

 ern forest reserves. 



The extent and magnitude of depredations by insect enemies of the 

 forests and forest products of this country; the comparatively meager 

 knowledge of the essential features in the life history, habits, and 

 natural enemies of the principal depredators on which to base con- 

 clusions relating to methods of control or prevention; the possibility, 

 as has been demonstrated, of future detailed investigations leading to 

 the discovery of methods of preventing a large part of the losses; the 

 facilities aiforded in the extensive Government reserves and in large 

 private areas where systematic working plans and forest management 

 have been adopted, together with the information available from the 

 results of investigations in this country and Europe, seem to warrant 

 the recognition of forest entomology as a distinct branch of economic 

 science. 



The address was most heartily received, and, on motion of Mr. How- 

 ard, Mr. Hopkins was voted the thanks of the Association for his able 

 presentation of this very important subject. The discussion of the 

 address was postponed until the opening of the afternoon session and 

 the regular business of the association was taken up. The discussion, 

 however, is here inserted in connection with the address for the sake 

 of continuity. 



Mr. Smith stated that he had been much impressed by the address. 

 He thought the subject one of the most important in its waj- in the 

 U nited States, and the presentation of much value to entomologists. 

 He knew that there was much injury done to forest trees by insects, 

 but some things in the address impressed him as being contrary to his 

 own experience, especially the statements about the giant root-borer 

 {1'ri.iinmlaticoUk). In his experience, though that insect appeared 

 quite generally in oak forests, he had not found it in that tree. 

 According to his observation an old pine log was almost certain to 

 become infested l)y the larva and to become its home. He had a large 

 amount of material showing this. The line of work followed by him 

 was quite different from that followed by Mr. Hopkins, and he would 

 place the damage done by forest fires far ahead of that done by insects. 

 Mr. Smith considered that in New Jersey the insects followed the
