widespread depredations by insects on the living timber previous to 

 the fire. In fact, the results of the investigations have clearly shown 

 that in the future successful management of American forests the 

 insect problem must rank with the tire problem, as well as with many 

 other problems which heretofore have received far greater attention 

 by expert foresters and the public. 



(3) Many of the problems which, on account of the losses involved, 

 demand special investigation, have been located, and much informa- 

 tion of practical value relating to them has been acquired. 



(4) The more important facts in the life history, habits, and prac- 

 tical methods of control relating to some of the more destructive in- 

 sects have been determined. 



(5) It has been demonstrated that some of the most destructive 

 enemies of American forests can be controlled with little or no cost 

 over that involved in ordinar}- forest management and business 

 methods if the expert information now available is properly utilized. 



(6) A mass of original data has been collected relating to forest 

 insects in general, including not only those which are destructive or 

 injurious, but those which are beneficial or neutral in their relation 

 to the forest, and represented by a collection of more than a million 

 specimens of insects and their work. 



(7) The accumulated evidence clearly indicates that the insect 

 damage to forest growth and manufactured commercial and utilized 

 forest products of the United States represents losses aggregating 

 more than $100,000,000 annually. 



(8) As a direct result of the investigation of forest insects (con- 

 ducted by this Bureau) during the past six years, at a cost of less 

 than $53,000, there has been accumulated a reserve fund of informa- 

 tion now available through publications, correspondence, and field 

 demonstrations, which, if properly utilized for practical application, 

 will evidently prevent a large per cent of the annual losses at a very 

 small cost. 



Practical Application 



The increasing interest in the subject of preventing losses from 

 depredations by forest insects manifested by owners of forests 

 and farmers' wood lots, and by manufacturers and consumers of 

 forest products throughout the country, also by the Forest Service 

 in its efforts towards the control of extensive depredations in the 

 National Forests, indicates that there is a quite general practical 

 application of some of the disseminated information and that there is 

 an increasing tendency to rely on expert advice as a guide to securing 

 the best results.
