Four experiment stations for the intensive study of silviculture 

 have been established on National Forests. Aside from these sta- 

 tions an enormous amount of investigative work has been in- 

 augurated, in reforestation, yield, results of various methods of 

 cutting, and other fundamental aspects of silviculture. An office 

 of grazing studies has been established. Its work, already begun 

 in several districts, will be rapidly extended. 



To get the best results all of these activities must be unified. 

 Duplication must be avoided. Each investigative project must be 

 undertaken by the unit, or the station, or the men best qualified to 

 handle it. Where several men in different districts or branches 

 of the Service should co-operate in a study, the part assigned to 

 each must be carefully mapped out. Plans must be fully matured 

 and checked, to make sure that the most important problems are 

 attacked in the right way and that all of the available information 

 and facilities of the Service are utilized. 



The investigative committees are designed to assist in these 

 ways. They are not to hamper or check the individual member 

 of the Service, but to aid him by correlating his plan and efforts 

 with those of all the other members. 



The publication of the "Review of Forest Investigations" from 

 time to time will be an important factor to the same end. It will 

 aim to keep all of the men engaged upon investigative work in 

 touch with each other. It will give them the fresh results of each 

 study as it developes. It will be primarily for the interest and 

 benefit of all the investigators in the Service, in all lines of its 

 work, as a cumulative medium for interchange of scientific data 

 and ideas. 



At a conference in Spokane, in December, between officers of 

 the University of Idaho and timber owners belonging to the 

 North Idaho Forestry Association, it was unanimously decided 

 to pro-rate the timber holdings of the members, in order to raise 

 funds for the erection of a Forestry Building for the University, 

 to cost v$58.ooo. Prof. C. H. Shattuck of the University gave an 

 address on Utilization of By-Products.
