 conifers; effect of heavy thinning on ground vegetation; diseases and 

 injuries caused by fungi and insects, with special reference to wind 

 damage, nursery insects, and bark beetles ; study of forest soils, with

The board of directors of the Vladivostock Commercial School has 

 plans under way to transform the institution into a polytechnic school, 

 forestry being one of the subjects which it is proposed to introduce. 

 The board is seeking information in regard to the organization of 

 forest schools in the United States.
