76 JOURNAL OF FORESTRY 



In forest management 18 experiments with 13 sub-projects are 

 under way to determine the best methods of cutting in different types 

 of mature timber ; of securing natural reproduction, 22 ; the value and 

 practicality of thinnings in immature stands, 14; and the methods of 

 brush disposal which will reduce the fire hazard and permit the estab- 

 lishment of young growth at a reasonable cost, 6. 



The management of farm woodlands is the subject of three projects. 

 A single study of pruning may be mentioned here. 



Forty-eight studies are being made in forest measurements, 13 on 

 volume, 6 on yield, and 29 on growth. 



Fourteen projects may be classed as studies of forest types or of 

 forest ecology. Nineteen deal with as many individual tree species, 

 their characteristics and life histories. 



The protection of the forests includes 57 projects, of which fire has 

 13, fungus diseases 11, insects 30, and other factors 3. 



Studies of the grasses and forage plants in the forests are leading 

 to the proper use of this secondary forest resource for the production 

 of cattle, sheep, horses, and goats. A total of 29 experiments are in 

 progress to determine the number of stock the range will support, the 

 best method of reseeding depleted range, of handling stock, of develop- 

 ing watering places and of eradicating poisonous plants. One organiza- 

 tion lists seven projects in forest zoology which are only indirectly 

 related to the general subject of forest research. 



Well-equipped laboratories are investigating the structure, mechan- 

 ical and physical properties of woods, including 43 projects; methods 

 of kiln drying and of preserving forest products by the use of chem- 

 icals have 24 projects; the construction and uses of laminated wood 

 products, 5 projects ; suitable species and improved processes for the 

 manufacture of wood pulp and paper, 9 projects; the preparation 

 and utilization of the products of destructive distillation of the different 

 woods, and the methods and species best adapted to the production of 

 turpentine and rosin, 19 projects; and the prevention of depreciation 

 and decay due to insects and fungi, 9 projects. 



Economic and industrial investigations include in all 62 studies. 

 Eleven are on the uses of various woods for vehicles, for railway cars, 

 for shipbuilding, etc., as well as the uses to which given species of 

 wood are best adapted. Logging and lumbering methods and costs 

 and lumber grading are the subjects of 10 projects. The possibilities 

 of reforesting logged-off lands, the classification of land, forest policy
