10. Forest products investigations, which include 
studies of the mechanical, physical and chemical properties 
of wood, wood preservation, pulp and paper-making, kiln- 
drying, seasoning, wood distillation, industrial statistics of 
the production, consumption and prices of forest products, 
mill-scale and depreciation studies. A comprehensive study 
of the lumber industry is being conducted by the Forest 
Service in co-operation with the Bureau of Foreign and 
Domestic Commerce and the Federal Trade Commission 
which aims to analyze in a constructive way the conditions 
in the leading forest-using industry of the United States, 
and to show their influence on the stability and advance- 
ment of the industry and on the conservation of the forest 
resources of the Nation. Other studies deal with the tech- 
nical phases of utilization and marketing and the re- 
placement of wood by other materials. 
11. Range investigations, which include studies of the 
carrying capacity of the national forest ranges, the natural 
and artificial reseeding of the range, improved methods of 
handling stock, methods of developing stock-watering 
places, eradication of poisonous and unpalatable plants from 
the range, the effect of grazing upon forest reproduction, 
the relation of grazing to erosion, streamflow and forest 
fires. This group of studies is especially important in 
the Intermountain Region where national forest range 
management is perhaps more important than in almost any 
other region. 
The Federal Government naturally assumes the leader- 
ship in forest research in the United States through the 
Forest Service. Out of a total annual appropriation of 
approximately $5,700,000, close to $375,000 are expended 
for research work in the groups just mentioned. This 
expenditure is admittedly necessary in order to lay the 
foundations for the practice of forestry, both on the 
national forests and elsewhere, for an increase in the 
productiveness of the forest resources, and for the econom- 
ical use of forest products. A well-equipped Forest Pro- 
ducts Laboratory is maintained by the Forest Service in 
co-operation with the University of Wisconsin at Madison,
