126 AN AUSTRALIAN STUDY OF AMERICAN FORESTRY. 
SILVICULTURAL. 
12. Silvics and dendrology; silvical descriptions of forest types and 
species. 
13. Forest management—utilisation, cuttings, thinnings, and natural and 
artificial reproduction. 
14, Reafforestation—general problems. 
15. Forest influences—forests and climate, stream flow and erosion. 
16. Forest mensuration—critical analysis of forest measurements, and 
publications dealing with fundamental laws of the growth, comparative growth 
of different species, methods of working up field measurements. 
17. Wood structure and identification. 
18. Forest distribution. 
19. Cut over areas—study of. 
GRAZING. 
20. Improvement of range by seeding to cultivated forage plants. 
21. Improvement of range by natural reseeding—rotations. 
22, Studies of forage plants. 
23. Methods of handling stock—and other phases of the live stock 
industry related to efficient management of grazing lands on national forests. 
24. Range development—water and tracks, fences, and other improve- 
ments. 
25. Influences 2m re reproduction, floods and erosion, forest fires, and 
water supply. 
GENERAL. 
26. Forest manuals—preparation of. instructions governing the adminis- 
tration of the forests and the various branches of technical work involved. 
27. Scientific management in forest practice—time studies—elimination 
of lost motion—efficiency engineering. 
Forest Propucts. 
28. Mechanical, physical, and chemical properties of wood. 
29. Air-seasoning and artificial drying of wood. 
30. Agencies destructive to wood. 
31. Wood preservation. 
32. Wood distillation. 
33. Production of pulp, paper, gums, oils, dyes, and other chemical 
products of wood. 
34. New uses for indigenous species through wood preservation. 
35. Waste—and closer utilisation through improved methods. 
_, 36. Introduction of industries which will result in closer or more profitable 
utilisation, e.g., pulp and paper, wood distillation, turpentining, and the 
manufacture of secondary wood products. 
Many of these studies, of course, are being covered in a general way by 
the Forest Service as a whole, concurrently with its administrative work. and 
the activities of its specialised branches. , 
In the Office of Silviculture, for instance, the expert officers have under- 
taken a large amount of research work with regard to growths and vields 
reafforestation, and tree studies generally; while observations are being 
maintained on cut-over areas to determine the best methods of cutting and 
slash disposal for each type. =
