132 AN AUSTRALIAN STUDY OF AMERICAN FORESTRY. 
Funds are allotted specially for the work. 
Control areas are constantly studied by the Forest Service with a view to 
making control measures increasingly effective by obtaining data on methods 
of attack and the history of-insect infestations, past and present. 
In view of the limited extent of our own timber resource, and the scope 
of the pest ravage within the forest, I recommend the adoption of a compre- 
hensive system of control. 
I propose the appointment of a forest entomologist and zoologist to under- 
take a systematic investigation of the forest pests. He should be stationed 
at the Forest Institute where his services would be available also in a section 
of the teaching work. Such measures as are evolved at the institute should 
be applied by the field staff to their forests. 
With regard to the overwhelming white ant infestations, it is possible that 
silvical measures may exercise far-reaching control influences. Apparently, 
white ants gain ingress to the tree either through a broken root or a broken 
branch. They follow the grain and cannot bore transversely. It is impossible 
for them to attack a sound tree. Consequently, it is the ancient and over- 
mature overwood which is most open to attack; the robust pole underwood 
escapes. 
A close well-grown stand cut before maturity is passed would probably 
be entirely free from white ant infestation.

THE FOREST WATER RESOURCE. 
It is true the water resource of our forests is infinitesimal in. comparison 
with that of the United States of America, but that fact should warrant the 
application of much more intensive control. 
“The United States of America Forest Service Manual” provides for the 
development of a definite water protection plan :— 
“Tn order to follow a definite and consistent policy with respect 
to the restriction of the use of the forest resources for the purpose 
of protecting the water supplies, complete information must be 
collected as to the sources, the amount, and use of water arising in the 
National Forests, the present condition of the vegetative cover on 
the watersheds, as to its influences or run-off and the special measures 
necessary to maintain the protective value of the cover. 
“This information will be presented in the form of a definite 
water protection plan. This will include an administrative map and 
report.” 
The administrative map shows the— 
“watersheds which supply water for municipal and domestic use, for 
irrigation, and for the development of hydro-electric power. It 
includes the location of ditches, corrals, flumes, dams, power plants, 
and other works; also the streams subject to disastrous floods and 
the settlements, mines, railroads, or other works in need of protec- 
tion from snowslides.”
