88 AN AUSTRALIAN STUDY OF AMERICAN FORESTRY. 
If the listing will seriously interfere with or hamper the administration, 
protection or use of the National Forest then the listing is injurious. 
“Tt is useless to administer a forest if it cannot be protected. It is 
equally useless to administer and protect if it cannot be used. It follows, 
therefore, that not only is it necessary to retain such areas as may be 
required to protect and administer the forest, but it is also necessary to retain 
such tracts as may be required for the practical use of the surrounding forest 
areas.” 
Exploitation requires mill sites, camp sites, banking grounds, logging 
roads, chutes, &c. It is necessary to maintain “ practical grazing units, corrals, 
watering places, lambing and round-up grounds, stock driveways, and holding 
grounds.” 
Water power development in the National Forests necessitates holding 
rights of way for reservoirs, dams, canals, &c. 
Finally, proper administration demands the retention of “areas needed 
for ranger stations, pastures, lookout stations, roads, trails, telephone lines, 
planting or nursery sites, firebreaks, and every other area needed in the work 
of the forest officer—and such areas needed for public camping grounds, 
health or pleasure resorts, or other purposes for the use of the public. 
In the enforced hurry of classification in the Australian States, the 
importance of many of these issues often has been overlooked, and adjust- 
ments must continue for years beyond dedication,-involving resumption and 
purchase. There has been no preliminary forest plan “ without first carefully 
studying which no forest officer should attempt to classify the land in a forest.” 
The elimination of agricultural land in the United States of America is 
done in conjunction with boundary revision. Ths procedure is laid down for 
a systematic plan of classification, comprising the following lines of work :— 
(1.) Boundary revision. 
(2.) Extensive examination of areas for which data is available, 
showing few agricultural possibilities and overshadowing 
timber or watershed values. 
(3.) Intensive examination of areas believed to have considerable 
agricultural value and doubtful value for timber or watershed 
purposes. 
(4.) Examination of small areas upon individual application to avoid 
the delay of waiting until reached in the progress of the 
regular classification work. 
An extensive classification forms the basis of the system. Ali written 
and unwritten information which the service and its officers have already 
secured is correlated and combined in a report by a forest officer who should 
have broad experiences, liberal ideas, and extensive general farm experieice 
or who should be assisted by the direction dnd advice of an experienced agri- 
culturist familiar with the general farm practice of the region. 
The report covers :— 
(1.) Value and importance of the forest as a sound timber supply and 
need of retaining it for timber production. 
(2.) Value and importance of the forest as a watershed and need 
of retaining it to preserve the natural cover for the regulation 
of stream flow.
