AN AUSTRALIAN STUDY OF AMERICAN FORESTRY. 45 
Every log must be numbered and the measurement entered against its 
number in the scaling book. Logs are measured generally in the standard 
16 feet lengths. 
In order to produce uniform methods of log scaling, a check scaler is 
employed to check the measurements of the other scalers who are required 
to approximate to his standards. Curves are prepared to show divergencies 
from the check scaling. 
Complaints are settled by a check seale. Additions in the scale book 
are checked in the supervisor’s office. 
Weekly cutting reports are submitted to the supervisor. These are com- 
pared with the timber sales record card for errors in entries brought forward 
from the last report and for correction of the rates. The total value of the 
cut to date is checked with the total deposits, to guard against cutting in excess 
of payments. 
A report of timber sold or cut is forwarded monthly to the district forester, 
who submits a similar report to the forester, giving quantities and values for 
each forest. 
Timber sales are divided thus— 
By amount— 
Class A—Ranger’s sales—not exceeding £20 in value. 
Class B—Supervisor’s sales—not exceeding £20 in value. 
Class C—Supervisor’s sales—exceeding £20 in value. 
Class D—District forester’s sales up to 30,000,000 feet. 
Class E—Forester’s sales over 30,000,000 feet. 
By advertisement— 
Unadvertised—Not exceeding £20. 
Advertised—Exceeding £20. 
Ranger’s sales and supervisor’s Class “B” sales may be made by estimate 
in lieu of appraisal. 
A maximum annual or periodic cut is fixed by the Minister for every forest, 
with a view to restricting the amount removed to the current production, i.e., 
a sustained yield basis; and also to conserve the supply of timber required for 
local use. 
The established limitations are reviewed annually by the district forester, 
but remain binding until changed by order of the Minister. 
It is the policy to increase the cut up to this maximum. Market surveys 
of each district are made, showing local consumption and sources of supply : 
and data on specific areas are furnished to possible purchasers, 
Forest supervisors and examiners (assessors) are required to make frequent 
personal supervision of sales. As far as possible this supervision is supple- 
mented by systematic inspection by members of the district office. 
A systematic record is made of the conditions of each sale area and the 
action taken by officers. 
A regular part of the administration is an intensive study of all cutover 
areas. The results of cuttings are checked as to windthrow, efficiency of 
protective measures, success of reproduction, and encroachment of brush, &c.
