The following rules should be observed during girdling operations : — 
(1) Except when it is necessary to retain them as seed bearers, unsound 
trees that will yield a log of marketable timber must be girdled. 
These trees do not form part of the annual yield of 1,000 sound 
trees and must be kept in a separate list. 
Unsound trees may be considered to be those which contained a dis- 
tinct cavity, near the ground or high up, or have their heartwood 
exposed to a height of at least 6 feet from the ground, and round 
at least half the diameter of the tree, or have had the top of the 
main stem broken off by wind. 
(2) Except when it is necessary to retain them as seed bearers, the 
crowns of the trees being sufficiently free to bear seed, all trees 
attacked by ficus must be felled. 
(3) Trees which have reached a girth of 6 feet and are growing in 
localities where it is evident that they ■will probably not reach a 
girth of 7 feet and remain sound must be girdled if they contain 
marketable timber and are not required as seed bearers. 
Such trees occur principally in compartments 1 to 10, 13, 16, 20, 21 
and 22, and the girdling officer will have no difficulty in deciding 
which are to be girdled. 
(4) Isolated sound trees must never be girdled during the first period. 
(.')) Marketable trees, if quite sound and of good shape and growing close 
to the main streams, or in other localities where extraction is 
easiest, must not be girdled. 
An estimate based on the figures in paragraphs 52, 53 and 54 of the larger 
sizes of the growing stock in 1938 is as follows : — 
Class I, 50,199— 32,000:=-- 18,199. 
Class II, I?- of 29,938 =21,336. 
Class III, /y of 29,938 -f || of 50.869 + of 37,728 = 57,277.
