In addition to the maximum possibility as calculated by Brandis’ 
Method, it is evidently permissible to re- 
Example II. All sound I move all unsound trees of the second and 
Class trees unsound II , , i, i ,i , 
Class trees. lower classes, as well as such other trees 
of these classes as it is calculated will for 
various reasons never attain exploitable dimensions. 
The following example illustrating the first case is instructive 
as showing not only the manner in which the removal of the unsound 
Class II trees may be prescribed, but more especially the method in 
which a forecast of the condition of the crop at the conclusion of the 
fellings may be calculated.* 
Owing to the forest being in such an abnormal condition and to the great 
number of unsound trees, it is proposed for the first felling rotation to cut over 
all the Class I teak and the unsound trees of Class II by the selection method. 
The period proposed for this felling rotation is 40 years, or about two-thirds 
of the time it takes a Class II teak to become Class I. 
From the valuation surveys it is estimated that the present stock of teak 
is as follows : —
