In Appendix D of the working plan report details by compartments are 
given, and the method of calculation is explained. 
The following remarks may be noted : — 
(a) Girth-percentages .—It is assumed that the trees in each class pass 
up into the next higher class as follows, within the average periods given in 
paragraph 44 : —

(b) There is good reason to suppose that the enumerations of 1891-92 
and 1893-94 gave too large figures. The numbers of exploitable trees based on 
them as given in the working plans have not always been found.

The fairly close correspondence between the numbers in Class I and dis- 
parity between those for Class II are noticeable. For this reason, in the cal- 
culations of stock now made, the 1891-92 and 1893-94 figures for Class I and 
the 1886-87 figures for Class II have been adopted!, and no allowance is made 
for growth in Class II in the interval between the enumerations. 
The following table shows the stock of sal per acre in compartments 27 
and 33 in 1885-86, as calculated therefrom for 1902-03 and as actually enumerated 
in 1901-02, respectively —
