During this period of 36 years all the trees now 2nd class will become 
exploitable; and every year on the average more than 4,000 trees will 
reach maturity; and theoretically the true annual possibility of the forest is 
one-thirty-sixth of all the 1st and the 2nd class trees. But as we cannot work 
over all the forest every year, working up to this would entail cutting trees 
which are immature and capable of improvement, in the annual coupes, and it 
is at present considered wiser to restrict the number of 2nd class trees which 
may be utilised to one-fourth of the present stock, storing up the remainder 
to the enrichment of the forest and the benefit of the next generation. 
In the case of the sein, the 2nd class trees arc only half as many again 
as the 1st class trees, and during the first period the existing 1st class trees 
will amply supply the demand. 
The possibility is therefore calculated to be : —

A second example of a working plan drawn up on the same lines 
is that relating to the forests of the Inner Saraj Working Circle of 
the Kulu Division, Punjab.* 
The following are the trees to be considered in the Inner Sara] Working 
Circle : — 
First class 
over 2 feet in 
diameter. 
Second class 
over 1^' and 
np to 2' in 
diameter. 
Third class 
over 1' and 
up to 14'

Fifth class 6'' in
