3. The woods should be managed on sylvicultural principles, 
or 
and not in the park-like manner at present in vogue. 
. The operation of thinning should be conducted in a more 
rational manner, and with more regard to the future 
of the wood. (The more important principles of thinning 
are indicated in my paper on “The Importance of 
Density in Sylviculture,” published in the present part 
of 7’ransactions. ) 
. A broader view should be taken of the whole financial 
aspects of forestry. The success of forestry operations 
cannot be judged from the esthetic point of view, nor 
can it be gauged by the immediate returns; it can only 
be determined by the difference between the deferred 
or final sum of all the items of revenue and of ex- 
penditure. 
. Considerations of sport should be permissible only when 
they do not interfere with the production of timber, 
which is, of course, the main object of forestry.
