FUTURE YIELD. 
The policy of the owners and the condition of the forest combine to 
render considerations of future yield of very minor importance in the 
preparation of this working plan. From the standpoint of the owners, 
the feasibility of management depends neither on securing a sustained 
yield for an established mill nor on the certainty of being able to 
realize a profitable return on the capital invested in the land, but on 
the possibility of securing more in the long run under management 
than without it. From the standpoint of the forest, the first and for 
the time being almost the only question is, not how soon it will pro- 
duce a given amount of timber at its present rate of growth, but how 
it can be made to produce its full yield. The problem presented on 
these lands is the management of a forest in poor condition as the 
result of maltreatment, together with the utilization of the merchant- 
able timber which it contains. The management advised is based,
