Relief must be provided anyway. It will be far better if the relief 

 can strike at fundamental causes and attempt the solution of national 

 problems than if it is confined to purely transient measures. Since 

 idle men can hardly be left to starve, it will be far better to put them 

 to work on constructive public works. Should it prove desirable 

 from the standpoint of relief the program can be carried out more 

 rapidly than indicated. 



Any attempt at national planning must provide for the recognition 

 of changing conditions. One of the essentials in forest land use is, 

 therefore, periodic revision of national plans such as here recom- 

 mended, perhaps as often as every decade. This will afford the 

 opportunity to consider not only the then existing conditions, but 

 also to take fully into account the more and more authoritative factual 

 data which it has been possible to accumulate, and the more and more 

 conclusive results shown by practical trials on a large scale of different 

 systems for meeting national objectives.
