Preparing Working Plans. 157 



ary plan for a national forest has yet been made. When one of 

 these has proved practical after several years use, it is time 

 enough to talk of final plans. 



The system of annual and preliminary plans and other data, 

 described above, has not been put into actual practice. If plans 

 on this basis are attempted a great many stumbling blocks will 

 probably be encountered and during the progress of the work 

 numerous changes may be necessary. It is believed by the writer, 

 however, that the general scheme is sound, and that by following 

 it a practical form of forest management may be established for 

 the National Forests. 



The writer intends this article to stimulate discussion on this 

 very interesting, yet most difficult of the problems which the Fed- 

 eral Forest Service has to solve.
