a figure which is also near the others (already given above). This similarity, it is 

 interesting to note, allows one to conclude that the production of the forest of 

 Chamonix is in the neighborhood of 4,500 cubic meters and that in fixing the yield at 

 3,018 cubic meters there will be an annual saving of about 1,500 meters. This economy, 

 which is really an enrichment of the stand, is fully justified and is in perfect accord 

 with the wishes of the officials." 



The American professor of management could easily pick flaws in 

 this working plan. To start with, he might argue that the same normal 

 stand should not hold for all soils, species, mixtures, and altitudes; 

 that Pressler's method is not exact; that the decrease in the number 

 of trees is not fully known, and so on. But what impresses me most is 

 the simplicity of the plan, its evident practicability, its freedom from 

 ponderous descriptions which are replaced by tables and curves showing 

 at a glance what the administrator must know. No two plans are 

 exactly alike. Where there is a "Chief of Management" stationed in a 

 district, they have no cut-and-dried air. Some of the methods are far 

 too intensive for the United States, but it is believed the review contains 

 suggestions which may be of value to the profession. There is practi- 

 cally no difference in the important details between an original plan and 

 a careful revision. As a matter of fact, the methods could be followed 

 very closely in a forest where intensive management had to be applied 

 such as on a small estate. It is no wonder that M. Schaeffer is recog- 

 nized as the foremost working plan expert in France.
