In the introduction the Author explains the task of Regulation 

 and the Normal Forest, defining Regulation about as follows : 



''Forest Regulation attempts to bring and to maintain order in 

 the management of a forest ; it regulates particularly the manner 

 and time of cutting the difiFerent stands of a forest ; it plans to 

 restock the land with new stands of trees ; and it determines the 

 amount of timber which may be cut each year without diminishing 

 the Wood Capital or endangering the continuance of such a cut for 

 the future." 



He adds: "The provisions of forest regulation are not em- 

 ployed for individual" stands of timber, cut at intervals of many 

 years, but apply to forests where a yearly cut of timber is possible 

 and demanded."
