 line. This limitation was removed in 1898 by resolu-

 was passed establishing fully the present Federal forest 

 policy. 



This law places the surveillance of all forest police 

 in all forests of Switzerland in the Bund, the private 

 forests as well as the public, i. e., State and communal 

 or corporation forests. But as there are distinctive dif- 

 ferences in the manner of this surveillance a differentia-

 be made by the cantons within two years. 



The forests are to be divided into protection and non- 

 protection forests, the former being such as are located 

 at headwaters or furnish protection against snowslides, 

 landslides and rockfalls, floods, and climatic damage. 

 Most of this segregation had already been made and 

 mapped in consequence of the law of 1876. 



All public forests are to be surveyed and their cor- 

 ners permanently marked by the cantons according to 

 instructions by the Bund, the latter furnishing the 

 needed triangulation survey, and inspecting and revising 

 any older surveys free of charge. 



The surveyed public forests are to be fully regulated 

 according to a sustained yield management under work- 

 ing plans made according to instructions by the Cantons, 

 to be sanctioned by the Bundesrath. Fdi* the unsur- 

 veyed forest areas at least a provisional felling budget is 

 to be determined, as nearly as possible representing the 

 sustained yield. In protection forests the working plans 

 must conform to the objects of these forests, and clear- 

 ings in these are as a rule forbidden. The fellings are
