line. This limitation was removed in 1898 by resolu- 
tion of the Council, and finally by 1902 a revised law 
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- 
tion of ownership conditions and forest conditions is to 
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. For 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
