In 1894 the forest law of Gotland, the cal- 

 Dangers careous island of Sweden, described on 



of p. 185, was amended to forbid the cutting 



Diameter of conifers below 8 inches diameter at the 



Limit. base. The result has been the opposite of 



advantageous, for, as a rule, the trees left 

 are suppressed, poorly developed runts, which had best been 

 removed ; true forest devastation has been the result. The new 

 forest protection law of Sweden, enacted in 1903, which required 

 the owner to replant if by the cut the regeneration had been im- 

 periled, did not improve matters. Owing to climate and inimical 

 conditions, with the forest once so deteriorated the difficulty of re- 

 establishing it by planting or natural regeneration is so great that 

 success by general prescription is rarely attained. 



A new law is proposed to establish a forest preservation com- 

 mittee, which is to supervise all cutting and make suitable con- 

 ditions fitting the particular case. The Committee is to employ 

 competent experts.

As is well known, in France conversions of 

 Timber Forest composite forest to timber forest have been 

 Production going on for some time (See F. Q. Vol. 



versus VI, p. 157 and 183). Viellard, a private 



Composite Forest, forest owner, brings a comparison of re- 

 sults in yield between three different stages 

 of development, showing the superiority of production of the 

 timber forest: 



1. French composite forest with few standards (160 trees), 

 no ha., 30 year rotation, net yield per hectar, 22.20 Mark. 

 181 ha., 25 year rotation, net yield per hectar, 21.68 Mark. 



2. Alsace stands, still in process of conversion. 



257 ha., with felling budget of 3.50 fm., net yield 28.16 



Mark. 

 86 ha., with felling budget of 3.23 fm., net yield 32.31 



Mark. 

 69 ha., with felling budget of 4.22 fm., net yield 40.10 



Mark.
