2. All unsound and malformed trees should be cut. 



3. As many first-class trees as possible should be cut as they no 

 longer have any quality increment. 



4. Advance growth should be favored. The presence of just a 

 little grass favors natural regeneration, but there must not be too 

 much. 



5. In mixed stands Beech should be cut out first, or else owing 

 to its rapid growth in youth it will crowd out the young Firs. 

 One or two trees per hectare (3 to 5 per acre) are quite sufficient 

 to produce a desirable admixture of Beech by natural seed re- 

 generation. 



6. Fellings should be repeated at regular intervals to avoid 

 stepped growth. 



7. Repair plantings of Spruce should follow immediately after 

 regeneration has failed. Silver Fir is not so suitable for planting, 

 owing to the slowness of its early growth and hence the amount 

 of grass produced, the higher cost of the young plants, and the 

 danger of being browsed by deer. 



Under these conditions a period of 20 years would be sufficient 

 for regeneration. 



In Wiirttemberg the silvicultural system is different. Here, 

 the stands are regenerated in strips, and fellings are not made in 

 favor of young growth unless it is within a distance of 30 meters 

 of the strip to be regenerated. The period of regeneration is 

 about 20 years. 



There is no doubt that this system is superior to the Baden 

 system* for stands in good condition, but care must be taken that 

 rotten trees are cut out of the stands not under regeneration, and 

 this has been neglected in some of the Wurttemberg stands in the 

 Black Forest. In fact in many places the percentage of rotten 

 trees is so high that no other system than the Baden system is 

 possible. 



8. The Pure Spruce Forests of the Black Forests. This type 

 extends over a very large area of the Black Forest but is more 

 generally found to the East or on the high undulating country on 

 the top of the Northern Black Forest mountains. 



*The two slopes of the Black Forest, like that of any other mountains 

 lying across the moisture bearing currents are climatically different : what 

 can be done in Baden is not suitable in Wurttemberg and vice versa. —
