CHAPTEE II. 



FORMATION OF WOODS. 



THE formation of a wood comprises all sylvicultural 

 measures having for their object the production of a new 

 crop of trees. Such a crop can spring up from seed, 

 slips, layers, pieces of roots, or from stool shoots and 

 root suckers. In some cases the formation of a new 

 crop is the result of the spontaneous action of nature, in 

 which case the forester speaks of natural formation or 

 regeneration, in others the seed or seedlings are brought 

 on to the land by the action of man, when the pro- 

 cess is called artificial formation. A further distinction 

 must be made as regards the special kind of material 

 employed for the formation of a wood. Again, two or 

 more methods of formation may be combined. Finally, 

 a wood may be composed of a mixture of two or more 

 species. Accordingly, the matter to be dealt with in 

 this chapter has been arranged under the following 

 sections : 



I. Artificial formation, or sowing and planting. 

 II. Natural regeneration through seed, shoots and 

 suckers. 



III. Choice of method of formation. 



IV. Formation of mixed woods.
