Reference is invited to what has been said in chapter I., 

 section I. of Part II. In addition it remains to be men- 

 tioned, that planting is admissible in the case of all species, 

 and that it is specially adapted for those which are tender 

 during earl}- youth, and which cannot receive sufficient atten- 

 tion and protection in direct sowings on a large scale ; also to 

 species the seed of which is expensive, or exposed to dangers 

 from animals, 



2. Dift'i'i-rnt Kinds of Planta. 



The plants used in sylviculture are of many kinds, according 

 to external form, origin, age, etc. No general classification is 

 possible, since the various groups overlap each other. For 

 practical purposes the following divisions will prove useful : — 



A distinction must, in the tirst place, be made between 

 plants which have sprung directly from seed, and those which 

 formed part of an already existing individual ; hence the 

 division into : — 



(1.) Seedling plants. 



(2.) Suckers, layers, or cuttings. 



All woody plants can be successfully raised from seed, but 

 only certain species from suckers, layers, or cuttings. 



Hooted plmits are distinguished from plants irithoitt mots. 

 Seedlings, suckers, root cuttings, and layers when they have 

 become independent individuals, are rooted ; cuttings taken 

 from the stem or branches are without roots at starting, but 

 they may i)econie rooted by placing them in a nursery before 

 putting them out into the forest.
