PLANTING 169 



changes from place to place ; if, for instance, dry spots alter- 

 nate with swampy ground, the former may be sown on the 

 natural level or in ditches, while the latter necessitates sowing 

 on ridges. Where free soil alternates with stony or rocky 

 parts, the former may be sown in strips, and the latter in 

 patches or holes, etc. 



Section II. — Planting. 



By the term planting is understood in sylviculture the 

 method of forming a wood by means of plants which have 

 been raised elsewhere. The success of the operation depends, 

 as in direct sowing, on many matters, which hold good, more 

 or less, for the different ways in which the actual planting is 

 carried out. The business of raising the plants is in itself one 

 of great importance. Planting with slips, layers, etc., again, is 

 so different in many ways from the planting of seedlings, that 

 it will be considered separately. Hence, the subject now 

 under consideration may be divided into the following four 

 sub-sections : — 



A. Conditions of success. 



B. Piaising plants. 



C. Methods of planting. 



D. Planting of slips, layers, and suckers. 



A. Conditions of Success. 



This subject may be dealt with under the following 

 headings : — 



1. Choice of species. 



2. Different kinds of plants. 



3. Quality of plants. 



4. Age and size of plants. 



5. Season for planting. 



6. Density of planting. 



7. Distribution of plants over the area. 



8. Number of plants per unit of area.
