CH.VHI REGENERATION BY SEED 221 



selection method, as it is really an enlargement of the 

 same method. In a mixed forest it will probably be 

 the most suitable, as the regeneration can be started 

 at various points according to the requirements of 

 the component species. In hilly countries the strip 

 method may give better results if carefully conducted, 

 and the compartment method might be employed with 

 success with pure forests of light-demanding species. 



A thorough knowledge of the species and their 

 individual requirements, of the locality and climate, 

 of the capabilities of the forest staff, and of the laws of 

 supply and demand, is required before any particular 

 method of high-forest treatment is finally adopted ; and, 

 until then, the selection method will be found to be the 

 safest. 



In comparison with the system of coppice the high- 

 forest treatment fulfils other objects. It is more 

 generally devoted to the production of large timber, 

 while the coppice treatment is intended to supply, in as 

 short a time as possible, small wood such as is required 

 for firewood, the manufacture of charcoal, etc. It is true 

 that coppice under standards combines both objects, 

 but it rarely produces as fine timber as that obtained 

 from high forest, because the surrounding trees are felled 

 several times during the life of the standards, which thus 

 rarely attain the same length of bole as trees in high 

 forest, and the repeated exposure of the boles to direct 

 sunlight leads to the production of much more uneven 

 grain in the timber. At the same time, the repeated 

 exposure of the soil by successive coppice-fellings leads 

 to a deterioration of the soil which maybe temporary only, 

 but which, nevertheless, has some effect on the vigour of 

 the trees.
