ch.ix COMBINATION OF SYSTEMS 225 



teak forests of Burma, for example, which are worked 

 on the selection method, the dibbling in of teak seed is 

 strongly advocated ; but where the mixture of teak in 

 the upper tier is scanty, temporary cultivation is per- 

 mitted in many places with a proviso that the cultivators 

 sow teak or some other prescribed seed with their 

 crops. After an interval of some years of cultivation, 

 the area is again taken over by the Forest Department 

 with a young crop of teak or Acacia Catechu as the 

 case may be. Fig. 76 shows a case of teak being intro- 

 duced in cleared lines in a Ceylon forest. 



In simple coppice and coppice under standards it 

 may happen that the stools become too unhealthy to bear 

 vigorous shoots, or that they may die. Although I do 

 not know of any case in the Tropics where these have 

 had to be renewed by putting in plants, this procedure 

 is not unfrequent in European forests where strong 

 plants are put in, capable of being able to maintain 

 themselves in the midst of coppice-shoots. Plants may 

 also be put in to be ultimately reserved as standards. 



The employment of artificial regeneration, either as 

 a substitute for or in conjunction with natural regenera- 

 tion, will naturally depend on the time which the forester 

 has for obtaining complete regeneration on the species 

 which already exist in the standing crop, on the funds 

 and labour which he has at his disposal, on the demand 

 for certain species, and on the capability of supplying it 

 with or without artificial aid. With the large areas in 

 the Tropics, which are in urgent need of scientific 

 management, the amount of assistance given hitherto to 

 natural regeneration by means of sowing and planting 

 has been necessarily small. Other measures, which are 

 even more necessary and urgent, have taken up most of 

 the time and available funds at the disposal of the 

 forest officer.
