APPENDIX. XIX 



' The whole process of the regeneration of a wood can there- 

 fore be divided into three stages : 



(a) Regeneration may be obtained without any felling of 

 the bverwood or cleaning of the underwood. There 

 is no evidence to show whether the excellent regenera- 

 tion which occurs in areas which have been heavily 

 felled over in the past was present before the fellings 

 were made or ensued as a direct consequence of the 

 fellings. But even if healthier seedlings are produced 

 under a light overwood and little or no underwood 

 it would still be inadvisable to open out the cover in 

 anticipation of a seed year. If a successful regeneration 

 year followed the fellings and cleanings immediately 

 excellent results might be obtained. But if no seed year 

 occurred for several years the exposed and fresh soil 

 would most certainly deteriorate and become stocked 

 with grass so that future attempts to procure regenera- 

 tion would be difficult. Since it is quite certain that 

 plentiful reproduction may be obtained under the most 

 adverse conditions of light the safest method of treating 

 unregenerated area is the maintenance of a complete 

 overwood and underwood and the burning of the leaf 

 layer. It may be also noticed that the overwood in 

 these selection forests is rarely dense but is generally 

 in a condition resembling that of a European over- 

 wood which is in the state of a light seeding 

 felling. 



(b) On the appearance of seedlings some degree of light should 

 be admitted by the removal of a portion of the under- 

 wood and overwood. It is very important that this 

 admission of light should be gradual since it has been 

 noticed that seedlings which have germinated and spent 

 their first growing season in shade tend to wither if too 

 suddenly exposed to direct sunlight.
