Part II] Hole : Regeneration of Sal (Shorea robusta) Forests 65 
(33) Various objections to the proposed system are discussed and 
a modification of it is suggested for areas where scarcity 
of labour, or other difficulty makes it necessary to reduce 
the area artificially sown, as far as possible, see present 
paper, paras. 52, 53, 54. 
,(34) Finally, it is suggested that, in order to discover what modi¬ 
fications of the system are most suitable for any particular 
forest, a series of preliminary experiments should be carried 
out for two or three years in the forest in question. These 
experiments are detailed in the present paper, para. 56.
