Part II] Hole: Regeneration of Sal (Shorea robusta) Forests 41 
(2) Owing to the less vigorous and slower growth of the seedlings, 
the weeding must be continued longer. 
(3) A considerable proportion of the area is not stocked with 
seedlings. 
(4) When the standing trees are eventually felled, the young growth 
is liable to be damaged. 
Summary of conclusions , 
42. The following conclusions appear to be justified by this experi¬ 
ment : 
(1) A layer of dead leaves on the ground is very injurious to germi¬ 
nation and seedling development, see para. 41 (2). 
(2) In order to get good results uniformly and quickly, hoeing is 
necessary, see para. 41 (3). 
(3) Sowings with the overhead cover intact result practically in 
failure, see paragraph 41 (4). 
(4) - Sowing after interrupting the overhead cover gives results much 
inferior to those obtained by sowing on a cleared strip 60 
feet wide, see para. 41 (5) (7). 
(5) Broadcast sowings under forest conditions, on hoed soil, without 
fencing of any kind, with one weeding in the first year and 
two in the second year, on a cleared north-south strip 60 
feet wide (this width being about § the average height of 
the surrounding trees), have given 25 per cent, surviving 
seedlings after 1J years, with an average annual height-growth 
of 8 inches. This would give established seedlings approxi¬ 
mately 3^ feet high in 5 years, see para. 40. 
(6) Similar sowings on a cleared north-south strip 100 feet wide 
(this width being about 1J the average height of the surround¬ 
ing trees) have given 10 per cent, surviving seedlings after 
1J years with an average annual height-growth of 9 inches. 
This would also give established seedlings approximately 
3^ feet high in 5 years, see para. 41 (6). 
(7) Side-shade from the south in a year of heavy rainfall is decid¬ 
edly injurious to the development of sal seedlings, see para. 
39. 
Experiment No. VIII. 
Object to determine the effect of sowing in the open in a season unfavourable 
for germination. 
43. The experiment recorded below is interesting, since it indicates 
the results likely to be obtained by broadcast sowings in a cleared patch 
in a season unfavourable for germination and early growth, with an 
unusually short rainfall at the end of June and in July.
