Part II] Role : Regeneration of Sal (Shorea robusta) Forests 37 
a-c, commencing from the north. The treatment of all the areas was 
precisely the same, viz. :— 
Area (a). A layer of dead sal leaves, 6 leaves thick, was laid on the 
surface and the seed sown broadcast on the aead leaves. 
Area (b). A layer of dead sal leaves, 6 leaves thick, was laid on the 
surface and then burnt off, the seed then being sown broad¬ 
cast on the soil surface. 
Area (c). A layer of dead sal leaves, 6 leaves thick, was laid on the 
surface and then burnt off. The soil was then dug and 
the seed sown broadcast on the dug soil. 
In Plots XVII, XXV and XXVI, each separate area (a) (b) and (c), 
respectively, measured 20 feet from east to west X 15 feet from north 
to south. In Plot XVIII, each separate area (a), (b) and (c), respect¬ 
ively, measured 40 feet from east to west and 15 feet from north to 
south. The digging in all cases consisted merely of rough hoeing with 
a 'pharwa, similar to the work carried out in tea-gardens. All natural 
seed falling on the areas was removed before sowing commenced, as 
well as all existing seedlings. 
The leaf-fall of 1918 was brushed off in June 1918, and the natural 
seed falling on the areas in June-July 1918 was also removed. The 
areas were weeded in October 1917, June 1918 and at the end of August 
1918. In sub-plot IV of all the plots, which received heavy shade from 
the south, the results were uniformly bad, thus indicating that, in a 
year of heavy rainfall, side-shade from the south is decidedly injurious. 
In the period June-September 1917 the rainfall was 102 inches as com¬ 
pared with the normal 75 inches.

plots is given below :
