primarily one of drought. The experiment was, therefore, continued 
to test this hypothesis as follows :— 
Sixteen pots of the same size as those used in the first part of the 
experiment were filled with loam brought from the local Lachiwala 
sal forest on July 4th, 1917. Of these pots, 1-4 were placed under the 
shade of trees and the remainder in the open in the Dehra Garden. 
On the surface of the soil a layer of dead sal leaves, 6 leaves thick, was 
spread in pots 1-8 inclusive, and 25 sal seeds were sown in each pot, these 
being placed on the layer of dead leaves in pots 1-8, and on the surface 
of the soil (not buried in the soil) in pots 9-16. After sowing, a layer of 
dead sal leaves 6 leaves thick was placed above the seeds in pots 13-16.

The pots marked* were lightly watered daily, the remainder 
were not watered and received the rainfall only. As germina¬ 
tion occurred, observations were made regarding the length of time the 
radicle remained healthy and when it blackened and withered, except in 
the case of the seeds covered by dead leaves which were only examined 
on July 20th after the leaves had been removed.
