petals, and the naked surface of the seed of the tree-cotton 
were dominant characters. This is so far interesting as the red 
colour of the leaf-stalks and the nakedness of the seed, were 
dominant also in totally different crosses between two Indian 
races, 
The seeds were all sown in ny garden in September 1904, 
and the Indian varieties came into flower two months later. 
The loeal races—Northerns Bilaihathi Jowari and Yerrapathi— 
had been grown for some years on the Government farm at 
Bellary, and might be considered pure. The ten or twelve plants 
in each bed appeared to be very similar. But among the Jar 
and the Bani, from the Central Provinces, were two plants having 
large yeliow instead of small white flowers. Attempts to cross 
the two kinds of Bani—the yellow and the white flowered—were 
not successful, but the yellow flowered Jar? was crossed with 
other plants. (Table II, No. 4.) 
I found it necessary to remove the anthers early in the 
morning as soon as it was light (and even before daybreak in the 
case of the ‘‘ Americans”) as they mature and shed their pollen 
very early. Sir George Watt quotes* Major Trevor Clarke's 
advice to apply the pollen overnight, ‘7.¢., Just before the flower 
has expanded or has been attacked by pollen-bearing insects.” 
This advice would apply more to the American varieties than to 
those I was dealing with. I tried removing the anthers over- 
night, covering the styles, and pollinating them the next day, but 
gave this plan up, as it was difficult to know which flowers would 
open the next morning, and none of my crosses so made were 
successful. I am inclined, however, to think that evening is the 
best time for removing the anthers, as in the morning they are so 
nearly ripe, that they are liable to burst and shed the pollen 
while being removed, and [had to give up a large number of 
flowers on that account. All who have worked at cross- pollination 
of flowers, are, I believe, convinced of the extreme sensitiveness 
of the stigma,—Charles Darwin often insisted on this-—and_ it
