Provinces, does not appear to affect cotton grown in the rain- 
forest belt or near the coast, where more humid atmospheric 
conditions obtain. A series of plantings of native cotton was 
therefore made at intervals of approximately three weeks, from 
the beginning of March until the end of J ah primarily to find 
out whether plants raised when the rainy season is well advanced, 
and during a period of comparatively high atmospheric humidity, 
would be susceptible to ‘leaf-curl.’ It was found that cotton 
planted as the rainy season advanced, up ‘to the end of July, was 
least affected by ‘ leaf-curl.’

vented, but the yields increased to a remarkable degree, com- 
parable with those obtained in any country where ground-nuts 
are produced. The difficulty of explaining why earlier planting 
eliminates ‘bunching’ is intensified by the fact that the ground- 
nut is a leguminous plant, and lives in symbiosis with its root- 
nodule organisms. Whether the ground-nut or its symbionts or 
both are adversely affected by too late planting remains to be 
proved.”’ aD. 
Potatoes grown from single eyes.—The shortage of seed 
potatoes in the spring of 1917 created a good deal of discussion 
in the Press as to the advisability of cutting tubers for planting 
into small sections instead of planting them whole. In order to 
test certain assertions as to the heavy yield from small scraps of 
tubers containing single eyes, the following experiment was con- 
eventually to be placed in a cold shed to check too rapid growth, 
the weather being too inclement for planting. 
The ground used was part of an old market garden that had 
been more or less derelict for several years. It was very heavy 
and dirty and it had to be dug when very wet. In that condi-
