annuals with the wood/ perennial tree-cotton. It is desired 
to raise progeny of hybrid-vigour, i.e., in particular a 
general improvement of plant constitution in resistance to 
plant pests and disease, increase in fields and possibly to 
secure fairly good cotton in spl t e of frequent wet weather. 
An experiment in mass selection for purple maize has now 
reached the fifth generation. At the second and third gene- 
rations the plants were self— pollinated to ensure a certain degree 
of Inbreeding; after that natural cross-pollination among the 
plants in each bed were perwlttsd, and a mixture of purple 
seeds from different plants selected. In this way a i&.irly 
oure purple strain has b^en established, which retains the 
vigour liable to he lost in the isolation of pure lines. 
Two further experiments on Pachyrrhizus ^Yam Bean) are 
beir^ started to determines- 
(a) whether a reasonably good yield of tubers are 
obtainable if harvesting be practised immediately 
the flowers appear; 
(b) the possibility of ha-vroting profitably young 
pods for consumption and subsequently gather a 
harvest without* appreciable loss of weight in 
tuber yield. 
These two experiments complete a aeries of 8 and will give 
expression to many facta hitherto unpublished in vegetable 
gardening books. 
42 various vegetable packets have been introduced by 
Dr. Koriba from Kyoto Takii Nursery Company. Japan. These sets 
are for trial in the vegetable plots with a view to selecting 
new vegetables s*hich will thrive xn local conditions. 
sello'wiana plants by bud-graf t operation. For this purpose 
Lautana camara strike have been planted. It should be noted 
that Lantana sellowlana is free-flowering and prostrate; the 
operation will effect, a pendulous purple flowering standard 
plant. \ \ < \ \ 
Similarly it ieXdesired to raiee\ standard Petrea volubilis 
on Peti'em rugosa stock. \ \ 
new planting, destroyed plants* corrections* and a general 
survey in bringing them up-to-date.
