the ge a principles oe whe h are generally — most of the 
cask ol measures that might be adopted against such i s and sugges- 
tions are heey as to ‘the prada that might be pecuknt by gardeners 
for ee control. 
At end a warning note is sounded regarding the necessity for 
prompt ‘e08 ecrcugk action in the matter of ai Aly nting the introduc- 
t 
tion into the country of ee foreign pests with consignments 
of nursery stock, fruits, tubers, , that are imported in large quantities 
nowadays. The author has dy a list of the more prominent foreigr 
pests in a paper he read at the Bombay Session of the Congress. 
Pollen sterility in relation to vegetative propagation.—By 
Pos 
Pollen iskent is a iii feature of plants that are vegetatively 
raised and the subject is of importance economically as it explains the 
shedding or abortion of fruits in a large number of instances. 
Flowers of about thirty different plants were examined to aoe 
the extent of sterility in them and the list includes some grasses and 
plants that propagate vegetatively in eka and a few ciation "tele 
besides other plants that are raised from cuttings. 
Sted or concludes that it is wrong on principle to Het decrees crops 
like Pepper, , Car damom, Vanilla, Moringa and others which are valued 
for their fruit or see solely by vegetative sete aint pa te ‘that sh 
able gs ge may be introduced in rrent methods in the ¢ 
of these and other mponozentcally Sis yor” pike so as to onan’ i
