paign to local practices and to organise measures against him; 
then to spread a knowledge of this and kindred things over a pro- 
vince. It is inevitable that one then gets drawn into education, 
and, for the vast influence it brings, into such productive things as 
silk, for they appeal far more to our people and bring us into touch 
with them very much more quickly than anything else. Above all, 
to answer every enquiry courteously, to miss no opportunity of 
showing the value of the work and to be able to give sensible 
advice whether it be on the subject of Ants eating the sugar or an 
outbreak of army-worm over 100,000 acres. 
In figures our work comes out to this; our list shows 104 import- 
ant pests, of which we know the life-history now of 74, of 75 we 
have prepared plates such as are shown, of 65 the plates are 
published and available for every-day use, for 40 we have simple 
easy methods of prevention or destruction, and against another 
21 are now working out in the field measures which will probably 
be effective with modification to suit local circumstances and 
which we expect to be able to apply over large areas of country. 
We have said nothing here as to our technical difficulties, but 
they are not of the less importance, and it has been a very big item 
in our work merely to get our species identified and to keep up 
the technical side of the subject. We owe a great debt to those 
workers in Europe and America who have examined our collec- 
tions, identified the species and enabled us to have a solid basis of 
accurate classification to work on. We have a quarrel with system- 
atic entomologists as such owing to their pedantic changes of 
nomenclature; but we freely admit our debt to them, and one of 
our activities is concerned solely with making collections and 
sending them to workers in Europe for the furtherance of purely 
systematic work. How important this is an example will show. 
Schenobius bipunctifer is a familiar species of Pyralid, a yellow 
Moth with a black spot on each forewing. If you are working on 
it as the Rice Stem Borer, you get it in abundance and can breed 
it, but you get also an Insect very closely resembling Chilo simplex, 
which is the Stem Borer of maize, sorghum and other cereals allied 
to rice. The ordinary worker concludes that rice is attacked by two 
species, Schenobius bipunctifer and Chilo simplex; but it has been 
proved that this Insect, closely resembling Chilo, is the male of 
Schenobius, its venation being quite distinct. Now the whole of our 
practical measures would be radically different if we thought that 
Chilo usually attacked rice as well as maize and sorghum; but we
