40 THE JOLA OR DECCAN GRASSHOPPER 
mendations as to combative measures presented here apply 
especially to Mysore. While they may be considered to 
apply, in a general way, to the whole infested area, it is 
quite probable that they may be more difficult to carry 
out and also less remunerative elsewhere. If, for instance, 
large areas of waste and grass land occur in infested regions, 
it is clear that the difficulty of combating the pest would 
be greatly increased. In such a case, it would be neces- 
sary to carry out the operations on the waste as well as 
on the cultivated land and this would, of course, increase 
the cost very much. This does not apply to the infested 
areas in Mysore, for, up to the present, the grasshopper has 
been confined to areas where practically no waste land 
occurs. A second point which should be remembered is 
that in Mysore the infested areas have as chief cereal crop, 
jola, a cereal which, with a normal yield, is more profitable 
than most of the other dry land cereals, such as navane, 
sajje and savé. The crops in Mysore are, therefore, 
sufficiently remunerative to warrant an outlay very much 
ereater than that which is necessary to combat this pest. 
I have deemed it necessary to add the above explana- 
tion froin the fact that there is no commoner mistake 
than that of attempting to apply the results obtained in 
one place and under one set of conditions to other locali- 
ties and conditions which may be decidedly different in 
their nature. Remedial measures, to be of any certain 
value, must be worked out with a knowledge of local 
conditions and with a view to suit those conditions in the 
most intimate manner possible.
