found successful is to dig trenches about one foot deep and sweep thi' lurvae 

 into them. They can walk and also hop about six inches. When a 

 sufficient number are in the trench the earth is filled in. I have spoken 

 to many villagers about it, but being fatalists they appear very callous. 

 I hope to get the collectors to take up the matter, as I cannot do much by 

 myself. The locusts did considerable damage to peas and mustard crops, 

 but not much to grain, which is now being cut. Sugar-cane and indigo are 

 being sown, and the young larvae will cause much damage to these crops 

 unless they are got rid of. There are such enormous numbers of them 

 that anything but united action on the part of the villagers is useless, since 

 a man may clear his own field, but unless the neighbouring fields are also 

 cleared it will be as bad as ever in twelve hours."
