sticky. A bag, 8 ft. wide and 3 ft. high, is a convenient size, the sides kept open by bamboos 3 ft. long, 

 which serve as handles for grasping it. The width is about as much as two men can run with. A smaller 

 bag may be suspended by ropes (see fig.). Mr. Lefroy strongly recommends such an appliance, and 

 doubts whether any better will be found. The work is best done by co-operation and the treatment of 

 large areas together, as bags cost something to make. (6) It has been found that a mixture of bran and 

 jaggery serves as a bait for the bugs, and that they could be captured and destroyed easily when they 

 can be got to congregate together by this means. 



An important point to be remembered is that the best work can be done by attacking the rice-bug 

 when in the field and before the rice comes into ear, and not by waiting till it has invaded the fields. 

 The cultivator should therefore look out for the insect and its eggs and destroy them. For, if let alone, 

 each pair will in a month or so produce about 24 bugs and in two months 288, and so on. The enemies 

 of the bug should also be recognized, and must never be destroyed. 



[To make kerosine emulsion : Boil \ lb. sliced bar soap in 1 gallon water till dissolved. Take off 

 fire and add 2 gallons kerosine, agitating mixture till a milky emulsion is formed. Dilute to required 

 strength (usually with 6 to 10 parts water) for use. Where crude oil is used, dilute each gallon with 

 66 gallons water, or | a pint to one kerosine tin water.]
