grains from insects. Besides, if it be possible to erect a plant at a high 

 cost, the sure treatment with carbon bisulphide is certainly preferable, 

 there being skilled supervision to guard against accidents. In the case 

 of the Indian cultivators and householders who deal with small lots, 

 for separating insects and dirt from the grain the country sieves and 

 hand-winnows are effective and cheap appHances. 



It will be apparent that there was room for experiment aimed at 

 finding means of prevention of damage. Such experiments were under- 

 taken more from the view-point of the Indian householders, and culti- 

 vators than of dealers in bulk. As a result, a method has been worked 

 out which is inexpensive and can be easily adopted by the former and 

 adapted to the receptacles they use for storage. The method is also 

 appHcable to storage in bulk.
