The grain to be treated should be in a tight bin. If the 

 grain is not stored in tight bins, such a bin or box should be 

 constructed, and the grain treated in it in successive portions. 

 If the grain is wheat or oats or shelled corn a long tube open 

 at both' ends but carrying within it a snugly fitting rod should be 

 thrust into the grain until one end of the tube is near the center 

 of the bin. The rod should now be withdrawn and a quantity 

 of the Bisulphide of Carbon should be poured into the tube, the 

 rod having been withdrawn. About one ounce of liquid to each 

 hundred pounds of grain in the bin should be used. Finally, the 

 tube should be withdrawn, the liquid being left in the center of 

 the grain mass. 



Another recommended method of applying the insect! 

 is that of soaking with it a ball of cotton fastened to the end 

 of a pole. The soaked cotton may now be pushed into 

 grain. Two or three applications of this kind in different places 

 in the bin will effectually destroy all insect life in the bin. If 

 the corn is in the ear, a convenient method of application is to 

 pour the Bisulphide of Carbon into small open dishes, setting 

 these dishes about on the corn. Or the surface of the stored 

 corn may be sprinkled with the liquid. The Bisulphide is 

 heavier than air, so that it sinks down into the bin. 



Great care must be taken that no lighted lamps, cigars or 

 burning material shall come near the Bisulphide of Carbon in- 

 near places where it has been used until the odor has pas 

 entirely away. The liquid is highly inflammable and explosive. 

 Xo danger, however, need exist if proper care be taken. Grain 

 treated with Bisulphide of Carbon is not injured at all by the 

 insecticide. The bad odor passes off in a few days. 



We shall be glad to receive notes con the presence 



and habits of the Wheat-straw Worm and the Grain Moth fi 

 any Kansas obseryers.
