to the same family, are not very destructive to healthy 

 vegetable products, but prefer injured or decaying vegeta- 

 ble matter. They are to be found in injured cotton bolls, 

 in heaps of decaying cotton seed, in decaying fruit of all 

 kinds, and sucking the juices from injured fruil and trunks 

 or limbs of trees. I have found them in the ear of corn 

 only when such ears had been previously injured by other 

 cause. It has been stated, however, that they will attack 

 healthy kernels even in the bin ; but I am inclined to think 

 this would not occur if they had not been introduced there 

 in the larvfe stage in diseased corn, and after eating that, 

 were forced to eat the health}* kernels. 



Remedies. 



The best remedy in every respect for killing grain insects 

 is hisulphide of carbon. It is cheap, effectual, and easy to 

 apply. Bisulphide of carbon, or the new fuma bisulphide 

 of carbon, can be obtained of the manufacturer, Mr. E. R. 

 Taylor, Cleveland, Ohio, in fifty pound cans for ten cents 

 per pound, or in smaller quantities at a little more per 

 pound. 



One pound of the bisulphide of carbon is ample for one 

 hundred bushels of grain, provided it be in a comparatively 

 tight bin or granary, and the grain is not in the husk or pod. 

 If the bin or granary is quite open and contains many holes, 

 it will be necessary to use more bisulphide of carbon, since 

 it will evaporate and escape. The holes should be closed as 

 much as possible. The grain should not be stored in the 

 pod or husk, since it is almost impossible for the fumes of 

 the bisulphide to penetrate through the husk of an ear of 

 corn, and much less through the pod of a beau or pea. 



In view of the fact that many grain insects attack the 

 grain while it is in the field, and are thus carried dire^ctly 

 into the granary, it is advisable to make one application of 

 the bisulphide of carbon immediately or very soon after the 

 grain is gathered and stored. The grain should then be ex-
