"I have reason to believe that a number of millers have used 

 this remedy with very indifferent results, owing, in my opinion, to 

 the manner in which it was applied. In the first place, the mill 

 should be thoroughly swept (as every mill should be daily), and 

 if there are any broken panes of glass in the windows they should' 

 be replaced, the object being to make the mill as tight as pos- 

 sible. Then have a number of shallow tin pans, say, about fifty 

 to every 100 pounds of the compound used. Begin at the top 

 [bottom] of the mill, and place the pans where the insects are 

 the thickest. It is best for two to go together, one placing the 

 pans, the other filling them, using a watering-can or something 

 of the kind having a spout. 



"I apply it to the bolting reels and flour garners as follows: 

 I get ready, beforehand, a number of medium- sized bunches of 

 cotton- waste, two for each reel, with a string attached to each, i 

 dip these bunches into the bucket of compound, pressing out 

 with a paddle so they will not drip too much; then throw them 

 under the reel and down on the conveyor, leaving the string on 

 the outside so they can be recovered, then close the doors o^ the 

 bolting chesb tightly. I suspend one or two bunches in like man- 

 ner in the flour garners and screening bins. In applying it to the 

 wheat bins we level off the grain and place the pans on it filled 

 with the liquid. By applying it in this way to wheat bins and tak- 

 ing proper care to have the bins emptied and swept out oc- 

 casionally, no one need be troubled with weevils in their grain 

 elevators. There is one thing that we have discovered, and that is 

 that the compound must be reasonably fresh when used. If kept 

 for any great length of time it loses its strength, consequently it 

 should be used as soon as practicable after receiving it, and no 

 more should be ordered than it is intended to use. 



"Before commencing the use of bisulphide of carbon this mill 

 was badly infested with weevils and other insects. Now we are 

 nearly free from the pests. I do not say that this remedy will kill 

 every insect in a mill. I do not think there is an insecticide made 

 powerful enough to reach every nook and crevice, such as we 

 have in mills; but we do know that by a judicious use of bisul- 

 phide of carbon in warm weather, when the insects are in full 

 force, and by a due regard to cleanliness all over the mill, any mill 

 can be rid of the pests. 



"The compound being highly inflammable, there should be no 

 fire or lights used in the mill at the time it is applied. The best 

 time to apply it is Saturday evening, and the mill should be kept 

 closed till Monday morning." 



There have been so many exaggerated reports about the nature 

 of this chemical compound that it is necessary to give a few notes 

 regarding it in this place. In this connection I can do no greater 

 service than to quote a letter from Mr. Edward K. Taylor, of Cleve- 

 land, Ohio, the leading manufacturer of bisulphide of carbon in 

 this country. It appeared in the ''American Miller" for Septem- 

 ber, 1895, and reads as follows:
