pound to 50 gallons of water. If it is so mild that it requires three 

 pounds to do the work of one-quarter pound of paris green, it is certainly 

 unreliable. We would not often get enough into the worm's stomach to 

 cause him any inconvenience. Lime, especially dry lime, is very little sol- 

 uble in water. When our paris green is mixed up with lime and depos- 

 ited in the calyx of the apple and the calyx closes over it, there is not 

 much chance for it to get out. It will not dissolve and wash out. The 

 rain can not readily strike it in such a way as to knock it out. So when 

 you find your sprayed apples badly infested with codling moth, know ye 

 for a cex'tainty that the spraying was not properly done. 



■ Mr. Snodgrass: Did you ever use arsenate of soda? 



Mr. Burton: I never have. I can't get it mixed up; it is too coarse. 

 I don't get good results from it, so I never use it. 



A Member: Do you know anything about the dust prcxcss of 

 spraying? 



Mr. Burton: I am not disposed to try it. As I said before, in spray- 

 ing I always use a brass pump, as they will not corrode. A gentleman 

 bas .lust said that his brass pump has corroded, but I think he is mis- 

 taken, for if you would leave a brass pump for a year it would not 

 corrode, but it might get clogged up. The contents of the vessel will be 

 just as strong when you begm as when you quit, if it is mixed right. The 

 pump will keep the contents stirred up. Whenever we make a stop of a 

 few minutes we detach the pluuger and stir iip the contents before 

 starting to work again. 



Mr. Young: I have used the dust spraying for about two years, and 

 I prefer it to water. We, too, thought that it would be a little dusty, but 

 I find it cleaner than the liquid. Of course we always take the windward 

 side, and we get along very successfully. Of bourse I have not used it 

 long enough to tell whether it will answer every purpose or not. but it 

 has been very satisfactory. 



Mr. De Vilbiss: I want to say that I can burst my hose with 150 

 pounds pressure. I can't break the handle of my pump, as Brother Bur- 

 ton says he does, but I ran burst the hose. I believe he has an inf<^rior 

 handle. 



Mr. Burton: I must say that Brother De Vilbiss has an inferior hose. 

 I used to buy that kind, too, but the hose I have now will stand three hun- 

 dred pounds pressure before bursting. It is a four-ply hose, and is very 

 strong; in fact. I don't believe three hundred pounds pressure would 

 break it. The handle on the pump will break l)efore the hose will burst.
