Summer Meeting. 101 



that they are numerous. I wouldn't advise him to spray for insects as 

 a means of prevention. I do not think it would pay to take the time 

 and trouble and expense to guard against getting these insects. But 

 when you have these insects, it certainly pays to spray. 



Question : Is spraying profitable when those all around you fail to 



spray ? 



Stedman. — Well, that depends entirely upon the insect.. 



Mr. J. J. Kiser. — Ladies and Gentlemen: I am very glad to have 

 the opportunity of speaking to you about my machine. But before I 

 begin, let me say that this machine is only a secondary matter with me. 

 I have been laboring for years to keep from spraying. If I can succeed 

 in doing away with that work, I ought to be at least a welcome visitor 

 to you. As a machine man, I want it understood that I am here for 

 saving labor and doing the work better, if possible. I want to say to the 

 professor that has worked so hard and faithfully that I may be of help to 

 the fruit grower and the fruit buyer. Now I don't write professor before 

 my name. What I know I have got by experience. I want to help 

 the farmers and ask for their attention to my machine. I began experi- 

 menting with a common baking-powder can. I found that it was all 

 right, but when the first dusting process came out it was too much work. 

 The matter came up for convenience and effectiveness. Last summer — 

 last May — the last week in May, I dusted my orchard with several diff- 

 erent things ; but all the things contained arsenic. I did not spray be- 

 cause I did not think it was necessary; because I did not have anything 

 to spray for. But last fall we were attacked with the Canker Worm. I 

 expect several lOO trees were effected, but I believe the dusting saved 

 them. I did not see a limb as large as my little finger that had been hurt. 

 Now, that is a fact. Another thing is a fact. This dusting had been going 

 on for several years. Now, if I may be permitted, I would like to say 

 a few words about formulas. First, it is a very important matter to get 

 this dust just the proper condition to apply. First, I get a barrel and 

 nail a couple of cletes along the sides ; then I set a kind of a sieve 

 down in it ; then I measure out ten pounds of slacked iime ; it wants to be 

 the quick Hme. I find that it takes about 3 quarts of water to make it 

 into the proper dust. I pour the water in and turn it over several times 

 and work it up "and soon it is all right. I do not let it get all piled up on 

 the sieve. The reason I said ten pounds of lime is that I can figure 

 easier vt^hat I am to put in. I would get me half of Bordeaux mixture 

 for the 3 quarts. Now I put this on and when it comes out it is like this 

 sample I have. You may look at it. This has not been ground. Now, 

 as far as the arsenic is concerned, I have taken Mr. Goodman's formula 

 for that. In the ten pounds of lime, one quart of water, in which 4 ounces
