ci" arsenic has been dissolved, poured in will be right. Stir it well. It 

 does not dissolve; it gets mixed. I double the strength of the arsenic. 

 I put I pound of arsenic to 20 pounds of water. 



Now I have dusted grape vines, strawberries, raspberries, black- 

 berries, currants, gooseberries, plums, apples, quince and nearly all kinds 

 of fruits. I cannot see that I hurt the foliage of anything w'hatever. 



One thing more. About the kerosene emulsion for the sucking 

 insects I use 1-2 pound of concentrated lye to 3 quarts of water and that 

 makes a preparation so caustic that when it touches an insect of this 

 kind, it fairly sets it a fire. Sometimes I mix sulphur with it. It is 

 a splendid thing for this kind of work. I guess you could put snuff in 

 it, too. Road dust and ashes can be put in. Now, I am just waiting 

 for results. But it has been practiced for quite a number of years and 

 the results so far as I know have been good. As a matter of fact, I 

 think it can be fixed a great deal easier than the liquid spray. My boys 

 think nothing of going out and dusting our apple trees. It is not hard 

 work; just as fast as you drive along you can dust. You can dust three 

 of four rows of trees at once. In fact, I feel a little bit like one of my 

 boys when he told me that he would not spray all the orchards on the 

 farm for them, Now^ this machine is not like working a pump handle. 

 All you have to do is to turn the crank. It is certainly easy and effec- 

 tive, and so far as I know% is as effective as a Hquid spray. We are all 

 interested in getting this work dow^n to save all the labor that we can, 

 and I believe we can do this if we will work hand in hand and heart to 

 heart and accomplish the very best results. I am in for the very best 

 that there is and as far as my machine and my interests in it are concerned, 

 you may run over that if you like, but give me the very best methods 

 you have for the insects and fungus. 



Discussion. 



Prof. Stedman, do you thing the dust spray as effective for in- 

 sects as the liquid spray? 



Prof. Stedman. — In some cases it is and some it is not. I always 

 advise people to get both machines. The dust is easier and quicker, and 

 many will dust when you couldn't get them to spray. But in some in- 

 stances it is not as good as the liquid spray. For the Codling Moth, it 

 is not as eft'ective. Now, on small plants, it is better. The lime without 

 anything else is good. 



Prof. Von Schrenk.— As I have not tested the dusting machine, 

 I dare not express myself on it. I would like for it to be tried on some 

 trees for us. The answer that I would have to make now is somewhat 

 like Prof. Stedman's. It is good in some cases and others it is not. If
