especially wished to know about San-U-Zay. Knowing that I had 

 tested many of the oils, they asked my opinion. 



I wrote something- as follows : "Last year we tested San-U-Zay; 

 and it was absolutely worthless. Last fall we sprayed with San-U- 

 Zay, and also in the spring-. The fall treatment killed the scale and 

 did no injury to the trees; the spring- treatment killed the scale, but. 

 did injury to the trees." I wrote them that the evidence had led u? 

 to believe that the San-U-Zay could be used on apples, as in our 

 test the fall treatment did not do any injury. 



Member. That is not a miscible oil, is it? 



Prof. Symons. The San-U-Zay is not exactly a miscible oil. 

 because 3-ou have to use Sal Soda in mixing it. In the first year they 

 did not tell us to use Sal Soda, and we went ahead with the regular 

 directions, and did not get results. I wrote to Mr. F. G. Street the 

 other day, and asked him for another sample of oil. He said he had 

 decided to discontinue sending out five-gallon samples to experi- 

 ment stations ; that he did not consider it a fair test ; and having such 

 a great business, did not desire to do any more work in that line. 

 I simply acknowledged the letter and g"ave him my views in the 

 matter. 



Member. I had a little experience with that company. I read 

 their circulars, and thinks I, it's all right, sent for a barrel. When 

 the barrel came, I saw the directions to put some Sal Soda in. I 

 had expected a material ready to put on the trees. I was disap- 

 pointed, and asked that they take the barrel back. They did not 

 want to do it ; but I told them I did not want to bother mixing oils, 

 and would pay the freight both ways. They then took the barrel ofif 

 my hands. 



Prof Symons. The sooner the farmer appreciates the fact that 

 he should not believe everyone that comes along with a silver tongue, 

 the better it will be for him. It is absolutely useless for men to try 

 on an extended plan a solution that they know nothing about. That 

 is the value of the experiment station. The five-gallon experiment 

 is a small one ; but everything is on an equal basis, and is made as 

 nearly perfect as can be under the circumstances. It does give me 

 a better opportunity to answer a man's question with partial intel- 

 ligence at least. If a man writes in to me and says, "What do you 

 know of San-U-Zay?" and I write back to him, "Do not know any- 

 thing about it," he gets my letter and says, "I'll try it." If I can tell 

 him that I have tried it, and had good or bad results, I do give him 

 a fact to go by. That's the reason I test these solutions. It is very 

 tedious at times. We have learned, however, that what the farmers 

 want to know is — What is effective along with ease of application? 



Geo. Fohl. If you boil Lime Sulphur, what proportions do 

 you use? 



Prof. Symons. Twenty pounds lime ; 15 pounds sulphur. 

 Geo. Fohl. How long do you boil it? 



Prof. Symons. Three-quarters of an hour, or until it has pro- 

 duced an amber colored solution. 



H. M. Anderson. Does not the color of the solution depend 

 on the lime you use? 



Prof. Symons. No ; usually on time of boiling. 



H. M. Anderson. Are you sure?
