TWENTY-FIRST ANNUAL MEETING. 87 



oil and pvrox. For fertilizer we are using basic slag before 

 we plow, and carbonate of lime after we plow. We plow all 

 our orchards in the spring, and cultivate up until about the 

 middle of July. We do not sow any cover crop, but allow 

 the weeds to grow as a mulch, and plow them down in the 

 following spring. 



For pears we spray with crude oil, and after the blooms 

 drop we spray with pyrox, and about four weeks later again 

 with pyrox. We use basic slag and carbonate of lime on 

 pears, the same as we do on apples. 



On the grapes we spray early— that is, just as soon as 

 the buds start we begin to spray with pyrox. We put it on 

 about twice after that. We fertilize the same for the grapes 

 as we do for the pears. 



That is about all I have to say. I told your Society that 

 I did not want to come here and make an address, but if 

 there are any questions that any of you want to ask, I will 

 be glad to answer them. 



Discussion. 



President Rogers : The matter is open for discussion. 

 Mr. Repp is well known as a very practical man, and he has 

 some peculiar ideas. We should make the most of his infor- 

 mation while he is here. 



Professor Gulley : I would like to ask a question about 

 the use of that crude oil for the scale. Have you been using 

 that long? 



]\Ir. Repp : We have been using it for about twelve 

 years. 



Professor Gulley : Tell us just exactly how you use 

 it and what it costs. 



Mr. Repp: In using it as an insecticide, we use that 

 which tests 42^ gravity. 



It costs 9^ cents f.o.b. Philadelphia. We take the oil and 

 test it when it arrives, to see if it is of the proper gravity. 

 After we test the gravity, we put it into a tank, turn live 

 steam into it, and heat it up to about one hundred degrees, so
