me to use crude oil, and it was very easy to rid myself of 

 the scale, and I got ready and gave those trees a dose. I told 

 my boys to kill the scale and not spare the oil, and I stood bv 

 and saw them do it. They sprayed those trees until the oil 

 ran down in rivulets ; they drenched the trees in crude oil. I 

 supposed it would kill the tree ; I knew the scale would die, 

 any way, I had had one block of trees killed with it, and I 

 was scared. Well, there ware some of those buds just showing 

 white at the ends. Well, I didn't kill those buds ; I didn't kill 

 one out of a thousand. I had a fine crop of fruit on the or- 

 chard, and I did kill piles of scales, and I never saw trees 

 thrive and have a much more luxuriant foliage than those trees 

 did that year, with the nice crop of fruit they bore. The next 

 year T found they were still infested with scale; I hadn't killed 

 them all. So when the spring came, I thought I would use 

 some more oil, and I gave them a light dose of oil. I don't 

 think I used one-quarter, and perhaps not that, because I 

 only had a few scale compared to what there had been the 

 year before, so I gave them a very light dose of oil, and my 

 word for it, it killed almost every tree of that four hundred 

 in that block. Now then, why it was, I don't know. I have 

 been listening here to what the professor said, and I think it 

 was the accumulative effect ; the heavy dose did not kill the 

 trees when they were literally drenched, but the light dose 

 did kill them, and I think it was the accumulative eft'ect. and 

 I think that is one of the great dangers in using oils of any kind 

 for anything, and that is one of the main reasons why I am 

 so afraid of it. That was the effect in those trees, and it killed 

 trunks and all ; I couldn't spray them again. Then I went 

 to this Professor Jones, as I call him, and told what the result 

 was. Well, he said, you didn't use the right kind of oil. These 

 professors have got a way of slipping out of most everything, 

 and he said, it was your fault, you didn't use it intelligently. 

 Why didn't you get a hydrometer? and I said, I didn't know 

 there was such a thing in existence, what do you call it? He 

 said, you must test the oil, and you must have it 43 degrees. 

 And I got the oil, and I took his word, and it tested 44 degrees, 

 and I put that on with the same result. I killed my trees, prac- 

 tically killed them — as a good many people said, killed them
