352 ANNUAL REPORT OF THE Off. Doc. 



advanced stage, you will want it much more drastic than you will 

 for a peach tree that is just starting. If you make it yourself, you 

 can make the ratio high or light, just as you wish. You can make it 

 14 to 1, or 20 to 1, just as you like. So I think they w^ill be better 

 than the preparations on the market. 



MR. HUTCHISON: There was a suggestion made that we create a 

 Department of Horticulture. I presume this will be a part of the 

 Board of Agriculture, and I think this should be doner because the 

 Department of Horticulture is an important one, and I think the 

 Board should take some action toward creating this Department. 



MR. CLARK: I don't want to offer any results, but I want to tell 

 you what we did on our farm in Soutl-.ern Indiana the past few years. 

 We tried to see first what we could do with lime, sulphur and salt, 

 but it is so troublesome to prepare that we finally decided to see 

 what could be done with kerosene. We did so, and I want to tell you 

 the result. The Scale, I suppose, is as nearly destroyed in our 

 orchards there, as in any other orchards, where they have used other 

 preparations. We lost a few trees by too much oil, but very few 

 in comparison to the whole number. But I noticed this: the loose 

 bark on the trees nearly all fell off, and the trees are quite smooth. 

 There is no place for the little insects to harbor. We are so well 

 satisfied that we shall continue to use it. 



MR. HUTCHISON: Did you dilute it? 



MR. CLARK: No, not on the larger trees, but on the smaller trees 

 we used about 1 to 20, and the smaller trees were the ones we lost. 



The CHAIRMAN: Will the gentleman please tell us on what kind 

 of trees he used it? 



MR. CLARK: Peach, apple and pear. We are too far south to 

 raise a good apple, but our apples were as fair as any on the market; 

 the peach crop was a failure this jenr in our neighborhood. But this 

 is the home of the Kiefter pear, and we shipped the largest Kieffer 

 pears on the Louisville market. Two other parties shipped probably 

 as good; none better. Now, I tell you this just to show you what can 

 be done. The good pears that were taken to the market commanded 

 a. good price. I tell 3^ou that we shall continue its use. Unless 

 farmers do something, they will have to go out of the business, 

 and it is the hardest thing in the world to get a farmer to use lime, 

 sulphur and salt. There are only tv/o things to keep in mind in the 

 use of kerosene: to be careful and to use a small quantity. We can 

 easily use it. 



MR. SNAVELY: I want to put this question to Dr. Funk: whether 

 the use of these crude oils is not going to prove eventually destruc- 

 tive to the tree? 



DR. FUNK: It certainly will; we know that all oils will injure the 

 tissue of all vegetable matter. We know that pure kerosene will 

 destroy the scale, and if a man will select for his work an ideal day, 

 and force the pressure through an exceedingly fine orifice, making an 

 exceedingly fine mist, it may be all right, but the danger is that he
