crawl back. Jarring the tree will prevent that. If applied 

 •early it will certainly destroy them all. 



Mr. Myrick of Springfield. What is the comparative 

 ■cost of paris green and pyrethrum? 



Prof. Maynard. I believe we figured the cost of the 

 paris green at about ten cents a tree. Pyrethrum costs 

 sixty cents a pound and paris green about twenty-five 

 cents. 



Mr. Hadwex. I would also like to inquire if it has 

 proved destructive to the codling moth? 



Prof. Maynard. No, sir ; we have not been able to af- 

 fect them at all. But perhaps we were not as thorough and 

 as careful in our experiments as we might have been. 



Mr. Upton of North Adams. One gentleman has made 

 a very practical inquiry : What shall we do with the rose 

 bugs ? I have had that question to meet from year to year 

 by the destruction of a certain portion of the blossoms upon 

 my vines by the rose bugs. I got rather desperate one 

 year. I did not know exactly what to do, but I said to 

 myself, "I will apply the same remedy to the rose bug 

 that I apply to the potato bug. I don't know what the 

 result will be and I don't care ; I only know this : it will 

 either prevent the rose bugs from eating up the blossoms or 

 it will kill my vines." So I applied paris green to my 

 grape vines the same as I would apply it to the potato vines 

 to destroy the potato bug. I gave them a thorough sprink- 

 ling with paris green, and the result was most satisfactory. 

 The vines were covered with the insects, but I destroyed 

 them entirely, did not injure my vines at all, and got a 

 large and abundant crop that year. I am satisfied that 

 paris green will do the work which nothing else will do. 



Mr. Briggs of Springfield. You will often find small 

 peaches covered with rose bugs. For the last six years I 

 have used this means to get rid of them : I take an old 

 rubber boot or shoe and put it on a bed of coals in an old 

 pan or kettle, and in the early morning carry it around 

 among my peach trees and grape vines, as close as I can 

 get to them. The smoke is so ofifensive to the insects, that 

 after two or three experiments you will not find a rose bug 

 on a peach tree or grape vine.
