PROCEEDINGS OF THE SUMMER MEETING. 119 



Will the Bordeaux mixture speck or discolor the fruit? I wish to spray 

 my apples pretty soon. 



Mr. Smith : My own experience in this matter is all I can speak of. I 

 use six j)Ounds of sulphate of copper and four pounds of lime. I use Lon- 

 don purple in place of Paris green because it is not quite so heavy. I use 

 this amount to fifty gallons of water. 



Q. How much London purple do you use? A. Four ounces makes it 

 sufficiently strong, in my opinion. My greatest difficulty has been in 

 getting the lime in the right shape to add to the spraying materials 

 without clogging the pump. It requires a strainer before you add the 

 lime. I use milk of lime, but notwithstanding that it has a tendency 

 to clog the sprayer frequently. If we had the right kind of apparatus, 

 with a fine sieve, to run the milk of lime through, before it enters the 

 barrel, perhaps that could be avoided. 



Mr. Judson: I find that spraying two or three times doesn't do for 

 me. On my apple trees, last year, toward the first of August, you could 

 hardly find a wormy apjjle, and when I picked them there was hardly one 

 but was wormy. Where did th(3 worms come from? Did they come from 

 the few that were left, that did not get the spray, or from the neighbors' 

 orchards? I find it is necessary for me to spray two or three times 

 more. I have sprayed three times already, and I expect to have to spray 

 two or three times more, to get apples that are perfect. 



Mr. Morrill : You may have to spraj' your neighbors' orchards. 



Mr. Judson: That is what I wish to know. Will these fellows travel 

 very far ? 



Mr. Smith: Probably the gentleman will have to spray later in the 

 year. In 1894, I had as fine prospects for Baldwin apples as I ever saw, 

 and when they were one third grown they were entirely free from 

 worms, and I told everj^one I was going to have the finest kind of crop 

 of apples. Everything else came on, and I stopped spraying. The 

 apples were then as large as walnuts, but when I came to pick them every 

 one had two or three worms. The codlin moth kept working on them all 

 summer, and there was no rain. That question comes in, how late can 

 we spray advantageously to destroy these worms? I was never more 

 surprised in my life than that .year, and I almost lost faith in spraying. 

 The apples looked so fine and clear and large, and when it came to the 

 picking I didn't have any. 



A Member : That is the experience I had last year. I sprayed every- 

 thing, as I thought, as long as the bulletins recommended, and every- 

 thing that ripened before the very late pears was perfect. But after that, 

 even the Seckels, which only ripen ten days or two weeks later, were 

 wormy as well as the Baldwins and everything else. I might have 

 sprayed one or two times less, early in the season, and put it on later. It 

 jjerhaps would have been better. 



Mr. Morrill: I do not think Mr. Judson's questions have been answered 

 yet. He asked if the poison should be used with Bordeaux mixture. 



Prof Taft: I was asked that question last night, and my reply was 

 that when I get home next week I shall spray the apple orchard again, 

 and in that be guided by the conditions. If between now and then we 

 have warm and pleasant weather, I shall not think it necessary to use 

 the Bordeaux mixture, but I shall use the insecticide for the codlin moth.
