on pear trees, and within three days, with the Bartlett pears, I saw evidences of the 

 leaves being burned. 1 said to myself: If these leaves were injured, which were never 

 injured before, by the use of Paris green, there is a certain plum orchard that will 

 be injured in the same proportion, because the foliage will not stand what the pear 

 tree will. It is a sensitive foliage. The result was, that the orchard suffered a good 

 deal. I made up my mind that hereafter London purple would find some other fellow 

 to use it, and any of you who want the experience can try it, but no more London 

 purple for me. 



Mr. WooLVERTON. — I have had a little experience, too, with Paris green and 

 London purple. I use ten or fifteen pounds every year in my orchard, and I might 

 have something to say in addition I have had some unfavourable results by using 

 Paris green. I am very careful, as a rule, not to use too much of it. 1 only use 

 about three ounces to forty gallons of water, and surely that is on the safe side. But 

 I find the difficulty is this : that a man in adding the Paris green to each successive 

 barrel or puncheon of water does not consider the amount of sediment remainiog 

 from the preceding bari'el that is already in, and the result is that after a day or two 

 his solution is getting constantly stronger and stronger, and the result has been that 

 one season a large quantity of fruit was lost. So I think it is necessarj^ to speak a 

 word of warning in regard to this matter, that in adding the successive quantities to 

 the barrel it is well to remember that it is a substance that is rather heavy and 

 inclined to settle to the bottom, and it may become much stronger than we imagine. 

 I can also corroborate what has been said regarding London purple, and that with 

 somewhat of the same proportions I have had serious results to the foliage of apple 

 trees. The kerosene emulsion, that has been spoken of by Mr. Fletcher, I have used 

 a good deal with the Bartletts with excellent success, applying about the first of 

 June. 



Mr. FiSK. — I am interested in this. I have had some experience myself. 

 Unlike Mr. Willard, 1 have not burned my fingers with London purple. The last 

 two seasons I have sprayed with London purple, using one pound to one hundred 

 gallons of water, and so far I don't see any bad results to the foliage. I have seen 

 great evil 7-esult from the destructive work of the insect. I was spraying for a bug 

 that attacked my orchard three years ago, I think it was in 18'78. It was a small 

 insect, about a quarter of an inch long, with a long head, which, I think, Mr. Fletcher 

 told me turned to a moth. However, this insect attacked my orchard and my 

 neighbour's orchard three years ago. The foliage was badly eaten, and I resorted 

 during the next season to the use of London purple. I put it on very early, spraying 

 three times that spring. I succeeded in saving my orchard from defoliation, while 

 my neighbour's o-chard was totally defoliated. Last year I sprayed again, and had a 

 fail- crop of fruit, and my neighbour's orchard was defoliated for the third time. There 

 was one remarkable feature which struck me in regard to this insect, and that is 

 that it did not attack the Eed Astrachans. I had in my orchard one row of Eed 

 Astrachans and the foliage was not attacked by these insects, and my neighbour's Eed 

 Astrachan trees were never injured. I would like to know if any other gentleman 

 has had the same experience. I would like to know why this insect discards the Eed 

 Astrachan. 



Mr. Brodie. — I have used both Paris green and London purple. I used the latter 

 on hills of potatoes and got them burned. For a number of years I have used 

 Paris green on a thirty-acre orchard, and I have used an ounce to eight gallons of 

 water, and have used a force pump attached to an empty coal oil barrel on a spring 

 waggon. I have not the cyclone nozzle to my spraying apparatus, but I have one 

 which does very good work. "We have to be careful that the leaves don't fall into 

 the barrel. I have used the apparatus for the codling moth and the caterpillar. 

 While my neighbours are going through their orchards killing caterpillars with their 

 hands I only apply Paris green. We have to go through a second time, sometimes. 



Mr. FrsK. — If you had a strainer at the end of your tap at the bottom of the 

 barrel the leaves would not interfere with the flow. 



Mr. Fletcher. — Do you stand your barrels upright ? 



Mr. FiSK.— Yes.
