 Mr. Bourne has said, we have never

 that he only blames them for not giv-

USE OF PARIS GREEN. 



Sir : — I have great pleasure in second- 

 ing Mi\ Beadle's motion on page 279 

 of 188G, that all funny articles should 

 be put in the facetious column ; and 

 there ought also to be a column for all 

 doubtful or dangerous articles — such as 

 Paris green, for it seems to kill as 

 often as cure. See page 125 for F. W. 

 Ross's experience, also page 156 for J. 

 L. Thompson's, with a teas))Oonful of 

 Paris gi-een to a patent jxiil of water 

 and his killing the bugs and leaves at 

 the same time. On page 176, W. 

 Dixon fared better. On page 108, 

 Senator Plumb uses a dessert-spoonful 

 to a pail of water for his plum and 

 other trees. Surely his name cannot 

 have anything to do with his using 

 such a large quantity so successfully. 



In the summer of '84 I saw in the 

 IForticulturist a recommendation to put 

 a teaspoonful of Paris green in a patent 

 pailful of water to kill the curculio on 

 plum trees. Accordingly I put a tea- 

 spoonful of Paris green in a pail of 

 water and sprayed my plum trees and 

 killed the curculio and the leaves at 

 the same time, and was minus my 

 plums for that year. In 1885 I let 

 nature have a chance and had half a 

 crop of plums. Last year, after seeing 

 so many favorable reports of S})raying, 

 I thought I would try it again, and 

 this time with half a teaspoonful to a 

 pail of water for six plum ti-ees, with 

 the same result as in 1884, and I caine 

 very near saying a bad word against 

 Paris green and all who recommenil it, 

 but I restrained myself when I came 



to think that I had no patent on my pail 

 as recommended. But I see, on page 

 156, that Bro. Thom|)Son, with his 

 jjatent pail, fared equally as bad ; and, 

 on page 39 of 1887, Mr. Beall says the 

 foliage is injured b}' using too much 

 Paris gi-een. 



Now it is just [)ossible that there 

 are other conditions of danger in the 

 use of Paris green, such as drought or 

 sun heat. It was after the sun had 

 been shining strong all day that I 

 noticed small brown spots appearing 

 on the leaves, and in a day or two 

 more they begun to curl and drop off 

 and the fruit dry up. 



I am of the oi)inion that there is 

 much to learn as to the quantity, time 

 and mode of apjjlying insecticides (suc- 

 cessfully). Could not some of our ex- 

 perimental farms be induced to try 

 experiments with insecticides and report 

 the best mode for success ? 



Alex. Grey, Niagara Falls, Feb. 12. 



[Note. — While it is well known 

 that too much Pai'is green will destroy 

 the leaves of the trees and cause the 

 fruit to fall, we do not think half a 

 teaspoonful, or a whole teaspoonful to 

 three gallons of water could have any 

 such effect. Some other cause seems 

 to have contributed to the fall of the 

 leaf last season.]
