As will be seen, the results are indifferent or negative. The con- 

 ditions were such, however, that little reliance can be placed on this 

 test. 



In no case was the foliage of the spraj'ed trees injured by the 

 weaker mixture. Some Baldwin trees spra3'ed freely with a mix- 

 ture of the strength of one pound of Paris green to 200 gallons 

 water. Were considerably scorched, however. In the use of Paris 

 green or London purple it has been found that a fine, evenly divided 

 spray is less liable to cause injury than is a coarse spray. 



As a rule, Paris green is to be preferred to London purple, as it 

 is less variable in character and is less liable to damage the foliage. 



In general, we conclude from the results of the past season's 

 work : Spraying with Paris green is effective in greatly reducing 

 the injury from attacks of codling moth. A mixture so dilute as 

 one pound of the poison to 320 gallons of water, may be effective. 

 A mixture of the proportion of one pound of poison to 250 gallons 

 of water was more effective, in some instances. 



The use of a mixture of the strength of one pound to 200 gallons 

 water endangers the foliage unless carefully applied. 



IS SPRAYED FRUIT UNWHOLESOME? 



The objection is frequently raised that fruit which has been 

 sprayed is unsafe for food ; that enough poison will adhere to render 

 the fruit dangerous. 



The matter has attracted some attention in England recently, and 

 there has been an outer}' against American apples. One of the 

 Boston papers last winter quoted a writer in the Horticultural Times 

 of London, assaying: "It is admitted that this insecticide (arsenic) 

 is used upon the fruit itself until it is completeh' saturated ; that it 

 is applied to the fruit several times before it reaches maturitj', and 

 if the weather continues dry, the arsenic clings to the fruit and what
