later sprayings were omitted, while still other plots were given the 

 later spra3angs only. It was found in all this work that the injury 

 to the apples was confined to the early sprayings. In some of the 

 orchards arsenite of lime was used, in others arsenite of soda in con- 

 nection with the Bordeaux mixture, and it was thought by some that 

 he injury was due largely to the arsenite. However, in othe~r orchards 

 where Pa'ris green was used, and in one orchard where Bordeaux mix- 

 tur was used alone, there was the same damage by the rusting of 

 the surface of the fruit. We noticed, however, that on all trees that 

 were not afifectedby the drouth this year the amount of fruit afit'efcted 

 was practically nominal, not enough to effect the marketable product ; 

 but on trees injured by the drouth the amount of fruit damaged was 

 greater. It seems that where the trees were not affected by the drouth 

 that the apples outgrew the injury done earlier in the season. 



It ma}' not be out of place to mention the value of cultivation in 

 orchards. The apple men who packed the fruit in South ^Missouri this 

 year practically all say that in orchards that were thoroughly culti- 

 vated during the season it was possible to barrel up as many apples 

 as the buyers and owners expected that they would ; while in the un- 

 cultivated orchards in most cases there were about one-half as many 

 barrels per acre as estimated earlier in the season. This shows the 

 benefit of thorough cultivation during a dry season. I would em- 

 phasize this point in connection with this, that in uncultivated orchards 

 the mixture injured the fruit, and on account of the drouth the apples 

 were unable to recover, while on others given the same number of 

 sprayings the fruit was practicall}^ all marketable, being more thrifty 

 on account of the cultivation given. , 



In the orchards where the experiments were conducted this year 

 some of the owners were apprehensive of the result, and feared that a 

 part of the crop was damaged. In all cases there were as many bar- 

 rels of marketable apples taken from the sprayed plots as from the 

 unsprayed, and usually there was a somewhat larger per cent, from 

 the sprayed. However, the yield was not increased by the spraying 

 the present season as it usuall}- is, for often the yield may be increased 

 fully one-third by spraying. 



There is another point connected with the spraying work con- 

 ducted by the station that may be of interest. In our experiments at 

 ^fountain Grove we found that the trees sprayed last year set much 

 more fruit tlie present season that the check plots adjoining. This 

 is an important point and I hope that there are others present who 

 will give us some testimony along this line. 



From the results obtained this season I believe that it would be
