APPENDIX 



Since there is a marked resemblance between the spot as 

 described in this and that attributed to Lime Sulphur injury as 

 described by the Illinois Experiment Station (Bulletin 185), I 

 wrote to Mr. E. W. Allen of Harristown, Illinois, from whose or- 

 chard the fruit came, to learn the history of the fruit as it de- 

 veloped, especially with regard to the spray used. Mr. Allen 

 writes the following: 



"I went over my trees and picked off all apples showing 

 the spots, which amounted to a barrel. There was very little 

 trouble after that. Two of the apples you have wers from an or- 

 chard one mile away where no spray had been used. 



"As to fungicides, I did dormant spraying 8 gallons Com- 

 mercial Lime Sulphur to 50 gallons of water, then just as petals 

 were about all off I used one gallon of Lime Sulphur to 50 of 

 water and two pounds of Arsenate of Lead paste to 50 gallons of 

 water. Then in ten days used the same spray again, and that was 

 all I did that season. 



"I had a fine apple crop but it looked for a while like 

 the trouble would ruin my crop. The first sign would be a little 

 red spot, then it would enlarge to the size of a 5 cent piece, 

 then get brown to a black."
