Many of the fruits that would, if perfect, sell with the packing apples are 

 rejected on account of their reduced size or a few small scab spots. The 

 past year, although our crop was unusually fair, an average of a bushel of 

 apples per tree was thrown into the second class from this cause alone, 

 and from the combined effect of the above causes we lost on some trees a 

 barrel of apples. When an orchard is neglected, the injury from scab is 

 often very great, in some cases the entire crop being of value only for cider. 

 The college apples were pronounced by several buyers, and by the travel- 

 ing inspector for the packer to whom the fruit was sold, as the best they 

 had seen in the state, and yet the number free from scab was no greater 

 than on the trees used as checks, i. e., 12^ per cent. One of the trees 

 sprayed with modified eau celeste produced 12 bushels of apples and of 

 these 88 per cent, were free from all appearance of scab. The other tree 

 was very heavily loaded w- itli a crop of 22 bushels and this gave 59 per cent, 

 free from scab. On the affected fruits the spots were quite small and did 

 not give the apples an irregular and distorted appearance. 



The fruits from which the photographs for the plates were taken were 

 selected as showing the average appearance of the fruits on the 

 first of September. 



The following table shows the per cent, of the fruits that were free, 

 slightly scabby, and l)adly scabby:
