78 PEACH LEAF CUKL: ITS NATURE AND TREATMENT. 



In taking the percentage estimates of disease shown in the following 

 table, the trees were examined in north and south rows. This was 

 done so as to work across the lines of the experiment rows rather than 

 with them, and for the purpose of avoiding any influence which a 

 knowledge of the sprays used on the trees estimated might be thought 

 to exert.
