This manual contains a presentation of the known 

 facts and data with respect to the common diseases of 

 fruits. It has been prepared primarily for the modern 

 agriculturist, the farmer, the thinking fruit grower, but 

 it should also be of service to any one who has an interest 

 in plant diseases. The fruits are taken up in alphabeti- 

 cal order. The discussion of the diseases proceeds in 

 order of their importance and prominence in the United 

 States. Particular attention is paid to the description 

 and illustration of the symptoms, to the cause and to the 

 generally accepted measures of control. Technical de- 

 tails are omitted as far as possible, though the effort has 

 been made to present the matter in as popular a fashion 

 as possible.
