SiR:^_In response to your request of recent date, I beg 

 iierewitti to make my annual report as Botanist of the 

 Agricultural Experiment Station for the year ending. 



The importance of studying the plant diseases caused by 

 plant parasites- has become increasingly evident. Special 

 attention has been given to the Grape Rot (Guinardia lid- 

 welii) and to the Fire Blight of Pome fruits {Bacillus 

 amylororiis) , and two circulars on these diseases have been 

 prepared and ar'e about to be sent to press, and the 'best

 are the cause of gi'eat losses, and this is especially true of 

 the Grape Rot, which is known to destroy the entire crop. 



Tlie Orange Rust of Apples las been studied with ref- 

 erence to the history of the alternate form, Gi/mnospornng-

 The biennial character of the cedar apple has been estab- 

 lished, confirming, independently, the work of Heald in 

 Nebraska. 



The problem of hieeting the pecan situation is becoming 

 increasingly important. This tree has been assumed by 

 many to be free from the attacks of fungous parasites, and 

 this view has been used as an argument to plant the tree. 

 It now develops that some varieties at least, if not all, are 

 attacked by the same organism which produces the scab of 

 apples, Fiisicladiiim cffiisum. Whether the treatment given 

 to apples may prove effective remains to be determined. 

 The extent of loss has been so great in some quarters that 

 it is of the highest importance that a careful study should 

 be made of methods of control. 



The two projects under the Adams Fund have been be- 

 gun. Several attempts have been made to carry out certain
