production of the disease, and indicate that remedial measures 

 can be successfully applied. The other two diseases are the Leaf 

 Spot (Cercospora beticola) and Beet Scab (Oospora scabies) . 



Mr. Duggar's experiments with leaf-curl of the peach (Bul- 

 letin No. 164) show quite clearly that this very serious disease 

 which has been prevalent in New York State for the past two 

 years can be largely prevented by timely spraying. 



Mr. Duggar has also written two circulars as follows : 



No. 4 — " How the Plant obtains Its Food from the Soil." 

 No. 5—" How the Plant Obtains Its Food from the Air." 



Ths investigations in progress for the coming 3^ear are to be 

 continued along these same lines, especial attention being given 

 to studies of edible and poisonous mushrooms, the wood destroy- 

 ing fungi injurious to forest and shade trees, and to diseases of 

 fruit and farm crops. 



Doctor Duggar is now in Europe where he will remain for one 

 year, for the purpose of perfecting himself in certain lines of 

 research in plant physiology. This subject is a very important 

 one in connection with the investigations on plant diseases due 

 to fungi and certain plant diseases are due entirely to physiolo- 

 gical causes. During Dr. Duggar's absence Mr. W. A. Murrill 

 is carrying on the investigations which he had in charge.
