The writer triet^ the culture of our fungus on "Pernau" in the pots in the 

 green-house during the winter, beginning from Oct. 30, 1924 to April 12, 1925. 

 As the epidemic was itiduced artificially on the older plants, an abundant pro- 

 duction of the uredospores was secured. They were transferred by the same 

 method as in Experiment III from the older to the younger plants.
