days later showed that all of the 12 inoculated buds were ruined 

 by the fungus while the 13 checks were opening and showed no 

 bad effects from the punctures. 



F II from apple was used in making inoculation of 42 

 Enchantress buds July 11, 1910. Eight days later, 34 of these 

 were badly decayed, 4 showed a small amount of injury and 4 

 were not damaged at all by the fungus. Eight buds were inocu- 

 lated with F II July 26, 1910, and 11 days later all were rotted 

 while one bud which had been punctured as a check had opened 

 to a perfect flower except for the place broken by the puncture. 



F XV from potato was used in making inoculations of 30 

 Enchantress buds August 18, 1910. None of these buds decayed. 

 September 14, 13 buds were inoculated with the same fungus 

 and 6 of these showed a small amount of rot, although the 

 fungus did not spread through the tissues so rapidly as the dif- 

 ferent strains from apples. 



August 26, 1910, 25 buds were inoculated with F IV and 

 all of these rotted. 



September 15, 1910, 18 buds were inoculaited with F I and 

 30 buds with F III from apple. Of the 18 buds inoculated with 

 F I, II decayed and of the 30 inoculated with F III, 20 decayed 



The fungus, F XIII, with both obovate and septate spores 

 from sunflower was used October 17, 1910, in making inocula- 

 tions of 18 buds of Enchantress. Two weeks later 10 of the 18 

 buds had been destroyed by the fungus. 



The Gomez variety was found to be very resistant to the 

 fungi which caused a rot of Enchantress and other varieties 

 which were used in later experiments. 



Fourteen Gomez buds were inoculated August 26, 1910, with 

 F I from apple. When these were examined 18 days later only 

 one had rotted. 



September 30, 1910, 37 Gomez buds were inoculated with the 

 fungus, F XIII, from sunflower. Only 4 of these buds showed 

 rot after 17 days. 



F II from apple was used in making inoculations of 95 

 Gomez buds November 3, 1910. Observations from time to time 

 indicated that the fungus was not causing decay and that the 

 buds were developing normally. When a careful examination 

 was made November 21 it was found that nearly all the buds 

 had opened into perfect flowers. A few were slightly injured 

 but none hadly rotted.
