All of the facts thus far presented, which pertain to the life-histo; y of 

 the hrown rot fungus and its methods of passing through unfavorable sea- 

 sons, emphasize the importance of collecting and destroying the so-called 

 mummied fruits as a means of control. If these infected fruits are allowed 

 to remain hanging to the trees or upon the surface of the ground the conid- 

 ial stage begins its destruction at once the following season, while if they 

 are permitted to become buried beneath the trees, ascospores form the sec- 

 ond season which are capable of producing in turn the conidial stage.
