1 Green, 



In conclusion, organization is needed among fruit-growers in the 

 matter of protecting their fruits at critical periods as much as in any 

 other matter that affects them. The fruit-grower who will not smudge 

 at a critical period when his neighbor is smudging, is, whether he knows 

 it or not, getting certain benefits from his neighbor's work, while doing 

 his best to handicap that neighbor and prevent the successful issue of 

 that neighbor's efiforts. I am glad to say that the citrus-fruit growers, 

 and especially those of the Riverside district and members of the Horti- 

 cultural Club, have always been to the front in this matter of frost- 

 fighting, have organized frost districts, and I believe are ready this year 

 to attempt to protect their oranges by concerted and well-directed action. 

 I wish to strongly urge the deciduous-fruit growers to emulate the 

 example of their brethren of the South. 



A vote of thanks was tendered to Professor McAdie for his very 

 interesting address.
