Picking and Packing Oranges. 



Picking, Packing and Marketing of Fruit. — The methods of picking, 

 packing and marketing of citrus fruits are probably more highly developed 

 than in any other fruit industry. The picking is in large measure done by 

 carefully trained special picking gangs connected with the packing houses, 

 rather than by the growers themselves. This insures the most careful work 

 and handling and the employment of uniformly good methods. 



The curing, grading and packing is also done by specially trained men 

 working continuously under inspection to insure careful handling at every 

 point. The special machinery devised for washing, drying, grading, sizing 

 and boxing has reached a high degree of perfection and is almost univer- 

 sally used in the citrus sections of the United States. The watchword of 

 all packing houses is careful handling to avoid bruising or puncturing the 

 skin of the fruit and thus prevent decay.
