Picking and Packing Oranges. Picking, Packing and Marketing of Fruit.—The methods of picking, packing and marketing of citrus fruits are probably more highly developedthan in any other fruit industry. The picking is in large measure done bycarefully trained special picldng gangs connected with the packing houses, rather than by the growers themselves. This insuies the most careful workand handling and the employment of uniformly good methods. The curing, grading and packing is also done by specially trained menworking continuously under inspection to insure careful handling at everypoint. The special machinery devised for washing, drying, grading, sizingand boxing has reached a high degree of perfection and is almost univer-sally used in the citrus sections of the United States. The watchword ofall packing houses is careful handling to avoid bruising or puncturing theskin of the fruit and thus prevent decay. 3
