Oranges Orange culture in California is already the most 



a productive branch of horticultural industry in any 



Golden Crop, state in the country. The annual shipments amount 



to 30,000 carloads, or between 10,000,000 and 12,000,- 



000 boxes, with an estimated value of $20,000,000, less packing 



charges. In addition to this $20,000,000 to the growers and packers, 



the crop pays over $13,000,000 for transportation and refrigeration. 



Associations have been formed to protect and advance the in- 

 terests of the growers of Southern California by co-operation, to 

 exchange information on fruit culture obtained through experiment 

 and experience, and to extend the advice of pioneer fruit growers 

 to those planning to engage in horticultural pursuits in Southern 

 California. 



Uncle Sam The growers have not been unaided in making ex- 

 Chips periments. Considerable sums have been spent in 

 In. scientific investigations by the Department of Agri- 

 culture, through its Bureau of Plant Industry, for 

 the furtherance of the tremendous interests invested in orange culture ; 

 and these investigations have been made particularly with reference 

 to economy in gathering, packing and shipping; that is, the handling 

 of the fruit with a view to a minimum percentage of decay while in 

 transit and upon the market. 



Sources Information gleaned from the above mentioned asso- 



of ciations, from reports of governmental experiments, 



Information. and from other available sources and publications, has 



gone toward making up this little bulletin on orange 



culture sent forth by the Los Angeles Chamber of Commerce. Any 



one wishing to investigate further the subject of orange culture will 



do well to consult the following documents :
