ALMONDS AND WALNUT* 



Fig. 194. — Maps showing trees of bearing age and younger. Each dot is for 100 acres 

 of trees, except in D for 50 acres and E for 500 acres. Lemons are produced principally in 

 southern California, where most of the crop is grown along the foothills on the western 

 side of the Coast Range. Limes in the United States are grown commercially only in the 

 southern tip of Florida and adjoining islands and keys. Grapefruit (pomelo) is grown 

 in Florida, where the fruit attains excellent flavor. The industry is of increasing impor- 

 tance in California. Olives are grown mostly in southern California, west of the Coast 

 Range, in the Great Valley, and in the valleys opening into San Francisco Bay. The com- 

 mercial production of Persian (English) walnuts in the United States is practically 

 confined as yet to California and western Oregon. The production of almonds centers in 

 Contra CoBta County, Cal., and extends up both the Sacramento and San Joaquin Valleys. 

 The commercial orange crop of the United States is practically confined to California 

 and Florida. California has nearly two-thirds of the trees and produced in 1909 about 

 three-fourths of the crop. There are a number of long-established orange orchards in the 

 lower Mississippi delta in Louisiana and in Arizona. (U.S.D.A.)
