qualities, and California is now producing largely 

 and profitably good olives and olive products. Prac- 

 tically all the counties of the State except those on 

 the high mountains and on the upper northwest 

 coast, have olive trees in bearing, the interior valleys 

 and foothills of the Sierra Nevada leading in the 

 production. 



Imported lemons have met sharp competition in 

 the markets of the United States by the California 

 product. Though lemon-growing is possible in most 

 sections where oranges are produced, the lemon does 

 best in nearly frostless places, being more tender than 

 the orange. For this reason the chief product is in 

 the southern coast counties (Region 3). The lemon 

 is more exacting in production than the orange, which 

 is marketable fresh from the trees, while the lemon 

 requires curing and a good part of the crop has 

 to be held from winter maturity to be sold in the 

 following midsummer, when the chief demand for 

 lemons occurs. 



California has accomplished more with the orange 

 than with any other single fruit, not only largely 

 supplying the United States but successfully selling 

 the fruit in northern Europe. As explained in de- 

 tail in Chapter I, the orange thrives in suit- 

 able situations through a north and south distance 

 of over 600 miles and the topography of the State is 

 such that similar winter and summer temperatures 

 occur all through this distance. By choice of early 

 and late varieties and by using the variation in the 

 season of maturity in different regions, California can
