fruit grown under the influence of the ocean breezes. In 

 contrast with some of the important lemon counties men- 

 tioned above, 98 per cent, of the citrus area of Tulare 

 county must be credited to oranges, and most of these are 

 navels. 



The principal citrus counties in order of importance, to- 

 gether with the acreage in 1913, are:*

By consideration of these figures it appears that the im- 

 pression that oranges and lemons can be grown promis- 

 cuously in almost any section of southern California is 

 incorrect. The essential conditions are many and rigid: 

 the soil must be suitable, the area must not be subject to 

 frost or heavy winds, proper drainage must be secured, 

 adequate and permanent sources of water supply must be 

 developed. The result is that within the vast area of south- 

 ern California, almost as large as the state of Illinois, only 

 140,000 acres is devoted to citrus fruit culture. As has 

 been intimated this producing area is widely scattered, and 

 for the most part is confined to the protected valleys of 

 the foothill regions, though some important plantations are 

 found elsewhere. 



Citrus growing in Florida has expanded tremendously 

 in recent years, the greatest growth appearing in the pro- 

 duction of pomelos. Since the Census gives figures for the 

 number of citrus trees in both California and Florida it is
