486 SUCCESSFUL FARMING 



This fruit is grown extensively in Florida and the West Indies and to some 

 extent in California. While the pomelo has been known for many years, 

 it was first grown on an extensive commercial scale in Florida, first being 

 introduced as a commercial fruit about 1885. The varieties most commonly 

 grown are selected Florida seedlings, though one or two varieties, as the 

 Pernambuco and the Royal, are importations respectively from Brazil 

 and Cuba. Probably the most widely planted varieties in Florida are the 

 Duncan, Josselyn, Walters, Pernambuco and Marsh. The Marsh, which 

 is a nearly seedless variety is the most extensively planted of any variety 

 in California. 



The Lime (Citrus limetta). — The lime is grown throughout the 

 citrus regions of the United States and the West Indies, but is produced 

 commercially only in southern Florida and the West Indies. The demand 

 for these fruits has rapidly increased in recent years and is assuming some 

 importance. The principal varieties grown are the Mexican and the 

 Tahiti. 



The Mandarin Orange (Citrus nobilis). — This fruit, referred to fre- 

 quently as the "kid glove orange" because of its loose, easily removable 

 skin, is grown to a considerable extent in certain regions of the United 

 States. It is in general rather more cold-resistant than the common orange, 

 and this has led to its propagation to considerable extent in the Gulf 

 states. The Satsuma or Unshiu, an early maturing sort of fair size, is 

 grown rather extensively in northern Florida and southern Georgia, 

 Alabama, Mississippi, Louisiana and Texas. The Dancy tangerine is 

 grown to some extent in Florida and California and occasionally in some 

 other states. 



The Citron (Citrus medico). — The citron, the candied or preserved 

 peel of which is a staple article of commerce, is not grown to any extent in 

 America. A grove of about fifteen acres at Riverside, Cal., is the largest 

 and only grove known to the writer in the United States. Another minor 

 citrus fruit cultivated to some extent as an ornamental and for preserving- 

 is the kumquat (Citrus japonica). 



Citrus Regions and their Production. — While the various citrus species 

 are of tropical origin, the commercial development of citrus growing has 

 taken place almost wholly in subtropical countries. The most important 

 countries in the order of their production are the United States, Spain, 

 Italy, Japan and Palestine. The normal citrus crop of the world is now 

 equal to about 90,000,000 to 100,000,000 boxes of California capacity or 

 from 230,000 to 250,000 carloads of California size.* The normal produc- 

 tion of the United States is now about 78,000 carloads; Spain, about 

 68,148 carloads; Italy, 58,000 carloads; Japan, 10,896 carloads; and Pal- 

 estine, probably about 9000 carloads. Small quantities of citrus fruits 

 are, of course, produced in many other tropical and subtropical countries.
