to absorb additional quantities of first-class sweet oranges at re- 

 munerative prices. (Ariz. E. S. B. 58.) 



Experience has taught that no variety of citrus is pre-eminently 

 useful for all portions of the world where this fruit is grown. As an 

 illustration we have the Bahia, or Washington navel orange, which 

 is pre-eminently adapted for California, but of little value in Florida 

 or the West Indies, since it produces only a small crop except on 

 rough-lemon stock, which stock is only adapted to a restricted area. 

 Certain varieties of pomelo have exquisite flavor when fruited in 

 Florida, but are not of the same excellence when grown in California. 

 The pineapple orange and the Indian River orange are among the 

 finest of fruits when grown in the sections where they originated, 

 but when produced in Jamaica they can not be said to have 

 superior qualities. 



It becomes necessary, therefore, to test the particular variety 

 in the section into which it is to be introduced. Some of the 

 varieties are excellent in places far removed from one another, as is 

 illustrated by the Satsuma, or onshu, an introduction from Japan, 

 and the Bahia orange, which was brought from Brazil by the United 

 States Department of Agriculture and is now so extensively grown 

 in California. The last-named variety produces fruit of excellent 

 quality when grown in Florida, but, as stated, is not prolific except 

 on rought-lemon stock. Frequently the most important varieties of 

 citrus for any given locality are those which have originated as 

 seedlings in that section, and ocasionally they may arise as bud 

 varieties. An illustration of a variety arising as a bud variation 

 is the Surprise navel, originating in Mr. E. S. Hubbard's grove at 

 Federal Point, Fla., from buds received from California. Seedlings, 

 as a rule, "sport," or ate exceedingly variable ; they, however, come 

 true to seed within certain limitations. So far as known, a pomelo 

 can not originate from an orange seed except where an orange 

 flower is pollinated from a pomelo, and it is then not a true 

 pomelo. Seedlings from the mandarin group reproduce a typical 

 mandarin fruit. Seedlings from the sweet orange produce a typical 

 sweet orange. Seedlings from pomelos produce pomelos of varying 

 qualities. (F. B. 238.) 



THE ORANGE. 



The orange is king of the citrus fruits. It may be treated as a 

 type representing the other members of the group in many par- 

 ticulars relating to soils and cultural methods. In some respects 

 special treatment is required for lemons, limes, and pomelos, as 

 described in the sections devoted to these fruits. (Hawaii E. S. 

 B. 9.) 



Climate. In general it may be stated that in all regions in 

 which the temperature does not fall below 18 above zero nor rise 

 above 100 F., and where there is sufficient moisture, citrus fruits 

 may be produced. There are, however, localities within these limi- 

 tations that can not be said to be good citrus-growing sections. In 

 some places, although the trees grow luxuriantly, heavy rainfalls 

 occur at the time when the fruits are maturing, making it impos-
