The Washington Navel, the variety of orange most commonly grown in California, does remarkably well on our rich volcanic scrub soils, where it has proved itself a regular bearer of high-class fruit. The Mediterranean Sweet Orange, Valencia Late, and Jaffa also do well in many parts, the Valencia Late adapting itself to most districts. Many other kinds of oranges are grown, but the varieties mentioned are some of the best, and are the ones now being planted in the greatest quantity. [Illustration: Spray of Orange Blossom.] In mandarins, all kinds do remarkably well, and I never saw this fruit produced to greater perfection in any part of the world than it is in Queensland. The varieties most commonly grown are: The Emperor or Canton, the Scarlet or Scarlet Emperor, Thorny or Tangerine, and Beauty of Glen Retreat, though there are many types of seedlings in addition to these well-known sorts. The grape fruit which is now so popular in America does well, but, so far, has not taken on in our markets. Citrons grow practically wild, and produce good fruit, for which there is a limited demand for peel. Their cultivation could be extended with ease were there a better demand for peel. The Seville Orange, which is used for the manufacture of marmalade, is an exceptionally hardy and prolific tree, and, were it required, we could easily grow enough of this fruit to supply the world. Lemons do best inland, or at an elevation of some 2,000 feet above sea-level, as this fruit is apt to become too coarse in the skin when grown in a humid climate. In suitable localities very good fruit can be grown, which compares very favourably with the European or American grown fruit. The lime does well in the more humid districts, taking the place of the lemon, and one variety--the Tahiti--has proved itself to be a heavy and regular bearer. The West Indian lime, from which the lime juice of commerce is made, is very easily grown, particularly in the more tropical parts, where it is often met with growing in an entirely uncultivated condition, and bearing heavy crops of fruit. Kumquats are easily grown, and are heavy bearers, and all the different types of pomelos or shaddocks do well. Seedlings of the latter are very hardy, as they are deep-rooted plants that stand dry weather well and are, consequently, not liable to injury during dry spells. There is very little demand for the fruit, but I am of opinion that the seedlings will prove to be of value as stocks on which to work our best kinds of oranges.
